Thank You Charles,
Been on NANOG a while - all the basic stuff we know well. Like, cables, 
cluster occurrences etc. Looking for the UniFi specific experience. Its
not the switches, power, cables, ports show no CRC issues etc.

We even setup another network with just 2 and it happens randomly - so its
some code or something.  Think I'm going to let one of the guys here login
the the controller and see if we missed a setting in the latest code.
NANOGs real good at having someone with specific targeted knowledge
appear.

Thank You
Bob Evans

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"?
