Reverting "linux-firmware-raspi" from "12-0ubuntu1" to "10-0ubuntu1" resolves this issue.

I also noticed the same issue. On a fresh install of Armbian on the RPi5 the wifi works fine. As soon as I run an `sudo apt-get upgrade`, one of the upgraded packages breaks the wifi connection on the next reboot. 

 

Unfortunately for me, the fix in this thread didn't work for me. The wifi card see's the ssid's of all the networks around me, but when I try to connect, I see the following in the syslog:
