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

strip and seated in the power port.

Internet (veried by your Internet provider) and you are connected to a
router, you may have to reset and recongure your router.
