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
Answer:	3 things I can tell you. 1. The 7621 is 24 x 8 channels vs 16 x4 for the 7420. More channels means better flow of the data. 2. The 7621 can handle 1000 Mbps vs 643 Mbps for the 7420. 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.
Question:	What chipset is the mb7621 utilizing? intel or broadcom or other
Answer:	Model MB7621 and all Motorola modems utilize the Broadcom modem chipset.

User questions & answers

Question:	Why does it say 4x ethernet ports in your description where there is only one
Answer:	Because Amazon hasn't corrected their product subscription. I submitted one two weeks ago and has yet to be done. If you need more than 1 ethernet port, then this one is not for you. This has only (1) 2.5 Multi-Gig port.
Question:	Does netgear cm500-1aznas work with tds provider
Answer:	Yes. But you need to call the TDS customer service and provide your CMAC or SN to register your device. These numbers are on the box and the unit
Question:	Can you use a phone to ethernet splitter for voice to work
Answer:	I have never heard of a phone to internet splitter, at least not expressed in those terms. However, for VOIP (which means Voice Over Internet Protocall), you must have at least one phone jack in a modem, or a modem-router combination. Some modems have two such jacks, which could provide two different "lines." Most importantly, you must have your internet service provider's PERMISSION to install and use such a modem, or modem-router combination! My own ISP (Wow, aka Wowway.com) REFUSED to give such permission because that would cut into their profits, since they would no longer receive a monthly FEE to RENT their age-old junk, much of which are at least five years old, which is like a millenia in this day of super-fast-paced electronic offerings. I had to send back every VOIP-capable modem I bought from Amazon and other places because my ISP REFUSED to enable them to work with their so-called service(s). Talk about anti-competitive business practices ... U.S. Federal Trade Commission (FTC), are you paying any attention?
Question:	I understand that this modem says it will only work with xfinity. but has anyone tried this with spectrum? (aka time warner cable
Answer:	Hello. I am writing this Dec 2, 2020 and just activated this modem 2 days ago with Spectrum. It is not on the list of approved modems, but oddly enough the CM400 is. I just told the tech support who activated it that it was compatible and it's worked fine with no problems. I went from 100-120 mbs on my 100 mb plan to 250 to 450 mbs, still on the 100 mb plan. This modem is not on the list of approved models but it seems to work fine so far without periodic latency/drops like the Arris model from Spectrum had.

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 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.

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:	Can I connect it to my computer for Ethernet connection
Answer:	yes. It can if you have Internet service as part of your cable package
Question:	Does this work with RCN cable/internet service
Answer:	Only RCN can answer that question. I can say that this modem will handle at lease 110 Mbps because that was what I had. It did not handle 300Mbps. The modem worked perfectly and was very reliable.
Question:	What kind of router is best to use with this modem
Answer:	That is a very hard question to answer in a limited amount of space. First, think about getting the Model MG7310, which incorporates an N300 wireless router. You will probably save some money and you will reduce cable clutter, increase reliability (wiring connections are a frequent source of trouble) and save desk space by incorporating both modem and router in a single device. If the MG7310 won't work for you, here are some very general rules, but the choice of a router is definitely an individual decision that has to factor in price and performance. If you are in a dense setting like a high rise building or a dense condo or apartment complex, get a dual band wireless that has both 2.4 GHz and 5 GHZ frequency support. But that assumes your connecting devices like phones and computers support 5 GHz. If you live in a very large house, or a house with masonry walls rather than sheetrock, you will want WDS support in case you need to use a range extender. With that said, if you have a 50 Mbps cable service or slower, an N300 router will probably meet your needs and save you some money. Much more could be written on this topic, a search of the Internet should provide additional information.
Question:	Do I need to contact my cable provider that I am changing my previse cable modem for this one, or will it work out of the box
Answer:	Short version: Use your provider's self registration website, or whichever of their customer service methods work best for you. Long version: The cable modem will go online once powered and connected to a coaxial cable with good signal parameters. You still need service authorization from the cable modem termination system. Some cable internet service providers have self registration websites. Connect the coaxial cable to the modem, an ethernet cable to a computer, and connect the power cord to an outlet. This may also work over a wireless router and with wireless devices, but just using a computer can help isolate any setup issues. When your modem first goes online, the CMTS may recognize a foreign modem and direct your web browser to the registration website. If not, the registration website can be manually searched for, which is where a secondary internet connection of some sort can come in handy. If you have your account information already, the only other thing you may need to add is the CMAC, or Cable modem Media Access Control address. Some registration systems can detect this automatically. This is the number that distinguishes your modem from all of the others, and should be on the modem if not also on a label in the box. At the end of the process, the modem will probably restart on command of the CMTS. Once it is back online, test your internet connection. You may need to power cycle the modem (unplug it and plug it back in) or reset it (hold the reset button for long enough) before using it with other equipment, most commonly a wireless router. This particular product is just a modem, so if you previously used the wireless network coming out of the cable company's equipment, you would also need your own wireless router or other networking equipment. This whole process can often be done ahead of time and the new modem plugged in later, but be advised that the previous modem (if it is still online) will lose its service. Also be aware that if the wiring leading to an old modem has issues, changing modems will not fix the real issue and is not likely to make the service any better.

