The Internet is an integral part of our life. Lack of network is a serious problem for the user. You don't always have time to call your provider, but, fortunately, you can troubleshoot problems yourself. Below you will read about common causes of Internet problems and how to fix them.
Possible reasons for the lack of Internet on Windows 7
There are several reasons for the lack of Internet. Some of them relate to computer drivers and its equipment, others affect system errors and the lack of correct network settings.
The most common reasons for lack of Internet:
- mechanical damage to the cable or ports;
- lack of a network card or its drivers;
- incorrect connection settings on the computer or router;
- presence of virus software.
The Internet may also be unavailable due to a debt on a personal account or due to a line failure. Before you try to troubleshoot problems, check to see if these issues are causing them.
How to check network status
Among the problems with the Internet, we can highlight those that are most common and occur periodically for most users. Resolving them can be very simple. The first thing to do is check the network status.
You can do this in two ways:
In both cases, your network status will be described below your network icon.
Unidentified network without internet access
If the computer “sees” the network and connects to it, but does not gain access to the Internet, the network status will be called “Unidentified network. Without access to the Internet." What to do in this case?
The computer “sees” the network and connects to it, but does not gain access to the Internet Reboot the router
If you have a router installed, the first thing to do is reboot it. It may simply not have time to update the data, and because of this, access to the network will be lost. The reboot is performed in the following order:
- First, the router is disconnected from the network. It is important to unplug the cord from the outlet, and not to reboot using the button on the equipment - you need to stop the flow of electricity for a while.
- Then the router should be left turned off for 10–15 seconds.
- After this, the router is connected back to the network and wait until the indicators on it light up.
After the indication appears on the router, you can check whether Internet access is available. Usually, after a reboot, the Internet appears within 7–10 seconds.
Checking network settings
Network settings are data that allows the computer to connect to the network distributed by the provider. These settings are issued by the company providing Internet access (usually they are specified in the service agreement). Sometimes the settings on your computer go wrong, and because of this, the device cannot connect to the Internet.
In order to check the network settings, you need to open “Protocol Properties”. You can do it like this:
- Go to “Control Panel” through the “Start” menu.
"Control Panel" is located in the right "Start" menu - Select "Network and Internet".
In order to find the desired section, you should select the “Category” viewing option in the upper right corner of the screen - Open the Network and Sharing Center section.
In the Network Control Center you can check the connection status, create a new network, and carry out almost any action with your Internet connection - On the left, find the “Change adapter settings” section.
Find the section "Change adapter settings" - In the list of networks, select the one you need, right-click on it and find “Properties”. Only an administrator can open Properties.
The desired network will be called “Local Area Connection” or “Ethernet” - In the list, find the item “Internet Protocol Version 4”, select it by pressing the left mouse button once. After this, the “Properties” button under the list is activated, you need to click on it.
Selecting an item is done by clicking the left mouse button once. There is no need to uncheck the box next to the item.
When the window is open, you still need to understand what settings should be entered. There are three options:
Let's figure out what the IPoE and PPPoE protocols are, but we won't go into terminology. It is enough to understand what protocol is used on your communication line. To do this, just look at the network settings issued by the provider (specified in the contract).
The settings can be the following:
- password and login are used on the PPPoE protocol,
- IP address, subnet mask, gateway and DNS are used on IPoE.
If you are using PPPoE and you are connected directly, that is, you are not using a router, after checking the settings through the protocol properties, you need to recreate the network.
- Return to Network and Sharing Center.
This way only PPPoE connection is configured. To configure a wired IPoE connection, use the protocol properties - Open the “Create and configure a new connection” item.
Switching items is done by single-clicking the left mouse button - Select "Create and configure a new network" and click "Next".
The selected item will be highlighted with a bright blue background - Click on the "High Speed" option.
It may take several minutes to wait while searching for available connections - If an error appears, select “Create the connection anyway.”
