Good afternoon,

I cannot get my wifi card to connect to a network. I can see a list of wifi networks, however, it fails to connect with the error periodically shown "Connection failed, Activation of network connection failed".

System: Ubuntu 21.04 with Windows 10 Dual Boot - No fast boot enabled in windows.

Wifi card: asus pce-ac88

The wifi works okay, albeit REALLY slow and patchy, with a cheap USB WIFI stick.

{Im using windows 10 along side Ubuntu 21.10}

so i found the problem with mine, so i used command ifconfig in nmy terminal and showed this:

enp5s0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500

by plugging this command you want to see if is there any other adapters in your computer to select, as you can see device "enp5s0" is being interrupted for many times and gives the code "Activation of Network Connection Failed" about 5 to 10 min so i want to disable, what i did was disable this guy by using command sudo ifconfig enp5s0 down since is selected up and i don't want to use it anymore and left the wlp11s0:Up so i want to use this adapter, for some reason i have to do this every time i restart PC or retart the NetworkManager, make sure you know your adapter name but in any case you want to change just replace the Down for Up or restart the network manager in the command, Hope this Helps, and yes i'm using the old fashion way of ifconfig this still works in UBUNTU 21.10
