A sticker on your modem router displays the preset WiFi network name (SSID) and network key (password).

Install using the modem router web interface

Before you begin:

• Collect your cable Internet service provider (ISP) account information: mobile phone number, username, password, and account number.
• Collect modem router information: Model number (C3700v2), MAC address, and serial number from the modem router label.
• If using Xfinity, download the Xfinity app from the App Store or Google Play™. Ensure it's updated to the latest version.

Connect your modem router

1. Turn off and disconnect existing modems and routers. If replacing a modem, unplug it and plug the new modem router into the same outlet.
2. Connect a coaxial cable from the modem router's coaxial connector to the cable wall outlet. Ensure it is tightly connected. (Recommendation: Connect directly to the wall outlet. If sharing, use a 3.5dB (1 to 2) splitter.)
3. Connect the power adapter to the modem router and plug it into an electrical outlet. The startup procedure takes about one minute. The Power LED should light solid green. If not, check the Power On/Off switch on the back panel.
4. Wait for the Online LED to light solid green. This process may take up to ten minutes. The Online LED stops blinking and lights solid green for at least a minute when the cable modem is online.

Set up and activate your modem router with Xfinity

1. If your current modem is leased from Xfinity, call Xfinity support to remove it from your service.
2. Ensure your mobile device uses an LTE Internet connection (do not connect to WiFi).
3. Open the Xfinity app and sign in with your Xfinity ID.
4. Follow the on-screen steps to get online. The activation process takes about five minutes.
5. On your mobile device, launch a web browser and enter routerlogin.net or 192.168.0.1.
6. Follow the prompts to agree to terms, change admin credentials, set up security questions, and review WiFi network name and password.

Set up your modem router with another cable Internet service provider

1. Connect your computer or mobile device to the modem router via WiFi or Ethernet:
   • WiFi: Use the WiFi network name (SSID) and password from the modem router label.
   • Ethernet: Use an Ethernet cable to connect a computer to an Ethernet port on the modem router (computer must have an Ethernet port).
2. Launch a web browser and enter routerlogin.net or 192.168.0.1.
3. Follow the prompts to agree to terms, change admin credentials, set up security questions, and review WiFi network name and password.

When the Basic Home page displays, you are ready to activate your Internet service. Contact your cable Internet service provider.
