@memphis_cult
Can you post the output from lsusb

Edit: Waiting for the output but it’s possibly a realtek chip.

@memphis_cult
Try installing rtl8852au-dkms

yay -S rtl8852au-dkms

Then reboot!

Edit: It may also be a mediatek chip so if you could provide the output from the above command first would be helpful.
