Hi Guys,
Until recently I've never had any problems with the Always SSID, but tonight a remote site lost WAN connectivity causing the 3 AP68 RAPs to drop off the controller. For a while the client devices seemed to function OK, but after a while - I'm not sure how long at the moment, i think the APs must have stopped broadcasting because the clients couldn't connect and there was no evidence of them in the routers ARP table, although the APs were pingable so they were physically connected fine.
I'm just wondering if there's a logical explanation for this, could any other setting cause this to happen such as LMS Hold-down period or IPSEC retries or something like that?
When the WAN connection came back up, the APs reconnected instantly and the client devices were then working, there's nothing useful in the debug log, I'm guessing because that's live and not historic? I've captured a TS Log but can't see anything obvous in that.
*edit*
forgot to mention I'm using mixed WPA-TKIP and WPA2-AES.
Also just tried recreating the problem, the client maintains association after the connection to the controller is lost, but if I reboot the AP and it's unable to route to the controller, the SSID is broadcast but it seems to fail to authenticate.
I'm in the process of testing with just WPA-TKIP now ......... which also seems to fail to authenticate after reboot while the RAP is offline.
I'm certain I have tested this in the past without any problems!
The SSID is definately set to Always so I'm not sure what or why this would have happened!
*Edit*
Oh and my hardware is M3 / AP68/93 as RAP, 5.0.4.3