User questions & answers

Question:	Does this have a wifi on/off button
Answer:	Not a stupid question as visitors with EMF sensitivity need the wifi turned off and unplugging is not convenient.
Question:	Will it broadcast in both 2.4 and 5 at the same time
Answer:	Model MG7550 will broadast in both at the same time.
Question:	What is the difference between the mg7540 and mg
Answer:	The MG7540 has AnyBeam beamforming for only the 5 GHz that will focus the signal on wireless clients to allow better performance and range The MG7550 has AnyBeam beamforming for both the 2 GHz and 5 GHz frequencies which focuses the signal on wireless clients to further enhance performance and range. The MG7550 also has the capability of wireless Power Boost which adds high-performance Wi-Fi power amplifiers to boost the wireless signals to the legal limit, giving a significant boost in speed and range.
Question:	How difficult is the configuration process
Answer:	There wasn't much to the setup. I took the modem/router out of the box and connected it to the cable/internet wall plug. With Comcast I was able to do the setup over the internet (using my phone). It only took a few minutes over the internet versus calling Comcast.

Connect All Your Devices

The built-in router provides high-speed shared Internet access to smartphones, HDTVs, computers, tablets, game stations, streaming media devices, and other Ethernet and WiFi devices.

Better WiFi with AC1600 Dual Band

Dual band gives you two WiFi networks operating simultaneously in the 2.4 GHz and 5 GHz bands. Single band routers only use the 2.4 GHz band. This band is often full of interference as all your devices share that single band with your neighbors. The 5 GHz band in dual band products is typically much less crowded and has less interference. The bottom line? Dual band delivers much better WiFi.

Beamforming

AnyBeam WiFi beamforming at 2.4 GHz and 5 GHz focuses the wireless signal on your wireless devices to further enhance wireless performance.

Clean and Easy

Integrating the modem and router saves space, reduces wires and power cubes, and provides a single user interface.

User questions & answers

Question:	I bought this modem & my Linksys wireless is too old to handle the speed. Can anyone recommend a good wireless router to go with this? for home use
Answer:	It works really well with my new time capsule! Details on time capsule here: http://www.apple.com/airport-time-capsule/
Question:	Is this compatible with Time-Warner cable and will this work with Google Voice? Can i use the Netgear 7550 for its router
Answer:	I live in Queens New York, and I have this modem for a few months with time warner cable . I got 100 Mbps with no issues using the Asus Wireless Router .That's what I paid for, I don't know if we the modem can take the 200 or 300 Mbps. It will work with Google voice
Question:	Any advice on the steps to set it up? Is the serial number necessary? (I am having Comcast
Answer:	I have Comcast and the SN is necessary to get it setup (call them). Mine had the SN blacked out so I had to plug it into a computer, then use a browser to see the SN by logging into the admin screen (192.168.0.1)
Question:	will this work with comcast (xfinity) hi speed internet & vonage home phone? thanks
Answer:	I bought it specifically to replace the comcast supplied modem after I terminated my landline. It is supposed to work with comcast hi speed internet, but it performed poorly. I returned it and replaced it with the equivalent Motorola model which has been far superior in performance (cost about $20-30 more.) I suspect that this model works better with satelite, but this is merely speculation. I would not recommend it.

Answer:	Yes it is! It has dual functionality. If you have a router you like already you can turn the wifi part off and just use it as a modem

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.
