Hi all,

I’ve not had much luck on the forums, so I thought I’d see if anyone here has 
some tips on how to track this down.

Lots of info in this thread:

http://community.ubnt.com/t5/airControl-v2-Beta/Debugging-devices-going-quot-offline-quot/m-p/1717755/highlight/false#M13316

I can find no commonality in the devices that fall off:

- I see 5.6.x, 6.x, and 8.x versions getting false downs
- I see APs, CPE, ac, n units getting false downs
- When checking if the units are reachable, I run my tests from the host 
running AC2 to eliminate any routing weirdness
- The devices always reconnect immediately when I manually ask AC2 to reconnect 
the device

What should be noted, is that AC2 (and all our other stuff) is running on AWS 
instances.  I tunnel the traffic back to each PoP with a VPN from AWS to each 
tower.  The RTT on that link is usually about 50ms.  For now, I’d settle on 
some recommendations to make the check a little less aggressive in case I’m 
just measuring blips between AWS and Fairpoint.

Thanks,

Charles
