802.11a Down on AP1131 after upgrade

We have 20 Cisco AP1131 managed by a WLC 4402 on a site, I just upgraded WLC software to 5.1.151.0, but after reboot, most(18/20) APs show 802.11a DOWN (Not Supported), 802.11b/g UP. Any help will be appreciated.

Thanks

Hello Allan,

try to reset the APs and see what happens.

If this doesn't solve:

plan a downgrade of the WLC or open a Cisco TAC service request.

Hope to help

Giuseppe
