[arm-allstar] unstable WiFi connection on new rPi model 3 B node

[Jim Kinter Jr.]

Hi David,

For all my PI's I power them from a 12VDC 1A or better wall wart 
feeding a Hobbyking UBEC that outputs 5VDC up to 3A, and have never 
had issues with power on the Pi's.
As far as I can tell, all else on the bad-wifi Pi is working fine.

KTF
