ARRIS SURFboard AC1750 DOCSIS 3.0 Cable Modem Router (SBG6782) Certified with Comcast Xfinity, Time Warner Cable, Charter, Cox, Cablevision, and more (Retail Packaging White)

I bought this modem router for our twins' condo at college. I wanted it to be compatible with their ultra current laptops required by their school of engineering, and I liked the idea of a combined cable modem and router from a convenience standpoint. Initially, during setup, I experienced problems in the setup, since I did not "reset" the unit first to factory specs. Since it was already used previously (I bought this as a used unit on Amazon.com at an excellent price), the former owner had set a unique log-in and password, and did not inform me what they were. But once I reset the box to factory specs, then the initial setup proceeded well and smoothly. After setup, one of my son's laptop was experiencing random disconnects from the internet which was very frustrating. The connection would come and go, and when it went, you would see a yellow exclamation mark on the internet icon in the task bar of the laptop screen in the lower right hand side. But then the laptop would just automatically reconnect to the internet again, and then the random disconnect process would begin again. The other son's laptop would lose connection to the wireless HP Officejet printer. In his case, we would have to "reload" the massive drivers again in his laptop over and over to get the connection reestablished, and then randomly, the problem would appear again. But his laptop (which is identical in model, hardware and specifications to the other son's) would never lose connection with the internet. After much diagnosis and stepwise problem solving, we realized that the sons were living in a high density student environment and that there were many separate internet networks active in the same building and nearby, with many of them operating on the same WiFi channels. In our location, these tended to be channels 11 and 6. Our own modem router defaulted to channel 11. This Arris modem router has a feature once you enter the program inside the modem router to fine-tune it, that allows you to conduct a channel scan of your environment, and allows you then to select a unique default channel other than 11, 6, or 1. We chose channel 9 since no one else was using that channel. Once we did that, then the separate problems each of the two laptops were experiencing went away, and now the laptops have been continuously connected to both the internet and to the printer as well without dropouts. So, the takeaway we learned was to get to know our living environment well first, and then to fine-tune the WiFi operating channel that would avoid competing channel traffic from surrounding networks in our location. Once we did that, our dropped internet connection and dropped printer WiFi connection problems went away. Setup with Comcast internet cable was easy and straightforward, and we were able to activate that modem router easily using the Comcast Xfinity set up program. It was straightforward and automatic, and we are now pleased overall with the Arris SBG6782-AC modem router!

I bought this router primarily based on the product and customer reviews. I wanted to replace my rented cable modem from Time Warner and to set up a MoCA network for my Tivo Roamio and Tivo mini. This is an excellent modem/router once once I got the connection problems solved. I am writing this review to help anyone avoid the pitfalls that I fell into. The model SBG6782-AC has a MoCA network adapter built in, which alone can save you a $75 that you would have to buy with a cable modem that isn't MoCA cable. You will need one Actiontec Ethernet Coax adapter if you have a Roamio (the newer Tivo models have this built in already) and a 2MHZ or faster 2way splitter, and a short coax cable. Setting up the software was a bit of a problem for me. I got the most help from Time Warner - Arris is useless, they will not give you any help (worse yet give you missinformation) in setting up MoCA unless you pay them $30. Well I am cheap and struggled with the installation, getting a lot of help from Tivo and Time Warner helped me too. Here is the information I would pass on to anyone interested in learning from my experience. First find your end point on your cable wires, mine was actually in the outside box, but that is unusual, I am told, normally you will find a splitter in your basement. Time Warner came out free to open the box and install the POE for me, and actually gave me the POE filter for free. The POE goes on the between the splitter and the single wire in. Go to the http://192.168.0.1, use the quick launch. Now this is really fast and easy for getting connected to the internet but it doesn't help at all, I mean zero, with MoCA. For a cable/modem that is MoCA enable, they sure do make it hard for us non-technical people. After you have finished the quick launch, go to the Basic Tab: MoCA Configuration and Status. Check off MoCA enable and set the operational frequency to "SCAN". On the same page select ALL the D-Band Channels. I unchecked the privacy box only because I didn't want to put the generated password into every device until I got my network up and running. Next under the Basic tab again, go to DHCP. Check Enable DHCP Server. The client list (which list every wireless device you have in your home. Now if you already connected your MoCA adapter to your Tivo (skip this on the newer Tivo's). I have a Time Warner Cable network adapter with the Tivo card that I rent from Time Warner. Here is another pitfall to watch out for. Both the MoCA adapter and the Time Warner network adapter need a direct line from the wall. So you need to install a 2MHZ 2way splitter to get that direct connect to both devices, connecting to the Cable-In on both. Cable Out from the MoCA adapter to the Cable in on the Tivo. The cable out on the Time Warner Network adapter is not used. Call Tivo support for great free help in getting the connection just right. The Tivo part of the installation went smoothly, my whole frustration was with Arris, and once I figured out my connection problem everything worked like magic, and my Tivo mini installed with no problems after the Roamio was connected. The modem is fast, secure, makes the MoCA connections easy once you get the software setup for MoCa configure correctly on the SBG6782AC as I described above. The SBG6782AC really is a superb piece of equipment and I am glad I bought it. Arris is formally Motorola, the best modems on the market. Oh I get to return two pieces of equipment that I rent to Time Warner - the cable modem and the DTA device that was replaced by the Tivo Mini saving me $11 total per month. All together a great upgrade that will pay for itself 2 years.

