Having the right modem and router can make all the difference when it comes to internet speed and connection strength throughout your home.

For Spectrum internet customers, a network-approved modem is already covered and included with your plan. However, you do have the option to purchase your own. Additionally, you must either rent a pre-configured Wi-Fi router from Spectrum for a monthly fee or use your own.

When choosing whether to buy your own modem, it’s important to make sure whatever you pick is compatible with your Spectrum internet service.

Top Spectrum-compatible modems

Spectrum-compatible modems are authorized for specific speed tiers. Check your original plan agreement to find out what tier you’re paying for then view the approved modems below. Some of the modems on this list, like the Netgear C6250, are actually modem-router combos, which means you can get away with just one device.

Using a modem or router that’s not authorized for your speed tier could result in slower internet speeds or a weaker connection.

Using your own router for Spectrum Wi-Fi

Spectrum doesn’t maintain a list of network-approved routers and they won’t provide technical support to any router you purchase yourself. However, they do provide a few recommendations:

  • Router should be a draft 802.11N router with a built-in gigabit switch
  • Router should have concurrent dual-band wireless-AC connections for households with heady internet usage

Additionally, you’ll want to make sure that whatever router you choose is compatible with your modem and speed tier to ensure you’re getting the speed you’re paying for at home.
