Using the keyboard shortcut
Sometimes manufacturers refuse to provide space for a separate button responsible for WI-FI operation. Then its task is taken over by a combination of function keys. Usually, this is “FnF2” (see Figure 3). The first one is located near the left “Ctrl”, the second. above the numeric zone of the keyboard (in the row of the so-called function keys “F”).
- F2 does this role on not all laptops (this is a basic setting that can be changed by user settings);
- Also, if you’ve recently reinstalled Windows but haven’t yet taken care of installing all the basic device drivers, the function keys may not work.
Through the operating system (for example, Windows 7)
To do this, go to the “Network and Sharing Center” (for example, from the control panel). Then select “Change adapter settings” (menu item in the left panel). A list of all available connections that your laptop sees will open. Among them there should be a “wireless network” (if it is absent, skip this chapter and go to the next one, where the process of installing drivers is described in detail). The network icon can be gray (Disabled) and blue (Active). If you see a gray icon, click on it with the mouse (right click), and then select “Enable” (see Figure 4).
We have covered the main reasons for the lack of WI-FI connection on a laptop. There is only one caveat left:
If you’ve recently reinstalled Windows, but haven’t bothered to download drivers from the laptop manufacturer’s official website, many of its features may not work. The work of the WI-FI module will not be an exception. And, even if there are no comments in the “Device Manager” opposite the adapter, its correct operation is not guaranteed. Therefore, go to the official site and grab the drivers for your laptop. Quite often, this can be the only correct solution to the connection problem.
Now that we have made sure that the computer has a workable WI-FI module, go directly to the next two chapters of the article.
The network is detected, but the laptop does not connect to it
In most cases, this behavior of a laptop is due to the lack of necessary drivers for WI-FI. This mainly happens as a result of an incorrect completion of the reinstallation of Windows, when not all hardware “receives” its software.
And do not rush to consult the “Device Manager”. Often, he does not see even the slightest inferiority of the installed software or any malfunction. Therefore, in order to eliminate this problem, you should take care of the availability of current drivers from the WI-FI module. You can get them for free from the manufacturer’s official website, where they are always available.
Incorrect wireless settings
These settings could “fly off” due to an incorrect exit from Windows, or when creating a connection, they were simply forgotten.
Go to “Change adapter settings” (this item is located in the “Network and Sharing Center”, and the last one is in the control panel). Then find the wireless connection among the available connections and right-click on it. In the expanded list, select the bottom item “Properties” (see Figure 9).
Here select “Internet Protocol Version 4”, then go to its “Properties” (see Figure 10)
In the next window, you must set the automatic IP selection by placing black circles opposite the corresponding items (see Figure 11)
In most cases, this should fix the problem (especially if the addresses were manually entered). If, after doing all of the above, the laptop does not see the network as it should, we recommend contacting specialists (best from the provider).
If the router is to blame
Try to connect to the network using another device (tablet, mobile phone). If they can’t make contact with the router, either he or the provider’s fault is to blame. To discard the latter option, call your service provider and find out how things are going on your line. If everything is in order, we continue to “interrogate” the router. You need to go to its settings (you can use the web interface, the entrance to which was described in detail in the corresponding article) and find out if everything is in order there.
You can also call specialists, but often their arrival takes longer than self-configuration.
Where to see which WI-FI driver is currently installed
Regardless of the version of Windows, hold down the Win and R keys at the same time, then (in the window that opens) type devmgmt.msc and press Enter. This will launch the Device Manager (see Figure 5).
If this is your first time here, you may find that all devices are categorized into groups. The module of interest to us, with the help of which the laptop connects to WI-FI, will be in the “Network adapters”, where we go. Then we find it and right-click, then left-click on the item “Properties”.
In the next window, find the “Driver” tab and go to it. Look at the lines “Driver Provider” and its “Development Date” (see Figure 6).
And if the supplier is not “native” for the laptop (does not coincide with the name of the laptop brand), and the date is outdated by several years. run to the official website of the manufacturer. There, as mentioned above, you can easily find the current version of the drivers and download it.
