My ISP requires this or a similar modem for gigabit download speed and charges rent. This is under $100 unlike other DOCSIS 3.1 modems. If you’re buying your own modem for the first time you might as well pick something that will be above average for a few years.
Healthy Chris –
I had purchased a Netgear modem for gigabit downloads, only to discover it wasn’t DOCSIS 3.1 and topped out at 500mbps. This is the most affordable modem I could find that successfully hits 1,000mbps.
Jack Molyneaux –
Connected to a new RCN “1 Gig” account. Connection required RCN tech support to record the Touchstone MAC ID; but once that was specified as an allowed modem, it was fast and easy.
Albert Lee –
The Arris CM8200A is identical to the much more expensive retail Arris SB8200, which is certified by Comcast, Cox, TWC, and other cable providers for gigabit service. It can be used in place of its retail sibling with Comcast Xfinity and other services to avoid paying a monthly fee to rent a gateway from them.
I was able to set up new Comcast service (Xfinity Gigabit) using this modem in four easy steps:
* Connect a coaxial cable to your wall jack and the modem’s coax jack, and plug an Ethernet cable into port 1 of the modem and the other end into your router (or directly into a computer for temporary use). Plug the power cable into the modem and wait a few minutes for all 4 of the lights to turn on
* Go to to the Xfinity activation page (which may load automatically), and call the number provided during the equipment activation process
* Tell the representative that your modem’s model number is Arris SB8200 (not CM8200A), and read the MAC address printed on the label when asked for a MAC or serial number
* They will push new settings to the modem, and it will reboot. After a few minutes, it should automatically reboot a second time to install a firmware update.
After this, your internet service should start working. In your account details, the modem should be listed as an “AR SB8200”. If you have problems connecting, go to 192.168.100.1 to check the modem’s diagnostics. The modem’s MAC address is also available on the diagnostics page.

This modem works perfectly with RCN. After plugging it in, I gave RCN a quick call to tell them the MAC address, and they activated it without issue. They didn’t even ask about the model number (and they don’t seem to care that it’s not a normal retail modem).
This modem is also a bit more future-proof than many other DOCSIS 3.1 modems due to the inclusion of a second Ethernet port. Although it’s unnecessary with most (if not all) currently available speed tiers, it will allow this model to support a maximum of 2gbps as opposed to 1gbps.
The only downside is that the modem I received was a bit scuffed, but that’s to be expected with a used device.

Comcast has a lot of confusion about this modem. Took several phone calls to their tech folks to get someone who could make it work and provision correctly. It is a must to tell them that it is a SB8200 – even though the model stated is CM8200A. Eventually comcast sorts it out and gets it working correctly. Have a lot of patience and keep calling them until you get someone who knows something.
StyleAndEntertainment –
This cable modem is 5 stars: it works as expected: connected to Comcast in the SF Bay area and I am getting DOCSIS 3.1 enabled 32 channels down and 4 channels up with ping times of 10ms, download speeds of 160 Mbps, and upload speeds of 6 Mbps. YMMV of course. Check them out for yourself on the modem’s built in web app at 192.168.100.1 and once activated use wwwspeedtestnet to determine throughput.A couple of things to note is this is the North America version and once connected, look for the front panel green lights to turn blue which indicates DOCSIS 3.1 connectivity.
Ye olde Motorola Surfboard DOCSIS 2.0 had 4×4 channel support. On the Comcast 150 Mbps plan, the CM8200A doesn’t make any noticeable difference. Perhaps 4K movies from Netfix and Prime are buffering faster, but it wasn’t really a problem before. So keep that in mind if you are upgrading. I upgraded because Comcast said my old modem was no longer supported, I cut the cord recently so I’m watching more videos, and I like to find great deals to run the latest equipment. As another point of reference, I had the 60 Mbps plan with the DOCSIS 2.0 4×4 cable modem for about 3 months and never had a problem watching 4K HDR or Dolby Vision movies. Typically, 4K requires about 25 Mbps download speeds.
As many have mentioned, this cable modem will work on Comcast even though it is not listed as a supported device. Tell your Comcast technician it is an Arris Surfboard SB8200 and give them the MAC address listed on the bottom. For me, it didn’t work until I rebooted it after waiting the recommended 30 minutes.
Next, I am taking off a star because of the seller Chommy85. Not that they are horrible: I did receive the product sooner than expected, it was a great deal at $84 delivered, it is lightly scratch as expected for a used product, and it does work as described above. However, the product was shipped as loose parts in an unpadded bag from USPS. This included the modem, the power supply and an Ethernet cable. These are not delicate parts, but I do expect them to be wrapped securely in box. Now the next Chommy85 issue is more debatable: the price went up $50 dollars since I purchased it 4 days ago. This may be because the modems left in inventory are not scratched, less used, or the market demand is higher. Don’t know, but it does make this not as great a deal at about $50 less than a new SB8200. I know I would have purchased the DOCSIS 3.0 SB 6190 new, rather than this modem used, at the new price and saved over $30.
Finally, you can find reviews of this modem (OK, the SB8200) and other recent modems here: mbreviewscom/category/modems Frankly, unless you are running a business this DOCSIS 3.1 modem is likely over spec’d for what you can actually use in a home network. But if you find a great deal on it, be assured the CM8200A won’t be the problem behind any bandwidth issues on your network for years to come.

