I think it's safe to say that the aforementioned guy locked away in the dark room without food or water is in a better place now. So with more new APs, features like 3G and 802.11ac, and even an 8500 controller in the midst; there's still no sign of...
I recommend running autonomous with WDS seemed to be seamless on hand offs from AP to AP when running EAP-TLS and IAS sever. Wish I would have stayed away from LWAPP and controllers for I lost the seamless roaming on the change over.
Even running open authentication on the AP's I lose 3-12 pings before my laptop will switch to the new AP. This will be a problem when we implement IP phones on the wlan. TAC didn't have an answer for this issue.
When using only a 2000 or 4400 controller without the location appliance the client is place on the map next to the AP it is associated with and not at the location the client actually was on the map. This was not how the product was sold to us.
