A List of Approved Modems and Routers for Spectrum, Comcast Xfinity, Cox, Optimum, Suddenlink, & More

If you’re wondering, “Will my modem work with my new Internet plan?” or “Will my router work with my new ISP?”, the short answer is Yes — so long as you check for compatibility.

While you could go with your ISP’s modem and router rental service, many consumers want the opportunity to choose a modem and router themselves. Taking on the responsibility of choosing your own router and modem has many advantages, from saving money to improving connectivity and Internet speed in your home.

However, choosing a modem and router that is approved for and works well with your ISP is essential to success should you choose to forego ISP-provided hardware. In general, the most important thing to weigh is whether or not your modem is compatible with your provider — a router just needs to be compatible with your modem. Here is a list of some of the more popular and highly rated approved routers and modems for some of the most popular and highly rated Internet service providers.
