Today we will try to figure it out actual question- a loss Wi-Fi networks. Almost everyone has encountered this situation and asked themselves the question of why the laptop does not connect to the Internet via a wireless connection.
There may be several reasons for the failure, as well as solutions to this situation.
We will discuss different solutions to this problem in detail in this article.
Why can't I connect to the Internet via Wi-Fi?
Let's say Wi-Fi is connected to the laptop, but there is no Internet. There may be several reasons for this problem:
- Problems with the access point (the router has failed, the provider is performing engineering works);
- Problems with the device (Wi-Fi on the device is faulty, the drivers have crashed).
Different devices display fault statuses differently. On a laptop, the Wi-Fi network status bar may display Exclamation point, which indicates a connection failure.
On Android devices, the Wi-Fi icon changes color from blue to gray.
Regardless of the type of warning, you should check the functionality of your Internet connection using a browser. If there is no Internet, an error will appear.
How to connect the Internet to a laptop via Wi-Fi
Connecting a PC occurs in several stages:
Now go to the browser to check:
Everything works, which means the connection was successful.
Operating system Windows 10
On computers with Windows OS, the connection is a little easier:
What to do if there is no network icon on the panel?
Sometimes there is a situation in which the Wi-Fi icon is missing. In this case, you need to do the following:
- Open “Control Panel”;
- Go to “Network and Internet” / “Network and Sharing Center” shared access»;
- Go to “Change adapter settings”.
There will be several connections in the window that appears. You must select “Wireless Network” and click on it right click mice.
Select “Enable” from the drop-down menu. After this, the icon will appear on the bottom panel.
Lack of drivers
Another reason for the absence of an icon may be driver incompatibility or incorrect installation. This problem is quite rare and can be solved by reinstalling the drivers that come with the laptop. The process is automatic. After starting the disk, the system itself will offer to install necessary drivers.
Error: "Windows could not connect to Wi-Fi"
The most common problem occurred in laptops with Windows version 8 and 10. If your network flatly refuses to work, try connecting to another network. For example, with friends, or distribute a connection with mobile device, using modem mode. This method will help determine the malfunction.
If the connection is successful, you can diagnose a laptop malfunction. This means that the cause of the problem is in the router itself.
You should check the connection to the router from another device. If you successfully connect another device, you should check the IP addresses of the laptop. To do this, in “Changing adapter settings” you need to right-click on “Wireless Network” and select “Properties”.
The correctness of the connection can be determined by the packets sent and received. If one of these areas has a value equal to “0,” then there is an obvious conflict between the IP addresses or the devices themselves.
The solution to this problem is to switch the device to automatically receive IP addresses. In 99% of cases, the problem is resolved after applying the parameter.
But, if there is no connection on all devices, you should blame the router. First, you should try updating your device, if you have one. a new version firmware. You can call technical support manufacturer. They will be happy to help you update your gadget.
If the update does not help, then you should contact service center. The average lifespan of a router is about 5 years. After this period, it is recommended to replace the device.

Device incompatibility
Currently, this phenomenon is extremely rare, but still occurs. The reason for this is the manufacturer, who initially does not set the correct compatibility algorithm for various devices. There may be no connection on the PC, and mobile phone connect easily. The reason is the incompatibility of devices. Updating drivers or installing a patch that will allow you to use the device without problems will help eliminate the lack of Internet.
Drivers
But the problem with drivers is not uncommon. Outdated computer adapter drivers can create many connection problems. You can update drivers in several ways:
- Using a helper program. Driver Pack Online is a popular program for Windows designed to solve driver problems. It automatically finds all the necessary drivers, downloads them and installs them at the user's request. The program interface is simple and intuitive. The program is absolutely free.
- With the help of an assistant Windows updates. He helps in automatic mode find and install updates. But it has some disadvantages:
- Limited number of drivers;
- The search takes a lot of time;
- The system is extremely unstable;
Thanks to such assistants, the search process will be reduced to a minimum and will not require unnecessary actions from you.
Conclusion
Most users experience connection errors. For some, this problem occurs once, while others suffer on an ongoing basis due to incompatibility with the device and lack of updates. I hope that with the help of this article you will be able to solve the problem of why the Internet on your laptop disappeared via Wi-Fi.
