Hi. Interesting problem. Have AP1200 with 12.2(15)JA1 and dual radio (.a and .b). Auth is with a Cisco ACS 3.2(3), Windows Domain, LEAP and one SSID on a single VLAN. I can always associate with both radios, .a and .b, HOWEVER I can never receive an IP address on my .a radios. I have to disable my .a radio and only prefer .b to get an IP address. Shows as 0.0.0.0 on the AP. Has anyone seen this before? Same thing with both Cisco .a card and Dell Truemobile 1400. TIA!
