Connecting a laptop to a wireless, Wi-Fi, network does not always go smoothly. If you're having problems, check out step by step instructions that will help troubleshoot the problem. We recommend not to ignore this or that action, but to perform everything sequentially, as in the article.
Diagnosing the source of the problem
If your device, a laptop, fails to connect to the Wi-Fi network, the problem may be hidden in incorrect settings router. The first step is to find the source of the malfunction that leads to the connection error. This is what further “treatment” depends on.To determine the source, connect your iPad, smartphone, computer (any other device) to a Wi-Fi network. If the connection on any of the devices is successful, the conclusions are obvious - the problem lies in the laptop. And if you fail to connect via a wireless network, as in the first option, it means that the router is not configured properly. We will consider both cases separately. So, what to do if the problem is in the laptop?
Hardware enablement of the Wi-Fi module of the laptop
The diagnostics carried out earlier (see step one) revealed the following: if you were able to connect, for example, a tablet or smartphone to the wireless network, then everything is fine with Wi-Fi, and the problem lies in the laptop.To solve it, the first thing you need to do is check the status of the wireless adapter of the “problem” device. It may be disabled, and therefore the Wi-Fi network does not work on this device. The adapter is connected with a specific set of buttons and shows operation using a light indicator.
The indicator light is traditionally located on the front or side of the laptop. But there are some models of laptop computers that differ in the location of the indicator. For example, it can be located on the monitor (its body) or touchpad. And there is a third group of laptops. They have a light indicator, which shows whether the wireless network module is working or not, located on the power button (that is, built-in).
To connect the wireless network module, a specific key combination is required. Any combination begins with the Fn modifier key, to which one of the functional keys is added - F1-F12. If you look closely at the function keys, you will see a wireless, wi-fi, network icon.
Acer laptops differ from more modern models in that they turn on the wireless network module using a special two-position switch. If you have a laptop from this company, you will most likely find this switch on the side. In the screenshots below we showed how the Wi-Fi adapter is turned off or on on laptops from different manufacturers.
Acer: Fn+F3
Asus: Fn+F3
Dell: Fn + F2
Fujitsu: Fn+F5
Gigabyte: Fn + F2
HP:Fn+F12
If the wireless network module is working, connect via Wi-Fi network. Are there still problems? So, follow the third step.
Software enablement of laptop Wi-Fi module
The second step we tried to fix the problem was to hardware enable the wireless network adapter. Now we will try to do this programmatically. This means that our next actions will be performed in the OS itself, the software that is installed on our laptop computer.If you have Windows version 7 operating system, follow these steps::
Step one To enable the Wi-Fi module, go to the “Network and Sharing Center” section. shared access» (where the time is shown).
Step two On the left, click on “Change network module parameters”.
Step three Here you will see a list of connections. The indicator should be lit when connected via a wireless network; if not, the module is disabled. Click on it and turn it on.
If the icon lights up, the Wi-Fi adapter is turned on.
Act four Go to the taskbar (where the clock and other icons are). As you remember, in the second step the problem was that the wireless module was working fine, but there was no network to connect to, which means the router was not configured correctly. The picture shows 2 connection states in the task area of the desktop: the first - there are no available networks and the second - there are.
With the help of the third step you have enabled the Wi-Fi adapter, now you need to find your network and simply connect.
The module was successfully enabled using software methods, now try connecting to the Wi-Fi network. Is the problem still there? Follow the next fourth step.
Installing/reinstalling drivers for the Wi-Fi module
Now you need to check if the driver is on the system. In “My Computer”, click on “Properties”, and from there go to “Device Manager”.
A menu window will open. Here you need "Network Modules". You need to find the name of your wireless module. In this name you will see the word Adapter (if the operating system on the laptop is English language) or “Wireless network adapter” (if it is in Russian). For example, the name of the module will be: Qualcomm Wireless Network Adapter. Click on the name of the adapter and in “Properties” see how the device works. It should work fine.
Important information! If in “Network adapters” you do not find the name of the wireless module installed on the laptop, it means there are no drivers. Download them from disk or find them on the official website of the manufacturer.
