[PROBLEM] Losing wifi at power glitch

[malcolmwa]

Whenever we get a power glitch (losing momentarily)

You mean a 'brownout' ?     where the power is interrupted but not for long enough to cause the Pi to shut down completely ?.

If so you may be interested in this device that uses Supercaps to power the Pi temporarily in such instances..

I do mean a brownout.  I like your suggestion but I am running off 12v power (brick from laptop).
