What holdover value are you using?

There was an issue with the previous version of GPS antennas, that came with
early EPMP1000's. If the GPS antennas you are using are the ones that came
with an E2K then you should have the newer model though. In any case way back
when there was an issue that the old antennas had in high noise environments.
We experienced that first hand. We haven't see the issue since replacing the
GPS antennas though. I think we still have the holdover timer set pretty high
though which might help you in a pinch until a real resolution is found.

I agree, but we graph the tracked/visible satellites on all APs, and
these ones would have, say 10 tracked, and then 0 for hours, then
10. It was hardly ever a gradual change. We were convinced it was
firmware, or a bad GPS receiver, or puck, etc. and went down every
road we could think of, because it seemed like it had to be one of
those. Out of the 4-5 sites we had with this behavior, every one
was permanently solved by pointing the pucks up, and I think all of
them were in close proximity to a cell tower.

We fought with losing
GPS sync on ePMP APs at a couple of sites. We had been
told to point the pucks south to get the best GPS signal.
There were several wild goose chases, as it seemed
upgrading/downgrading firmware fixed it, but only
sometimes. In the end, the solution at each of these
sites was to point the GPS puck straight up. Our best
guess was that there was something overloading the GPS
receiver in the direction we had them pointed. So
pointing them up, while not giving them the best signal,
minimized terrestrial interference. At least that's our
theory.

Well, I did check the forums and found
I'm not the only one. I'm going to try downgrading.
Was hoping to find someone here who has gone through
it so I dont waste time if it needs to be RMA'd :)
