Hello Cambium,
At the MidWest-IX launch party last night, several of us Indiana WISPs
compared notes on the 'cold weather' problems we are seeing with ePMPs. It
was very interesting to learn we are experience identical problems across
the spectrum.
We all understand this is a DRAM issue with
Tell me about it.. first decent snow here today, and one of our sites is
having issues (only the ePMP). I think we have completely lost one AP. We
are going to try and feed it 48V (it's currently 24V) and see if that
brings it back to life.

I wish they would fix/replace the bad 450 AP's that suffer from Watchdog
Resets.
Although replacing 100 450 AP's is cheaper than ePMP. :-/

It doesn't make any sense to me that it would... I certainly haven't seen
any difference in performance, and every AP that I've put the RC firmware

A bit of an update from the PacketFlux side.

This is not necessarily related to the cambium DRAM issue. I don't want
to claim that problem, since this isn't the same thing. This is more of
an issue where you have ePMP's which seem to start having power-related
issues. If moving to a 30V brick makes your p
