13 best cable modems for comcast cables

Comcast is a popular internet service provider in the United States, and they offer internet services through cable modems. Cable modems are devices that provide internet connectivity by using cable television lines. When it comes to Comcast, they often recommend specific models of cable modems that are compatible with their network to ensure optimal performance. These modems are designed to work seamlessly with Comcast's internet service.

When choosing a cable modem for Comcast, it's essential to consider a few factors:

  1. Compatibility: Make sure the modem you choose is certified by Comcast.They maintain a list of approved devices on their website, so you can check there to ensure compatibility.

  2. DOCSIS Standard: Comcast primarily uses DOCSIS (Data Over Cable Service Interface Specification) technology for its cable internet service. It's essential to choose a cable modem that supports the latest DOCSIS standard (such as DOCSIS 3.1) for faster internet speeds and better performance.

  3. Speed: Consider the internet speed tier you are subscribed to with Comcast. Choose a cable modem that can handle the maximum download and upload speeds offered by your Comcast plan.

  4. Modem Router Combo: If you prefer a simplified setup, you can opt for a modem router combo. These devices combine the functionality of a cable modem and a wireless router in one unit, reducing clutter and simplifying your home network.

  5. Channels: Cable modems have channels for uploading and downloading data. Modems with more channels can handle higher internet speeds and are less likely to experience congestion during peak usage times.

Popular brands that manufacture cable modems compatible with Comcast include Arris, Netgear, Motorola, and TP-Link. It's recommended to read user reviews and check for any additional features that might be important to you, such as built-in Wi-Fi, multiple Ethernet ports, or advanced security features.

When setting up your Comcast internet service, follow the provided instructions to activate your cable modem properly. This usually involves connecting the modem to the cable outlet, powering it on, and activating the service through Comcast's online portal or customer service hotline.

Remember that Comcast's approved modem list may be updated periodically, so it's a good idea to check their website or contact their customer support for the most current information on compatible cable modems.

User questions & answers

Question: So how do control the cable modem if comcast doesn't provide one
Answer: Once you install the modem you can either go online and register the device or call Comcast with the serial number. It will then activate and you are good to go. I’ve had no issues with mine at all. And online registration was very easy.
Question: Quick start quide says it doesn't have wifi capability or router. so, can i get to xfinitywifi wirelessly or not
Answer: Model MB7621 is a bridge modem, or a Cable modem without a built in WiFi router. You can either purchase an all in one (modem with the built in WiFi router) such as a Motorola MG7700, or purchase a a WiFi router to connect to the MB7621.
Question: Which one is better for my needs - the mb-7621 or the mb-7420? comcast highest speed for home use is 150 mbps and 100 for downloads

Good for future upgrades of your internet speed if needed. 3. The 7621 came out in Dec 2017 vs 2015 for the 7420, newer tech, longer support from right now.

User questions & answers

Question: Is this compatible with AT&T
Answer: Model MT7711 or any (DOCSIS Cable modem/router) is NOT compatible with AT&T.
Question: I just updated my account to the 1000mbps plan and I want to get the most of it. Would I be able to get the 1000mbps download with this device
Answer: My internet speed when Comcast provides xfi modem is >300 Mbps down (even wifi) which is what my plan is. However everytime I plug this modem and replace comcast modem - the internet wired connections throttles at a max of ~174 Mbps Wifi sucks at ~74 Mbps Upstairs ~43 Mbps Very disappointed with this product. I have spent numerous hours with comcast tech and they rewired my connections. NO LUCK !!!
Question: Mt7711 reverts to eroute_dualmode from bridge mode either upon reboot or triggered by xfinity. has anyone figured out how to keep it in bridge mode
Answer: Bridging the connection is entirely dependent on your internet service provider. Some providers have a configuration file which will overwrite the bridge mode any time you reboot your modem (When your modem or gateway reaches out to their DHCP server, it locks to your modem's MAC address). You can try calling your internet service provider and ask them to release your DHCP lease, which will make the network have to relearn what MAC is associated with your account. However, it may not be permanent and will just revert to previous settings again. If you have more questions, please call our support team at 1-800-753-0797 (Monday-Friday 8:30am-10pm, Saturday 8:30am-5pm Eastern Time)
Question: I have comcast triple play and plan to reduce service to comcast internet only with Ooma phone. Is this a good choice to accomplish this transition
Answer: I also have Comcast/Xfinity Triple Play. With all of the Premium channels it cost me $159.00 per month when I add the phone and went to Triple Play 3 years ago. Late last year my monthly bill had gone up to $292.00 per month and they were talking about raising the price another $18. I dropped all of the Premium channels, turned in one of the three HD adapters and bought this MT17711 so I didn't have to rent one monthly. My bill dropped down to $191.30. This modem is excellent. It has faster Internet speeds and my devices located outside no longer drop off. I still have the X1 DVR and can live without the Premium Channels. Installation was simple and all done right online without having to call Xfinity.

