Add AP15 to XG-Firewall does not work

Question

Hi, i have a problem. 
 
 I use SFVH (SFOS 15.01.0 MR-2) with home licence on a shuttle barebone. Bevor i use UTM with home license and 2 AP15 - this runs fine. 
 Now i changed to the XG and the AP15 are gone. 
 In the dashboard i could see 2 pending Wireless APs. After clicking i landed in the section "Protection > Wireless Protection > Access Points". There i could see in the section "Pending Access Points" the text "Loading..." and nothing happens. 
 I don't use "Bridge to VLAN", but "Bridge to AP LAN". The frequency band is 2.4GHz. 
 The DHCP of the XG give booth APs a correct IP. 
 Booth APs are ping-able. 
 I made a new "Access Point Group" and could add both APs as new items. 
 
 Now i need to accept the APs. But it is not possible, because of the running "Loading...". 
 
 I need help please! 
 How could i use my AP15 with XG? 
 
 greetings Max

Hi all, 
 I managed to solve my issue with the AP15 not showing up on XG. I'm posting this here in the hopes it may help someone in the future. 
 I upgraded my XG from MR2 to MR3 hoping this would solve the issue, but it did nothing to help. I logged a support call with Sophos and they diagnosed the AP as having a corrupt firmware and would replace it. Ok that is fine, but I thought that doesn't sound right. The AP was working fine on UTM 9.3 and then suddenly not on SFOS 15. I moved the AP back to UTM 9.3 and it worked as before. I figured I'd have a look in the backend of the SFOS software and see if anything obvious shows up. After a quick look around, I managed to find what I thought might be the issue. Turns out it was and now my AP15 is working as expected. 
 Here are the steps I used. Beware as you can cause all kinds of damage by using the wrong commands in the advanced shell feature of the firewall. In these instructions 15.01.0 MR-3# is the shell prompt. 
 1. SSH into the the XG firewall 
 2. Select 5. Device Management 
 3. Select 3. Advanced Shell (This will drop you to a linux shell in the /tmp directory) 
 4. 15.01.0 MR-3# cd awed (change to the awed directory) 
 5. 15.01.0 MR-3# ls (show the directory contents) 
 6. In this directory you should see 2 files matching the Serial Number of of your APs. The 2 files will have an .ap and a .apcfg extension. 
 7. 15.01.0 MR-3# rm <APSerialNumber>.ap* (This will remove the configuration for the access point) 
 8. Within the XG appliance admin interface you should now see the AP as a pending access point. 
 9. 15.01.0 MR-3# exit 
 
 Hopefully this helps somebody out and can save a lot of frustration. 
 
 Cheers, 
 Matt.
