    Ok, no issues visible from the driver POV. Lets go into the NWM:

    Code:
    sudo sed -i "s/wifi.powersave = 3/wifi.powersave = 2/g" /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
    sudo systemctl restart network-manager.service

    Ok, thank you!

    I had no outputs from those commands and I'm getting the same Activation of network connection failed after trying to connect to my wifi network.

    Re: rtl8192cu - Activation of network connection failed

    You might need to disable IPv6 on the wifi connections in Network Manager and set your country code with
    Code:
    sudo iw reg set AR
    Some of the AP's in range have TKIP encryption enabled and that might cause problems. If this doesn't help you might need to file a bug report against the kernel

    Ok. Thank you. I'm getting the same message after that command. I'm gonna check how to report a bug.
