DIR-120 Ethernet Broadband Router

DHCP Connection Settings

Setup Wizard – Configure Dynamic IP Address Connection

For Dynamic IP Address connections, you may want to copy the MAC address of your Ethernet adapter to the Router. Some ISPs use the unique MAC address of your
computer’s Ethernet adapter for identification and for IP address assignment (DHCP) when you first access their network. This can prevent the Router (which has a different
MAC address) from being allowed access to the ISP’s network (and the Internet). To clone the MAC address of your computer’s Ethernet adapter, click the Clone MAC
Address button. Click Next to continue.

Host Name

The Host Name is optional but may be required by some ISPs.

MAC

If you clone the MAC address of your computer to the Router, the MAC
address will appear here. This will be the MAC address recorded by the
ISP’s server when the connection is initiated.

Clone MAC Address

The default MAC address is set to the Internet’s physical interface MAC
address on the Broadband Router. You can use the “Clone Your PC’s MAC
Address” button to copy the MAC address your computer’s Ethernet Card to
the Router.
