I have one strange problem on wireless connection.
I just upgraded several 1131 APs to LAP with 2 new Cisco 5508 controller deployed, and we found the clients sometime can get conneted to the 1131 AP, and connection well, sometimes cannot. during our test, one conecion is ok, next one cannot, the third one seems ok again and again.
And we also have 2 new 1140 APs, seems no such problem,
The version for controller is 220.127.116.11, and Client is Lenevo PC with XP.
Any suggestion? or some troubleshooting procedure I can follow?
