I'm trying to troubleshoot a pretty baffling issue at the moment. For the last few months, we've seen a problem where client laptops waking from sleep will get an IP address, show full connectivity, but be unable to browse the Internet or other network resrouces. Somewhere between 2 and 15 minutes later, full connectivty is restored for no appearent reason. The problem has gotten prgressively worse in the last several days.
This is occuring on multiple SSIDs, different AP groups, different subnets, etc. All APs are 802.11n, all SSIDs are set to use WPA2 with AES. Controller is running 6.3.13. We are doing some mac address authentication with Clearpass on one SSID, but the problem occurs elsewhere as well. Looking at the firewall logs on the controller, pings leave the client machine, I can see the response being returned to the client, but the client never receives the response or any other network traffic. The problem occurs on Mac and Windows, and virtually every OS we run.
Any thoughts or ideas would be greatly appreciated.