This error appears quite often, but the connection can still be created - Next, you will need to enter the network settings, as well as the network name - this is the name of the connection. You can use the name of the provider company or something else.
The connection name is its name, and the username and password are the network settings. It's worth noting that the password has nothing to do with the Wi-Fi key
After this, the network will be reconfigured, and you will only have to check whether you have access to the network.

Resetting TCP/IP Settings
Sometimes problems can be caused by internal system errors. TCP/IP is a set of network protocols responsible for data transfer. You can reset it as follows:
Checking drivers
The reason for the lack of access may be outdated drivers (usually this problem is associated with a recent update of the operating system). Let's check their condition.
In addition, by right-clicking on the driver name, you can select “Uninstall”, and then restart the computer. Then when you turn on the system will automatically install the missing driver.
After removing the drivers and restarting the computer, the system will automatically install the appropriate drivers If there is an exclamation mark next to the driver icon, you will need to completely reinstall the drivers and check the functionality of the network card installed in the computer.
The default gateway is not available
Network diagnostics will help you detect the following problem. Right-click on your connection icon and select “Troubleshooting”.
By right-clicking on the icon you can open the “Network and Sharing Center” If you receive a message about the gateway being unavailable after performing a system diagnostic, the following steps may help.
Prohibit disabling the network adapter to save energy
Sometimes the system turns off the network adapter - the device that allows you to connect to the Internet - to save power. Try disabling this option.
- Find "Device Manager" through the search bar in the Start menu.
Opening "Device Manager" through search is not the only way, but it is the most convenient - Expand the “Network Adapters” tab, select the one you need, and right-click on it.
In the context menu, click on “Properties” - Select "Properties" and open the "Power Management" tab.
Changing these settings will help solve the problem of the Internet disconnecting after the computer goes into sleep mode - Uncheck the box next to “Allow the computer to turn off this device to save power” and save your data.
After changing the settings, do not forget to save them by clicking on the “OK” button
Updating or reinstalling drivers
You can also update drivers through Device Manager: expand the Network Adapters tab, right-click on the network driver and select Update or Uninstall, then restart your computer.
If the action does not help, you can download drivers from their manufacturers' websites and install them yourself. Typically, manufacturers offer to download drivers in an “.exe” file format, so to install, you only need to run the downloaded file and accept the agreement.
Video: how to reinstall drivers yourself
When connecting to the Internet through a router, error 651 occurs
This error occurs when trying to connect using the PPPoE protocol. It is rare, but it happens that users create a new high-speed connection while the provider is using the IPoE protocol. Therefore, first of all, make sure that you are using the PPPoE protocol.
After this, you will need to recreate the connection. The process is described in detail in the “Checking network settings” section (all you need to do is create a new connection through the “Network Control Center”). If this doesn't help, read on.
Disabling antivirus
Sometimes antivirus programs block access to the Internet. Often the solution to the problem is to disable the antivirus. Right-click its icon in the Control Panel and select Disable. Sometimes antiviruses block access to the network even in a “sleep” state, so you can try not only disabling, but also completely removing this software. If this action helps, please report the situation to antivirus technical support.
Problems with the router
The cause of the problems may be several problems related to the router:
- incorrectly connected cable;
- incorrectly entered settings.
First try the following:
- Disconnect the router from the network.
- Without connecting the router, unplug the network cable from it and plug it back into the WAN/INTERNET port, making sure that the plastic clip on the plug clicks when connected.
- If the cable goes from the router to the computer, disconnect it from the LAN connector on the router itself and from the network card connector on the computer, and then connect it back.
- Connect the router to the network.
If access does not appear, check the network settings entered on the router. In order to log into the router, you will need to enter “192.168.1.1” or “192.168.0.1” in any browser (in the address bar). Sometimes the address at which you can log into the router is different, so if you cannot log in through the specified addresses, check the information in the instructions.
