Has anyone else seen this? We're running an Aruba 6000 series controller with 40 RAPs associated. Starting 4 days ago, our folks at those remote sites began recieving a message on their laptops showing our internal network as being unauthenticated. This happens approx 15 mins after connecting - for the 1st 15 mins they are fine. The same issue is also happening to our Guest network at these sites. The guest network is set with a WPA2 passphrase, and the Internal network is using radius pointed back at an internal server that is also handling dhcp for the internal users. the Guest users pull their dhcp from the controller itself.
Also - any devices physically connected to the RAP is having issues as well ( mainly printers).
Nearly all of our sites are running IAP-205Hs that were converted to RAPs, and a few older 155s are out there.
Thanks!
