How to Choose a Gaming Modem

  • DOCSIS 3.1: This standard supports gigabit-plus plans and is the baseline for future-proof gaming performance.
  • Provider compatibility: Confirm the modem is approved for your ISP, whether Xfinity, Spectrum, Cox, or another.
  • Multi-gig port: A 2.5Gbps Ethernet port lets fast plans reach your router or gaming PC unbottlenecked.
  • Plan speed match: Choose a modem rated at or above your plan’s top speed to avoid limiting throughput.
  • Modem vs. combo: A standalone modem paired with a good gaming router usually beats an all-in-one for control.
