AP1131 won't show up after WLC upgrade

Unanswered Question
Aug 21st, 2009


I just upgraded WLC 4402 from 5.2 to 6.0, but after reboot, I can see all the AP's are "downloading" software, and then all gone, they won't show up any more.

Please help!

I have this problem too.

Check the time of your WLC, it may not have sync-ed with an NTP source.

Set the correct time or NTP source and check again.

Please check at the AP console for debugs. Enable "debug capwap client events" on AP

Also make sure , you have capwap ports open .

Ok now. I added a new IP scope last week, and all APs received new ip addresses from this new scope - different subnet from managment-port.
