Sparklight Supported DOCSIS 3.1 and 3.0 Cable Modems

Below are all the modems that Sparklight has approved for their residential customers to purchase and use on their network, as of November 2023. Sparklight lists them on their website here: Sparklight Supported Modems List. Prices below are updated every hour. We’ve gone through all of them to find the ones that can be bought at Amazon, Best Buy, or Walmart.

If you’re paying $10.50 a month to rent a modem from Sparklight, that’s $126 a year, or $630 over 5 years. You can buy a new one that will pay for itself in less than six months.

Sparklight Business Customers: See our Sparklight Approved Modems for Business page for supported modems.
Sparklight Phone Customers and WiFi ONE subscribers can only use modems leased from Sparklight.

Easy to install. Just hook up the modem and call Sparklight to register your modem. Read more at Sparklight here: Connect a Sparklight Modem

If you need further help with your decision or understanding some of the terms, see our Cable Modem Buying Guide.

Select your Sparklight speed plan below. If it’s not listed, choose a plan that’s higher than your current one. This will allow you to get the maximum speed out of your plan. If you want to future-proof your purchase, as speed plans inevitably increase, we and Sparklight suggest selecting DOCSIS 3.1 from the DOCSIS menu below.
