Hi Sakid
How do we use the onboard GPS chip? We have a number of APs loosing
sync for periods of time and would like to try them on the onboard GPS
chip to see if it helps.
Also, how long does will the hold off timer (generate sync) keep the
AP in sync with other APs? 1 minute, 10 minutes, 1 hour, 10 hours, 1
day, 1 week? What did you find in your lab testing? i.e. How
good is the generate sync clock???
Thanks
Adam

Unfortunately, we don’t have an internal switch to flip the
connection. We have a way to communicate with the GPS chip and are
looking at ways to address this in SW.
As for the question on the hold off timer, that just allows the AP to
operate (without shutting of Tx) without a GPS signal during the
holdoff timer.

Hi Sakid
Will just selecting internal switch us to using the onboard GPS
chip? Or do we need to unplug the external puck (which would mean a
tower climb)?
Thanks

While this topic has moved to CnPilot SSID issue and CnMaestro, I did
want to chime in on the original GPS thread –
Intermittent GPS signal lost – The external puck we ship with the Aps
is a relatively high gain antenna and thus tends to be impacted more
from interference. We have seen cases of this from LTE (second
harmonic landing on top of GPS frequencies). The onboard GPS chip has
a lower gain antenna and in the case where LTE interference was the
issue we have seen a substantial difference when the puck was not
used. Unfortunately, it is a case by case situation and depends on the
environment. We are actively looking to find a better solution in
terms of an external puck while keeping costs low.
Lockup during upgrade – We have seen reports of lockup issues during
an upgrade. This is software related and the units are recoverable by
our support team via CLI access. The team will just need remote access.
Anything beyond the two issues qualify for a RMA and if you have an
unit exhibiting a different mode of failure, we would be keen to
investigate the unit here.
Thanks
Sakid

cnMaestro is capable of managing ePMP, PMP450, and cnPilot R and E
series routers. But they have to be managed in cnMaestro before any
config template can be pushed out to them. If you cnPilot routers are
managed by cnMaestro, then it is possible that someone accidentally
pushed a config to those routers. Best practice is to have a template
built for each customer. Then if this happens again, cnMaestro will
report that those routers are 'Out of Sync'. All you will need to do
at that point is resync the config and then about 5 minutes or less,
it will be fixed.

Pushed a template?
Not sure what that means.
At the time, we were fixing 3-ePMP AP’s and 3-R200 routers who failed
to upgrade a month ago with the KRACK firmware upgrade.
The 3-R200’s were all ePMP AP connections.
The 6 R200’s that changed to cnPilot SSID were all _connected to
PMP450 AP’s,_ which we didn’t make any changes to yesterday.
That’s the mystery – we were working with ePMP gear via cnMaestro, but
nothing on the PMP450 gear was touched.
The timing tells me there’s a correlation – with the timing yesterday
while working with ePMP via cnMaestro – but how did or can it
Affect PMP450 subscriber’s routers?

Not related, but want to spread the word…if anyone experienced
this odd event.
Around 10:30am Central Time yesterday, we started receiving calls
“Internet is not working”.
I was one of the ‘victims’ myself at my home.
Common denominator – all the routers are cnPilot R200 and R200P’s.
I logged into my home router directly at my home.
SSID in the router *_changed_* to “cnPilot”.
Once I changed the SSID back to the original SSID and re-entered
in the ‘password’ – it worked.
We’ve had 6 customers call in.
Asked them if their router name (SSID) had their original name or
did it change to “cnPilot”.
*Each confirmed – it said “cnPilot”.*
We’ve been able to remotely log in and correct things….but this is
STRANGE !
Will get a ticket going with Cambium to see what’s going on.
Thanks for the GPS information, will make notes on it.

I had that issue a few weeks ago where the 3.5.1 GPS upgrade
actually locked up the GPS board and wouldn't even initialize the
board to even turn on, even though the software was reporting that
GPS was active. Opened up a ticket with Cambium and they had to
run it up to one of their engineers to fix the problem. Ended up
having to map a Public IP address to the unit and open up ports 80
for www, 22 Inbound for SSH, and needed to make sure that 22
Outbound was open for the device to be able to communicate with
their SCP server. The engineer SSH'd in to the device and loaded
the GPS files to the unit from their SCP server and it fixed the
issue. Just remember to turn off all of those ports to the unit
after they're finished.

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.
