Sparklight Approved Modems

The recommended Sparklight approved modems appear below. With several certified modems for Sparklight internet services, a couple of devices are top picks.

If you need telephone service, cable phone modems must be rented from Sparklight to work properly for phone service.

Read the Cable Modem Buying Guide to help you choose a modem. Do not forget to purchase your modem accessories.

Internet providers have begun removing some DOCSIS 3.0 modems from their networks. To maximize the years of use from a modem, it is strongly recommended to purchase a DOCSIS 3.1 device (the latest standard).