Files cannot be downloaded from the Internet
It may also happen that Internet access is active, but files are not downloaded. This problem is usually associated not with the Internet itself, but with the computer and software.
What you can try:
- try to download a file from another source - perhaps you are unable to download something simply because the resource does not support downloading;
- try downloading through other browsers;
- check your computer for malware using any official antivirus.
Multimedia does not work on the Internet
It happens that the Internet works, but video or audio materials are not played. What to do in this case? First, check if the files downloaded to your computer are playable. Perhaps the cause of the problem lies directly in the computer's sound settings. If files are played from your computer, but not from the Internet, read on.
The first thing you need to do is understand why this problem occurs. It may be a browser error or lack of plugins. To get your computer working properly, do the following:
PPPoE diagnostics
Additionally, in order to find out the causes of errors when using PPPoE, you can use the Troubleshooting Center. Then the system will independently check for errors and offer possible solutions.
PPPoE (Point-to-Point Protocol over Ethernet) is a communication protocol over an Ethernet network that operates on a point-to-point basis and provides the user with a number of capabilities: encryption, authentication and data compression. It is necessary for the user authorization system, which makes it easier to track the time of provision and payment of network services.
Right-click the network connection icon and click the Diagnose Problems button. After this, an analysis will be performed, Windows will try to cope with the difficulties on its own, and then prompt you to perform several actions.
Error 619
Restart your computer and disable all security systems: antiviruses and Windows Firewall. The latter is disabled in the following way:
Error 633
There is only one solution:
- Restart your computer.
- Try connecting to the Internet again.
- Create a new connection.
Error 638
Main causes:
- damage to the network cable;
- malfunction of drivers or network card;
- incorrect connection settings;
- problems with network equipment (router);
- presence of viruses on the computer.
First of all, do two things: check the integrity of the cable and the presence of indications on the router. Never neglect these steps when you have problems with the Internet, so as not to waste time trying to solve a problem caused by mechanical damage.
It is clear that if the cable is damaged, you need to call your provider. But if there is no indication on the router (which indicates that the device is de-energized), you should try reconnecting the router to a different outlet before replacing it.
After checking the functionality of the router and the integrity of the cable, check your computer for viruses with any antivirus program.
If the above does not help, recreate the network connection - check the correctness of the entered settings both on the router through its settings, and on the computer itself through the protocol properties. Both actions are described in detail in the previous paragraphs of the article.
Error 691
The only reason for error 691 to occur is an incorrectly entered password and login (network settings). Therefore, the first thing you need to do is recreate the connection. The process has already been described earlier - you need to go to the “Network Center”, select “Create a new connection” and then enter the correct network settings. After this, restart your computer and check your internet connection.
If the action does not help, report the problem to your provider. There may have been a line failure that caused the error.
Error 720
The easiest way to solve this problem is to reinstall the operating system. To do this, just download the operating system file to disk from the Windows website (or purchase the disk in the store) and run it on your computer.
You can also try updating the TCP/IP protocol. The action is described above, but you can also perform a deeper operation by completely reinstalling the stack. Reinstalling the stack yourself is dangerous - you will have to work with system files, and their damage will affect the operation of the computer. Therefore, try simply updating the stack, and if the action does not help, contact your provider or professional technician for help.

Network cable not connected
If, when checking the connection status, a message appears that the network cable is not connected, the first thing to do is actually check that it is connected correctly and is not damaged. If possible, try using a different network cable.
Make sure the cable is connected correctly. On the router, the network cable must be connected to the WAN or INTERNET port, and the cable leading from the router to the computer must be connected to the LAN connector. There is usually only one port on a computer, so it will be difficult to make a mistake.
The WAN or INTERNET port is used to connect a network cable to the router, and the LAN ports are used to route cables to computers Next, check the status of the router (if you have one). Its indicators should light up as usual. If there is no indication, reconnect the router to another outlet, try resetting the settings on the router (using the “Reset” or “Reset” button) and entering them again. You should reset the settings only if you are confident that you can configure the router yourself.
