Wi-Fi usb dongle not detected by NetworkManager

Can't connect to Wi-Fi as it isn't getting recognized by NetworkManager, ran

rfkill unblock all

just in case I had it there, but nothing.

Re: Wi-Fi usb dongle not detected by NetworkManager

you will need to compile the driver, quick search found:
https://github.com/kwankiu/rtl8851bu and https://github.com/neatojones/rtl8851bu
you will need to adapt an existing aur dkms package like this one:
https://aur.archlinux.org/packages/rtl8852bu-dkms-git

if you dont know how im sure someone will here will, i dont have time today sorry
