(MAC) Address
All network components including cards, adapters, and routers, have
a unique "serial number" called a MAC address. Your Internet Service
Provider (ISP) may record the MAC address of your computer's
adapter and only let that particular computer connect to the Internet
service. When you install the Router, its own MAC address will be
"seen" by the ISP and may cause the connection not to work. Belkin
has provided the ability to clone (copy) the MAC address of the
computer into the Router. This MAC address, in turn, will be seen
by the ISP's system as the original MAC address and will allow the
connection to work. If you are not sure whether your ISP needs to
see the original MAC address, simply clone the MAC address of the
computer that was originally connected to the modem. Cloning the
address will not cause any problems with your network.