The Arris CM8200A is functionally and technically identical to the more expensive Arris SB8200. It just comes without consumer packaging and is black instead of white. I was up and running with mine in a few minutes including a call into Cox to register it. Make sure to say it’s an SB8200 if you want to avoid issues with it not being on your providers supported modem list. I haven’t upgraded to Gigabit yet so cannot rate the speed. It is providing the exact same performance as the SB6120 I’ve just replaced but that is to be expected.
Tech-Kitten –
This modem is probably an overflow of business modems, which is why you don’t normally see it sold in end-user stores. It was meant for businesses. I’m on Cox Communications 300 down / 30 up and sometimes I get close to 400 down and 30 up.
It doesn’t even have colorful labels on the back, it’s strictly a business modem, but I didn’t care, it has the same functionality as the consumer version Arris SB8200 which is close to $200 at half the price. Save your money and buy this if you’re on a budget.

I bought this to have the latest specs and channels. When I called in to enable it on my account. I told the tech that it was a SB8200. When the tech tried to send it the authorization it errored out. After a little bit I explained to him that it was actually a cm8200. He told me I should have told him that at first. But when he tried to authorize it like that, it wouldn’t take. So he went back to the SB8200. He had a little trouble with it still. Finally what was messing it up was he was sending it an authorization reset that had all the info and the info of course didn’t actually match the modem. So he just sent it a basic reset and let the modem send the info itself when it restarted. That worked. This tech was doing it the way it is supposed to be done but I think some of the techs probably don’t take the time to send the info to the modem and just send a reset. So on this one lazy and using a shortcut works.

I spent hours trying to get Comcast to provision this modem for Gig speeds. This isn’t listed in their known modem for a provision file. They will send the file for the CM820A not the CM8200A. They messed up my modem twice trying to trick the system to take a different file. I do have the blast speeds and get about 300 down and pay for 25o down. But you wont be able to get the full speeds this docsis 3.1 modem should handle until Comcast gets their modem list updated.
kainino0x –
Can be activated on Xfinity if you tell them it is *SB8200*. Working great and provides gigabit speeds! Do not try to activate it as “CM8200” or “CM8200A”; Xfinity does not support it under that name (they only have the slower CM820A). BTW, the product I received was more specifically CM8200A, not just CM8200.
s-mamsu-dvenoh –
I received the modem on time and installation was easy. Comcast walked me through the activation process and when we ran SpeedTest, I got over 200 Mbs download speed. Very happy with this product.
wesmic5 –
It’s not technically supported by Xfinity but as others have stated, claiming the model number as the SB8200 will allow them to provision it with the proper boot file. I have even noticed an an extra 5mbps upload on top of the typical 40mbps I was getting with the ISP rental. If the CM8200 isn’t officially supported by your ISP you’re probably better off getting the SB8200 since it’s not to much more brand new. I really wanted black though and I did save a few bucks. There is a “Do Not Use” sticker taped over one of the ethernet ports though this does not matter for me as I am not using LAG. If you want a more future-proof modem I’d go for the Motorola MB8600 or wait and see if Asus ever comes out with a 3.1 modem. The CM8200 is perfect for my 1GB plan and satisfies my refusal to own white electronics.
KStro9 –
This has been a great modem so far. I didn’t try to run gigabit internet on it yet, although it is on Cox’s approved list for Gigablast. I have been running 300M internet and getting that speed or better consistently. It is a used modem, so it may not be cosmetically perfect, but I had no functionality issues and it is significantly less expensive that the SB8200, although they are functionally the same.. An issue I had, not the fault of the modem, was my router WAN to LAN speed was not capable of the speeds I was getting from the modem. It slowed down to around 170M through the router. I had to replace the router with one that had a faster WAN to LAN speed to be able to use the speeds the modem was capable of.
M. Smith –
Modem working great on Comcast. I told them it is an SB8200 and they had no problems activating it using the MAC address on the bottom. I’m using Comcast “Blast!” 300Mbps Internet service and an ASUS RT-AC66U router running custom DD-WRT firmware. I’m getting over 300Mbps downloads and a little over 10Mbps uploads on hard wired equipment, which is exactly in line with what I’m paying for. Comcast has additional speed packages in my area (up to 1Gbps) but they are more expensive and I don’t need those speeds at this time, however I am confident that this modem could support them if I chose to upgrade.
I only went with the CM8200 instead of the SB8200 because I wanted a black device. All my other equipment is black so I wanted something that matches, LOL. The modem does come in non-retail packaging but this just went into the trash, anyway.
Note that the 2nd Ethernet port on the modem does not work. From my research this port only works when the device is in LAG (Link Aggregation) mode – if you have a router with two WAN ports, for example. Some people have mentioned being able to get it activated by their ISP’s, but this seems very rare.
