Spectrum generously includes top of the line internet modem free when you sign up for its internet plans. But if you prefer more control over your network, deeper performance insights, or simply want to use your own equipment, buying your own modem might be a smarter choice. In this guide, we’ll break down what kind of internet modems Spectrum supports and share some of the best options to consider:

How to Choose Your Own Modem for Spectrum Internet?

Before we dive into the list, you should know what features to look for when choosing a modem for your Spectrum Internet connection:

  • DOCSIS 3.1 Standard: The DOCSIS 3.0 standard modems are now outdated; Spectrum currently provides devices that support the DOCSIS 3.1 standard. This ensures minimum latency, better channel bonding, and better overall performance. Moreover, with DOCSIS 4.0 surfacing, having at least a DOCSIS 3.1compatible modem is essential to ensure forward compatibility and future-proof connectivity.
  • Matching the Ethernet Speed: The standard port of 1 GbE (Gigabit Ethernet) isn’t a strong choice for gigabit plans and will reduce the throughput. If you have subscribed to Spectrum’s gig speeds, then a 2.5 GbE port modem will be an optimal choice as it maximizes the overall performance.
  • Avoid Puma Chipset: Older modems carry Intel Puma chipsets, which are known for latency spikes, especially during high traffic periods. You can check out Spectrum’s modem list or find one on your own that doesn’t have a Puma Chipset.
  • Standalone or Combo: Spectrum offers WiFi 7 routers apart from their internet modem. Based on your network’s performance, you can decide if you want a standalone modem and router or a combo modem-router.
