How do I install my DCM-301 modem?

Note: Remember to contact your Internet Service Provider (ISP) to register the MAC address of the DCM-301 or you will NOT be able to connect to the Internet.


The following instructions are for users with a router.


Step 1: Power off your router.


Step 2: If you are replacing the modem, disconnect all cables and unplug the power to your old modem.


Step 3: Connect the coaxial cable from your wall to the cable modem’s CATV cable connector. If you plan to have the cable connected to a television as well as the cable modem, you must use a cable line splitter (not included).


Step 4: Plug the cable modem’s power adapter into a wall outlet or surge protector and into the cable modem’s power port.


Step 5: Plug one end of the Ethernet cable into the cable modem’s Ethernet port and the other end of the cable into the WAN or Internet port on your router.


Step 6: In most cases you will have to call your cable company (Internet Provider) and register the MAC address of the D-Link modem. The MAC address is on a label on the bottom of the modem.


Step 7: When the modem is working properly, the Power, DS, US, Online, and LAN LEDs will all be lit.
