    TL-WDN4200 - Problem with connection [Ralink 2870 USB chip]

    Hi
    I have problem with wifi card TL-WDN4200 . When I download with full speed (ex. torrent) after few minutes I have problem with internet. I have connection with AP but I can't use internet even connect with router by website (192.168.0.1). After plug out and plug in everything works good but problem is repeating.

    Re: TL-WDN4200 - Problem with connection

    this is going to be a tricky one to set up and I do not guarantee by any means you will succeed as I have no means of testing myself. It should work okay but if you proceed it is at your own risk.

    so first things first download the linux zip from this page

    you'll also need to install the development tools group
    Code:
    sudo dnf group install "Development Tools"
    aswell as dkms and kernel-devel
    Code:
    sudo dnf install dkms kernel-devel
    first blacklist the existing ralink modules

    then follow the first post in this arch forum thread from step 2 onwards

    afterwards reboot.

    If anyone has a better solution, now is the time to share it please
