Several devices appear on the Suddenlink approved modems list. You will find the best approved modems based on WiFi and value below. Suddenlink no longer maintains a official approved modems list. Suddenlink states as long as you use a DOCSIS 3.0 modem (no voice modems), it should work with their network.
Suddenlink does not support DOCSIS 3.1 modems, nor do they support voice modems. If you require telephone service, you must use a Suddenlink eMTA (cable modem and telephone adapter). You can still use your own cable modem for internet service.

Suddenlink Company Information
Suddenlink Phone Support: 1-877-694-9474
Suddenlink serves the following states: Arizona, Arkansas, California, Kansas, Kentucky, Louisiana, Mississippi, Missouri, Nevada, New Mexico, North Carolina, Oklahoma, Texas, and West Virginia.
I am looking at an ARRIS SURFboard SBG6900-AC to use when in Arizona for the winter with sudden link and use in Montana with century link the other half of year. Will this work?
No, this will not work. Suddenlink requires a cable modem and CenturyLink requires a DSL modem (two different technologies).
The ARRIS SURFboard SBG6900-AC is a cable modem, but not currently compatible with Suddenlink. You will need two different modems for your use (please refer to each company’s approved modems page).
Suddenlink Approved Modems
CenturyLink Approved Modems
Not true I am currently with Suddenlink and am using the 6900AC
Thanks for the reply, Aron. Contacted Suddenlink – waiting for a response on this.
Update: Suddenlink says the ARRIS SURFboard SBG6900-AC “should” work with their network, but the modem does not appear on their official compatibility list.

I’m in the process of buying my own equipment I have suddenlink internet, Netgear CM500 is all I need or I need something else? Thank you.
You are correct, you will only need the NETGEAR CM500 modem to connect to the internet.
Anyone know if the Arris SB8200 is approved by Suddenlink yet ? This is a DOCSIS 3
.1 Modem but fully backwards compatible. Thanks. What is up with the Intel Puma Chip set ? Gee whiz folks.
The ARRIS SB8200 may work in your local area. You can contact Suddenlink on their site to find out – give them your address.
Yes, the Intel Puma chipset is an absolute mess for the modem industry – made worse by continuing to sell these defective products on the market years after the defective discoveries.
I have seen some people say they are running the Netgear MB8600 on Suddenlink are any of you?
You maybe able to use the Motorola MB8600 (the MB8600 is not a NETGEAR model) with Suddenlink. If you want to be absolutely certain the device will work in your region, you should contact Suddenlink for verification. Officially, Suddenlink does not support DOCSIS 3.1 modems; the MB8600 is a DOCSIS 3.1 modem.
I bought an MB8600 back in Mid 2017 with the hopes of working on my Suddenlink service – at the time, it did not. I spent a fair amount of time on the phone with a seemingly capable tech trying to get it online to no avail. That was then. Maybe now, 3-1/2 years later, Suddenlink provisioning works. I may research it, because I ended up with using a ARRIS SB6190 which is now on the sh*t list even though is seems to work.
Thanks for the info, Timber. The official word from Suddenlink is they do not support DOCSIS 3.1 modems., but select people may get them to work in their region.
I too am shopping for my own modem/wifi combo and I will also need voice for Suddenlink service. Will the Motorola MT7711 work?
Frances L., the Motorola MT7711 may work with Suddenlink. Contacting Suddenlink directly with your location will hopefully give you the answer you are looking for your desired device. Good luck, Frances!
Will a AT&T Motorola NVG510 router ; modem combo work?
No, Efrain, the Motorola NVG510 modem is for DSL connections only. Suddenlink requires a cable modem.
I just wanted to chime in here and say that I am now using an Arris (CommScope now?) SURFBOARD SB8200 DOCSIS 3.1 cable modem with Suddenlink now. There are a couple of caveats though. One, is that while it does connect and work, it does not yet go into DOCSIS 3.1 mode. It is still only operating in DOCSIS 3.0 mode. You can tell this because the uplink and downlink indicators stay green and do not change to blue. According to what I have been told, they are still working on getting the DOCSIS 3.1 support enabled on their backend network. Two, is that they are still not pushing a modern firmware for the modem. Since the cable provider is in full control of what firmware is used, it is pretty irresponsible of them not to push the latest firmware to address any security concerns that may have been addressed in newer firmware releases.
It is sad that companies like Suddenlink just do not seem to be capable of managing their networks correctly.
Thanks, Richard, for your informative comments. Suddenlink does not support DOCSIS 3.1 modems (nor voice modems). Their network is really limiting compared to other ISPs, unfortunately.
Question – I am wanting to upgrade to a 400GBS Internet service on Suddenlink. I have our phone line through there as well – the phone is strictly Analog and uses the old phone lines. Is there a new modem that will allow me to continue with the phone service as well as upgrade to the 400GBS service?
No, Richard, Suddenlink does not support voice modems. You must use a Suddenlink eMTA for phone service. You can still use your own modem for internet service.
Can you explain this a bit? “You must use a Suddenlink eMTA for phone service. You can still use your own modem for internet service.”
I have a phone landline through Suddenlink’s service like the post above. Is the Arris TM822 that I got from them the “Suddenlink eMTA” you’re referring to, through which I can continue to get phone service? How would I connect another upgraded modem of my own for internet service with the TM822 connected to the cable?
Still waiting for Suddenlink to give an official response to this situation. If you got the eMTA from Suddenlink, you should be able to continue to use that for phone service. Suddenlink has stated that there is no charge for a phone modem.
To connect multiple modems together, you may be able to use a cable splitter or multiple coaxial cable connections if your home has them. Will post confirmation when Suddenlink responds.
Confirmed with Suddenlink that you may use a cable splitter to connect multiple devices. So if you have a phone modem, internet modem, and a TV connection, you would need at least a 3-way cable splitter.
Can I use a netgear cm500v with my suddenlink service. I am having issues with the original router provided. The router just shuts down and takes awhile before it restarts. I just want to purchase a router to support my voice and internet.
No, Bobby, Suddenlink requires use of their own telephone adapter (eMTA) for phone service. You would be better off purchasing a modem without voice like the NETGEAR CM500 and a separate router to use along with the Suddenlink provided eMTA.
Ok, so I’m considering switching to suddenlink because I’m unhappy with ATT. Suddenlink is my only other option in my neighborhood. According to their website, If i want their 1GB speed I need a 32×8 channel modem. However, on your website all the 32×8 modems have the puma chipset that you recommend not buying. Would a 24×8 modem work with 1GB service? Or would it be better to not get the 1GB service and instead get the 400mb service and downgrade to a 24×8? Or, are there some 32×8 modems I can buy that are compatible with suddenlink that dont have the puma chipset?
thanks for your help and info.
The problem with Suddenlink is they don’t support DOCSIS 3.1 modems. If they did, Michael, you would have a lot more choices for a modem. So, you are either stuck with one of the Intel Puma chipsets modems or get a modem from Suddenlink so they can deal with any issues you may have with a bad modem (lease fees may apply). The other option is to just go with a slower speed and get a non-Puma device for now and wait for DOCSIS 3.1 availability (there are a few DOCSIS 3.1 modems that do not contain the bad Intel Puma chipsets).
You could wait for Suddenlink to start offering support for DOCSIS 3.1 modems, but that technology is not new and has been around for a few years. The fact that Suddenlink still doesn’t support DOCSIS 3.1 is alarming.
You can use a 24×8 modem for 1 Gbps service but you will not reach the full speed of the service you are paying for (you are kind of wasting money paying for something you are not taking full advantage of from your speed tier).
Hope that helps, Michael.
Thanks alot for the info. We’ve been making it work with 50mbps for 4 years so i think 400 should be plenty. I’ll prob go that route. This site was a big help, thanks.
Michael, 400 Mbps speed would certainly feel a lot faster than 50 Mbps. Glad you found this site useful.
Don’t do it. You will regret switching from AT&T. Trust me on this.
Anything faster than a T1 connection is fast for me, LOL. I’m on a legacy plan with blazing 3 Mbps download speeds. The Ambit modem I’ve rented for 12 years now seems to be dying. The last electrical thunderstorm that rolled through may have got to it. Thinking of buying a MB7621 to replace the rented Ambit. Upgrade data plan some day soon.
Do I have to schedule a tech to come out and baby sit the installation of the new modem? Or, can I just plug-n-play it and then call someone at Suddenlink to enable it on their network?
Forrest,
You can install the modem yourself and save the hassle of someone coming into your home. Suddenlink provides this high-speed Internet connection guide to walk you through the process.
Stay safe, Forrest!
Im looking for a router modem combo with a phone jack that will work with Suddenlink 1g service and Im having a hard time finding one. I contacted Suddenlink directly and they said I should ask someone at Best Buy. I did that and they sent me back to suddenlink, then I tried Arris and Netgear directly and they didnt know. Im okay with a seprate Modem and Router, can you tell me what you would rent me?
A phone jack will do you no good with Suddenlink service. If you need phone service, Suddenlink requires use of their own eMTA (cable modem and telephone adapter). You will need to contact Suddenlink to rent a phone modem from them.
Rusty, stay safe!
Comment on the Arris SB6183 and Suddenlink compatibility: Suddenlink pushes an old firmware version (SB6183-9.2.0.0-GA-03-29-NOS) onto these modems.
This firmware has known bugs that can cause connection and download issues. The firmware has been fixed by Arris, but the bad firmware continues to be pushed out by Suddenlink.

