WIFI is very flakey on this. Half the time I boot it's not on. Can see by symbol in upper right.
Wifi and Blu tooth will kill battery. When done turn these off.
For now I am turning these on since they make setting up controls much easier.
sudo raspi-config
System options.
There is a seperate wifi option under retropi system. Turned it off. Going to disable symbol as well cuz it takes up to much screen space.
