Connecting the Cable Modem (with 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.

Troubleshooting

1. Power LED is not on.

•  Verify the power adapter is plugged into a working outlet or power 

strip and seated in the power port.

•  Press the power button on the back of the modem.

2. Cannot connect to the Internet.

•  You must contact your Internet provider and register the MAC address 

of the modem (located on the bottom of the modem). If you skip this 

step you will not be able to connect.

•  Verify all cables are connected properly.
•  If the LEDs on the modem are indicating that you are connected to the 

Internet (verified by your Internet provider) and you are connected to a 

router, you may have to reset and reconfigure your router.
