First, you need to check if there is Internet at all. If it is on the cable, but not on WiFi, then you need to check the WiFi settings. See if the WiFi indicator is on on the router, as well as on your PC, smartphone or tablet. If everything is included, but there is no connection, we look for the problem further.

First of all, check that the wireless icon on the router is on, then you can try to restart the router itself and the phone / laptop. If this did not help, we have a whole article that describes the reasons and methods for solving problems with WIFI https://softcatalog.info/ru/article/chto-delat-esli-ne-rabotaet-wi-fi-na-noutbuke Point by point, its content looks like this:

  • How do I enable the Wi-Fi adapter on my laptop?
  • Basic Networking Methods on Windows 7, 8, and 10
  • The device is working fine, but does not see the Wi-Fi router
  • Laptop does not connect to Wi-Fi after Windows update
  • Some More Ways to Fix Internet Connection Issue

Quite often, users cling to the button to enable wireless networks on a laptop or accidentally disable them with a function key. The button programmatically disables the wi-fi module, respectively, until you turn it on, the Internet will not appear.

The problem may also be in the drivers. Try updating them. If Wi-Fi stops working after updating Windows, you can try the following:

  1. In the search window of the Start menu, find the command line and run it as administrator;
  2. In the interface that opens, enter the command netcfg -s n and press Enter;
  3. A fairly extensive list of two main items Network Protocols and Network Services will appear, including information about various web services;
  4. If you find an item called DNI_DNE, enter the following commands in turn: reg delete HKCR \ CLSID \ {988248f3-a1ad-49bf-9170-676cbbc36ba3} / va / f followed by netcfg -v -u dni_dne;
  5. Close the program and restart your computer;
  6. Now turn on the adapter and check the wireless network connection.

Hello. My router is working, everything that should be on is on. But, no device finds Wi-fi. What could have happened ?! We rebooted already and turned it off for a day, it still does not work.

These 4 steps will help you diagnose and fix your wireless internet connection problem:

1. Reboot the device

Reboot is worth both the router and the computer that cannot connect to wifi. On the router, you need to press the shutdown button and wait 10 seconds before turning it on again.

2. Reconnect to the network

Go to the wifi connection settings. If your network name is listed, select “Forget this network” and then connect to it again.

3. Check your router settings

Call your ISP and check if your router settings are out of order. Each provider has its own requirements for each device model, so it is better to diagnose the router together with a technical support employee. This can also be done by phone. If some indicators do not light up or light up incorrectly, the provider will advise on how to eliminate the problem.

4. Update the driver for the adapter

Check the adapter connection in the device manager. If it does not work correctly, it will be written in the “Device Status” window. In this case, you can select the “Update drivers” option.

Sometimes, after updating the system, the adapter may not be detected at all in the device manager. Then you need to install drivers for it. You should look for a driver for an adapter in a laptop on the laptop manufacturer's website, since the adapter is usually built-in in it. For an external adapter, it is better to look for drivers on the adapter manufacturer's website. Restart your computer after updating or reinstalling the drivers.

Another way is to remove the adapter from Device Manager without removing its drivers (do not check the box next to this item when uninstalling). After rebooting, the driver will install itself.

If you still cannot connect to wifi, call a professional wizard to set up a wireless network or troubleshoot hardware.
