This really sounds like a LAN

This really sounds like a LAN or WAN issue, like Rasika already stated. There is a chance that you will find more information about the leaving AP's on the WLC if you go to Monitor -> Statistics -> Ap Join -> APXYZ -> Last Error Summary.

Need more information. Is

Need more information.

Is the AP controller-based or autonomous?

What do you "disconnected"?

How is the AP powered up?

Hi Rasika ,

My current WLC running with software version 7.2.111.3 . They reach WLC via LAN . earlier we had issue and we changed the channel setting in AP and Power too for other AP in the same campus .Recently we are seeing issue with some other APs in that Campus . Sometime we client roams between APs , still it is connected to previous AP until manually reset join the nearest AP .

HI Leo , Thanks .

Careful with making too many changes. It seems like you currently have two. One is the issue where APs dissassociate from the WLC or clients don't associate to the APs. The other now is that clients don't roam in other areas.

So did you fix the initial issue first and is the issue the AP dissassociate from the WLC or clients all drop and can't assiciate to access points in the area?

As far as roaming, the device makes the decision and not the AP. If your power is set high and or you have the lower data rates enabled along with enough go AP density, then clients don't have to roam due to your settings. You need to understand your RF and coverage which means knowing the overlap seen by the device. Client drivers also can be a reason for poor roaming especially when some devices work fine and a particular device or driver version shows poor roaming. You need to isolate the issue more, which means being out onsite and not really taking the information that they are telling you as accurate. Not being onsite to troubleshoot and asking them to test and provide you with feedback can make your troubleshooting go round and round. False information will bring you back where you started. This is from my experiences with customers wanting troubleshoot remotely.
