Our AP subnets are /24s and latency appears to be under <1ms, which is
what I would expect as everything is fiber connected.
Thanks!

How big are your subnets the APs reside on, and how is your latency
from the controllers to the APs? I know the APs are latency sensitive.

We installed around 700 over the summer in our residence halls as well.
I've seen the same issue. However we've never had WCS until the same
project. I'm starting to wonder as well.
Yup....it's a Droid !!!

I'm curious if any Cisco users out there are experiencing or have
experienced what we're seeing on our campus. This past summer we
installed 3502i's in all of our residence halls - approximately 500
total. Ever since the students have moved in, we will get messages
from WCS stating that "AP XYZ" is down and disassociated from the
controller. When I check out the AP, the uptime is fine, but the
"CAPWAP join time" is for like 30 seconds, or however long it took
me to check.
We've tracked this and it is totally random as to what AP will drop,
which makes troubleshooting this very tough. The log on the AP
isn't helpful. I'm working with TAC who suggests that keepalives
are getting missed. I'm not sure why that would be the case since
we have another 500 or so APs on the admin side that very rarely
drop. Adding to that, when the students left for break, the AP
drops stopped. They came back, and sure enough, the drops start up
again.
I will say that the AP always joins back immediately, but for the
time that it does drop A) I'm sure connectivity is affected in that
area and B) we get an email.
Anyone experiencing this?
Thanks,