Troubleshooting connection problems in the router
In the first step, if you remember, we recommended that you, if possible, find the exact reason why the wireless network on your laptop does not connect. Depending on this, we proposed methods to eliminate the problem.What to do if the problems lie in the router settings? We cannot consider each individual case, since both the routers and the devices installed on them software(firmware) sufficient quantity. Therefore, we will limit ourselves to only general tips that will hopefully help you solve the problem with connecting to a wireless, Wi-Fi, network.
- Place the router next to the computer.
- Check if the wireless network adapter is turned on (if the indicator light is on).
- Is the wireless network module turned on?
- Is the broadcast channel enabled in the Service Set Identifier?
- Check if your laptop's unique identifier (its MAC address) is on the blacklist.
After running the diagnostics operating system described in this article, you must solve the problem of connecting Wi-Fi on a laptop.
Very often there are cases when Wi-Fi on a laptop turns off on its own. Now we will figure out why the Internet disappears via Wi-Fi and how to solve this problem. If you came to this page, then you most likely already have this problem. We connect our laptop to Wi-Fi, the Internet works, but sometimes it disappears. There's one here important point: Wi-Fi does not turn off completely, but simply switches to the status “No Internet access” or “Limited” (and a yellow exclamation mark appears). Well, the Internet doesn't work. Although, there are times when the computer is completely disconnected from the wireless network. This problem is not uncommon on Windows 7, Windows 8, and Windows 10. So it doesn't matter what operating system is installed on your laptop.
As a rule, the Wi-Fi connection disappears periodically, or after waking up from sleep mode. There are times when the Internet stops working for a few seconds and then appears again. In any case, this creates a lot of inconvenience. You have to wait, reboot the laptop, downloading files, watching movies, etc. are interrupted.
Important point! We will look at solutions when the Internet turns off on only one laptop. That is, other devices that are connected to your router continue to work normally. If the Internet disappears on all devices, both via Wi-Fi and cable, then this is already a problem with the Wi-Fi router, or some kind of problem with the Internet provider.
If you have a problem only on one computer, then now we will try to solve it.
Why does the Wi-Fi connection on my laptop disappear?
The main reasons for losing the connection to the router:
- There is interference on the channel on which your Wi-Fi network operates. Or, weak signal wireless network.
- Shutdown Wi-F adapter to save energy (Wi-Fi disappears when waking from sleep mode)
- Unstable driver operation Wi-Fi adapter A.
- Problems with the router
I will show using Windows 7 as an example. If you have Windows 8.1 or Windows 10 and the Internet also disappears every 5 minutes (maybe more often or less often), then these tips will suit you. As for Windows 10, it is now full of problems with drivers. Therefore, if the connection in the “ten” is broken, I would first advise experimenting with the drivers of the wireless adapter and try to follow the recommendations from this article:.
Wi-Fi disconnects due to interference and weak signal
Our home wireless network operates on a specific channel. As a rule, there are many other neighboring networks within a radius that can cause interference. Interference may also come from other household appliances. And coupled with a not very stable wireless network signal, this can lead to a disconnection of the Internet on the laptop. A yellow exclamation mark "without internet access" may appear and work again after a while.
Also, disconnection may occur due to bad signal, when you move far from the router, and on the laptop, where the signal strength is displayed, one or two bars remain. In such cases, the connection may disappear altogether. If the Internet constantly breaks out in those rooms where the signal is weak Wi-Fi networks, then we need to strengthen the signal of our network so that the connection is more stable. I wrote about this in the article: .
As for problems with interference, here you need to experiment with the channel on which your network operates. You can try with special program find the freest channel and set it in the router settings. Or, simply set some kind of static channel in the router settings. I described in detail how to do this in the instructions: If you already have a static channel, then set it to Auto.
This is what changing the channel looks like on a Tp-Link router:
Please note under what conditions the Internet connection occurs. This could be, for example, moving around the house, or only in certain places (rooms). Then it will be easier to find the cause and eliminate it.
What to do if the Internet disappears after waking up from sleep mode
This happens because while asleep Windows mode disables the Wi-Fi adapter to save energy. And when you exit sleep mode, the adapter can no longer work normally, and you need to restart the laptop. Also, problems are often observed when the laptop is running on battery power. We need to disable the wireless adapter from turning off, and set maximum performance when running on battery power and mains power.
