We have a pair of 1232 APs configured as root bridges, and a single 1232 as a workgroup bridge configured as mobile.
What happens is the root bridges come up OK, and when we power on the WGB, it connects to one or the other of the of the two root bridges, and traffic runs fine. Authentication is WPA-PSK.
After about 10 minutes or so, we see messages on the two root bridges about too many errors, and the client is disassociated. From that point on, the WGB will not re-associated until it is rebooted. Sniffing the air, the two root bridges are beaconing ok, but the WGB never probes or anything, it just gives up. From the console on the WGB, it thinks the radio is up, and it all looks ok, it just never tries again.
I had something similiar with AP 1210 and a warehouse environment. Through the heavy roaming the memory consumtion grown over 80 percent. Then at any point above 80 percent the AP does not react to any association request until rebootet.