Also check the status of your network adapter drivers and try updating them.

Additional check of security settings
Security settings can also be to blame for many of these problems. This applies to the case when the PPPoE protocol is used. Therefore, if the proposed operations do not help solve your case, try checking your connection security settings.
- Open the "Network Connections" section.
- Right click on your connection.
- Open the “Security” section and set the use of “Unsecure Password” in the list that opens.
These are the main ways to diagnose connections on Windows 7 and troubleshoot problems. Do not forget that the reason for the lack of Internet may be a simple debt or a breakdown on the line. If the methods described above do not help you, contact your provider so that technical staff can diagnose and solve the problem on their end.
What to do if the Internet is working, but pages don’t load, sites don’t open, you can’t look at it, and you can’t write a term paper?
So that such a situation does not take you by surprise, this article was written!
Most likely, your Internet is connected either through a cable from or a wireless network.
We will look at possible solutions for each of these cases.
What does a connected internet look like?
First, let's figure out what the icons look like when the Internet is connected. Typically, the following icons appear on the lower right side of the screen:
In the form of a “Christmas tree”- if you are connected using a Wi-Fi network - i.e. without the use of fiber optic cables.
Second option- in the form of a computer - if connected via cable and telephone network.
If you have a connection using a router and cables
This connection method is more convenient for a home computer - you can only connect via . Of course, you can get around this by purchasing an external one - this will help avoid the sight of a lot of wires - but if for some reason you prefer this method, we will look at it in detail below.
Most likely your problem looks like this: when you connect the network cable that was sold with the router and your computer, the Internet does not appear.
If this is the case, first answer yourself a few questions:
- does the Internet work on another computer using this cable and? Perhaps the problem is a malfunction of the components themselves - check on another computer - if the Internet also does not work, it is better to contact a service center under warranty.
- Does the Internet connect to the computer when connected directly without using a router? This will also help determine that the root of the problem lies in a faulty router.
- Is the light on the router blinking?
- What does your PC show? These could be phrases like “the network cable is not connected” - i.e. the connection indicator does not change before and after connecting the cable; or continuous system identification may occur.
The desktop computer does not respond to connecting the LAN cable, “no connection to the network”
The situation is this: you connected a working cable to the computer and it does not respond to it and displays a message like in the photo:
In this case, we look for the problem in every link of the chain: in the cable, in the router, or in the personal computer/laptop.
You need to perform a few simple manipulations to install this:
- make the same connection using a different cable (if the problem persists, it means your first cable was working);
- then connect the router and the previously tested cable to another computer/laptop (if everything works, then the problem is in the network card of the personal computer/laptop. It is part of the package. If everything doesn’t start working on the other computer, then we’re looking for a problem in the router) ;
If after such simple manipulations you suspect that the problem is in the network card of your computer/laptop, don’t worry!
You don't have to buy a whole computer from scratch” - it will be enough just to replace the network card with a new one - the good news is that they are inexpensive.
You can clarify this problem if you go to the task manager of your personal computer\laptop in the network card section - If there is a malfunction, there will be an exclamation mark above it.
Just in case, check that your local network connection is enabled.
How to set this up, see the photo below:
Thus, we checked all components of the chain (router, cable, personal computer\laptop), most likely found and eliminated the causes of the malfunction - the Internet should appear.
Long-term network identification without Internet connection
Another difficulty often occurs: you connect the network cable to your PC/laptop, “network identification” is displayed - and the long-awaited Internet does not appear.
This is most likely due to IP (Internet Protocol) addresses. Or you previously had an IP address configured on your computer from an old connection - and you need to make a connection to the router with this IP, or a DHCP (Dynamic Host Configuration Protocol - router system that helps automatically generate an IP address when connecting) router server - it does not can give you an IP address.
What to do?
At first- set automatic IP and DNS acquisition.
