We do similar though picked one day (86400) instead of 10 and then SNMP monitor the status. Figured it is better to have slightly off timing instead of completely down sector. Wish they were more reliable. Of course packetflux makes their injectors which work well.

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. Sakid Ahmed via Cambium-users <mailto:[email protected]> January 30, 2018 at 4:10 PM 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.

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.

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.

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.

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.
