Wireless Roaming issue WLC 5508

                   Hi ,

In our wireless infrastructure we are facing some issues in roaming between the floors when the SSID is using 802.11a/g only but things will be fine if we are using 802.11g only . Our controllers are 5508 with version 7.4.100.60 , we have two anchor controllers and two foreign ones and access points are distributed between the foriegn controllers . Please can anybody help tell me why we are facing issue in 802.11a/g ?

Good to see it is working for you now..

What you had previously (distributing closeby AP to different controller) is not a good design. It will always cause problems when roaming.

How does your APs distributed among these controllers ? Ideally given building APs should be registered to a paritcular controller &  in this way roaming can be controlled to a single controller (intra-controller roaming). This is the recommended design.

You have to narrow-down under what condition these problem occurs. To find out exactly why this roaming issue occur, you have to get some debug output. If you can re-produce the error with a particular client device, then get the "debug client " output of the WLC.

Hi ,

Actually the APs are distributed between the two controllers so we have 4 APs per floor . Each two APs in a controller so what i did yesterday is that i put all the APs in one controller and roaming after that is working fine with the a/g radio .

You do need to provide more info. Also, I typically would use radio policy all and then see if that's still an issue. You must have adequate signal coverage on both the 2.4ghz and 5ghz. Was a site survey done at all on your building.

Also post your show WLAN

The infrastructure has worked as you have changed the deplyment mode from the distributed AP to the controller.
