1. Compatibility

Not all modems are compatible with Xfinity. Make sure to check the product details or Xfinity's website for a list of approved devices.

2. Speed

Consider the maximum speed the modem can handle. If you're paying for a high-speed internet plan, you'll want a modem that can keep up.

3. DOCSIS Standard

Data Over Cable Service Interface Specification (DOCSIS) is an international standard for transferring data over cable TV systems. A higher DOCSIS standard means faster speeds. For instance, DOCSIS3.1 is faster than DOCSIS3.0.

4. Built-in Wi-Fi Router

Some modems come with built-in Wi-Fi routers. This can be a cost-effective and space-saving option if you also need a router.
