Do you want to set one of the radios to my Unifi server to confirm it is or
isn't a controller problem?

If you simply turn off your controller you can confirm as well.  The
devices will run as provisioned until told otherwise.

Ubiquiti Networks UniFi UAP-PRO Enterprise WiFi System - hard to recommend
at this point. We saw people mention this brand here on the list - people
like them. So what could we have set incorrectly ? They drop link and
re-provision on their own at odd times day or night.


Drop link all the way down to layer 1? What does re-provision mean?
Lose/re acquire DHCP lease? \

What is your network topology? What kind of switches are you using? What's
the length of the cable runs? Have you had an electrician check your wiring?
How many access points are you running? How many fail? Do they fail in any
kind of cluster/pattern?

That's just the basic questions.

Lots more information needed if you want free support from the NANOG hive
mind :D

They have millions of satisfied customers in deployments from some of the
worlds largest shopping malls to multi state ISPs. Different gear across
that customer base of course.



We have completed everything tech support asked of us. (Really, lame
emails they respond with as if they didn't read your text - they won't
call and you can't call them). We used POE from ciscos - then changed to
their POE provided.


POE from ciscos.... mid span injector, or switch port?


 They didn't recommend it, but we plugged them all into

APC UPSes..... no difference.


The midspan injectors you mean? Hmmmm, wonder why they didn't want you to
put them in UPS. Did they provide any explanation?


 They all re-provision at different times

even when no one is connected or in the building at odd hours like 2am.
Each one does this 2-3 times per 24 hour period.


Interesting. Any repeated offenders?




Has anyone else experienced this?
Anyone know what we may have set incorrectly ?
Is this normal - do people put up with the 2 mins the APs are unavailable
about 3 times a day? (UniFi support acts like it's not a big issues.)


Do they come back on their own? What's the "downtime" time window?



 We use the UniFi controller on mac os x.


Mac OSX isn't a server platform. Sorry. Use Windows 2k12 or Ubuntu Server
(or your favorite debian or Redhat flavor). I've had zero problems on
either of those platforms.

What's the topology between the access points and your controller "server"?
