Lee,
In case you (or others) are still having this issue...
Not sure if this is exactly what you are seeing, but we had a similar
problem where clients would "jump" between AP's or could not connect at
all (if all AP's in the area were affected).
This condition is that under WISm code 6.0(182.0), the AP's actually
stop beaconing for 10 second intervals which essentially will not allow
clients to connect (or force them to other AP's which creates the
"jumping").
See Cisco Bug CSCta29484

If you suspect this on an AP, you can telnet/ssh to AP and issue this
command repeatedly:
show controller dot11 0 | i Beacons
and see if the beacons are going into the disabled state.
Code 6.0.188.0 fixes this

Wondering if anyone else sees this condition in a Cisco LWAPP/CAPWAP
wireless environment:
We seem to have occasional spates where select APs are clearly beaconing
SSIDs, but clients cannot connect.
Sometimes it’s a single AP, sometimes its many APs on a given controller
(never multiple APs on different controllers that I can recall).
Our fix is to reboot APs or move APs to other controller, instantly
cures the issue.
The impacted APs will be fine for weeks on end, then just abruptly cease
functioning, except for the SSIDs being in plain sight.
Affected clients are all OS types and versions- all similar condition-
see the SSID, but no connect.
I’m not faulting our system at this point, just curious if anyone else
has seen similar. (It is not a matter of MIC protection timer, fwiw)
Thanks-
Lee
