I have a problem with a 2106 WLAN Contoller.
The clients can connect and associate to the WLAN and get their IP details via DHCP from the internal DHCP server. However, only 2 clients can get out through the gateway at any one time. All other clients that connect will get their DHCP addresses(that match the config of the 1st 2 clients), but they cannot get to the gateway. They can ping any client on the WLAN and the controller.