Video instruction
If you still haven't found a solution to your problem, perhaps this video will be useful to you.
There are many reasons why a laptop won't connect to a Wi-Fi network. In this article you will find a guide to solving the main options for this problem.
Why doesn't my laptop connect to Wi-Fi?
The most common problems with connecting to wireless network occur in the following cases:
- router settings are incorrectly set (broken);
- deactivated wifi adapter on a laptop;
- The driver for the adapter is missing or damaged wireless communication;
- The Wi-Fi module of the laptop has failed;
- operating system failures.
The laptop does not connect to the Wi-Fi network - what to do?
It is worth noting that most often problems with connecting to a wireless network are incorrect settings router. It is its parameters that should be checked first.
Check the operation of the router
First, make sure that the router is connected to the network and is active. Then check if other devices can see the network that the router creates. Use for these purposes, for example, a smartphone or another laptop.
If other gadgets also cannot detect the network, then most likely the Wi-Fi connection on the router is deactivated.
The first thing you can do in this case is simply reboot the router and check its operation again.
If no changes occur, then do the following (discussed using the example of a DSL router):
- connect to the router using the cable that came with it;
- go to any browser and enter address bar 192.168.0.1 or 192.168.1.1 and press Enter;
- in the authorization window that appears, enter the word admin in the “Username” and “Password” fields and click the “Login” button;
- go to the “Set up Wi-Fi” tab;
- Make sure the “Enable wireless connection” box is checked, then click “Next”;
- if necessary, enter connection settings (to find out the exact parameters, contact your provider);
- At the end, don’t forget to save your changes.
The laptop sees Wi-Fi, but does not connect
The situation is a little different when the laptop sees Wi-Fi, but does not connect to the network. Below are ways to resolve this issue.
Make sure you enter the correct password
Probably one of the most simple options that can happen in this situation is entering an incorrect password. Make sure the password you enter when trying to connect is correct.
If you have forgotten your password, you can easily recover it by following these steps:
- connect to the router’s web interface in the same way as described above, but this time select “Configure manually” from the menu;
- then go to the Wi-Fi tab;
- select the “Security Settings” tab;
- in the line “PSK encryption key” there will be your current password, which, by the way, can be changed here.
Check your MAC filter settings
A MAC filter is a special service that filters devices trying to connect to a wireless connection. Sometimes such a service can be the reason why a laptop sees Wi-Fi, but does not connect to the network. To solve the problem, you can try disabling the MAC filter.
Process to disable MAC filter for DSL router:
Check the laptop's Wi-Fi module
If everything is fine with the router and other devices can easily connect to it, then you need to deal with the laptop itself.
First of all, check that Wi-Fi module laptop is turned on. Depending on the laptop model, a certain combination of function keys, for example, Fn + F5, or a special switch located on the body of the gadget, may be responsible for activating the module.
Make sure your Wi-Fi adapter driver is working correctly
If the wireless module is active, but the laptop does not connect to Wi-Fi, then you should check the driver of the Wi-Fi adapter.
To do this, use the following instructions:
If there is an exclamation mark next to the module, this means that the driver or the device itself is not functioning correctly. Double-click on the adapter and check the error that appears in the window that appears.
The easiest way to solve this problem is to remove the current driver, reboot the system and install the driver again.
Adjust your wireless connection settings
If your laptop sees Wi-Fi but does not connect, and you have already tried the above methods to resolve the problem, then you should check your wireless connection settings.
Instructions:
After these manipulations, try connecting to the wireless network again.
37 387 Tags:A very common situation: a user tries to connect to Wi-Fi from his phone, but nothing works. After reading the information below, you will learn why this is happening and how to solve the problem.
Initial phone check
Manufacturers are actively working to improve the stability of mobile phones. operating systems, but periodically any program crashes. That is why it is recommended to start solving the problem by checking the functionality of the phone. For Android, iOS and Windows Phone ( Windows Mobile) the recommendations in this case are identical. Follow the sequence below.1. Restart your device and try connecting to Wi-Fi again.
2. Evaluate the number of connection signal strength indicators. If there are less than 3, try moving closer to the router or other source you are using wireless internet to improve connection quality.
3. Make sure Battery Saver mode is turned off. If necessary, connect the network adapter.
4. Turn off Bluetooth. Wireless connections may operate in the same range, which causes interference.
5. Turn off Airplane mode, if active.
6. Try to activate access to information about your location and connect to Wi-Fi - the legislation of some countries blocks connections via wireless networks when this option is inactive.
If the WiFi connection worked previously
If you have successfully used the currently problematic network in the past, remove this connection from your phone's memory. To do this, go to the list of networks, click on the problematic connection for a few seconds (until the context menu) and delete the connection.If all else fails, try connecting from your phone to any other available connection. Failure in this case will most likely indicate a breakdown of the radio module - only service center employees will help correct the situation.
Check if the connection is working. To do this, try connecting to it using any other device that has Wi-Fi functionality. If the connection does not work, change the router settings.
Important note! The procedure for entering the router settings varies depending on the manufacturer and model of the equipment. In most cases, to gain access you need to enter the address 192.168.0.0 or 192.168.0.1 into the address bar of your browser. The standard login and password are admin. If this doesn’t work, check the manufacturer’s instructions for the information relevant to your router.
First, try simply rebooting the router - quite often they freeze, which is why access to the Internet is blocked.
The further procedure is as follows.
First, you must ensure that the security key you entered is correct. Try entering the password to connect to the selected access point again, but more carefully, with the “Display symbols” (show password) option activated.
If you don't remember the password, check it in the router settings.
As an example, the order of interaction with D-Link router. In your case, everything will be almost the same; minor changes may only affect the interface, menu item names and other little things.
Once on the router settings page, do the following:
click the “Advanced settings” button;
in the Wi-Fi window, open the “Security Settings” link;
in the “PSK encryption key” line, look at the password and make sure that this is the combination you enter when trying to connect to Wi-Fi from your phone.
Secondly, make sure your router settings are correct - you need to check if DHCP technology is enabled. If it is turned off, the phone will not be able to obtain an IP address, which is why the connection will not work.
On the router settings page, click “Advanced settings” again and in the “Network” window, find the “LAN” category.
Enable DHCP if the function is disabled by changing the “Mode” line to the “Allow” state.
Save the changes, restart the router and try connecting to Wi-Fi from your phone.
If this does not help, there are 3 options left:
call the provider’s support service and find out whether the Internet works at all and whether any changes have been made to the connection settings;
submit your phone for repair;
have your Internet router repaired/replaced.
If our instructions did not help solve the problem, then write in the comments and we will definitely look into your problem.
Again I want to try to answer Daniel.
Daniil, I have “Multifunctional” installed wireless router N series" TP-LINK TL-WR842N.
I purchased and installed it when I was tired of “fiddling” with wires that were constantly getting in the way under my feet and not only for that reason.
Long before buying a router, I bought three “Wireless USB Network Adapters” TL-WN823N for my three desktop computers
and distributed WI-FI internet from your “main” (most powerful) computer, to which a high-speed Internet cable was connected. All traffic went through my computer, which entailed inconvenience - when I turned off my computer, I cut off Internet access to other family members and the load on my processor was noticeable.
By purchasing a router, I received a device that provides all my devices (personal devices, laptop, tablet and two smartphones) with equal and balanced speed access to the Internet.
Following the instructions in the "Guide to quick setup» router, I created my own wireless network, with my own password (not to be confused with the password for accessing a high-speed wired connection).
It is important here that the router connects to the Internet automatically, which is indicated by green lights. If the large light bulb (LED) glows green, it means the router has connected to the Internet and is ready to distribute the Internet; if it lights up yellow, then something is wrong with the connection to Internet provider via cable (possibly not configured correctly).
Connecting to the Wi-Fi network we created is the same for both a laptop and a phone - see the list of available ones wireless connections, select the network with the name that we entered when setting up the router, click “connect”. When you connect for the first time, the system will require you to enter a password - enter the password, again, the password that we “hammered” into the router during setup (but this is not the password for the high-speed connection, you can forget that password, the router will always remember it).
