DHCP lease renews every minute - inactiv access point

We have the following problem with a XG85w and a Sophos AP55.

The ap connects to the firewall -> Receives an IP via DHCP -> Is listed and can also be added via wireless protection -> But the AP will only appear as inactive on the firewall.

- the cables / port have already been replaced / switched  
- the ap connects to the internet and packets are coming back

The AP is always pingable always for the same timeperiod ~ 35 seconds , then it stops for about 1 minute and continues like this all the time.

This is the awed.log output:

  • Hi

     

    thanks your reply! Unfortunately, I cannot give a detailed statement to the lights on the ap.

    The customer said, that the AP wasn't also not working in another infrastruktur with a XG85w.

     

    It's an internal DHCP server on the XG.

    We already tried this :)

     

    I think the AP fails to boot in some way, thats why it always refreshes its dhcp link.

     

    Thanks for suggestions!

    Regards,

    Max
