Charter Spectrum Updates Approved Modem List for New Speed Tiers

Phillip Dampier January 11, 2018 Broadband Speed, Charter Spectrum, Consumer News 6 Comments

[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 »
