The Arris SB6183 remains the best approved modem for Comcast Xfinity, but there is a better future proofed compatible option we have listed below as well as the best voice modem. Best wireless router to use with Comcast? We have 3 options for you depending on how big your house is. It’s no secret that you can save money every month and improve your download speeds by obtaining the best replacement modem for Comcast. To save $10 a month, instead of renting from Comcast, you just buy your own compatible modem and save $120 a year. But with so many options and weird technical terms like DOCSIS 3.0 and channel bonding, which modem should you obtain for your home? I’m here to help you overcome that task. Here are the best devices for each situation. All modems are fully compatible with Comcast and approved for and Time Warner and Cox.
Approved Comcast Compatible Modems

| *Notes: Max speed is for the SB6141 is 343Mbps, it is an old nearly End of Lifed modem and they will not provision it for more than 100Mbps, even then you will have issues with only 8 channels. The SB6183 is the best modem for all but 1GB speeds and if you have Gigabyte speeds you must get the future proofed SB6190. |
Sources: All are compatible with all Xfinity Internet Packages. That includes all Performance, Blast, and Extreme packages.
Best Comcast Xfinity Voice Modems
Please note that if you have Comcast Xfinity voice Triple Play, you can NOT use any of these replacement modems. You are forced to get the telephony EMTA voice modem that has been approved for Comcast. It is your only option, even if you do not use the actual telephone part of the service. All non voice modems will not be compatible.
Save $10 a month, $120 a year. Buying one of these approved modems will pay for itself in less than a year and save $10 every month forever.
Get faster speeds! Often times you’ll get better constant speeds with your own new higher bonded channel modem. No more intermittent slow periods.
Why not to get the cheapest modem, the SB6141?
Full Modem Comparison Chart. It’s simple, it’s out dated. The older cheaper modem won’t be around very long because the newer technologies require more bonded channels like the following two modems. The SB6183 is the perfect modem choice for you. It can handle all of the current Comcast cable speeds(as well as all other cable internet providers) and is the best modem for current Comcast packages. The SB6190 is ready for the next wave of speeds and has more bonded channels for better constant performance.

Wireless Mesh Networking is the newest technology in wireless and the only way to go for a really large house or mansion. Especially if you are trying to get wireless to a guest house out in the backyard.
Isn’t a combo modem router the best option?
I highly recommend the two separate devices over the combo modem router.
Reason one: It’s the best. The SB6183 and any of the wifi routers above is a better option than the single combo modem gateway. That is why the higher cost. If you want the better option, you pay more.
Reason two: If something were to ever break(it shouldn’t), then you only have to replace or upgrade one device instead of the whole combo unit.
Reason three: You get a lot more control with the built in ASUS GUI(Graphical User Interface) and it’s really easy for even someone non technical to use and you can learn basic home networking from it.
Reason four: The main reason, better speeds at range.
Do not buy a used modem!
Unfortunately in almost all cases you MUST buy a new modem. Do not buy a used modem because often times they are on a closed account in another state and you do not have permission to add them to your own. It’s silly but I know how much trouble those agents have when the modem has previously been provisioned on an existing account. They will even make you go into an actual retail location to prove you have the device in hand and are not hacking another customers account by trying to use their modem.
End Of Life Modems
There is a lot of worry and talk about EOL’d Comcast modems. However if you look at their own approved modem list and sort by latest DOCSIS 3.0 retail modems, they’ve only EOL’d one cable modem at all(photo). Do not worry about a Motorola ARRIS being on the End of Life list because as you can see, they are not. Even if they were added way down the line, once you’ve activated the modem, it is on your account and will continue working until you trash it. Some people have reported that they put the SB6141 on the end of life list, however I do not see it on the list so buy that one at your own risk.
Benefits to buying your own modem
- Save $10 every month
- Disable Comcast’s Public Hotspot coming out of your router
- More control over home network
- Faster speeds
- Newer Equipment
Save money on your cable internet bill.
Currently it cost $10 a month to rent a modem from Comcast. This means that in just one year you pay them an extra $120 in fees that you can be avoiding. I’ve had them for at least 12 years now, meaning that’s a savings over over $1,200! And I will likely have them forever. Trust me, stop renting, buy your own supported modem.
Improve your Comcast speeds.
Oh, you need another reason to save money? With the ARRIS / Motorola Modem your internet service will usually improve. You’ll no longer experience random disconnects from old recycled overheating cable modems that have not only been rented to you, but likely many other people prior to you. There have even been stories of rental equipment coming with cockroaches in them! Get your own new replacement modem.
The right technology ensured.
These are for the current DOCSIS 3.0 networks used by all internet providers.
How do I install my modem?
This modem is plug and play. Meaning all you do is screw in the coax cable that comes out of your wall and it works. You don’t have to set it up or know how to access the built in firmware to configure anything. You just hook it up, wait a moment and POW. Super fast internet speeds. OK, I lied, there is one step you must take care of. Because you are using your own modem you must call Comcast / Time Warner or whomever your cable internet provider is and give them the MAC Address of your new modem. This sounds difficult but it is not. The MAC Address is very clearly labeled on a sticker on the bottom of the equipment. Customer service must register the MAC to your account that one time only. After this you never have to talk to them again.
Important Note: Do NOT buy a used modem. It is likely already registered to another persons account. While I myself as an ex agent know it is possible to remove the modem from the old account and put it on the new one, many agents do not and it will be such a hassle. You do not want to end up in this situation because it could leave you without internet for a while and in limbo. It has been reported that some agents even say you must physically go into a local store to have it activated. Why? So they can see that you actually have the device in your hand and it is not in a home where the old account says it is. This is blasphemy and can be avoided by buying new.
Compatible with Comcast/Xfinity, Cox, Charter, Time Warner, Mediacom, Bright House
This modem not only works for Comcast, it works for any major cable ISP running on the DOCSIS 3.0 Network such as Time Warner, Charter, Cox, Mediacom and more. It has many bonded channels and even with all four of us in the house streaming Netflix or playing video games online at the same time, it still has bandwidth leftover.
Check Out These Fastest Modem Speeds.
This is my report. Yours may vary based on what package you pay for, who your ISP is and where you’re located. But with this modem I can bust 120MB on the daily. Older modems and even modems Comcast has provided me with lingered between 10-30MB. Break out, get your full potential speeds and watch Netlfix streaming in High Definition like you paid for.
Notice how it says faster than 90% of the US?
Because most people don’t have their own modems!
But there are other factors like location and ISP.
You can run your own speed test here.
Join the boycott!
As a person who lives in The Matrix, I need the best internet provider, meaning I am forced to subscribe to Comcast. But I am not forced to rent a modem from them and my form of boycotting is buying my own cable modem and not letting them get that extra $10 on a monthly basis. Do yourself a favor, join me and save $120 a year!
