To cable your modem router:
1. Connect a coaxial cable from the cable port on the modem router
to a cable wall outlet
or a line splitter.
Use the coaxial cable that your cable company provides.
Note: If Charter is your cable Internet service provider (ISP), Charter
recommends connecting your modem router directly to a cable wall
outlet. If you must use a splitter, use a splitter that is rated at 3.5 dBmv.
2. Connect the power adapter to the modem router and plug the power adapter into an
electrical outlet.
3. Press the Power On/Off button on the rear panel of the modem router.
The Power LED lights green.
You can log in to the modem router
to view or change its settings.
Cable Your Modem Router to a Router
If you want to cable the modem router to a router, you must log in to the modem router and
change its Router Mode setting. Selecting the No check box for Router Mode prevents
network conflicts. Problems can occur when two routers on the same network both attempt to
perform routing tasks such as Network Address Translation (NAT) and DHCP (assigning IP
addresses to devices on the network).
