AP and 1 of 2 STAs "show" Offline/Online every 4 hours

Hi All:

 

AC2 chart keeps showing AP going offline, then online one minute later, every four hours.

 

About 3 mintes later, one of two of its stations then shows offline, then online one minute later, every four hours. 

 

Logfiles are shown below for affected AP and STA.   

 

Have been through both STAs and these appear to be are configured identically.

 

Any idea what this is and how to fix it?

Hi @intermod,

 

check if there is another device in AC2 with the same IP address. Remove one tof he devices if that's the case. It is possible that reconnect scheduler toggles between one and another while reconnecting.

Thanks - will check this.  One of the offfenders just went down due to power outage so I must wait until it recovers.

No conflicts found.  We only have 3 devices on this subsystem so its easy to verify.      

 

I also deleted the offending AP and STA and re-entered.  Slight changes occurred in the time between Offline and Online, but same basic problem.

 

Problem persists.
