Install wifi card RTL8852BE Debian 11 armbian-config not worked

Hello,

i have a WIFI RTL8852BE installed in the Rock5 Model B. And would now like to use the Internet via Wifi. I am still a beginner.

I use the official Rock5 debian https://wiki.radxa.com/Rock5/downloads which is installed on a SSD WD SN 570. I had thought it is set with the armbian-config. Unfortunately I have no access to the armbin-config.

I had tried
root@rock-5b:/home/rock# armbian-config
bash: armbian-config: command not found

root@rock-5b:/home/rock# apt install armbian-config
Reading…Done
Reading…Done
Build dependeny tree… Done

E: Unable to locate package armbian-config

I do not have access to the armbian-config. Can you maybe help me ?

Thanks

ok, it works: https://github.com/armbian/config and Run this utility on 3rd party Debian based distributions.

strangely, I have to re-enter the password for wifi after each reboot.
