Wireless Connectivity getting hanged.

[pulkit.sharma]

Hi,

I am facing a strange problem in my WLAN Setup.

none of my wireless clients are able to associate with Wireless LAN but when I delete and create a new wireless profile in WLC 4404 clients starts associating with WLAN. every 2-3 days I had to delete and create wlan profile.

Is it related to IOS bug or any other problem? My Wireless LAN Controller image is AIR-WLC4400-K9-5-1-151-0.aes.

Thanks in advance.

Hi,

Thanks for your reply.

Does upgrade changes the running configuration in the WLC. Let say version 5.1 to version 6.0 upgrade.

AFAIK, 5.1 config back up it is XML format and also on the latest... Just to be on the safer side please take the config backup and then upgrade.. Why 6.0?? Go for 7.0.116

Lemme know if this answered ur question!!
