Buy A Time Warner / Bright House / Spectrum
Approved Cable Modem

A guide to finding a modem that works with your Internet Service

Time Warner / Bright House / Spectrum Compatible Modems

Modem list updated September 2017. Prices updated every hour.

Charter has now bought Time Warner and Bright House TV and internet businesses and is beginning the process of rebranding it Spectrum. You can still buy your own modems. (If you're not in a former Time Warner/Bright House area and have Spectrum internet, go here to find modems: Charter Approved Modems.)

Below are the most popular modems on the Time Warner/Spectrum Approved Modem 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. (See Bright House Approved Modem List - Same as Time Warner)

If you're paying $10 a month to rent a modem from Time Warner or Bright House, that's $120 a year or $600 over 5 years. You can buy a new one that will pay for itself in less than one year.

Easy to install. Just call your internet company and give them the Cable Modem ID (MAC address) and drop off your old leased modem with them. (Instructions for finding your MAC Address)

Note: If you have Time Warner phone service, you can buy one of these modems for internet service. You then keep your old Time Warner modem for phone service, and Time Warner will not charge you for rental fees. Here's a helpful link on Time Warner's site: Instructions for connecting 2 modems (Scroll down to "Activate a purchased modem - Internet & TWC Phone Customer" and then click on "Set up and activate your modem".) Basically you just need a splitter to run one cable to your phone modem and one to your new internet modem.

Cable Modem Buying Tips and FAQ's

Time Warner, Bright House, Road Runner or Spectrum customers who subscribe to Turbo, Extreme or Ultimate Internet Service or others who want to upgrade to faster services in the future, buy any of these DOCSIS 3.0 modems (Ultimate 300 subscribers should buy the ARRIS / Motorola SB6183, SB6190, SB6900AC or the Netgear C6300).

All of these modems are high quality and have pretty much the same features, except for number of download channels and those with routers built in.

I learned this the hard way and no one believes me. I have the SBG6580 which works fine but it must be purchased BRAND NEW. You cannot get a USED router. It will not work. I have 2 of them that I got cheap on ebay but they told me once they are configured that's it. you cannot reset it as a new unit.

I have Spectrum and want to buy a new modem and router instead of renting one from them for 10 dollars a month. I would like a router that updates its firmware automatic. Any suggestions. Thanks

If you are buying a router/cable modem combo you will have to trust your isp to update your device as you will not be able to control it. You are better off buying these device separately if you are concerned about security as the isp's have shown they do not give a damn if your router gets hacked and the router poses a bigger threat to you than the cable modem.

I have 2 4K TV, 2 more smart TV currently use the Cisco DCP3216 modem with a Linksys EA8500 Router. When streaming movies and using a computer the movie will sometimes stop and the internet on the computer slows down. We are with Spectrum- Charter and were at down load speed 60 but just went up to 100 and are having the same problem. I am looking into getting a TP-Link AC1750 Archer CR700, or TP-link AC1900 CR1900 modem/router but charter says these are not that good. What would be your recommendation.

There are no modems without a wifi router that has more than one ethernet port. Don't know if this would work for you, but you can buy a wired router (no wifi) with multiple ethernet ports and plug that into the modem. Here's one for around $20 at Amazon: TRENDnet 4-port router

No, you can't buy an eMTA for Brighthouse. I think you can still buy a non-eMTA modem and use the Brighthouse supplied modem for your telephone. Brighthouse won't charge you for the telephone modem. Read the note "If you have Time Warner phone service" at top of this page.

I that at some point TW/Comcast will phase out the Ambit DOCSIS 2.0 but that's what is hooked up to my laptop now and my son has a spare (new.same U10CO18 DOCSIS 2.0)Ubee that would save me $10 a month. I'm assuming that: even tho TW doesn't recommend this model I should be able to get them to register it if it duplicates what I now have

I bought the Netgear Nighthawk Modem and router all in one and it is so future proof. With 24x8 ability and the auto 2.4Ghs and 5Ghz my 2 wired computers are running at 2.4(because they are not wireless anyways) but the best part is ALL of my other devices are running 5G. 16 devices at once. With the AC1900 1.6Gbps and with Beamforming=, it has a range all around my house and front and back yards of full strength.

This modem is TWC approved and if you see sites saying Xfinity only, do not believe it because they have not updated their sites. Its the best $219 i have ever spent. With its Genie software for both PC and mobile devices, all modem settings can be done in seconds without the need to sign in through a browser. Just thought i would add this comment so that this cablemodem/router can be added to the list. Packaging is updated to state it works with TWC.

I have had mine for about 18 months. Now going through firmware update for two weeks and counting. My download speed on TWC went from 100 to 2, and I get dropped frequently. I have to reboot several times a day. I will never buy another Netgear product, and never a product I cannot update the firmware myself on.

That router and any other WIFI router will work with Time Warner. However, you'll still need to either rent a cable modem or buy one of those listed above and the plug your WIFI router into the cable modem.

I wonder if you could set up a MoCA network to get some of the same features as your Echo network. You can buy devices like these at Amazon: Ethernet to Coax MoCA Adapter Kit
I've never set one up, but maybe you can search for more info on it. I'm guessing you can just buy any of the modems listed above as well as the adapters. Anybody else ever set up a coax network or have a better idea if this would work or not?
