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

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.

Sounds like someone pushed a template from cnMaestro.

Thank you for the heads up. First I have heard of this. I am sharing

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.
