I've a Cisco WLC 4402, 16 AP(1000 series, 1120 series 1130 series), 6 WLANS, 30 Clients. All works fine but I've a little problem with DHCP assignment: if I connect a notebook through its wireless network card I can retrieve an IP address and all is ok. If I connect the notebook through an Ethernet Bridge (like Linksys Ethernet Bridge WET54G V 3.1) I must assign a static Ip to my notebook to have connectivity.
Note that Ethernet Bridge use the same credentials used on notebook wireless card and the bridge is able to obtain a dynamic Ip from WLC.
Why the notebook can't retrieve a Ip address if it is connected through an Ethernet bridge?
