[SOLVED] Trouble with drivers for the TP Link 802.11ac wifi adapter

Greetings

I'm having trouble establishing a wireless internet connection. The device I have is the TP-Link 802.1ac, found from the lsusb command. I have tried the rtl8812au-dkms-git, rtl8821au-dkms-git, and rtl88xxau-aircrack-dkms-git drivers from the AUR, but something else must be wrong. The output of

ip link

is

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp5s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
    link/ether 18:c0:4d:55:ed:30 brd ff:ff:ff:ff:ff:ff

,
so I tried to start/enable with

systemctl start dhcpcd@enp5s0

and

systemctl enable dhcpcd@enp5s0

, but no luck. I have rebooted after each try with the different drivers. I greatly appreciate any nudges in the right direction in advance!

- Thanks

What really doesn't say anything. TP-Link rebrands various chips, even under the same model.
=> Please post the actual lsusb

The output of ip link

doesn't show any Wifi NIC, enp5s0 is your wired device.
You should™ have/get a lease there from dhcpcd, though ("ip a") as it has a carrier and is up.

Looks like that chipset needs https://github.com/RinCat/RTL88x2BU-Linux-Driver

It is in aur, https://aur.archlinux.org/packages/rtl88x2bu-dkms-git .
You'll have to build that package yourself, start with reading https://wiki.archlinux.org/title/Arch_User_Repository .