You can also define a static IP address, similar to what was described above.
In Fig. 11 in the “Properties: Internet Protocol” window you see the line “use the following IP address”.
Select it and write your IP. Please note - if your access is by address, then you can indicate, for example, the address 192.168.1.60 ; If 192.168.0.1 , then the address will be 192.168.0.60 , DNS can be like this: 8.8.8.8 And 8.8.4.4. and so on (these are examples for general presentation).
Yellow exclamation mark (connection and lack of access to the Internet).
What's on your screen:
This problem is due to incorrect router configuration.
Here you need to look in detail at setting up the router to work with the provider, setting a password, and specifying the provider’s settings.
First, determine what technology your router uses:
- Dynamic IP
- Static IP
- PPTP/Russia PPTP
- BigPond Cable
- L2TP/Russia L2TP
- PPTP/Russia PPTP
Usually you can choose the technology yourself - Additional parameters of the provider when connecting depend on this:
Look in the documents, on the provider’s website, or just call the support service. When calling, please clarify that you are setting up the Internet on a Wi-Fi router and want to clarify what type of network and settings to specify in the router.
There is a connection, but no surfing
This sad picture is probably familiar to many.
These screenshots were taken from different browsers- messages from different browsers may differ, but they usually write. that it is impossible to open the site, display the page, there is no Internet connection.
First of all, look at the Internet connection icon (on a computer - at the bottom right side of the screen).
There may also be a system message detailing the problem itself.
DNS problem.
Briefly about the DNS system. This is a program that converts our requests into digital addresses that the browser can understand for searching the Internet.
Accordingly, if this system does not work, the search itself will not be able to be carried out.
This could be a problem with the site itself (if other sites open normally and there are problems with only one).
To install this, enter any other site into the search query of your browser, or better yet, another browser and look.
This can be due to problems with the router - to fix this problem, you will try to dial the same site from other connected devices - for example, from a mobile phone. If the site doesn’t work from your phone either, it’s more likely a problem with the router. If the site opens from the phone, but not from the computer/laptop, then the problem is in the computer - see below how to solve it.
- set startup to “automatic”
Then, right-click on the service again, and select "Restart". Restart your computer.
- signs as in the photo (see Fig. 19).
This means there is no Internet connection. Step-by-step instruction:
- reboot the router
- Carry out a full scan of Windows networks (connection icon - right-click - troubleshooting - click).
- Perhaps there is a problem with the provider. Call support
- remember if you have recently installed any third-party programs
- surf different sites from different web browsers - there is a chance that only one site will not load.
- if the browser does not load pages - try changing DNS
Register DNS from Google: go to network connections (Win + R key command), click on the connection through which you are connected to the Internet and select “Properties”.
In the new window, highlight “IP version 4 (TCP/IPv4)” and click on the “Properties” button.
Reset network settings.
In Windows 10, this is done through the settings: Open “Start”, and go to “Settings” ↠ to the section "Network and Internet"↠ On the “Status” tab, click on “Network reset” ↠ Click on the button "Reset Now"↠ Confirm the reset by clicking “Yes”.
In , you can reset parameters using commands that are written on the command line on behalf of the administrator:
ipconfig /flushdns
ipconfig /registerdns
ipconfig /renew
ipconfig /release
Execute these commands one by one, and then restart the PC, if the result is the same - return to factory settings.
- Scan your PC for viruses. You can download both free and paid ones online – and then scan your PC
- If you had an antivirus program installed and scanning your PC did not detect the presence of malware, temporarily turn off the antivirus program; it could independently change some Internet access settings.
We tried to briefly describe the main problems of connecting to the Internet and ways to solve them.
Usually, all problems lie on the surface and can be identified independently without the participation of a specialist - this is exactly what our article serves.
You may find out additional useful information from the video (links will be provided below).

