[Clarification 1/15/2018: This list only covers customer-owned modems approved by Charter Communications. It is not a comprehensive list of modems that may have been supplied directly by Charter/Spectrum, or its predecessors Time Warner Cable or Bright House Networks, which are obviously also acceptable. However, if you have a modem supplied by Time Warner or Bright House, it might not support the upgraded faster speeds Spectrum now offers. You might want to contact customer service to verify whether your current modem is capable of performing at the speeds now provided.]
Charter Communications recently increased broadband speeds for most of their customers, and many cable modems that are still in use from the days of Time Warner Cable and Bright House Networks cannot support the company’s fastest speed tiers. As a result, Charter has updated their approved/recommended cable modem list to help customers obtain a modem that can support faster speeds.
Those customers who have moved away from a legacy Time Warner Cable or Bright House internet plan can get a free cable modem from a local Spectrum cable store. If you prefer to still own your own, here is the updated listing. We recommend choosing a model capable of supporting up to 300 Mbps speed because additional speed upgrades are likely in the future. Most customers now receive at least 100 Mbps service, so at least choose a model that can support that speed.
Gigabit (940 Mbps) Tier
At this time there are no modems that have passed certification testing for the Spectrum Internet 1 Gig speed tier (940Mbps). You need to use a cable modem supplied by Charter/Spectrum.

This can’t be all the approved modems.
They only just recently gave me a Ubee DVW32CB for my 300mbit service.
Why would they themselves give me a modem that’s not on their own recommended list?
I concur with Nick that there’s no way in that this is the list of all approved modems. In fact, when I click on the link provided in Mr. Dampier’s original posting, the underlying page source apparently geo-locates where I’m connecting from, and instead of displaying the approved modem list, it almost immediately redirects to the TWC version of the Spectrum website. Also, I was just in my local cable modem office this month to see which cable modem they have to give to customers and it is a brand that isn’t even on this list, and as I recall… Read more »
Charter has not fully converted former Time Warner Cable customers to its legacy Charter website and support platform, which is why TWC customers entering zip codes for TWC service areas are still diverted to Time Warner’s website for now. While there are older modems still in use across Charter/TWC/BH’s service area, Charter reserves the right not to activate customer-owned modems that are not on its approved list when the last vestiges of the TWC brand and website disappear sometime this year. We’ve encountered readers who signed up for service and have run into activation problems for modems not on the… Read more »
use this list too
the ubee is on this list under Modems offered by Spectrum

Folks, I should have been more clear that this list is for approved CUSTOMER-OWNED modems for Charter/Spectrum customers. It does not include modems supplied by Charter itself (or those approved by either predecessor Time Warner Cable or Bright House Networks). I will make an update to clear that up.
Obviously if Charter gives you a modem, it is approved. 🙂
Does Spectrum support Arris Surfboard SBG6782-AC?
