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.).
Question:	Is it worth it to get this over the MB8600 if my router doesn’t have 2.5gbe
Answer:	Yes

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:	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:	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.
