I did wait for a few days now :)
The message about reconfiguiring the wifi appears every time I turn off and back on the wifi in mmi settings. Maybe after the firmware update they added something to the firmware that block 5ghz in specific countries....
Ok, my adventure continues. Two things happened meanwhile: I received the OBD11 module and my car went for a service and the mmi software was update to 3281.
Now I can't see the 5ghz wifi again... Tried playing with all the settings in 75 and 5f (now I can access it) bit the new wifi doesn't...
Ok, switched the 5 ghz channel to 40 (guess 149 is blocked on my phone) and now I see the 5ghz wifi. But android auto still demands usb cable. Will try with an iphone later.
Meanwhile, I found 5f code (20103) it claims to accept it but "adaptaion" menu is still greyed out...
I got a 2020 a4. Connected with vcds and changed the settings in 75 module (including enabling android auto wireless). Couldn't open adaptetion for 5f module as I don't have a security access code. Nothjng changed... Still see only 2.4 ghz wifi.