User questions & answers

Question: I want to buy this latest model mg7700 asap, when is gonna available
Answer: Not sure about the answer to your question. The MG7700 is very popular at the moment and all you can do is keep monitoring availability.
Question: What is the range of this modem? I'm looking for a strong signal throughout a 4,000 sq ft home
Answer: Model MG7700 should provide coverage to a large house. Unfortunately, because of so many variables involved, there isn't a way to measure the range (or speed) experience a user will have. Factors, including positioning of the Gateway, building materials, obstruction or even your neighbors WiFi usage, play a role in what will both range and speed. That said, model MG7700 is equipped with a sophisticated built in Dual Band AC 1900 WiFi router. Support for concurrent 2.4 and 5 GHz bands with AnyBeam beamforming at those bands, focuses the signal on wireless clients to allow further improvements to wireless performance, including range. Model MG7700's built in WiFi router will increase your chances for a better WiFi experience over other Gateways on the market.
Question: Do you have to pay for extended phone tech support in the event it stops working
Answer: Motorola has a pretty decent 2 year warranty, with good phone support even through this Novel Corona-virus causing many companies to lessen customer support. This is a solid modem that saves me $185 every year with Comcast. It's interesting as I had Comcast service 12 years ago and back then one could own their own modem to save you $15, but they would charge you the same $15 for the access card a month. I went back to Comcast as Frontier is at deaths door. These days Comcast doesn't charge for the access card as the FCC put the kibosh on cable companies being in the cable rental business. At the end of the day, this Motorola's paid for itself twice over and still counting.
Question: Are you able to install firmware updates? When I owned a combo modem+router, Cox locked out firmware updates because it was a cable modem
Answer: No, you can't personally update the firmware, apparently, the cable company gets it from Motorola, and updates it for you. I guess for compatibility or maybe some other reason.

User questions & answers

Question: How warm does this modem run? Some of the more recent SB modems ran too hot, leading to early failure
Answer: Handling of heat was definitely considered in the MB7420 design. All cable modems generate heat, the good designs get rid of the heat efficiently. The MB7420 is very well ventilated on both sides and on the top, and has robust heat sinks on the circuit board to dissipate the heat. The vertical design also helps air circulation. The two year warranty is the longest in the industry and speaks to the durability of the product. With that said, definitely do not operate the MB7420 on its side. The MB7420 is intended to be in a vertical position.
Question: Are the leds insanely bright like on other motorola modems
Answer: Whether the LEDs have the right amount of brightness is an opinion. The MB7420 LED brightness was reduced in response to user reviews on earlier modem designs. Definitely attention was paid to the output level and the electronic design throttled back the brightness. You will probably find it a good, but can't say for sure. Your opinion would be welcome.
Question: Can the stabilizing foot be removed so the modem can lay on its side? Is it screwed/clipped on
Answer: The foot is attached with 2 screws under the label. It is designed to stand up on the foot to allow for adequate cooling for the modem at high speeds. It is not designed to lay flat on its side with one panel blocked. It is recommended that both side panels and the top not be blocked. Laying it on its side and blocking the ventilation could produce improper operation and unit failure.
Question: Is this part of the arris motorola surfboard line up of modems
Answer: No, it is not. This is a much newer design. The MB7420 has a Full Band Capture Digital Tuner, upgraded power handling to protect against lightning and power surges, robust heat sinks to handle a broad temperature range. And the MB7420 looks a lot better than the Arris SB6141.

