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:	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:	So how do control the cable modem if comcast doesn't provide one

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.
Question:	What chipset is the mb7621 utilizing? intel or broadcom or other

User questions & answers

Question:	What does "AC1200" mean
Answer:	AC means that the router has support for the 802.11ac (or Wi-Fi 5) wireless networking standard, which offers fast WiFi network connections on the 5GHz frequency. 1200 means the max Mbps is 1200
Question:	Does the box come with the necessary cables? (e.g. power cord and coax cable
Answer:	It does come with a power cord and either net cable. A coax is not needed since cable company should connect their end directly to the modern.
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:	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.

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:	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:	Will this work with charter spectrum? Cable tv
Answer:	Yes I called the seller they told me that this modem will work with Spectrum cable Tv.
Question:	Where do i find the devises user id and password
Answer:	It's printed on a label on the modem itself.
Question:	Will this work with optimum
Answer:	It’s Amazon... buy it and if it doesn’t work, return it.
Question:	I bought and finally connected. I can only get 1 of the 4 ports to work at any given time. It doesnt mater what port I plug in 1 works other no
Answer:	The additional 3 ethernet ports are reserved for port aggregation, which is currently not supported on the CM1150V. I guess you would call them reserved for future use. The CM1150V does not include built in router. Most ISPs, like Xfinity only provide a single IP address with your service, so you would not be able to get multiple computer or other network devices to work without a router connected your modem. What you would need to do is connect a router to one of the ports on the CM1150V, then connect your devices to the router.

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:	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.
