I have a controller AIR-WLC2112-K9 with LAPS 1250, the clients could connect without problems some weeks ago , most of the clients are LAPs, some are Mac and a few
are iPads.the security is WEP encryption.
Suddenly the ipads could not associate to LAPs, a message is displayed about passwords but the passwords are correct, temporaly I solved the problem
after changing to WPA -PSK but the following day the problem came up once again. With Macs the problem is that they can not associate or many drops connection
In my case a have a LAP and I don't have problems , I can associate whenever I want , and other Laps also.
I planning to upgrade to AIR-WLC2100-K9-6-0-196-0.aes but I'm not sure if this will solve the problem.
any suggestion ??
Have a read of this:
If you're going to upgrade to a higher firmware version, then Cisco recommends 7.X.
