Wi-Fi issues

Hello, I use a wifi dongle to connect to my pc and it was working very well until now, but now my pc no longer wants to connect to my wifi and it has a very poor signal even though it works fine.

I am connected to it with other devices, I have tried everything I found regarding updates or anything else, I have tried everything, so for the moment I have connected an ethernet cable from the box to the computer but I don't know what else I can do?

My last solution is to change my wifi card in the tower?

    Hello,

    Windows + R
    Type --> devmgmt.msc and OK.

    What do you have in network adapters?

    I can't send the photo, now that I've plugged in the cable I have three networks but otherwise I have the same thing as you, and I tried disconnecting my network and restarting my PC, it didn't change anything.

    The TP-Link wireless is not working?

    The problem is indeed with the Realtek 8812BU?

    Right-click on the Realtek wireless card
    Uninstall

    Click on --> Action
    Scan for hardware changes
    Windows will reinstall the Realtek wireless device.

    I downloaded it but I can't find it once I browse to select the file, there's almost nothing even.

    Whereas when I open my documents next to it normally, I have everything.

    It's just impossible to find the file once I browse, it's in my folder on the right and I have what I need but on the left I can't find anything, I can't copy and paste or anything.

    once I browse, I can't find my file, I barely have anything in the folders.

    However, when I open my documents at the bottom left separately, I have everything I need...

    thank you very much for your help by the way, it's really a hassle and I don't understand how the computer can't connect to the wifi like that when everything is working.

    -->> Provided disk <<–
    -->> Browse <<–
    Select --> Desktop

    Go to the unzipped driver folder --> 77c8e9d7-.....

    OK
    Next
    Restart.

    You need to unzip the driver found on the desktop

    Right-click on the driver --> 77c8e9d7-......cab
    Select --> 7Zip
    Choose --> extract to "77c8e9d7-.....\"

    After that, install the driver manually as suggested.

    I can't find the file once I manually install the driver, but as I told you, it's there in my folder when I look separately.

    Did you manage to install the driver?

    OK, so is that the date and the version of the driver that is installed?

    2025-07-31
    1030.52.0731.2025

    If so, does it work for accessing the web?