After successfully installing the driver, you may need to start the wireless network. All the nuances of performing the driver update procedure were described in the first chapter.
The network is connected, but the sites are still unavailable
In this case, instead of the normal network icon on the taskbar, you may find this:
All the reasons why the user sees this icon can be divided into 3 groups:
- Malfunction or incorrect router settings;
- Incorrect settings in the laptop, or its hardware malfunction (which happens much less often), due to which it does not connect;
- Problems on the side of the provider, who temporarily stopped supplying the signal in full (for example, due to equipment repair on the line).
First, let’s try to find out why the network has limited access in your case. In other words, who to suspect of the problem: a router or a laptop?
Why do problems arise?
Mostly, failures while connecting the device to a Wi-Fi network occur due to incorrect settings of the wireless router. In this case, the laptop or tablet does not recognize the Internet connection at all. If this happened at home, you must sequentially perform a series of actions described below:
- First, you need to reboot both the router and the device that you plan to connect to the Wi-Fi network. The router can be turned off for a couple of seconds and then turned on again.
- The next step is to go to the device in the “Settings” menu, and then select the subtitle “Networks”. Next, you need to open “Wi-Fi” and see if your Wi-Fi device sees an access point.
- After following the above two steps, you will most likely be prompted for a password from the network. You must enter the password that you set earlier when setting up the Wi-Fi network, or clarify the password from people who may know it, after entering the password you will connect to Wi-Fi.
- If everything goes unchanged, you need to restart the module again, that is, turn off and then turn on the Wi-Fi router.
- Sometimes situations may arise when it is imperative to make adjustments to the router settings. For example, the device may require setting the communication channel, frequency, network mode. All this is necessary in order for the router and the portable device to detect each other and work correctly.
If, when a portable device is connected to a Wi-Fi network, a pop-up window appears with the message “Saved, WPA-WPA2 security”, it means that the encryption on the router is incorrectly configured or the password for the Wi-Fi coverage was entered incorrectly. To fix everything, you need to follow these instructions:
- Check if the password is entered correctly by opening “Connection” and clicking “Change”. Next, you need to select the function of displaying the password and enter it again.
- If the password is entered correctly, but there is still no access, then the router settings are problematic.
Why Wi-Fi won’t connect?
Wi-Fi is the next generation of wireless technology. Only a little time, and this method of connection to the Internet is used by millions of users around the world. Wi-Fi connectivity makes it possible to connect compatible devices that are up to fifty meters from the access point. In this case, the data exchange rate is about 150 mb / s. However, this is not all. Thanks to the latest advances in this area, speeds can reach several gigabits.
Every modern laptop, tablet or phone has a Wi-Fi radio module to its credit. Thanks to this, there is a significant saving in expensive traffic of mobile operators, and the radio module also opens access to high-quality multimedia content, while nothing needs to be downloaded to the device. All you need is to set up a Wi-Fi connection on a portable device, set a security password and then save it to open up broad Internet access. However, sometimes not everything goes as smoothly as it seems.
Sometimes Wi-Fi won’t connect. Why? There are a number of reasons for this, the main of which we will now discuss.
If the settings are incorrect, you must:
- Carefully study the instructions supplied with the portable device used. It is especially important to know which network mode and type of information encryption is supported by your laptop, phone or tablet. WPA, WPA2 or WEP type can be used.
- Next, you need to go to the “Settings” of the router. To do this, you must enter the address 192.168.1.1 into the address bar of your browser, and then press the enter button. After that, you must enter the username and password attached to the administrator. Most often, the value admin is used under the username and password.
- The next step is to enter the menu item where the wireless network settings are directly set. You can safely experiment with them until the desired result is achieved. First, you can set the standard mode supported by the device. Most likely, this will be 11b mode, which has a low range. It is also required to indicate your country where the router is located, in the “Channel width” column it is necessary to set the frequency to twenty megahertz or select the automatic mode. Then it is necessary to save all the installed parameters of the router and at the end to reboot it.