The Internet is full of news about how to solve the problems of connecting to the global network using wireless technologies. However, even when connecting to a wired Internet, a lot of problems can arise that will not allow you to receive information from the global network, although they are much less common. If the Internet does not work via cable, the user must clearly know the reasons, as well as ways to solve this problem.
This article discusses the issue of problems accessing the Internet by directly connecting a LAN cable to a computer or laptop, from a router (directly connecting a cable from a provider is practically no different, only in this case there are slightly fewer reasons for inoperability).
As a rule, the network cable is connected directly to the computer due to the fact that it does not provide for such components and are not connected. Of course, you can purchase a special Wi-Fi receiver that can be connected to the Internet to get rid of unnecessary wires located around your apartment, house or office. But this step is not always advisable, because a computer is in no way a portable device that can be moved at any moment. That is why, in order not to spend extra money, most computer users use a direct LAN connection.
First of all, if you cannot connect to the Internet, you need to check the following factors:
- Is the cable that connects the router to the computer working (try using it when connecting to another device);
- check the functionality of the Internet channel (connect directly the LAN from the provider to the network adapter);
- whether the connection to the router is active (whether the LAN light on the router is on);
- pay attention to the network icon, which is located in the tray (at least somehow the computer reacts when connecting and disconnecting a network cable, and also whether the network is identified);
The above factors are the main reasons for the lack of Internet connection. If the LAN cable connecting the router and computer does not work, it is enough to replace it. If no devices, with a direct cable connection from the provider, also gain access to the Internet, this issue must be checked directly with the provider, who are required to check the integrity of the cable along the entire route, from the computer. Of course, if the LAN cable connection light on the router does not light up, you need to check the connection and functionality of the router itself.
The most unobvious problem is the inability to connect to the Internet, if there is a red cross on the network identifier in the computer tray or a permanent network identification is made that does not allow connecting to the Internet. Let's consider this issue in more detail.
The computer does not respond at all to connecting the LAN cable
If the red cross on the network icon is constantly lit, the reason is the functionality of the network card.
To check your network card, follow these steps:
- open "Device Manager"
- right-click on “My Computer”
- "Control"
- go to “Device Manager”).
You will see a list of all devices installed on your computer. Open the “Network adapters” list, where you will see all the network cards that are installed on this computer (in most cases there is one, which is integrated into the motherboard, but there may be more).
If there is a yellow icon with an exclamation mark next to it, you need to reinstall the drivers for this device. Visit the manufacturer's official website and download drivers for your specific network card model and install them (it is better not to use the automatic search for drivers, but to do the installation manually).
If the Internet is still unavailable, do the following:
- go to “Control Panel”
- go to the “Network and Internet” window.
- Your installed network device may simply be disabled. To enable it, right-click on the icon and select “Enable”.
The Identification circle is constantly spinning or the network is not recognized
This reason may occur when there is a conflict between IP addresses that are present on the network.
To resolve this issue you must:
- go to the “Network and Sharing Center”;
- click “Change adapter settings”;
- Right-click on the icon of your network card and select “Properties”;
- place the cursor on “Internet Protocol IPv4”;
- set a bullet to automatically obtain an IP address and DNS server.
If you have a yellow triangle on your network status, then you have incorrect router settings that do not allow you to connect to the global network.
In such a situation, you need to install the correct router settings (instructions should be posted on the provider's home page, or they can give them to you as a printout) or take the router to the provider so that they can configure the device correctly. Also, a similar sign may appear if you have not paid for the Internet and you are simply disconnected from the network.
Quite often it happens that for the time being everything seemed to be fine with the connection, but at one “wonderful” moment suddenly access to the World Wide Web disappears. It is very difficult to immediately say why the Internet does not work. There could be many reasons for this. Now we will try to find out what these reasons are and how to fix the problems that arise.
Why doesn't the Internet work on my computer?
