Learn > Cable Modem & Routers > What Modems Work with Xfinity? (And How to Choose the Right One)

Yes, you can use your own modem with Xfinity—as long as it’s compatible with their network. To avoid rental fees and get faster speeds, choose a DOCSIS 3.1 cable modem that is certified by Xfinity. Hitron’s CODA and CODA56 modems are reliable, high-performance options for Xfinity customers.

 

What to Know Before You Buy a Modem for Xfinity

When people search for “modem for Xfinity,” they’re often looking to stop paying rental fees, improve their speeds, or avoid compatibility issues. This guide gives you everything you need to choose the right modem—and skip the guesswork.

 

What Makes a Modem Compatible with Xfinity?

Xfinity (by Comcast) requires that any modem you use on their network meets certain standards:

  • DOCSIS 3.0 or DOCSIS 3.1 technology (DOCSIS 3.1 is recommended)
  • Approved through Xfinity’s certification process
  • Listed on the Xfinity compatible devices page

If the modem is not on that list, it may not activate on their network—even if it works technically.

 

Why DOCSIS 3.1 Modems Are Better for Xfinity

DOCSIS 3.1 is the latest standard for cable Internet. It delivers:

  • Faster download/upload speeds
  • Better performance with multiple connected devices
  • Future-proof support for Xfinity’s Gigabit and higher-tier plans

If you’re upgrading or purchasing a modem today, DOCSIS 3.1 is the right choice.

 

Avoiding Xfinity’s Monthly Equipment Fees

When you rent a modem from Xfinity, you’re often paying $14–$15 per month. That’s over $180 per year.

Buying your own compatible modem means:

  • No more monthly fees
  • Full control of your network hardware
  • The ability to upgrade on your own terms

How to Set Up a Modem with Xfinity

  1. Connect your new modem to a coaxial cable and power source
  2. Wait for the modem lights to stabilize
  3. Go to xfinity.com/activate from any connected device
  4. Follow the on-screen instructions to complete activation
