Step by step

  1. 2 min

    Confirm compatibility with your service provider

    Visit your ISP’s official website and locate their approved modem list. Input your specific service plan speed to ensure the hardware supports your tier, particularly if you have Gigabit speeds requiring DOCSIS 3.1 hardware.

    Note: Avoid purchasing used modems that may still be registered to a previous owner’s account.

    Purchase a DOCSIS 3.1 modem and separate router

    Purchase a dedicated modem that matches your ISP’s requirements. Separate your networking needs by choosing a dedicated Wi-Fi router, which provides better performance and future-proofing than integrated gateway units.

    Note: Look for modems marked 'ISP Certified' to ensure seamless activation.

    Swap the physical hardware

    Disconnect the coaxial cable from your existing rental unit and attach it to the new modem. Connect the modem to your new router using a Cat6 Ethernet cable, then power both units on and wait for the lights to stabilize.

    Note: Do not return your old equipment until your new setup is fully functional and verified.

    Register the device with your ISP

    Use the ISP’s self-activation portal via a mobile device on cellular data or by calling the provider’s activation line. You will need the HFC MAC address or CM MAC address printed on the label of your new modem to authorize the equipment on their network.

    Note: Have your account number ready for the automated activation system.

    Set up your private Wi-Fi network

    Connect your computer to the router's default SSID using the credentials provided on the router's base sticker. Navigate to the router's configuration IP address (typically 192.168.1.1) to change the default Wi-Fi network name and create a strong, unique WPA3 password.

    Note: Update the router firmware immediately after initial configuration.

    Return the ISP equipment

    Take the ISP-provided unit to an official retail store or shipping drop-off point as directed by your provider. Request a return receipt or tracking number and keep it for your records to ensure the monthly rental charges are permanently removed from your billing statement.

    Note: Failure to obtain a receipt may result in unreturned equipment fees.
