I bought this USB wifi dongle and I tried to install it on my Kubuntu 20.04 (Kubuntu 18.04 LTS upgraded recently to 20.04)
$lsusb ... Bus 005 Device 002: ID 0bda:8812 Realtek Semiconductor Corp. RTL8812AU 802.11a/b/g/n/ac 2T2R DB WLAN Adapter ...
I followed this french tutorial that says that everything is in the repositories
So I installed
rtl8812au-dkms package, it worked.
Then I did
sudo modprobe rtl8812au and it also worked.
iwconfig still gives me the same result than before: my ethernet interface, my loopback interface and my PCI wifi interface.
The GUI in Kubuntu does not add me any new interface.
So, as advised in the french tutorial, I followed instruction "in case if another method does not work", which is to compile the driver :
sudo apt-get install linux-headers-generic build-essential git git clone https://github.com/abperiasamy/rtl8812AU_8821AU_linux.git cd rtl8812AU_8821AU_linux make sudo make install sudo modprobe rtl8812au
Everything again went fine, but still no new interface.
Have I done something wrong? have I missed something? Any help appreciated :-)
