(solved) where can I find driver for the RealTek RTL8812BU and RTL8822BU Chipsets

[waldmattis]

Good afternoon!
where can I find a driver for the RealTek RTL8812BU and RTL8822BU Chipsets?

I have a stick Realtek 8822BU wireless LAN 802.11ac USB NIC

Product on amazon:
https://www.amazon.de/YOFOKO-High-Gain- ... r=8-1&th=1

The stick works fine with Windows 10, but not at all with MX on the same laptop.

Who can help?
Regards
Karll

Hello Karll,
I use a Realtek usb dongle and I'd recommend you first do a search on the forum using the keys words Realtek 8822BU. That should lead you into several discussions about said driver. I've found the advice from timkb4cq very helpful in the past. You could also search github for driver information - see https://github.com/morrownr/88x2bu

Edit: Been Ninja'd :)


P.S. If you like, you can also wait a bit for 6.2 kernel, (if I'm not wrong it says there 6.2 will be already supporting that.)

@Huckleberry Finn

Thank you for your advice.
I know these two sources but do not know
how to install/ compile the drivers

Regards
Karl

[Huckleberry Finn]

You can skip the first steps (as they are already installed ootb) and (all at once for you):

Code: Select all

mkdir -p ~/src ; cd ~/src ; git clone https://github.com/morrownr/88x2bu-20210702.git ; cd ~/src/88x2bu-20210702 ; sudo ./install-driver.sh

[Huckleberry Finn]

Shortly, this will create a src folder in your home and download all there, then will run the install-driver.sh in ~/src/88x2bu-20210702/

@Huckleberry Finn

I followed your advice.
Please see the terminal output:

Synaptic search many hits for gcc.
Please see attached screenshot

[Huckleberry Finn]

gcc-10 is already installed and the maintainer says it's ok (tested with) 10,11 and 12.

So, just install the gcc

(the one above the gcc-10 in the picture)

[Huckleberry Finn]

... If you have closed that terminal , you can then go on with this:

Code: Select all

cd ~/src/88x2bu-20210702 ; sudo ./install-driver.sh

@Huckleberry Finn

Thank you so much for your help!
Now the adapter is working fine.

You helped me so often in the past and again today.

Without your help my MX-installation would not work so excellent as it does.

Thank you
Karl