So now your laptop, tablet or smartphone should connect to Wi-Fi. In this case, the initial connection of the device with the router will be broken, you need to reconnect. As for encryption issues, in these cases it is also necessary to proceed step by step:
- You need to go to the “Settings” of the router, select the item “Network Security”. the sub-item “WEP”, “WPA / WPA2”, and then enter a password that will help the router to recognize the user. You will understand which item to choose from the error message, or you can experiment yourself.
- Next, you need to save the settings using the corresponding function, and then reboot the router.
These are, perhaps, all the main actions that you can do at this stage. In other cases, it is better to contact a specialist for a more accurate setting.
Airplane mode activated
Disconnection of the wireless network can also occur due to the fact that the “Airplane” mode is activated on the laptop. In this case, the network connection icon in the tray changes to the image of an airplane. To deactivate this mode, you need to click on the airplane icon and then click on the corresponding icon to make it inactive. Many laptop models have a dedicated key to enable / disable Airplane mode, which is indicated by the same icon. It is usually paired with the F2 key. Thus, in order to deactivate the mode, you must use the keyboard shortcut Fn F2.
Problems with the Wi-Fi adapter driver
The presence of an established Wi-Fi connection is indicated by the corresponding icon in the tray. When everything is in order with the network, it usually looks like this: If there is no connection, another icon appears: The first thing to do in this situation is to check if the wireless adapter driver is installed. To do this, you should:
Open Device Manager. This procedure is almost the same in all Windows versions.
Read more: How to open “Device Manager” in Windows 7
If the adapter we need is not in the list of devices or is installed with errors, as evidenced by exclamation mark marks on the device name, then it needs to be installed or reinstalled. At the same time, it is strongly recommended to use the software from the manufacturer of this laptop model, which can be obtained on the official website, or that was supplied with the computer.
Problems with router settings
Broken router settings can also be the reason that the laptop does not connect to Wi-Fi. First of all, you should think about this if the computer does not see the network at all with a correctly installed adapter driver. Due to the fact that there are many different models of routers from different manufacturers using different firmware, it is very difficult to give step-by-step instructions in the article on how to troubleshoot problems with them. But there are still a few general points that can make this task easier:
- All modern routers have a web interface where you can configure their parameters;
- By default, the IP address of the vast majority of these devices is set to 192.168.1.1. To get into the web interface of the router, just enter this address in the browser line;
- To enter the web interface by default, manufacturers usually use the login “admin” and the password “admin”.
If you cannot connect to the router settings page with these parameters, refer to the technical documentation of your device.
The contents of the router interface can look completely different. Therefore, in order to change its settings, you need to be clearly sure that you understand what you are doing. If there is no such confidence, it is better to consult a specialist.
So, what can be the problems in the settings of the router, because of which the laptop cannot connect to Wi-Fi??
Wireless connection prohibited
Such a problem can happen with a home router, where the connection to the provider is carried out using a wired network and at the same time it is possible to create a wireless access point through which a laptop, tablet or smartphone can be connected to the Internet. Let’s see how it is configured using the example of the HUAWEI HG532e router.
In order to check if the Wi-Fi mode is enabled on the router, you need to do the following:
- Connect to the web interface of the router via a wired network.
- Find in the parameters the section responsible for configuring the wireless network. Most often it is referred to as WLAN.
- Check if there is a function for disabling the wireless connection and if it is disabled, enable it by ticking the checkbox.
On a number of router models, you can enable / disable the wireless network by pressing a special button on the case. But still, changing the setting via the web interface is safer.
The network connection may also be lost when the adapter is simply disconnected. Let’s consider a solution to this problem using the example of Windows 10.
You can determine that the device is disabled through the same device manager. Disabled devices are indicated by a downward-pointing arrow on the icon. To use the adapter, just use the RMB to open the context menu and select the “Enable device” item there.
