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:	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:	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:	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:	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.

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.

User questions & answers

Question:	Is this router quiet/almost silent

Question:	Is this router works with verizon fios
Answer:	No
Question:	Do i have to use "smart connect," or can i choose for myself which band i connect each device to
Answer:	As long as the device you're trying to connect can see both bands, you can connect to either one.
Question:	can a phone line be added to this unit
Answer:	There isn't a phone jack, per se, but you can use any Ethernet service like Obi200 (provided they don't do any 'Mandatory upgrades' Shenanigans, again) and Google Voice. It works perfectly, just you gotta use ethernet and not phone line/Cable company provided Junk.

Product description

The Zoom Model 5345 is a 343 Mbps cable modem certified for money-saving own-your-own cable modem programs by Comcast XFINITY, Time Warner Cable, and other leading cable service providers. Charter Spectrum approved. Owning a certified own-your-own modem eliminates modem rental charges that are typically $8 to $10 dollars per month. The Model 5345 Gigabit (10-100-1000 Mbps) Ethernet port connects to your Windows or Macintosh computer, router, wireless access point, HomePlug adapter, or other Ethernet-enabled device. When used with a router, the high speed Internet service can be shared with multiple devices. The number of channels supported by a cable modem is the primary indicator of a modem's top speed. This modem is 8x4, which supports eight channels for downloads, and four channels for uploads. Eight channels for data downloads make this modem up to twice as fast as competing modems that support only four channels. Because this 8x4 modem uses the cable network more efficiently, average download speeds can be faster, even for service speeds below the modem's top speed of 343 Mbps. A Full-Band Capture Digital Tuner lets service providers deliver faster, more reliable Internet. The 5345 is certified by CableLabs to support the latest DOCSIS 3.0 standard plus DOCSIS 2.0 and 1.1 for use with older cable systems. IPv6 and IPv4 are supported for powerful, flexible network addressing. With its easy installation, high speed, compact size, and extensively tested compatibility, the Model 5345 is the perfect choice for almost any cable modem user. The Model 5345 has been tested and certified by CableLabs to work with nearly all U.S. cable services. The Zoom 5345 is covered by a two year warranty and quality technical support by Zoom Telephonics, a Boston based company founded in 1977.

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.
