Client get connected occationally with WLC 5508

Hi ,

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  6.0.196.0, and Client is Lenevo PC with XP.

Any suggestion? or some troubleshooting procedure I can follow?

Thanks!

Roy

Re: Client get connected occationally with WLC 5508

Let make things clear before we start blaming the 5508 as the culprit:

1.  Can the clients connect if using OPEN authentication?

2.  Can the clients connect if using PSK?

3.  What are the error messages on the clients and the controller?

4.  Are you using ACS, RADIUS, TACACS?

Thanks!

Seems some problem with open authentication.

On the Client, it reported cannot get associated.

on the WLC, while I am debug client it reports:

I am using remote radius with WLC only.

The strange thing is, when get connected, it looks fine, but I tried disconnect manually, then connect again, it reported cannot get associated, then I try again, it can get connect again,....
