The power supply im using is working fine i fixed that issue

The issues i keep running into keep changing
now for some reason when i try to set up the wifi country in the retropie settings i get an error saying "could not communicate with wpa_supplicant" and then it says "there was an error running option I4 change wifi country" what do i need to do to fix this issue? i believe it is because of this that the ethernet on the raspberrypi isnt being accepted either
