Automatic discovery - Select this to have the Wireless ADSL
Router contact the PC and find its MAC address. This is only poss-
ible if the PC is connected to the LAN and powered On.
MAC address is - Enter the MAC address on the PC. The MAC
address is also called the "Hardware Address", "Physical Address",
or "Network Adapter Address". The Wireless ADSL Router uses
this to provide a unique identifier for each PC. Because of this, the
MAC address can NOT be left blank.
Add a new PC to the list, using the data in the "Properties" box.
If "Automatic discovery" (for MAC address) is selected, the PC will be
sent a "ping" to determine its hardware address. This will fail unless the
PC is connected to the LAN, and powered on.