Let's set up the power supply first. Press the keyboard shortcut Win+R. Copy the command control powercfg.cpl in the "Open" line and click on the button Ok.
A window with power plans will appear. I advise you to choose Balanced. Next, click next to this plan on the link Setting up a power plan.
Next we open Change advanced power settings. Looking for a section Wireless adapter settings, open it and install Maximum performance when operating from mains and battery. Click Apply And Ok.
We prohibit disabling Wi-F adapter to save energy
Disabling the adapter will not save us a lot of electricity, but problems with its operation may appear. Therefore, you need to prevent Windows from turning off the adapter.
Click Win+R, copy the command mmc devmgmt.msc and press Ok.
Device Manager will open. Find and open the tab Network adapters. Then, click right click mouse to Wi-Fi adapter (its name should contain the words "Wi-Fi", "Wireless") and select Properties.
Go to the tab Power management, and uncheck the box Allow this device to turn off to save power. Click Ok.
We reboot the laptop and check how the Internet will work via Wi-Fi.
Internet may disappear due to driver problems
If the Wi-Fi adapter driver is outdated, or the wrong driver is installed, then a variety of operational problems may appear. wireless connection. Open Device Manager like I showed above (press Win+R and execute the command mmc devmgmt.msc). Open the tab Network adapters. Find wireless adapter (the name will include "Wi-Fi", 802.11n, or "Wireless"). There may be a yellow exclamation mark next to the adapter. This means that the device is not working correctly.
Even if there is no warning icon, try updating the driver for this adapter. Perhaps this will solve the problem with Wi-Fi disconnecting. Just don't update through Device Manager. (the system will say that the update is not needed), and download the driver from the official website of your laptop manufacturer. Required for your model and operating system. Download and install the driver. I wrote in more detail about driver installation in the article.
Also, you can try to choose one with already installed versions driver, remove the driver, or roll back it. I described all these actions in more detail using Windows 10 as an example in a separate article:.
What to do if the Internet periodically disappears on all devices?
If your Internet connection disappears simultaneously on all connected devices, then the problem is already in the router. I wrote about this at the beginning of the article. On computers, the connection status becomes "no internet access".
And on mobile devices (smartphones, tablets), the Internet simply stops working. And after such failures, you always need to reboot the router, only after that the Internet starts working again. Moreover, such interruptions usually happen at moments when the router is under heavy load: we are downloading something (especially from torrents), watch online videos, play Online Games, we connect some other devices to Wi-Fi, etc. And basically, this problem occurs on inexpensive routers.
This is understandable, they simply cannot withstand the load and “fall”. Only a reboot saves. My friend has exactly the same (which is from the Kyivstar provider). After connecting the smartphone and laptop, everything works well. As soon as you turn on watching online video, after a while the Internet disappears.
What can be done:
- Connect the Internet without a router, directly to the computer, and check the operation. To eliminate interruptions on the provider's side.
- Update the router firmware, this often helps. We have instructions on our website for all popular router manufacturers.
- Disable torrent clients on devices (if there are any). They create a load due to which the Internet disappears.
- If you have Internet via a 3G/4G USB modem that is connected to a router, then such interruptions most likely occur on the provider’s side.
- Well, buying a more powerful router.
It seems like I didn't miss anything. Write in the comments how you managed to get rid of this problem.
Wireless technologies, including WI-FI, have long and deeply entered our lives. It is difficult to imagine a modern home in which people do not use several mobile devices connected to the same access point. In this state of affairs, situations often arise when Wi-Fi turns off “in reality” interesting place", which causes a certain discomfort. The information presented in this article will help solve this problem.
The wireless connection may be interrupted due to various reasons and under different conditions. Most often, Wi-Fi disappears when the laptop wakes from sleep mode. There are situations where communication is interrupted during work, and, in most cases, a reboot of the laptop or router is required to restore the connection.
There are several reasons why such failures occur:
- Obstacles in the signal path or significant distance from the access point.
- Possible interference in the router channel that includes the home wireless network.
- Incorrect power plan settings (in the case of sleep mode).
- Problems with the WI-FI router.
Reason 1: Remote access point and obstacles
It was not in vain that we started with this reason, since it is precisely this that often leads to the device being disconnected from the network. Walls, especially solid ones, act as obstacles in an apartment. If only two divisions (or even one) are displayed on the signal scale, this is our case. Under such conditions, temporary disconnects may occur with all the consequences - download interruptions, video stops, and others. The same behavior can be observed when moving away from the router by long distance.
In this situation, you can do the following:
- If possible, switch the network to 802.11n in the router settings. This will increase the coverage range as well as the data transfer speed. The problem is that not all devices can operate in this mode.
- Purchase a device that can function as a repeater (repeater or simply “extender” of a WI-FI signal) and place it in an area of poor coverage.
- Move closer to the router or replace it with a more powerful model.
Reason 2: Interference
Interference on the channel may be caused by neighboring wireless networks and some electrical appliances. If the signal from the router is unstable, they often lead to connection interruptions. There are two possible solutions:
Reason 3: Energy Saving Settings
If you have powerful router, all settings are made correctly, the signal is stable, but the laptop loses the network when exiting sleep mode, then the problem lies in the plan settings Windows power supply. The system simply turns off the adapter during sleep and forgets to turn it back on. To eliminate this problem, you need to perform a number of actions.
- Let's go to "Control Panel". This can be done by calling the menu "Run" keyboard shortcut Win+R and entering the command
- Next, we set the elements to be displayed in the form of small icons and select the appropriate applet.
- Then follow the link "Setting up a power plan" opposite the activated mode.
- Here we need a link with a name "Change advanced power settings".
- In the window that opens, open one by one "Wireless adapter settings" And "Power Saving Mode". Select a value from the drop-down list "Maximum performance".
- Additionally, you need to completely prohibit the system from turning off the adapter in order to avoid additional problems. This is done in "Device Manager".
- Select our device in the branch "Network adapters" and move on to its properties.
- Next, on the power management tab, uncheck the box next to the item that allows you to turn off the device to save energy, and click OK.
- After the manipulations have been completed, the laptop should be rebooted.
These settings allow you to keep the wireless adapter always on. Don't worry, it consumes very little electricity.
Reason 4: Problems with the router
Such problems are quite easy to identify: communication is lost on all devices at once and only rebooting the router helps. This occurs due to exceeding the maximum load on it. There are two options: either reduce the load or purchase a more powerful device.
The same symptoms can be observed in cases where the provider forcibly resets the connection when there is increased network load, especially if 3G or 4G is used ( Mobile Internet). It’s difficult to advise anything here, other than to minimize the operation of torrents, since they are the ones that create the maximum traffic.
Conclusion
As you can see, problems with turning off WI-FI on a laptop are not serious. It is enough to complete necessary settings. If your network has a lot of traffic consumers, or a large number of premises, you need to think about buying a repeater or a more powerful router.
I often get asked questions about the problem when Wi-Fi disappears on a laptop or computer. It doesn’t just disconnect from the network, but the Wi-Fi adapter and the connection itself completely disappear. In Windows, everything related to Wi-Fi disappears. No wireless adapter in network connections. There is no "Wi-Fi" button, no icon in the notification panel and no section in the settings (if we are talking about Windows 10). In the device manager there is also no WLAN (Wireless) adapter, which is responsible for connecting to wireless networks. Well, accordingly, the computer does not see the Wi-Fi network, and there is no way to connect to it.
In most cases, the problem appears suddenly. Everything worked, turned off the laptop, turned it on and there was no Wi-Fi on the laptop at all. IN in some cases such a problem may appear after Windows updates, or drivers. Or maybe after installing some program, or changing settings. From my own experience, I can say that it is not uncommon for Wi-Fi to disappear after cleaning the laptop from dust or repairing it.
Two important points:
- It happens that the laptop simply does not see a specific network, or all networks. In this case, the adapter is in the device manager, there are settings related to the wireless network, etc. This is a slightly different problem, which I wrote about in the article and.
