How to activate/use the wifi card (debian 11 installed)?

Hey there,

I installed a fresh debian 11 from here: https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-11.3.0-amd64-netinst.iso an I wanted to use it over WLAN/WiFi.
I tried to bring the adapter up by the method out of the download section from the wiki (“For Linux: copy all binaries to /lib/firmware/brcm directory and reboot.”), but it didn´t work.
How can I bring the adapter up?

Many thanks for your answers in advance.

can you send the dmesg | grep brcm ? Is your ROCK Pi X bought recently? It should be AP6254 wifi/bt module instead of AP6255.

Hi Jack,

yes, I bought it recently. On the bottom is “ROCK PI X 1.41” printed.
The output of dmesg | grep brcm is:
