In modern realities, it is impossible to imagine your life without a laptop and access to Internet resources. Wireless networks literally enveloped the spaces and streets of cities. However, there are unforeseen situations when your favorite gadget stubbornly does not see the wifi network.

Why the laptop does not see Wi-Fi?

A laptop may not see the wireless network for many reasons. First, you need to make sure that there is wifi in this particular area. For this:

• Other available devices are useful: a smartphone, tablet, PC and others. It is necessary to check whether they see the network. If so, continue searching for the problem. If there is still no wifi, then recheck the parameters of the router.
• Check if the network adapter is on: it should be highlighted with a special sensor. Also, the adapter is turned on with a simple key combination Fn + from F1 to F12
• A search for an available network is accompanied by a flashing yellow asterisk near the antenna icon.
• If the search failed, then you should run the problem diagnosis center. In most cases, the suggested recommendations help in locating the network.

Often there are situations when the laptop stops seeing wifi after repairs or routine cleaning from dust and dirt. The wireless module may be accidentally disconnected or wiring damaged. In this case, it will only help to re-parse and connect functions or, in the case of physical damage, replacement with a new module. It does not hurt to also check the gadget for the presence of a mechanical button or switch adapter. Often, the user touches the inconspicuous lever and does not even suspect it.

Attention! Before setting up, it is advisable to read the instructions for connecting the gadget to wireless networks. It may be possible to find the nuances that were previously missed.

Why the laptop sees, but does not connect to wifi

Also there is a situation when the laptop sees the network, but does not connect to a specific network. Such a problem often puzzles inexperienced users, because the malfunction can be not only in the PC. However, it’s not worth worrying about, because in 85% of cases the reason is clear. This is due to the fact that in human settlements there are about 10 distributing routers per signal for receiving information, and each new point is looking for a free range. In the settings of wireless networks specified search range in the automatic mode. Thus, when you turn on the laptop, wifi does not connect due to the erroneous setting of the neighboring connection. Consider possible solutions to the problem:

1. Change the channel width of the router. To do this, go to the interface of the router, open a new browser tab and enter the ip-address there. The data is usually written on the cover of the router, and more accurate information is easy to find on the Internet. Next, find the section responsible for the wifi connection and change the channel width to a point other than auto-mode. At the end of the work it is necessary to restart the router.
2. Try changing the channel refresh rate in a part of the scan interval. To do this, in the column "additional" properties of the adapter, change the value to the minimum. This is the period during which the laptop will scan the surrounding area for the presence of wireless networks.

It also happens that the gadget sees all the available networks of neighboring offices or apartments, and the desired access point is not listed. In this case, the search is carried out near the router, as close as possible to it. This is done when the laptop is purchased quite recently and the settings are refined. It is possible that the settings or the distance from the point of distribution of the signal does not allow you to connect. If the gadget catches the network near the router, then you need to check the settings of the latter.

Where on the laptop settings wifi

If you have already tried many of the recommendations presented, you should check whether wifi is connected on the working device. To do this, right-click on the connection icon and locate the Network and Sharing Center. There is also the possibility to change the parameters of the adapter and turn on the wireless connection. There are cases when they are disabled by a random keyboard shortcut, which is designed for air travel. The main thing is to have a badge with a yellow star symbolizing the accessibility of the network.

In windows 8 models, verification is done through the control panel and PC settings. A check mark in front of the wireless network must be enabled. In XP, the adapter will connect automatically, and nothing is done manually. In the seventh version, the corresponding icon is searched in the Network Control Center, which has already been described earlier.

An important part is to check the wifi adapter. The search for the network and its uninterrupted work depends on him. In most laptop models in order to save battery power, quick disconnection and connection to the network is provided. Usually distinguish the following problems:

1. Hardware failure of the adapter, which is extremely rare.
2. The wifi adapter driver is missing, or it is installed incorrectly. This often happens on new devices or after replacing the OSes. For example, in some versions of windows, the driver has to be installed manually.

To do the necessary verification, it is enough to find a device manager through a search. In the corresponding tab, find the adapter with the name “Wireless”, or “Wi-Fi”. If it is missing, then you need to download a special utility through the official website of the manufacturer. If there is an adapter and the wireless network does not work, then:

1. Right-click on the icon and select the "properties" section. The window should say that the device is working properly.
2. Then again point to the adapter icon with the right button and select the "enable" option.
3. After the done actions, everything should work. You can also reinstall the driver and reset the settings.

Important! There should not be a triangular emblem near the adapter icon with an exclamation mark inside. This means that the driver is not working properly.

How to connect a laptop to Wi-Fi in such cases

Disabling wifi may occur for reasons unknown to the ordinary man in the street, and each time they may be different. There are a couple of simple ways that can help:

• It is useful to turn off the power module of the router for 10-15 seconds and turn it on again.
• Helps and reboot the system.
• Do not forget about the diagnosis of the adapter. Periodically, the virtual assistant gives valuable recommendations.
• After reinstalling the operating system, remember that the drivers that worked on the seventh version may not dock with the eighth version of Windows.
• Check the WLAN auto configuration service responsible for network adapters. If it is not running, then the adapters will not be able to start. You can find it through the start menu and the WLAN auto-tuning service. It just needs to be activated.

Check the settings of the router. They can stray through no fault of the user. There are also funny cases when someone from the family members changed their password and forgot to warn about it. If the icon is a muted shade, then click on it and click to connect, after finding out whether the password has changed. Next, you should look into the settings of the router. This can help the wireless setup wizard. Of course, a lot depends on the parameters of the router itself. But, the main thing is to make sure that the wireless connection is checked.

The user himself sets the network name and password to log in, and also selects the mode. Study the section on LAN network data and change the characteristics depending on the provider.

Reference! For quick access to wifi, try using the Fn key combination + the wireless icon.
