Everything was fine before I enabled the the 5Ghz radio in my router and tried to connect to that with the pi4.
Showed associating...then right to idle.
Tried to connect again, crashed and the pi4 auto-rebooted.
Now I can not even connect to the 2.4Ghz as before.
Both bands when trying to connect show the failed message under connections, and a notification of 'Network Error: Input/Output Error'.
I wiped the card. Reinstalled, same thing no wifi anymore.
Wiped the card and installed offical Raspbian, same thing no wifi anymore.
The Pi4 can see the networks.... Associating... Idle... Failed... Network Error Input/Output Error.
Nothing else changed. Signal strength 74.
Back on fresh install of LE 9.2.1 repeatable OS crash upon: 1st trying to connect to wifi, (connect, associating... idle...), connect 2nd try (connect, associating.., fail..) and it crashes.
Basically after a rebeoot it crashes on the second attempt to connect to wifi.
Whether it crashes or not the situation is the same (if that helps some more). ...
Is there anything else I can add that would help anyone help me? I'd appreciate it much!
