4 Wireless AP inactive after Sophos restart

Question

Hi, 
 we had a planned power failure 2 weeks ago, and since then four of 13 wireless AP&acute;s AP55 are inactive. We got some other AP55&acute;s with no problems. 
 The AP&acute;s itself were not affected by the power failure. They can be pinged in the network. A restart of the AP&acute;s didn't work. 
 Our UTM9 has version 9.510-5. But in the in between the system got a few updates and restarted a few times. Nothing helped. 
 I removed one of the AP&acute;s in the webadmin console, but it didn't appeared yet. 
 
 Here a snipped from the wireless.log
