Hi. I have same error with connection on
Armbian_21.08.1 Bullseye/5.10.60. NetworkManager cant connect to wifi and try to do it a lot of times. As you know at 5.10.60 mac is stable out from box.
On Armbian 22.08 Jammy/5.15 wifi works good but it has problem with random mac. However if i used same Service script, mac becomes stable and problem returning like on previous version that i tested.
IMHO random mac looks like a patch for some previous versions that breaking stable mac setting