- It may also be that he himself. In this case, the network is not available on all devices.
To find a solution, you must first understand the cause. Why did it happen that the laptop suddenly stopped seeing Wi-Fi networks and there are no settings related to this at all.
- You need to think and remember what you did before the problem appeared. Perhaps the solution will come on its own.
- Restart your laptop. If you have Windows 10, you need to reboot. Not Off/On.
- If you have a PC with an external Wi-Fi adapter, check if it is connected. Try connecting to a different USB port. Notice whether the light on the adapter is blinking.
- If Wi-Fi disappeared after cleaning or repairing the laptop, then most likely it was simply not connected (poorly connected, damaged) the Wi-Fi module itself in the laptop. If you did this yourself, then disassemble the laptop and check the connection Wi-Fi module and antennas.
The Wi-Fi adapter has disappeared from Device Manager
If network cable is not connected, the icon on the notification panel will look like this:
If you go to adapter management, then most likely there will only be Ethernet (or "Connect via local network" in Windows 7). Well, maybe Bluetooth. And we need a “Wireless Network” or “Wireless Network Connection” adapter.
In Device Manager, open the "Network Adapters" tab. Most likely, you will not find an adapter there whose name includes “Wireless”, “WLAN”, “Wi-Fi”. And that's exactly what we need.
See if there is an unknown device in Device Manager. Or devices with yellow exclamation mark. If there is, then it is quite possible that this is our wireless adapter, which simply has problems with the drivers.
Pay special attention to the "Other devices" section. Is there something like "Network Controller" there?
If it is, then you just need to install the driver.
How to solve the problem and return the Wi-Fi adapter?
Unfortunately, as I wrote above in the article, in most cases this is a hardware problem. That is, a breakdown of the module itself. And programmatically (some kind of settings) it cannot be solved. You need to change the module itself, or connect an external adapter via USB. If it's a laptop.
All solutions boil down to reinstalling the Wi-Fi driver. Perhaps if the adapter itself is working, this will help. Well, you can also reinstall Windows. There may be something in the system, but it is very unlikely.
And so, let's return to the driver. You just need to go to the laptop manufacturer’s website, use a search to find your model and download the driver for WLAN (Wi-Fi). Then run its installation. If at the beginning of the driver installation an error appears that the device was not detected in the system, or something like that, then I am almost sure that this is a hardware failure.
Detailed instructions for installing drivers:
- And separate installation instructions and .
If you have tried everything, and in the device manager there are no adapters associated with wireless networks, including unknown devices, then you will have to take the laptop for repair, or connect USB WiFi adapter. There are small ones that are great for laptops.
Wi-Fi on the laptop has disappeared and there is a red cross everywhere - this is the most common error. Although problems with wi-fi connection Any user of modern devices has ever experienced access to the Internet. Unstable Internet (or even its complete absence) is usually very annoying; you want the problem to be solved as soon as possible, but it cannot be solved on its own - you need to diagnose the problem and make efforts to solve it. Just today we will look at the most common wifi problems connections to the Internet and ways to solve them.
Why wifi disappears - reasons
Reasons that could potentially cause the lack of stable wifi connections(or connection in general) is incredibly large, this is a banal distance over an excessively long distance, and the presence of any radio interference in the coverage area of the access point, and the presence of all kinds of shielding elements between the router and you. However, most often the network disappears due to software errors and hardware malfunctions.
Diagnosis of the problem
If the Internet via wifi is lost, and there are no obvious signs of a hardware malfunction (a broken router antenna, for example), and getting close to the access point to a distance of 3-5 meters did not help, you should start looking for software errors. The mechanism for detecting them is individual for each specific OS and gadget. And yet, in the case of the most popular devices, such as laptops with Windows, smartphones running Android and iPhone, there are some universal recommendations that with almost one hundred percent probability will help to detect the software cause of the lack of signal.
If your gadget is running a less popular OS, for example, Symbian, Windows Mobile, or even some kind of “homemade Chinese OS”, it is impractical to carry out software diagnostics, since the built-in mechanisms for this in such OSs, as a rule, are absent, and flashing the firmware will take much less time than poking around in the software core.
