Charter Spectrum Compatible DOCSIS 3.0 and DOCSIS 3.1 Cable Modems

Modem list updated November 2018. 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 Spectrum 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.

If you're paying $7 a month to rent a modem from Charter Spectrum, that's $84 a year or $420 over 5 years. You can buy a new one for less than that. There are used ones that will pay for themselves in less than 3 months.

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


DOCSIS 3.0 and DOCSIS 3.1 Cable Modems

Cable Modem Buying Tips and FAQ's

All Charter Spectrum Internet Service subscribers, buy any of these DOCSIS 3.0 or DOCSIS 3.1 modems. If you subscribe to plan up to 100 Mbps, choose a modem with 8 downstream channels to maximize your speed. For plans up to 300 Mbps, buy one with at least 16 downstream channels. For higher speed plans, but a modem with 32 downstream channels. If you have telephone service with Charter Spectrum too, these won't work.

This list also includes minimally qualifed modems. You can read more about that here: Minimally Qualified Modems

All of these modems are high quality and have pretty much the same features, except for number of downstream channels and those with routers built in. So don't worry too much about deciding which one to buy. Price should be a main factor in your buying decision. Buy one now and start saving those rental fees!

Minimally Qualified Modems

This is Spectrum's statement about minimally qualified modems that can be found here: Charter Spectrum Approved Modems List

"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."

"Note: If you attempt to install your own device from our authorized modems list that doesn't meet the speed tier you ordered or if we can't determine the device qualification, you'll get a message that notifies you of this, and you'll be asked to acknowledge this before you proceed."

Michael (Billings) says...
I know nothing about modems.
I have Spectrum phone and internet service and an Arris TM502G. If it makes sense I would like to replace it with something that will be approved for Spectrum Phone and Internet.
I see their list but I can't tell if they are for BOTH phone and internet. All I see is internet.
Can anyone help this novice?
Thanks in advance. Michael
Ed (San Antonio) says...
Going to sign up with Spectrum internet so would it be better to buy a modem without the Wi-Fi connect and then buy a separate one and if I do what do you recommend 100 mp is what I'm looking at
Wounded Warr1or (Clarksville) says...
I have been using the Motorola SBG 6580 for a few years which is a combo modem / Wi-Fi router without issue. Although, I used to be satisfied with both the wireless and wired connections, it now seems as the Wi-Fi is hit and miss. It seems the tech has changed to AC from N, which was the latest when I purchased the SBG 6580; which is the best proven bang for the buck currently; a lot of these posts are pretty dated. Please advise .. Thank you. Peace

Very Respectfully,
WX2

Jeffrey (Santa Clarita - Ca) says...
Does anyone know if their are any DOCSIS 3.1 Modems that are approved/ work with Spectrum?

Replies would be appreciated. Thank you.

JoeTee says...
I have Spectrum 200Mbps d/l and 10Mbps u/l speeds respectively. Spectrum charges $5 a month to activate the wireless capability of the Ubee36C modem. I am currently using a D-Link DIR-815 router but can only support up to 60Mbps on wireless, direct cable to the router I get 220Mbps d/l and 12Mbps u/l. Can anyone recommend a modem/router combo that will work with Spectrum (TWC) service? Thank you.
Barrett Powell (Cary) says...
I went to Best Buy last year and was told my Netgear C6300 was compatible with Time Warner Cable. I have the 300mb modem service. Charter took over and 3 weeks ago my service went out for 2 days while they upgraded equipment. Now my service only gets 10mb to 78mb and is spotty at best. I use 5G Wi-Fi in my house for some devices and don't want to give that up. Advice? Do I need a new modem...again?
ITAdmin (Mad Town) says...
Do not buy any Arris modems as they are severely bugged right now. Intel chipsets are causing modems to perform very poorly and you will be causing yourself a lot of headaches and throwing money down the toilet. I repeat, do not buy any modem that has Intel's Puma chipset. Puma5, Puma6 and Puma7 chips are all affected. You will experience disconnects, bad speeds and huge amounts of network latency (which kills streaming and gaming online). BUY AT YOUR OWN LOSS.
Wicked1 (Norco Ca) says...
Hey Dan, i was thinking of buying the SB6190: since u are saying there is an issue w/ the Arris Modems, which Modems should we be looking into?
Eddie (Edinburg) says...

