If You Want to Connect a Router
Most users will connect a WiFi router to the MB7621. A
wireless router lets multiple devices (computers,
smartphones, tablets, video devices, game stations…) share
your cable modem’s Internet connection, either wirelessly
or through a direct Ethernet connection. Connecting a
router to the MB7621 may be made initially, before
activating the cable modem, or it may be done after the
cable modem has been activated from a PC.
1. The cable modem and the router should both be
powered off.
2. Plug one end of the cable modem’s Ethernet cable into
the Ethernet jack of your modem, and plug the other
end of the cable into the router’s WAN port. (You may
need to disconnect the cable from your computer first.)
3. Power-up the cable modem. Wait for the ONLINE light
( ) to be solidly lit.
4. Power-up the router. Wait for the router to complete its
power-up sequence.
5. The LAN light on your modem should be lit to show
the Ethernet connection to your router.
6. Follow your router’s instructions for setting up the
router and connected devices.
If you haven’t already activated your Internet service, do
that now. (See Prepare to Activate on page 5.) Using a
computer or other device connected to the router, try
connecting to the Internet. If it works, Congratulations!
Installation is complete.