User questions & answers

Question: How is this model different than the arris surfboard sb
Answer: The sb6121 only has speeds of 172 Mbps download and up to 131 Mbps upload. This model has up to 343 Mbps download and 131 Mbps upload.
Question: Going with the cable modem option what’s the best router to pair this with for spectrum
Answer: It depends on your needs. Needs are based on the number of devices connected and the size of area you are trying to cover. I would highly recommend a mesh network unless your home is 1200sqft or smaller. A centrally located router could cover that. The biggest problem is getting the 5ghz frequency to reach throughout the home. The 5ghz gives you speeds over 30mbps on wireless devices. 5ghz will reach roughly 40ft in all directions from your access point (ap). A mesh system gives you multiple ap and thus more area covered by the 5ghz.
Question: How many devices can connect at once? Is that that the 8x refers to
Answer: The 8x doesn't refer to the number of devices you can connect to it. You only want to connect one device and that's your WiFi router. You wireless router determines how many devices can be connect based on the available number of ip addresses on the wireless device. The 8x refers to the speed of Data Over Cable Service Interface Specification (DOCSIS). Its informing you on the speed of DOCSIS 2.0 vs the newer DOCSIS 3.0. Ultimately your speed will be determined by how much you want to pay your internet provider. And you can determine how many devices you want to connect by the router you choose.
Question: Do I also have to buy a router for the modem? And to make sure it obviously speeds up internet connection right
Answer: If you only need to have one computer hooked up to the internet you do not need a router. If you want to hook up more than one computer or if you want a wireless network, you will need to buy the appropriate router. My internet speed went from 20mb to 100mb(the speed I pay extra for). TWC has also stopped charging me $8.00 a month for the use of their inadequate equipment.

Question: Does this modem have netgear genie
Answer: Hello Thank you for contacting us. It has Netgear Genie App Management. Any questions please contact us again. Thanks.
Question: I see many ppl asking about a router and answers say “modem only” but the description says wifi modem combo. what am i missing
Answer: The confusion is due to the illogical way Amazon links questions and answers to products. There are several different products listed on this one product page. Some are just modems, others are modem/router combos. Unfortunately, all the different products on this page share the same questions and answers which aren't relevant to one another. If the description on the product you have selected says it's a modem/router combo, then it's a modem/router combo. The people saying it's only a router are answering the question based on the product their viewing or have purchased. This is a problem that effects many products throughout the Amazon site.

User questions & answers

Question: Confirming that only one device can be connected to the modem, despite additional lan ports? you can't connect, say your pc and a router at same time
Answer: The MB8600 will allow for one device. You can connect your PC to the MB8600, or connect a router to the MB8600.If, in the very unusual situation, you are paying for and receiving more than one IP address from your provider, then you can directly connect up to 4 devices to the MB8600.
Question: I also need wifi, what do you recommend
Answer: The MB8600 modem will work with any WiFi router. Given the speed of the MB8600, you should be using at least an AC1900 router and given the other devices in your network, you might be able to take advantage of a wireless speed even faster than AC1900.The Ethernet port on the MB8600 simply plugs into the WiFi router of your choice. The router should be current enough to have a Gigabit WAN port (10/100/1000 Ethernet port), since you will need that for the speeds that the MB8600 can deliver. And for now, 1 Gbps service is the fastest cable service Comcast is providing in the US. When Comcast or other cable Internet service providers begin providing service speeds over 1Gbps, the MB8600 has the bonded Ethernet ports which will allow the MB8600 to deliver speeds above 1 Gbps. We are not aware of a consumer-home/small office router that does Ethernet port bonding today, but they are coming. Ethernet port bonding is available on Enterprise level routers (routers used in large organizations), but we can't recommend that class of product for a consumer at this point. They are more complicated than you need and more expensive. Bonded Ethernet ports for consumers will appear by the time Comcast is ready to begin delivering speeds above 1Gbps and the MB8600 will be ready to deliver those speeds.In summary: Use at least an AC1900 wireless router Be sure the router you choose has a Gigabit Ethernet WAN port.
Question: Does this use the now-notorious Intel Puma 6 chipset
Answer: Model MB8600 and all Motorola products use Broadcom chipsets and do not have the problem associated with the Puma 6 chipset.
Question: Do all four Ethernet ports on this modem output the same amount of bandwidth or are there only certain ports that operate at maximum capacity
Answer: The reason for four ports on a modem requires some explanation. It is important to understand the MB8600 does not do routing. The MB8600 is a modem only. A router can be connected to any of the MB8600 GigE ports. The link between the router and the modem is then capable of using the full rate of the one Gbps service Comcast currently can provide with their new DOCSIS 3.1 service. In the future, Comcast and other cable services are expected to offer services faster than on 1 Gbps. When those faster services are offered, the additional ports in the MB8600 will be needed. Ports 1 and 2 can be bonded to allow up to 2 Gbps to be delivered by the MB8600. The other two ports on the MB8600 are there to allow additional port bonding for speeds over 2 Gbps. When Comcast has service speeds over 1 Gbps, the router connected to the MB8600 also needs to do port bonding to take advantage of the port bonding in the MB8600. Routers used by consumers today do not support port bonding. Some routers used in corporate networks do support port bonding. In the future, routers used in homes and small businesses will be sold that support port bonding so they can take advantage of future service speeds that will be faster than 1Gbps. In summary, the four ports on the MB8600 are there to allow the MB8600 to deliver service speeds above 1 Gbps WHEN THOSE SERVICES ARE AVAILABLE. That is good design. Think twice before you buy a modem that pretends to offer speeds above 1Gbps and does not have multiple ports that can be bonded. You can not get a speed above 1 Gbps unless you have a way to get the fast speed out of the modem. The MB8600 is designed to allow speeds above 1 Gbps to be delivered to a router with bonded GigE ports. Other modems are not as well designed.

User questions & answers

Question: How easy is set up on this device? Would I have to call my provider (Comcast
Answer: It is super easy to set-up, however you usually have to contact comcast with any new device because they have to put it on their system. I basically plugged it in and called comcast, they found the device on the network and I was up and running. The only other step you need is to go into the device setup (the ip address is on the label) and login and set up your username and password for your accounts. There are other settings you can set, but for a basic setup that is all you need to do.
Question: What is the difference between this one and the $89.99 that you also offer
Answer: The MG7550 is both a 16X4 modem and an AC1900 router integrated into a single unit. The MB7420 is a 16X4 modem, but does not include an integrated wireless router. The $89.99 MB7420 would typically be used with a wireless router. The MG7550 has a very powerful router built in.
Question: Is this a 32 band modem
Answer: The MG7550 supports the 250 Mbps and 300 Mbps services which are the fastest offered by the major service providers using DOCSIS 3.0. The MG7550 does not support 32 channels down, but as a caution, 32 channels is not likely to buy you anything more. The next major cable modem speed increase will use a technology called DOCSIS 3.1. That new technology is at least a year away for most people and will be a premium-priced service. The major cable service providers are very unlikely to use more than 16 channels for DOCSIS 3.0 because that would not be an efficient use of their networks. So buying a DOCSIS 3.0 device with more than a 16 channels down is not likely to buy you anything.
Question: Sellers keep saying the range is excellent. what exactly is the range for this router? numbers please. i need facts before i invest
Answer: The range you will get is highly dependent upon what kind of building you are in and how many other wireless signals are in the area. The range you will get in an apartment with concrete walls is much different from the range you will get in a suburban house with drywall interior walls. Results are also highly dependent upon what client (notebook, tablet, phone etc.) you are using. There is an independent study by Netperian that compares the speeds and range of competing AC1900 cable modem gateways. Various building types are used in the test and speed ratings were taken in each room of the buildings. The results were that the Motorola MG7550 is MUCH better than Arris and significantly better than Netgear. The report is over 40 pages long, so you will readily see a few numbers for range are only partial information. With all of that said, in an open field the MG7550 averaged 214 Mbps download speeds at 1000 feet and 475 Mbps at 100 feet. Those were much better data rates than Netgear or Arris with identical conditions.

