User questions & answers

Question:	My family has two appartments next to each other, both separate electrical installations. Would this work if we wanted to split the internet bill
Answer:	Yes the EX8000 used as a wifi extender you have the option of having a guest network. You can use same SSID name as your main router or use a different SSID altogether. I did have issues with more than one extender on the same network using same SSID name as main router so I had to change one of the extenders to a different SSID.
Question:	Has anyone connected a ps4 of xbox one to the wifi from the range extender? if so, signal and game play any good
Answer:	If you mean an AT&T router signal, yes. If you mean cell tower signal, then no.
Question:	Does it create a new sid or does it exteneded your current sid, so one does not have to switch to differing networks when in range
Answer:	the input voltage is from 100 to 240 volts
Question:	I don't understand how some people give this 4-5 stars and others can't get it to work and give it 1 star
Answer:	there are 4 ports. I use multiple ones as this is the only system I can find that does not change the network name but once a year I also have one break and have to replace it or hard reset it myself.

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:	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:	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:	When are where will this be available
Answer:	It is now available on Amazon.
Question:	I’m stuck between the this and the Netgear cm
Answer:	Here are my impressions. I recently purchased the Motorola and it is performing as expected although set up with Xfinity was a bit frustrating. I have used Netgear equipment in the past and been happy with it. I believe the CM1200 is a little bit older technology than the MB8611 and more expensive. But either of these modems should serve you well.
Question:	Does this include Xfinity voip service
Answer:	No, but if you want that, just add a VoIP box (about $40) and a service (about $20/mo.).

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:	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:	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:	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.
