Section 3 - Configuration
MAC address of the router is set to the MAC address of the WAN interface in the device. You can either type in an
alternate MAC address (for example, the MAC address of the router initially connected to the ISP) or copy the MAC
address of a PC. To copy the MAC address of the computer that initially connected to the ISP, connect to the router using
that computer and click the Clone Your PC's MAC Address button. The WAN port will then use the MAC address of
the network adapter in your computer.

When the the router detects that the WAN cable has been disconnected, it waits for "Link Drop Delay" seconds before
Link Drop Delay:
treating the WAN connection as broken. This delay allows you to temporarily remove the WAN cable without dropping
the logical connection to the ISP. It also allows for temporary electrical "glitches" in the physical connection. Values can
range from 0 to 65535 seconds. A value of zero causes immediate disconnection when the cable is pulled or when a
glitch occurs. Having to increase Link Drop Delay because you are experiencing WAN disconnections for long periods
would suggest a fault with the cable or with the modem (if any) to which it is connected.
