While renting your modem and other networking equipment can be very convenient and save time in the short term, you will be charged a monthly rental fee for your modem on your service bill. That $10 per month charge definitely adds up!

With most carriers, finding the right model for your service can be tricky. Thankfully, Optimum has only allowed a couple models on their network for some time now, making the selection process much easier. Our Optimum approved modems list features models that are on the official list, as well as models that have been tested to meet Optimums requirements AND have been successfully activated recently by our customers.

    How to Activate Your Modem with Optimum Cable

    Activating your modem with Optimum is super quick and easy. You’ll need to set aside around 30 minutes for most activations to ensure you’re not feeling rushed.

    1. Plug in your modem to the power supply cable, then plug the power supply cable into the wall.
    2. Plug the coaxial cable into the wall, and then screw the other end into the coaxial port on the back of the modem.
    3. Wait 5 minutes for your modem to fully boot up. If your modem has built-in wireless, you’ll know your device is fully powered on once the wireless lights come on.
    4. Connect an ethernet cable into the back of your modem and then plug in the other end into your computer.
    5. Open a web browser (such as Chrome, Firefox or Safari) and type install.optimum.com into the URL web address bar at the top of the screen, then hit enter.
    6. To activate your modem you’ll need your 13-digit account number to register online, which you can find on your Optimum bill, a receipt from the Optimum store as well as several other places.
    7. Follow the on-screen steps to set up and activate your new modem.
    8. After set up is complete, you can now disconnect the ethernet cable from your computer or laptop and connect it into a wireless router if you’re using one for your wireless service.