In addition to Device Manager, you can enable or disable the wireless network adapter through the Windows Network and Sharing Center. To do this, you must:
- Click on the network connection icon and follow the corresponding link.
- In a new window go to the section “Configuring adapter parameters”.
- After choosing the desired connection, activate it using the PCM.
Problems with laptop settings
Most often, the reason for the lack of network connection lies in the incorrect settings of the laptop. There are a lot of settings that affect the operation of the network, so there are several reasons due to which it may not function.
Connection filtering enabled
This function is present in routers in order to maximize the protection of users from unauthorized connections to their home network. In the HUAWEI router, its setting is also in the WLAN section, but on a separate tab. In this example, you can see that the filtering mode is enabled and access to the network is allowed to a single device whose MAC address is specified in the Whitelist. Accordingly, in order to solve the problem with the connection, you need to either disable the filtering mode by unchecking the “Enable” checkbox, or add the MAC address of your laptop’s wireless network adapter to the list of allowed devices.
The second way is easier
If you got lost on the manufacturer’s website and could not find a working driver, then you can download “DriverPack Offline Network” from the site. https://drp.su/ru/foradmin. But be careful before installing, this package also has the ability to install any garbage. Therefore, after installing the driver, go to “Programs and Features” and remove all associated programs installed. Do not be lazy to do this, as these programs significantly slow down the work of your computer.
No network connectivity after upgrade
As an existing malfunction, the following can be noted. Sometimes users change passwords or encryption types, after which they do not know what to do and how to restore the connection to the hidden network, because before that everything happened automatically. To solve this problem, you should delete the existing network on the gadget and reconnect to it.
Removal is quite simple, you need to go to the “Network and Sharing Center” by clicking on the network icon on the right, in the lower corner, and then select the “Wireless Networks Management” tab.
Having selected the network, click with the mouse and press “delete”. After the removal procedure, we reconnect it and enter a different password if it has been changed.
Why won’t my laptop connect to my home Wi-Fi network? On some laptops, the power button for the internal transmitter is on the side. Some models include Wi-Fi hotkeys. Maybe you accidentally pressed this button and just turned off the module itself. Perhaps it turned off by itself, going into standby mode, or such a setting is in power saving mode. Then you will see a red cross on the connection. The instruction is suitable for all versions of the Windows operating system.
- Run the command execution program by pressing WinR.
- Turn on the wireless module. if it is grayed out.
Also look for the Wi-Fi power button on your laptop. It can be as a combination with the “Fn” key, then the second button will be in the “F” row. Often this is FnF2, F3, etc. But it can be a separate switch or a button.
Why the laptop won’t connect to the Wi-Fi of the phone
There can be several problems here. One is on the side of the router, the other on the side of a laptop or computer with a Wi-Fi module. Of course, this is too simple to explain, but in the article I will analyze all the problems with both the laptop and the router.
NOTE! If there is a Wi-Fi connection, but the laptop does not connect to the World Wide Web (yellow triangle on the connection), then the problem is different and I have already described it in another article. Check the instructions here.
Let’s reboot our router first. If he abruptly stops connecting to WI-FI or does it for a suspiciously long time, then this may indicate overheating of the device. Our task is to find a small ON / OFF button and turn off our transmitter.
But turn it on after 5 minutes. let it cool down. If after turning on the wireless network did not work, then proceed to the instructions below.
- Right-click on the connection and then select “Network and Sharing Center”.
- “Management of wireless networks”.
- Remove home network.
- Then try to connect to it again.
Lack of network connectivity due to malfunctions on the laptop
The first and easiest thing to do is to simultaneously use the fn key in the lower left corner and connect to Wi-Fi on the computer. The latter can be located on the side, but more often on one of the buttons of group F, it is easy to find it by the antenna icon.
If after pressing the keyboard shortcut several times, the device does not want to connect, we are looking for a problem elsewhere. Sometimes an access error can occur due to the installed antivirus program, which blocks all suspicious connections that seem to it. In this case, you need to temporarily disable the antivirus and check the signal, if necessary, reboot.