Now about what all the fuss is about. As I understand, you decided to connect your computer to the router using a wire, and other devices using Wi-Fi. I didn’t try it, but immediately hung the router in the far corner and haven’t touched it since. I don’t remember why I didn’t try the way you are trying to connect, or maybe I even tried, but I can assume that it won’t work just like that, “from a running start.” Recently I read articles on the Internet, looking for an answer to the question of how to expand the Wi-Fi coverage area. So - it's not that simple. It is necessary to organize several networks and hierarchical dependence of devices (the required number of routers).
From the description of the TP-LINK router it does not at all follow that those four yellow connectors are an analogue of a HUB, designed to connect several computers to the Internet as if they were part of a Wi-Fi network, and they are not repeaters or branchers of the wired Internet. It's still called a wireless router.....
I managed to find a description of the router on the Internet in Russian and with pictures:
img.mvideo.ru/ins/50041572.pdf
Perhaps you will be able to learn something and I would be grateful if you later share the solution you found (if you find it).
But I wouldn’t suffer for a long time and would buy USB adapter Wi-Fi….
“I can’t connect to my WiFi” - topics with a similar name appear on various computer forums almost every day. And this is not at all accidental, because problems with wireless connections occur quite often. What could be the problem and how to solve it in this or that situation?
Check your internet connection
Before taking any action, make sure that the cable transmits the Internet. To do this, connect your computer to the modem or router directly using a wire. There is always a possibility that the problem comes from the provider (for example, when carrying out technical work, they usually turn off network access for users for several hours).
Checking if all devices are connected
Before asking the experts “what should I do if I can’t connect to my WiFi,” make sure that your network equipment is in an active state. First, the Wi-Fi indicator on the router itself should be lit. If the network is not enabled, you should enter the IP number (192.168.1.1 or 192.168.0.1) into the browser and connect it. You should also make sure that the appropriate adapter is enabled on the computer or laptop itself. This can be done through the Network and Sharing Center. Access" Windows (go to the tab responsible for the adapter settings and find the one that supports wireless connections). On some models laptop wifi turns on by pressing a certain button. You can try restarting your computer and trying to turn on the adapter again. If this does not help, you will most likely need to. If even reinstalling the driver did not help, you may need to reinstall the operating system.
If the computer “sees” Wi-Fi, but gives an error when trying to connect
“I did everything above, but I still can’t connect to my WiFi.” If your computer displays information about available networks, but when you try to connect, an error message appears on the screen, the problem may be due to an incorrect mode of operation of the router. Let's go to its settings (you already know how to do this from the previous paragraph) and change the mode from standard to mixed (Mixed), B/G/N or B/G.
Network without Internet access
This is perhaps one of the most common problems why WiFi won’t connect. Windows 8, by the way, is much more susceptible to this than previous versions OS. This happens because the computer receives an incorrect IP address or DNS server address. First you need to find out what exactly is wrong. To do this, open the list of available networks, right-click on the one you want to connect to, and select “Status”. If an IP address was not received or an incorrect one was received, next to the “IPv4 connection” line there will be a message stating that there is no access to the network. You can check this by opening “Change adapter settings” in the Network and Sharing Center. Having found your wireless connection, right-click on it and open properties, and then look at the IPv4 protocol. If any addresses are specified in the settings, write them down on a separate sheet (they may still be needed), and then change the options so that the IP address and DNS server address are obtained automatically. Confirm the changes made and check your Internet access. If this does not help, restore the default addresses used by the router.
Problems associated with incorrect DNS server addresses also lead to the Internet not connecting via WiFi. As in the previous case, they are displayed in the wireless network status window. In this case, next to the “IPv4 connection” line you will see the inscription “Without Internet access”. This is corrected, again, in the protocol settings. Try setting up automatic retrieval of the necessary addresses or entering “8.8.8.8” in the preferred DNS server column and “77.88.8.8” in the alternative column (public addresses of Yandex and Google DNS servers).
We hope this article helped you, and the need to write to specialists with the question “why can’t connect to my WiFi” is no longer necessary for you!
