Wi-Fi adapter doesn't work with drivers installed.

English Network/Internet

Today I installed opensuse leap 15.2 and my wi-fi adapter doesn’t work.
My wi-fi adapter is a Trendnet TEW 809 UB/A and the chipset is rtl8812au.

I tried installing the drivers from morrownr and gnab but none of them worked.
The wi-fi adapter has a cable in between the USB port and the actual adapter and it cannot be plugged in directly.

I just did a google and found this : rtl8812au Kernel driver for Realtek 802.11ac 8812au wifi cards

There are few other posts in the forum reg this rtl8812au

Its an rtl8814au Chip, so please post your kernel Version to get the right Repo:

uname -a

localhost@localhost:~> uname -a
Linux localhost.localdomain 5.3.18-lp152.66-default #1 SMP Tue Mar 2 13:18:19 UTC 2021 (73933a3) x86_64 x86_64 x86_64 GNU/Linux

Add this Repo as root with:

zypper ar -f https://download.opensuse.org/repositories/home:/Sauerland:/hardware/openSUSE_Leap_15.2_Update Sauerland-update

Install the driver:

zypper in -f rtl8814au-kmp-default

Reboot and config your network, I would use for Wifi NetworkManager.

If a new kernel is released, you will get the driver automatically a little bit later.

Oh yup that works! Thanks.
