Can't set up USB wifi adapter

After installing the drivers, I try to do the following:

 ip link set wlp0s2u10 up 
RTNETLINK answers: Operation not permitted 

Additional information: EW-7811utc adapter, using rtl8812au drivers from AUR.
Happy to provide any more information, but I'm not sure what else is relevant as I am new to Arch.

I have followed the steps in the wiki under 'Wireless Configuration Guide', but cannot get past this.

Things that are not the issue:

  • I'm root, so it's not that I left out sudo

  • It's not a physical wifi button issue, I've checked rfkill list and it is not blocked

  • The adapter is not broken

That comfirms the rtl8812au driver is needed, but aur has 6 packages for that, see
https://aur.archlinux.org/packages/?O=0&K=rtl8812au

Which of those are you using kennethdarragh ?


Multi-init booting with apg Openrc and systemd coexisting
Automounting : not needed, i prefer pmount
Aur helpers : makepkg + my own local repo === rarely need them

Install the rtl8812au-dkms-git driver as well as the linux headers.

You need to provide better info if that doesn't fix you up.

The driver from 'kimcoder' worked best for me (stable throughout kernel updates):

Did you do that as root?
