For the hold off time, we moved all of ours to the maximum (864000) after
having a couple of ours go offline due to the GPS. We tend to not alert
ourselves on customer outages, only infrastructure, so we missed it the first
time until customers called us. Now, we SNMP monitor GPS as well and have it
page us on a failure - but the long hold off helps.

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 with
the product team.

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.
