Supported Cable Modems - Residential Only
Sparklight strives to produce a high level of reliability, stability, and security for our high-speed Internet subscribers. As such, we continually evaluate cable modems on our network for compatibility and performance. The following is an up-to-date list of cable modems that have been certified to work on the Sparklight high-speed Internet network.
Note: If you are a business customer, please reference our approved business modems page HERE.
Sparklight requires customers to use a DOCSIS 3.0 Cable Modem. These modems incorporate the latest cable technology, can deliver faster Internet speeds, and have a longer expected lifetime. Existing customers with older modems, using DOCSIS 2.0 technology, will still be able to utilize some Sparklight high-speed Internet packages, but will not be able to utilize the faster high-speed Internet packages without first replacing their modem. Sparklight strongly recommends customers select DOCSIS 3.0 modems for the best speed performance.
Note: GigaONE service requires the use of an approved GigaONE modem.
Note: WiFi ONE service requires the use of a leased modem through Sparklight. Customers will not be able to use their own modem with WiFi ONE service.
- Modems recommended for plans up to 1000 Mbps.

What does "End of Life" mean for my modem?
A cable modem that is specified as "End of Life" was once a recommended Sparklight cable modem. Due to the discontinued production, manufacturer support changes, or other technical issues, these cable modems are no longer recommended. At present, these modems will continue to operate normally on our network and are permitted. No dates have been specified to retire these modems from our network at this time.
If you lease a modem from Sparklight, you don't need to do anything at this time. You will be contacted by a representative from our local Sparklight office soon. Until then, please continue to enjoy your high-speed Internet access provided by Sparklight!
If you have purchased your own modem, we suggest that you replace the cable modem with an approved Sparklight modem in the near future.
Want to purchase your own modem?
If you choose to purchase a modem, Sparklight recommends you purchase a new modem with DOCSIS 3.0 capability from a reputable source. Second-hand modems may not work properly on Sparklight's network even if listed above. Sparklight reserves the right to refuse service to any modem or modem model which might impair network performance. See the Acceptable Use Policy (AUP) for details.
