Up until now I was able to solve problems myself but this one is odd. I have searched the net and this forum but could not find anything that solves my issue.
All of a sudden so it seems I can not see or connect to 5 GHz WiFi anymore.
On various manjaro machines.
I take this Thinkpad T450 for this thread.
I tried different kernels, checked my WiFi regulatory domain, switched from wpa3 to wpa2, checked channels and even tried a different router/network.
Interestingly this happens on different computers, that previously all connected to 5Ghz.
Here is info on one machine I selected for troubleshooting:

Odd thing is one manjaro DELL machine can happily connect to 5Ghz wpa3.
Maybe someone could point me in the right direction.
Any help would be greatly appreciated!
Thank you in advance.
