  1. Turn off and disconnect existing modems and routers.

  2. Connect a coaxial cable.
    Use a coaxial cable to connect the cable port on the modem router to a cable wall outlet. Make sure that the cable is tightly connected. We recommend that you connect your cable modem directly to a cable wall outlet.
    If you must share the connection, use a 3.5dB (1 to 2) splitter.

  3. Connect the power adapter.
    Connect the power adapter to the modem router and plug the power adapter into a power outlet.

  4. Wait for the Online LED to light solid white.
    This process might take up to 10 minutes. When the cable modem comes online, the Online LED stops blinking and lights solid white for at least a minute.
    After 10 minutes, if the Online LED doesn’t light solid, make sure that the cable outlet is working, or call your Internet service provider (ISP) to make sure you have service.
    Note: When the Online LED lights solid, your modem router is not connected to the Internet yet. You must connect a router or computer to your cable modem, and then activate your cable modem with your cable Internet provider.

  5. Connect your computer or mobile device to the modem router with WiFi or Ethernet. NETGEAR-CAX25-AC2400-WI-Fi-Cable-Modem-Router-5

    • WiFi. Use the WiFi network name (SSID) and password on the product label to connect.
    • Ethernet. The computer must have an Ethernet port. Connect an Ethernet cable to an Ethernet port on the modem router and the Ethernet port on your computer.
  6. Collect the following information:

    •  Your cable Internet provider (ISP) account information
    • Cable modem model number, which is CAX25
    • Cable modem serial number
    • Cable modem MAC address
  7. Activate your Internet service:
