Client List Screen

The Wireless Client List provides details on the devices that are connected
to the Wireless LAN. The list is only created when Wireless Networking is
enabled. For each device that is connected to the Wireless LAN, the MAC
address and Connection Speed of that device is displayed. As you
connect more devices to the Wireless LAN, the client list will grow to a
maximum of 32 (the maximum number of wireless devices that the
Gateway can support).
