Sean, Glad to hear it. I had the same run around between switching and wireless tac cases and remember it was painful to say the lease.

Hi Everyone, This is a question for all of those out there that are using Cisco 702W wall mounted access points hooked up to a Cisco Catalyst 2960x, 48 port switch (WS-C2960X-48FPD-L).

The majority are connected to 29060x switches, running 15.2(2)E6. this is where we have a problem. Almost all of those connected to 2960x keep dropping link, these bounces vary in recovery time, sometimes as shown below the recovery is under 10 seconds, sometimes over 10 seconds. The latter generates an alert from my 5520 WLC which is caught by Prime Infrastructure and I get notified. We have yet to see the same issue with the 702Ws that are connected to our 3750x switches.
