hi granul
Every used hardware is started as a module (if I remember it right)

so look as user root in your favorite Terminal /Konsoleroot

enter
if rtl8812 / rtl8812au is your module

enter
to start / load this module

if the module is loaded correctly
you configure your wireless network
maybe via network-manager or other app

at the moment, i'm, working with linuxmint, debian, ubuntu, pclinuxos
in the next 2 weeks i will try deepin ...

Do you also activate your WLAN Hardware ( a little switch ) ?

(( if you dont have luck, you've get the sources and compile the driver ))

bye Hans
