Hmm. Yeah, I'd open a ticket with Cambium and let them poke around in it
and possibly RMA. If it was a bad receiver flash, maybe they can recover it.

Thanks George but a power recycle was the first thing I tried. Then I
tried a reset. I've upgraded these things many times, including the
GPS, but this one hated the idea!

This looks like the classic issue where the GPS is locked up,
which is obvious because it's not even seeing the receiver
version/info. Power-cycle the radio and see if the GPS comes back.
If it does, then it should say if an update is needed. If it's
3.20_8174, it needs 5.1_8174. It's just a GlobalTop GNSS and I
imagine Cambium has been working with them to resolve the lockups.
In fact, read the 3.5.1 release notes where it talks about the GPS
update to address the lockups. The GPS firmware is in the same
3.5.1 release package and you just upload that for a GPS update.
The GPS firmware is NOT updated when you upgrade the radio
software. It's a second manual process. The 2k's all have the
GPS+GLONASS GNSS and are much more reliable. Could very well be a
h/w issue though, but try the power-cycle first.
I have APs not even using the external puck and they're tracking
10+ sats just fine. Primary sync is a PacketFlux injector.
Remember, the receiver itself inside the case has an internal antenna.

What version of GPS firmware do you see? Monitor > GPS Status?
Should be reading AXN_5.1._8174
Just grasping at straws.

Correct. This is NOT a puck problem. The satellites were coming
is strong BEFORE the firmware upgrade. I tried downgrading today
but that did not help either. See the attached pics. Looks like
RMA time.

No satellites doesn't sound like poor signal to me.

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 :)