MrMike (Detroit) says...
I have a Arris TM822 Modem, and a NETGEAR Nighthawk X6 R7900 Router. The speed is fine for most of the time. But, when I'm streaming live TV on Apple TV, it looks slow and grainy. I'm wondering if I should update my modem? I think, I've had it for over 5yrs? Any Suggestions?
Dan says...
I'd first try plugging your computer directly into the TM822 modem and doing an online speed test. If you get over 5 Mbps download speed, that should be enough for HD video. If you have other devices sharing the internet and watching video, you'll have to multiply that 5 Mbps by the number of devices to see what download speed you'd need.

If that checks out, try putting your computer next to the Apple TV and try doing a speed test over Wifi and see if you have enough speed. If not, its a wifi problem and not the modem.

I had a Roku box using wifi that had terrible video quality. Moved the box 6 inches from behind the TV and Presto! perfect video.

Anyone else with suggestions?

Cliff (Dfw) says...
I just bought a Arris SBG6580 combination modem and router, got connections, but security screen appears and once contacted charter they state it does not support the phone only the internet ???

It has the modem inside and recommended on Charters website, I tend to wonder are they telling the truth just do not want you to buy your own, so they loose out on rental as I am paying $10 per month !

CR Smith says...
I have Spectrum/Charter HD cable service. I need [wireless] WiFi capability.

I'd like to purchase a WiFi router/modem [one unit] that is compatible with HD Spectrum/Charter.

Grant says...
You don't want a 2 in 1, believe me. It's almost always better to buy separate units as the wifi range and speed usually suck
Md. Imranul Islam (Worcester) says...
I'm paying $5/month for wifi router. Could anyone please suggest me which router I can buy from Amazon/Walmart/Bestbuy that is compatible with charter spectrum?
Ernie (Grants Pass) says...
I have this one and works great. NETGEAR - Nighthawk Wireless-AC2300
Best Buy has it for $149.99 right now
Charlene says...
Ernie -- is this NETGEAR - Nighthawk Wireless-AC2300 both modem/wifi -- two in one?
Joe (Long Beach) says...
Does anyone know how many downstream channels Charter offers? I actually get their upgraded Spectrum Internet Service and was wondering about this. I'm not sure where to find this information. I am debating buying the SB6190, but if I can't take advantage of it's expanded channel capability, then I'll save a few bucks and get the SB6183.
Shawn (Staten Island) says...
Joe, it say's on this page that you need 8 channels for more than 64mbps, and 16 for more than 100mbps. It also say's that the phone will not work with modems with 16 channels for some reason. I really don't see why not unless they are just trying to price gouge people, but it's something they should address. I'm not sure if it also apply's to the 8 channel modems as they didn't exactly specify that.
Karl says...
Actually, Charter no longer charges a separate fee for the modem; it's included in their package pricing. So buying your own modem won't reduce your bill.
Chad says...
Not true. I came here looking for a good one for my brother who just signed up with Spectrum. He's getting charged $5 / month for a modem with built in wi-fi capability.
Frank (Mascoutah) says...
Spectrum modem is included; Spectrum modem with built-in Wi-Fi is a $5 per month charge. Two different pieces of equipment.
Black (New York) says...
Spectrum does not charge for the modem, but charges an extra $5 for wifi service, not the wifi modem/router
Boomer (New York) says...
Fact. This is the correct answer.
Jason says...
Will the newer model SBG6782-AC work as well? It i really hard to find info on newer modem/router combo's that work with Charter.
Dan says...
As of right now, the SBG6782AC is not on Charter's list of authorized modems. However the SBG6700AC and the SBG6900AC are on their "Minimally Qualified" list, meaning they'll work on Charter but haven't been thoroughly tested for speeds at various tiers. Guessing they'll work fine. Here's links to both at Amazon: SBG6700AC and SBG6900AC
Jason says...
Thank you so much for the reply. I am moving next week and set up installation with Charter. I will go with the SBG6700AC.
alexander says...
i been thanking of buying me a router from walmart that really advanced but i kno it not on list. what would happen if i wa to buy and use one
Steve (Sauk Rapids) says...
If I understand this correctly. If you buy one that is not supported by Charter, it won't work. You need to buy one that is supported by Charter.
Megan Pritchard (Saint Louis) says...
I've been through several now that haven't worked with Charter, but Charter set up doesn't explicitly state it. In fact, Charter reps have even said "it seems the modem/router is broken and you need a new one". This was the case with Motorola MG7550. I'm still searching for one that is good and works.
David Menke (O'fallon) says...
Do any of these modems have a phone jack on the back?
Dan says...
No. The only DOCSIS 3.0 modem on the the Charter list that has a phone jack and is readily available to buy is the the Arris TM822G. Here's a link to it on Amazon: Arris TM822G