User questions & answers

Question: Cm600-1aznas ($89.99) vs cm600-100nas ($109.99), what's the difference
Answer: 1aznas is an amazon sku, 100nas is the retail sku. Otherwise they are the same modem.
Question: Does this modem have a router built in
Answer: NETGEAR Gigabit Cable Modem 32x8 DOCSIS 3.1 Max speed 6 Gbps | For XFINITY by Comcast and Cox. Compatible with Gig-Speed from Xfinity (CM1000-1AZNAS) This model, nope, that's a no router model and the one Ethernet port is indicative of that. Netgear does not make any Cable Modems are dual units if there is only one Ethernet port, that's the point, no router, if there is a router, there's at least two ports. And the liars here, says up to 6 Gbps, with one single 1 Gbps port, that's a defined 1 Gbps port and there's only 1 so no bonding. Anything that connects to THIS cable modem will only ever, ever, ever be able to max 1 gb up or down, and we know you'll never see that speed but Cox Gigablast, yeah it's insanely fast. I just don't get why it 100 % is lying and does not ever, under any condition support a connection beyond 1 gb, obviously they are referring to what the cable (coax) is capable of doing per docsis 3.1 but that's misleading, that doesn't matter, it support whatever the slower port is, in this case, the limiting port is actually the Gigibit Ethernet port so that's the max speed 1 Gbps, please correct.
Question: Can the stand be removed
Answer: The stand on the CM1150V can easily be removed by removing one silver screw from the bottom of the unit. For this particular modem you need a Torx-8 screwdriver or equivalent. An earlier review, presumably for a different modem indicated a Torx-9 was required.
Question: Does this device increase the Internet Speed? Why i buy it
Answer: For someone to tell you, "yes"....really doesn't understand how the internet speeds work or do not understand your question. In basic terms....."No", this will NOT increase your internet speed that you subscribe too and pay for. You can't pay for a low internet speed and expect to get fast internet speeds because you bought a piece of equipment. The speeds do not work that way. HOWEVER.....using my current situation for example....I'm a time warner customer. I am paying for the 50 meg speed and I have an Arris 6141 modem. Time Warner just increased all their speeds for free so now I am able to get 300 meg speeds for the same price that I'm currently paying for ***BUT my Arris 6141 modem will only allow roughly 100 megs to get through to me...*** SO I am buying THIS modem because it allows all 300 megs to get through. The internet speed really isn't increased....it's still 300 megs, but by buying a different modem it allows the speed of what I'm paying for to get through. I hope this is a better explanation for you and others wondering about this topic. The answer can be more complicated because of how many "channels" a modem has, ect...but this is a simplistic answer. A modem with 24 downstream channels will allow more speed to get through than a modem with 8 or 16 channels. And a 32 channel will allow more speed to come through than a 24 channel. Allowing more speed to come through isn't the same as increasing the internet speed you have paid for. If that makes any sense.

Question: Does this have a security key on it
Answer: Has WPA key on bottom tag. Has WPA/WPA2 wireless security. Also has Parental Control and Guest Network features.
Question: I have Xfinity blast will I have to call them to install this component
Answer: for me, i just had to connect it to my cable like it was connected. Xfinity website loads and it will automatically read the info off the modem, register it, and even update the firmware for comcast. its done automatically, takes about 10 minutes, and i did NOT have to call them!
Question: does this work with Time Warner cable
Answer: It is not on their approved list yet as of 3/8/2015. I can confirm in the Albany, NY area I have this modem working on Time Warner Cable. I had to talk to a modem specialist to get it working so it was not as easy as an approved device. Read my review for my review for more information.
Question: Can the firmware be updated by the user or only by the isp
Answer: Netgear confirms that only your ISP can update the firmware. This is unfortunate, as the current firmware (at least for Time Warner Cable) relies on outdated code that prevents the Netgear CM500 from obtaining the accurate System Time. This can lead to more dropped connections and difficulty when accessing secure sites. Despite replacing the CM500 with a supposedly updated unit, this error persists. The CM500 consistently reports the System Time as at least 5 hours out of sync.
