    Re: Ubuntu 20.04 Wired Slow Connection

    Change the mtu-value in your network profile to a number instead of "Automatic". Check your ISPs info for that

    P.S.: Did you install ndiswrapper as well?

  24. Re: Can't get wifi (AX200NGW) to work in Ubuntu 16 kernel 4.15, Acer Predator

    Why not trying 20.04? The official release is in 3 weeks, however, it should work anyway with rolling updates until release point 1
  25. [ubuntu] Re: rtl8192cu - Activation of network connection failed

    Try this one instead


    sudo dkms remove 8192cu/1.11 --all
    sudo rm -r /usr/src/8192cu*
    rtl8192cu should be blacklisted. Reboot and show


    iwconfig
    lsmod
