I have a wireless network with an 1131AG in one building and a 2106 controller in my hub. The 1131 AP registers with the 2106 and I am using ACS as a RADIUS server for authentication, again no issues. My end clients are Dell laptops running the integrated Intel wireless cards. I can build a profile (WPA2+802.1x+LEAP) and the client will associate and authenticate. My problem is I dot grab an address from the DHCP pool running on my core 3750 switch. If I hardcode and IP address on the laptop I still cant ping anything on the 3750. If I modify the WLAN profile to the Management interface (instead of a user vlan) then I can get an address and I can surf out just fine. This is basic setup and it worked just fine in the lab. I am bridging (with 1310's) between the buildings since they are fairly far way from each other but I can access all vlans on the switch in my new building. I've included a drawing...any help would be appreciated.