An interesting video on the Wai-Fai malfunction on a laptop:
Enabling Wi-Fi via Network Sharing Center
To configure Wi-Fi using the control center, you need to click on the connection icon in the lower right corner. In the pop-up window, the inscription “Network and Sharing Center” will appear at the bottom.
Now, in the upper left corner, click “change adapter parameters”.
If there is no connection, then this needs to be corrected, then a yellow asterisk will appear on the network icon, which indicates the available connections that have appeared and the normal functioning of the adapter.
If the wireless adapter is turned on, but the problem is still not resolved, the laptop does not see Wi-Fi when the adapter is turned on, the icon is still marked with a cross, we are looking for another reason.
Check your MAC filter settings
MAC Filter is a special service that filters out devices that try to connect to a wireless connection. Sometimes such a service can be the reason why the laptop sees Wi-Fi, but does not connect to the network. To solve the problem, you can try to disable the MAC filter.
Process for disabling the MAC filter for a DSL router:
- as in the previous example, go to the “Wi-Fi” tab, but already select the “MAC filter”;
- turn off the filter and click the “Change” button.
We solve the problem when the laptop sees Wi-Fi, but does not connect
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.
Make sure the 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 instruction:
- start the device manager (the fastest way is to press the WinR keys and then enter the mmc devmgmt.msc command);
- in the branch called “Network adapters” select the wireless network adapter.
If there is an exclamation mark next to the module, it means that the driver or the device itself is not functioning correctly. Double click on the adapter and in the window that appears, check out the error that occurred.
The easiest way that can solve a similar problem is to uninstall the current driver, reboot the system and install the driver again.
Make sure to enter the correct password
Probably one of the simplest options that can occur in this situation is entering an incorrect password. Make sure the password you enter when trying to connect is correct.
In case you have forgotten your password, you can easily recover it, to do this, do the following:
- connect to the web interface of the router as described above, but this time select “Configure manually” from the menu;
- then go to the Wi-Fi tab;
- select the “Security Settings” tab;
- the line “PSK encryption key” will contain your current password, which, by the way, can be changed here.
Why the laptop won’t connect to Wi-Fi
The most common problems with connecting to a wireless network occur in the following cases:
- the router settings are incorrectly set (knocked down);
- the Wi-Fi adapter on the laptop is deactivated;
- the driver for the wireless adapter is missing or damaged;
- the laptop’s Wi-Fi module is out of order;
- operating system crashes.
Check the Wi-Fi module of the laptop
If everything is in order 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 the laptop’s Wi-Fi module is turned on. Depending on the laptop model, a certain combination of function keys may be responsible for activating the module, for example, FnF5 or a special switch located on the gadget case.
How To Fix WiFi Not Working Issue On Windows 10
Laptop sees Wi-Fi but won’t connect
The situation is a little different in the case when the laptop sees Wi-Fi, but does not connect to the network. Below are the solutions to this problem.
Correct the wireless settings
If your laptop sees Wi-Fi, but does not connect, and you have already tried the above solutions to the problem, then you should check the wireless connection settings.
- go to the Network and Sharing Center on your laptop;
- find a wireless connection and click on it with the left mouse button;
- in the window that opens, click on the “Properties” button;
- select “IP version 4 (TCP / IPv4)” and click the “Properties” button;
- check the boxes next to Obtain an IP address automatically and Obtain DNS server address automatically, and then click OK.
After these manipulations, try to connect to the wireless network again.
The phone does not connect to Wi-Fi and the computer is connected
This suggests that the problem is not with the router or provider, but with the device itself. Although, the communication channel may be clogged and the router simply does not support a large number of devices. Try turning off the Internet on your computer or laptop and only connect from your phone.
The easiest way to solve the problem is to restart your phone. If it doesn’t help. remove the network. To do this, go to the list of available WI-FI, by long pressing the screen next to the name of your network, call the drop-down list and click the “delete this network” button (option: “forget the network”). Together with it, all settings will be deleted: the remembered IP address, DNS and other parameters. Then find the network you need again and connect to it by entering the password.
If this does not help, find in the “Settings” of your phone the item “Reset mobile Internet settings, WI-FI, Bluetooth”. It can be located in the “System” section or in the “Additional functions”. Reset settings, restart your phone and try to connect again.
All in vain? Download an anti-virus application to your phone and test it. Malicious software can intentionally block Internet access or disrupt access due to certain settings.
Wi-Fi is connected, but says “no Internet access
There are several reasons. First: the router is really not connected to the network at the moment or is working with errors. It needs to be rebooted. you can ask the staff about this when it comes to a restaurant or cafe. Or do it yourself: we recommend disconnecting the power cord for 2-3 minutes, at the same time checking whether the Internet and ethernet cables fit tightly into their cells.
Second: you are too far from the router, and it simply “does not reach” your device. Try to move. If this happens at home, move the router to a different location. perhaps there is some obstacle in the signal transmission.
Third, you have not completed your network connection. In many public networks, a mandatory requirement is user authentication on a special page that comes out after you click on the “connect” button. You may have prevented the page from opening. In this case, find the network in the list of available ones, click on it and select “Delete”. Reconnect and wait until the start page opens, where you will need to enter your phone number and the password that will come to it. If the page does not open automatically, go to your phone’s default browser and try to open any page. a window for authorization should appear.
Fourth: The date and time are set incorrectly in the phone. Check settings, enter correct data.
Fifth: There are problems with the IP address. Go to the list of networks and click on the one you need with a long press. Select “Change network”, then. “Advanced settings”. Here, in the IP setting parameter, set the value to “custom” and enter 192.168.1.X (where X1) (make sure that this data suits you by looking at the label on your router. There will be sure to indicate its IP address. The phone address will be those the same numbers, except for the last one.Choose it to your taste.)
Sixth: It is possible that despite the free network, the Internet is distributed only to the IP / MAC addresses of devices specified by the administrator, i.e. you won’t be able to connect without meeting the administrator.
Seventh: Perhaps the connection is being blocked by a “security program”: a firewall or antivirus. Try turning them off.
How to connect your phone to a public Wi-Fi network
In order for the phone at home to be able to connect to a wireless network, you need a router. It can be a laptop or a computer with a WI-FI adapter. The main advice: do not be lazy to put a high-quality password on the network and enable the WPA2 security type. You should not strive to be a good neighbor, this is fraught with many problems from running out of traffic to problems with the law if a dishonest person connects to your network.
It is enough to set up the connection once, in the future the phone will automatically find the home network.
Writes “saved”, but there is no connection, authentication error
If you are trying to connect to a public network in a restaurant or airport, for example, then the explanation can be very simple and offensive for you: the router’s connection limit is simply exhausted, it cannot cope with the number of devices that attacked it, eager to get into the network. This often happens in crowded places: at holidays, concerts. Any channel has a limit, and feeding the phones of thousands of voracious users can be difficult. Or an old router is installed and the phone simply does not support its settings. It is difficult to solve the problem in this case, it remains to wait or look for another network.
Also, a public network can be protected by a password and you do not know it or you enter it incorrectly. Try to talk to local employees, maybe they will reveal a secret for you, even if it is not a public network for all customers.
If we are talking about a home network, this error may indicate a freeze of the router. In this case, it can be reanimated by simply holding down the reset button or disconnecting it from the power for a couple of minutes.
If the error persists, go to the settings of the router through your computer (by entering the IP address of the device in the address bar of the browser), check that the encryption type WPA-2 is selected, the DHCP server is enabled. And yes, make sure you enter the correct password. on the router and on the phone. Even if it seems to you that you remember it by heart and there can be no problems with that. Sometimes, during the dialing process, an error may occur and you will not even know what character is in it: just change the password and try to log into the network again.
Also check the date, time and region settings on your phone and router. Their mismatch can lead to devices blocking each other.
