    rtl8192cu - Activation of network connection failed

    Hi,

    OS: Ubuntu 19.10

    I have a TP-Link TL-WN8200ND [Realtek RTL8192CU] wireless adapter. When it is connected the green led is on. But after trying to connect to my wifi network I'm getting an "Activation of network connection failed" popup message.

    I tried booting from a Live USB with the same result.

    I was following this thread: http://forums.debian.net/viewtopic.php?f=30&t=142930

    Here the resuts:

    Try
    Code:
    sudo rm /etc/modprobe.d/blacklist-rtl8xxxu.conf
    echo "blacklist rtl8192cu" | sudo tee /etc/modprobe.d/rtl8192cu.conf
    Reboot

    Re: rtl8192cu - Activation of network connection failed

    Try this one instead
    Code:
    sudo dkms remove 8192cu/1.11 --all
    sudo rm -r /usr/src/8192cu*
    rtl8192cu should be blacklisted. Reboot and show
    Code:
    iwconfig
    lsmod