First of all, you need to pay attention to some factors that affect your network connection. No matter how trivial it may sound, one of the reasons may be a simple cable breakdown (if a direct connection is used). Often there are incorrectly specified settings, situations with incorrectly installed drivers, and even failure of the network card.
Why doesn't the Internet work on a tablet, phone or laptop that has built-in Wi-Fi modules for wireless communication? This usually only has to do with settings. In some cases, when not Wi-Fi, but a mobile network is used for access, the reason may be the corresponding parameters of the selected network, or the problem may lie in the work of the operator itself. But first things first.
Pre-check
So, the user wondered why the Internet does not work on the computer. Let's see what diagnostic actions need to be performed initially.
As mentioned above, you should first check the network cable, and not even on your computer, but on another workstation. If you are using an external Wi-Fi device, you should try to plug the cable from it directly into the computer (into the network card connector). In this case, you should pay attention to whether the network indicator is displayed in the system tray. There may be several options: there is no connection, there is a connection to the network, but without access to the Internet, or an unidentified network was found. The last option is more related to a wireless connection.
In any case, to find out why the Internet is not working, you will first have to check some basic parameters and settings.
Driver problems
So, the first thing you need to do is go to the “Device Manager” in the “Control Panel” and look at the status of the network card. If it is marked with a yellow exclamation mark, the problem can be twofold: either the corresponding drivers are installed incorrectly (or not installed at all), or the device has failed for some reason. It’s worth mentioning here that even with minor defects the system can detect the card, but it won’t work.
As is already clear, you need to try to reinstall or update the device drivers. This is done through the properties menu, which has several basic buttons, but it is better to use the original driver disk that came with the purchase of the device. In some cases, a regular update may be required. This is done either from the same menu indicating the source, or manually, for example, from a downloaded distribution. There is no talk now of automatic programs capable of searching for the latest drivers on the Internet - the Internet does not work.
Problems with settings
Now let's see why the Internet does not work if the drivers are installed correctly. It is very likely that the settings are set incorrectly. Let's consider the case of direct connection.
Here you need to check all the parameters and their values that were provided by the provider when connecting. If automatic acquisition of an IP address is not used, the provider settings should be entered in all fields. This is the IP address, subnet mask, gateways, DNS servers, WINS if used, proxies, etc.
In the case of a wireless connection using an external Wi-Fi receiver, the problem may also lie in the settings of the router itself. As is already clear, here you need to check its parameters by connecting it to a computer (the settings are accessed through any Internet browser by entering the value 192.168.1.1 in the address bar in most cases).
It goes without saying that if you use a modem connection, you will have to worry about setting up the modem.
It also happens that the tray icon is indicated by a yellow triangle. This means that there is a connection to the network, but not to the Internet. You can simply try rebooting the system or router. But the problem may also be related to the provider service itself, or even to the fact that the user simply did not pay for the services provided on time.
Why doesn't the Internet work on my phone or tablet?
Now a few words about mobile gadgets. As a rule, most of them have built-in Wi-Fi receivers. The problem here, why the Internet does not work on a phone or tablet, boils down to the fact that the wrong password was entered when connecting. If everything is correct here, it may very well be that the problem, again, lies in the distribution router, and not only in the settings, but also in the weak signal.
It’s another matter when wireless communication is not used, but instead access to the network is carried out through a mobile network. As an example, let’s look at why MTS Internet does not work (however, this also applies to other operators).
In the settings of your mobile gadget, you need to go to the main settings and in the mobile network selection menu, go to the menu, which is most often designated as “APN access point”. Here the appropriate profile is selected (in our case, this is “MTS-Internet”), and the authentication type column is set to “No”. However, you can easily order automatic network access settings from any operator, which will be sent to the corresponding number in the form of a push message.
Conclusion
In conclusion, it is worth saying that the question of why the Internet does not work is discussed quite briefly, since in each specific case there can be a lot of reasons why such situations occur. And not just one, but several at once. Therefore, solving this problem must be approached with all seriousness. However, even such simple tips and recommendations will help any user identify the causes of failures and eliminate them using the simplest methods.
