The access point can also act as a client on a wireless LAN. When
configured as a client the access point functions in the capacity of a wireless
end station only. Communication through the wireless interface of the device
can only be accomplished using another Access Point functioning in AP
mode. When configured as a client, the access point connects to a single
computer or an Ethernet LAN via the Ethernet interface. An access point
configured to be a wireless client connected to a single computer is
