Cable Your Modem Router to a Router or Gateway
If you want to cable the modem router to a router or gateway, you must log in to the modem
router and change its Router Mode setting. Changing this setting prevents certain network
conflicts that can occur when two devices on the same network perform routing functions
such as network address translation (NAT) and DHCP (assigning IP addresses to devices on
the network).
To cable your modem router to a gateway or router:
1. Connect the antennas to the threaded antenna posts.
2. Turn off existing modems and routers.
If you are replacing a modem that is currently connected in your home, unplug the
modem and plug the new modem router into the same outlet.
3. Connect a coaxial cable.
Use the coaxial cable that is provided by your cable company to connect the cable port
on the modem router to a cable wall outlet.
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.
Make sure that the cable is tightly connected.
4. Connect the power adapter to the modem router and plug the power adapter into an
electrical outlet.
Make sure that the Power On/Off button and the LED On-Off switch on the rear panel of
the modem router are in the On position.
The startup procedure takes about one minute. When the startup procedure is complete,
the Power LED lights green.
5. On your WiFi-enabled computer or mobile device, find and select the WiFi network.
The WiFi network name is on the modem router label.
6. Join the WiFi network and enter the WiFi password.
The password is on the modem router label.
Your WiFi device connects to the WiFi network.
7. Launch a web browser.
8. Type http://routerlogin.net or http://192.168.0.1.
A login window opens.
9. Enter the modem router user name and password.
The user name is admin. The default password is password. The user name and
password are case-sensitive.
