All Charter Compatible DOCSIS 3.0 Internet Modems

Modem list updated September 2017. Prices updated every hour.

(If you're in a former Time Warner/Bright House area and have Spectrum internet, go here to find modems: Time Warner Approved Modems.)

Below are all the modems on the Charter Approved Modems List and that can be bought at Amazon, Walmart or Best Buy. We've gone through all of them to find the ones that can be purchased at major retailers.

Note the following policy from Charter: Effective July 26, 2012 For new Internet Customers and customers switching to our New Package Pricing, we will no longer allow customer-owned modems on our network. In order to provide our customers powerful and reliable Internet service at a great value, we will provide modems included in Internet pricing under our New Package Pricing. This notice can be found here near the top of the page under "Compliant Modems": Charter Policy on Customer Owned Modems for New Internet Customers and Customers Switching to New Package Pricing

Easy to install. Just hookup modem, open browser window on attached computer and follow the on-screen instructions.


DOCSIS 3.0 Cable Modems

Cable Modem Buying Tips and FAQ's

All Charter Spectrum Internet Service subscribers, buy any of these DOCSIS 3.0 modems. If you subscribe to service over 60 Mbps, choose a modem with 8 down channels to maximize your speed. For plans over 100 Mbps, buy one with at least 16 down channels. If you have telephone service with Charter too, these won't work.

There are two tables on this page. The top one contains all Charter recommended modems. The second one contains Minimally Qualified Modems. Charter says on their Charter Approved Modems List page: "You may also choose to buy a modem that has passed minimal testing to confirm that it won't cause harm to our network. Though permitted for use on our network, we recommend against using Minimally Qualified Modems because they haven't been tested to confirm their ability to deliver your purchased internet service speed."

You can click on any column header to sort that column. Also, you can narrow down your search by typing in the search box. For example, if you want to see only modems with Wifi-AC routers, type "ac" in the search box. Clicking on any price takes you to the retailer.
