2702 AP Help

I've got a situation involving these access points and I'm looking to those with more knowledge and experience with these things to help me out.

Here's what the issue is: we just purchased 60 Cisco 2702 access points and I'm having difficulty with client computers maintaining connection. These access points are controlled by a Cisco 5508 that I just updated to 7.6.130.0, and I currently have 2 networks broadcasting, a public and an internal. My internal wireless network is 802.11x and authentication is controlled by a Microsoft NAP server using Active Directory. Everything works flawlessly with the 1141 and 1142 access points we have scattered throughout, but as soon as our laptops connect to the new 2702's the laptops begin saying "limited or no connectivity". This issue is only apparent on the RADIUS controlled network. If you connect the laptops to the public network (open network) they work just fine. I've restarted the RADIUS server just to see if that could possibly be the issue, but that doesn't seem to work.

One thing I haven't done that I still need to try tomorrow is connect a 2702 to a PoE switch and try it then. Right now in the 3 locations I've tested this, the switch is not PoE so I've been using a power adapter to power the AP. I've also tried plugging the CAT5 cable into the AUX port on the AP to see if the PoE port was causing grief (Using a PoE port with a power adapter?), and the AP would broadcast my networks but no device could connect.

I don't know if I'm missing something simple or what, but this is driving me up a wall. This issue appears to only be affecting the new 2702's. A slight headache to throw out there as well is we have no active maintenance agreement on the controller (SMARTNet lapsed a year ago). We are still waiting on a grant in order to order an HA controller, as well as a SMARTNet agreement that will give me the ability to get access to iOS updates (I had to pull some strings with a vendor just to get my hands on 7.6.130.0) in the event that it's a bug with my release and I need to update to 8.xxxxx.

Sorry for the wall of text, but I've just spent all day trying to trace this issue and I feel like I'm running around in circles. Any help you guys could provide would be greatly appreciated!
