User questions & answers

Question:	is this compatable with belkin routers
Answer:	Yes.
Question:	Doe it work with Century link
Answer:	This modem is for use with Cable Internet, not DSL. If CenturyLink offers cable internet in your area, it should work. I know this modem works with Suddenlink cable.
Question:	Will this modem work with Time Warner triple play internet and their telephone service
Answer:	In my area, currently, if you have Time Warner 'triple play' (TV, Internet, phone) and you have your own supported modem, TW provides the same modem they would for triple play and uses that for phone service only - at no monthly equipment charge - and disables their modems Internet connection/ wifi. So you do need that TW modem in addition to this unit and a cable box for TW triple play, but your only equipment fee if you have your own modem is for the cable box / DVR. I am using this modem and a TW modem with a high bandwidth splitter and good, short coax patch cables (or you can use different cable wall outlets for phone and Internet if you prefer) with TW triple play, and am not charged any monthly rental fee for Internet or phone hardware. Contact your TW representative and confirm their policy for your area (may take more than one call to get a representative who can give you the official answer).
Question:	Will this modem work with at&t uverse ??? if not which modem will
Answer:	No it definitely will not. AT&T Uverse uses modems that have an RJ-11 connector in the back (phone cord plug). This is COAX, and is only used for Cable Internet providers. What you need to look for is a 2Wire or other common Uverse modems. Hope this helps. If you call AT&T they can also give you a list of compatible modems for the services offered in your area.

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:	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:	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:	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.

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:	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:	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:	Will this support xfinity extreme 1200mbps ? it's not on the supported device list
Answer:	The Arris S33 is a DOCIS 3.1 capable device 32 x 8 rated for speeds up to 2.5 Gb. While the modem is indeed on Xfinity supported device list (check detailed discussions on dslreports.com), what matters is your router. Ensure you have a router capable of 1+Gb speeds.
Question:	Is there a way to mount this device to a wall
Answer:	We recommend placing the device on a tabletop in an open space to avoid any interference
Question:	Is this modem compatible with suddenlink
Answer:	It will work at the lower speeds since it is capable of up to 2.5Gb but runs just fine as low as 100mbps/5mbps (down/up) with 32x8 channels. Suddenlink allows ARRIS SB6190 and the S33 is a superior upgrade.
Question:	Can you use both ethernet ports at the exact same time
Answer:	Update...... I have picked mine up from BestBuy and YES you can use both Ports at the same time. I have the 2.5 to my PC and the other port to my Asus Ax11000 router. Hope this helps.

User questions & answers

Question:	Does it include cables

Question:	I have a few pieces of hardware that are only 802.11g still and most others are 802.11n. Can I run 1 band on g and 1 band on n simultaneously
