Wifi not working on debian 11 image

#1

Greetings, i’m trying to get debian 11 bullseye up and running on my Rock Pi 4B using the specified image (rockpi-4b-debian-bullseye-xfce4-arm64) found here: https://github.com/radxa/debos-radxa/releases/tag/20221201-0835

so far working fine, however i seem to be missing wifi drivers and am struggling to get it working.
at least wifi device with mac address exists as seen here:

rock@rockpi-4b:~$ ip a
1: lo: <LOOPBACK, UP, LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1
   link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
  inet 127.0.0.1/8 scope host lo
      valid_lft forever preferred_lft forever
  inet6 ::1/128 scope host
      valid_lft forever preferred_lft forever
2: eth0: <NO-CARRIER, BROADCAST, MULTICAST, UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
   link/ether 1a:6f:c2:0f:c8:60 brf ff:ff:ff:ff:ff:ff
3: wlan0: <BROADCAST, MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
   link/ether 6c:21:a2:38:08:52 brd ff:ff:ff:ff:ff:ff

i installed network manager applet for xfce4 and it just says “device not ready” for wifi networks. I also tried using a wifi USB-Stick and that works immideately giving me options to connect and such.

Question is, how could i get the onboard wifi ready / working?

I have been trying to get WiFi working on my Rock Pi 4C plus for over a year. I try new distros as they come available. So far nothing works. Radxa support just stonewalls. They ignore the problem. I am not a newbie!! At 83 I have been in the business longer than any one of their tech support staff has been alive. Radix is not an honorable company! They don’t stand behind their product!
