Exactly how did it fail?  What commands did you use and what outputs were produced?
Also what is the VID:PID of the adapter?

If the adapter is PCIE based it will have an entry in `lspci -nnk` for USB it will be in `lsusb`.  Please post the adapters entry.

Re: tp-link T2U Plus wifi adapter

Is rtl88xxau-aircrack-dkms-git the aircrack package you were referring to in your initial post?
Is it installed?

pacman -Qs rtl8

What is the state of DKMS

Re: tp-link T2U Plus wifi adapter

Is there an interface listed in the output of `ip link` for the Wi-Fi adapter?  If so can it detect an access point?  If not what is the output of `dmesg`?
