My WiFi is showing "no WiFi networks found " and when I try troubleshooting it tells me to check my router?? I went to device manager and in hidden devices something called RAS Async adapter is hidden and shows this in properties

Could this be the reason my WiFi won't work? How can I get it to show up again

Yesterday my wireless adapter did the same thing and I reinstalled the driver and it came back

    Thanks for the clarifications.

    Your Wi-Fi network adapter is Mediatek. I don't believe the RAS Async Adapter is causing the problem.

    I suggest you do the procedures below.

    Reset network settings:

    1. Press "Windows + I" and select "Network & Internet > Advanced network settings";
    2. Select "Network Reset";
    3. Select "Reset Now", and at the confirmation screen, select "Yes";

    Note: The PC will need to be restarted.

    1. Now open Start and type cmd;
    2. Right-click on "Command Prompt" in the result list and select "Run as administrator";
    3. At the Command Prompt, type the following commands one at a time and press Enter:

    netsh int ip reset

    netsh winsock reset

    ipconfig /release

    ipconfig /renew

    ipconfig /flushdns

    1. Restart your PC and see if the issue is resolved.

    If it persists, reinstall the Wi-Fi driver as instructed below:

    Download the latest driver from the link below.

    https://download.lenovo.com/consumer/mobiles/2g...

    Source: https://pcsupport.lenovo.com/us/en/products/lap...

    Uninstall the current driver:

    1. Open "Device Manager" (Windows + X and select Device Manager);
    2. Expand "Network adapters";
    3. Right-click on the Mediatek adapter and select "Uninstall device";
    4. On the confirmation screen, check "Delete the driver software for this device" and click "Ok";
    5. Restart the PC.

    Install the driver you downloaded.

    Maybe you don't need to. Do it if the problem reoccurs.

    Hi MwaleNkandu.

    I'm David, and I'm happy to help you.

    Please upload a screenshot of all network adapters in Device Manager.

    Do you have a device with an alert or an unknown device in Device Manager?

    What is the manufacturer and model of your computer?
