When I set up my Piaware SDCard on my Pi4b when I went to enable the 5 GHz wifi it did not want to work. When I used the 2.4 GHz WIFI the piaware excepted it. Is this known or is it on my end?
I’ve had reports that some setups need to set
wireless-country in piaware-config to get 5GHz working. (Setting an appropriate country code gives the wifi system more information about the frequency bands and power levels it can legally use - the defaults are conservative)
Beside that the higher speed of 5GHz is not necessary for any flight feeding.
My second device is connected via 2.4GHz and runs with same performance.
Only if you need that performance for other things you could connect 5GHz