Many other ISPs (Time Warner Cable, Comcast, etc.) starting pushing the firmware update around 2015/2016.
Thanks, John, for sharing this info with everybody.
Question, why does the Netgear C7000vs say “For Cable Plans Up to 400 Mbps ” in the title but looks liek it can go faster by the specs?
Hello David,
Most modem manufactures state faster speeds on their packaging than the ISP (Internet service provider) actually allows. There are various factors that slow the capable speeds of modems (network capabilities are a determining factor). Many ISPs present Internet plans at 100 Mbps, 200 Mbps, 400 Mbps, then it jumps up to 1 Gig service levels, which the C7000 is not capable of hitting (you need a DOCSIS 3.1 modem to reach 1 Gig speed). So for some ISPs, the C7000 will only be good for up to a 400 Mbps plan. If an ISP offers a 500 Mbps or 700 Mbps speed tier, the C7000 should hit those speeds if the ISP allows it.
Keep in mind, the speeds on the modem package are not a guarantee.
You can read more about inaccurate advertised speed claims on the Cable Modem Buying Guide.
Stay safe, David.
We have Suddenlink for Tv, internet and phone. We have 2 modems, one for phone and another for internet. The internet modem is Arris TG2482A and then there is an Actiontec ECB2500C (which appears to be a splitter) and the phone modem is Arris TM822G.
My question is can we consolidate to the Arris TG2482A and eliminate the Phone modem?
Sorry, Judy, Suddenlink requires use of their own eMTA (cable modem and telephone adapter) for phone service. The only way to get rid of the ARRIS TM822G is to drop phone service.
If Suddenlink provided both of the ARRIS devices to you, then they can’t utilize the ARRIS TG2482A as a phone modem. If Suddenlink could activate the phone portion of the ARRIS TG2482A that would obviously solve your issue since the TG2482A has everything you need in one device.