We always write about solving some problems that arise when connecting to the Internet via Wi-Fi. But, when connecting via a regular network cable, everything is not always smooth either. Yes, there are fewer problems with this connection, but I have already seen questions in the comments more than once about problems when connecting via a LAN cable.
In this article, we will try to figure out what problems may arise when connecting a regular desktop computer, or laptop (netbook) to the Internet via a network cable, through a router.
Precisely when connecting through a router. If you directly connect a network cable from your provider, then this will be a slightly different case, and different solutions.
When I wrote an article on how to connect a computer to a router via a network cable (LAN), I talked about solving some problems. In this article, I want to dwell on this in more detail.
As a rule, desktop computers are connected via cable, since they do not have built-in Wi-Fi receivers. But this problem can be very easily solved by purchasing an external Wi-Fi receiver. A very good way to get rid of unnecessary wires, which, in the case of connecting via a network cable, will have to be laid from the router to the computer.
So, the situation is this: you take a network cable (which, for example, was included with the router), and use it to connect your computer (laptop) to the router. Everything is connected, but the Internet on the computer does not work.
What you need to pay attention to:
- Does another computer work through the same cable and from this router?
- Does the Internet work on a problem computer if you connect it directly, without a router.
- Is the LAN indicator on the router lit?
- What is the connection status on the computer. It may not change at all (for example, “Network cable is not connected”) and may not respond in any way to the connection of the network cable. Or there may be permanent identification.
These are the most popular problems and nuances that you need to pay attention to. We will now look at how to solve them in more detail.
We connect the cable to the router and computer, into the network connector, but there is no response. Connection status (in the notification panel), computer with a red cross “No connections available”, which is displayed when the network cable is not connected, does not change in any way after the cable is connected.
There may be a problem with the router, the cable, or the computer. More precisely, in the network card, which is usually integrated into the motherboard. This is very easy to figure out: just connect a cable from your Internet provider to your computer, not through a router. If there is a reaction to the connection, then most likely everything is fine with the network card. Or connect another computer to the router using the same cable. In this way, we will find out what the problem is.
If the computer does not respond to any cable connections (from different sources), then it is possible that the problem is with the network card. You can buy and install a new one, they are not expensive. Also, go to device manager and see if the network card is there.
Your name may be different. If there is an exclamation mark next to it, it means it is not working correctly. Try reinstalling the driver. You just need to download from the manufacturer’s website and run the installation manually, and not through the task manager.
It may also be that the LAN connector on the router does not work. It can also burn out. Try connecting the cable to all 4 LAN connectors (usually there are 4 LANs on the router).
If you have connected several devices to the router via a network cable, and the Internet does not work on any of them, then it is obvious that the problem is with the router. Provided that the cable is working and tested. Perhaps it's something in the settings. Try resetting the settings and setting up the router again.
The main thing is to find out what the reason is.
It may also be that Local Area Network Connection is disabled. Need to check.
Go to , right-click on and select Turn on(if it is disabled).
After these steps, the Internet should work.
Status “Identification...”, or “Unidentified network” (without Internet access)
Another very popular problem, or even the most popular. We connect the network cable to the computer, and the notification panel displays a constant status "Identification…"(without network access).
Or, the connection status becomes “Unidentified network”(without internet access).
As a rule, such errors occur due to problems with IP addresses. Or, the IP is already registered on the computer (for example, from an old connection), and there is no connection to the router with this IP. Or, the DHCP server is disabled on the router, and it cannot give you an IP. In this case, you need to try setting automatic IP and DNS acquisition, or setting these parameters manually.
First, try setting automatic IP and DNS acquisition. Let's go to Control PanelNetwork and InternetNetwork Connections, or like this:
Right-click on LAN connection and choose Properties. And then we do this:
Pull out and plug back in the network cable. The Internet should work immediately.
