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

[David McGough]

The 1st thing to always try is a different/new power supply.  This is the 
#1 source of all problems with RPi boards.  Also, do you have a source of 
backup power?  If not, have the number of brief power drop-outs 
(brown-outs) increased?