What to do if wifi disappears on a Windows laptop
The reasons for the loss of wifi signal on a laptop can be divided into three categories:
If, when you press the corresponding key on the laptop, the wifi module operation indicator (the light next to which wifi is written or the corresponding icon is drawn) does not light up, then the problem is in the device itself. Check if the corresponding option is enabled in the BIOS. To do this, restart the laptop and press the corresponding key in the first 3-5 seconds of booting. As a rule, this is F2, F8 or F12. However, the initiation key BIOS boot there may be another - carefully read the notification that appears when you turn it on (usually desired button written below right). It is worth noting that in your BIOS version there may not be an option turn on wifi module, so it is first recommended to read the user documentation or enter the combination of ““name of your laptop” wifi bios” into a search engine.
Wi-Fi disappeared in windows
If the wifi module and router operation indicators are lit but there is no signal, you should check whether wifi is enabled in Windows itself. Right-click the corresponding taskbar icon (the bar at the bottom or top of the screen), then click: “Network and Sharing Center” => “Change adapter settings” => Find the monitor icon with the wifi signal strength scale => “Enable”.
Also instead of pressing right key Click on the icon on the taskbar and click “start” => “control panel”.
Often the reason why wifi on a laptop disappears is faulty drivers. Right-click the “computer” shortcut, select “properties” => “device manager” and find “ network adapters" Make sure the adapter is turned on. If there is a yellow triangle next to it, select “update drivers”.
Reason unstable work wifi may be high load on the router. Check and disable the most active users!
If the laptop sees other networks, but cannot connect to the one you are interested in, the problem is in the router settings. To diagnose it, you need to connect to the router using a cable or other device and dial address bar browser debugging address: “192.168.0.0”. In the window that appears, enter: “admin/admin”. Next, you should check whether signal transmission via wifi is turned on, and whether your device is on the “black list” of the MAC filter. You should also make sure that the router allows the simultaneous connection of multiple devices.
If you cannot connect to the router even through a cable, you should press the “reset” button on the router and wait 10-15 seconds.
If none of the above helps, try calling your Internet provider and ask if they receive feedback from your router (when it is turned on and working). If not, then most likely your router’s hardware has failed.
Wi-Fi on my laptop turns off constantly or periodically, what should I do?
If the signal on the laptop appears and disappears, no matter what access point you are connected to, most likely the problem is in the system power plan settings. To fix this problem, select the " maximum performance", but please note that this will affect battery life. In addition, disable automatic hibernation - very often, after waking up from sleep mode, the wifi adapter de facto remains turned off until the next reboot.
My iPhone loses wifi, what should I do?
First, make sure that the problem is in the iPhone, and not in the router - often, users mistakenly believe that wifi is not working on the iPhone, although the reason is the access point. If your gadget sees other networks, the iPhone is working. Secondly, make sure you have current version iOS.
If iOS update did not help, click: “Settings” => “General” => “Reset” => “Reset network settings”.
If this doesn’t help, the iPhone is faulty.
If the gadget does not connect to any network at all, either reflashing it or going to a technician will help. If it connects to some networks but not to others, you should enable the bgn broadcast mode on the desired access point and try to set a static signal broadcast channel instead of the Auto mode. This can be done through the router settings menu (the address described above is 192.168.0.0). It is also worth noting that not all android devices support pairing with wifi, relayed through a laptop in forwarding mode (when the laptop acts as a router).
The Internet via wifi has disappeared, but there is a wifi network
If the device is connected to an access point, but there is no Internet, check the cord going to the router and contact your provider. If the problem is only on some specific device, try clearing your cache or using a different browser. You should also make sure that the device (not the memory card!) has at least 10% memory.
What to do if the wifi icon disappears
If the icon itself disappears, you should make sure that wifi mode is turned on. If the option to turn on wifi is missing, or the icon does not appear, you will have to reflash your smartphone or update your laptop drivers.
So, the article discussed all the most common problems with wi-fi access on the Internet, and ways to solve them were also proposed. If you read this article, have faithfully followed all the recommendations given, but your wi-fi still does not work - feel free to take your device to service center, since you (most likely) will not be able to fix the problem at home.
