WLC upgrade from 5.1.151 to 7.0.116

[Aabed Khalifa]

Dears ,

I have upgraded my WLC from version 5.1.151 to version 6.0.202 and then to 7.0.116 .

Since when , I see that all clients are disconnected every around 20 minutes and re-connected again .

Does anyone has any clues ?

WLC is 4402

AP are AIR-LAP1231G-E-K9 and AIR-LAP1242G-E-K9

when the issue happens.. what does the logs say?? in the mean time.. disable the session timout on all the WLAN on the WLC..

WLC GUI >> WLAN >> WLAN EDIT >> Advanced >> Session timeout >> Uncheck

Regards