Dropped internet connection......that's what initially was happening when I got this gateway fired up. Having read the reviews both good and bad I weighed my options. For the money the Arris SBG-6782AC seemed like the best alternative to paying the $10 monthly rental fee from Comcast. While it's not ideal to have the modem and router contained in one unit I took a chance because DSLreports said if you must purchase a wireless gateway that this is the product you should get. Here are some things that I did to get everything up and running the way it should. 1. The installation and setup process of the SBG-6782AC went off without a hitch. If you follow the instructions in the quick start guide setting it up is a breeze. With Comcast you can simply plug your computer into one of the ethernet ports to setup and activate the unit. Opening a browser window will take you to the Comcast equipment setup/registration page. From there it's just a matter of following the on-screen instructions. Most importantly Comcast will update the gateway's firmware.....This is very important because you cannot perform this action yourself on this unit. As of 10-16-2016 the most recent firmware version appears to be D30GW-EAGLE-1.5.0.0-GA-07-NOSH. Knowing this is important because there are very few resources available online to tell you if your gateway firmware is up to date.....The manufacturer's web site does not give you this information...(it might but I sure couldn't find it after digging around for a while) An out of date firmware version will cause headaches throughout your network. 2. Not only does the software in the gateway need to be up to date but all your wireless wifi adapters must have their current drives installed too. My laptop has an Intel(R) Centrino(R) Wireless-N 100 wifi adapter that, according to the hardware manufacturer, will not be supported for much longer. I actually found out by mistake that my adapter driver was not up to date. OUT OF DATE WIFI ADAPTER DRIVER SOFTWARE IS WHY MY INTERNET CONNECTION WAS DROPPING OUT. Updating the driver through Windows did not work. Windows was telling me that my computer already had the most current version of the driver software....The date on the most current driver, according to Windows, was from 2011. *******Here is what I did to fix that issue****** (NOTE: Your computer should either be hooked up to the gateway via an ethernet cable or connected with some type of USB wifi adapter so you can still have access to the internet while the built it wifi adapter is being updated) Go to your control panel and bring up your device manager. Select "network adapters" (write down the name and model # of the adapter for future reference) and right click on your wireless wifi adapter then select "uninstall"....Once the wifi adapter is uninstalled, right click on any category in the device manager and select "scan for hardware changes". After scanning for hardware changes your wireless wifi adapter will show up as an unknown device in the device manager tree. Now you need to get online, enter the name of your wifi adapter and do a search for its driver software. Once you've found the correct version of the adapter's software for your operating system (Mine is Windows 7) go ahead and download it.....then install it. This will either automatically update the wifi adapter's software or make it available to you to update the driver yourself. If you need to do it yourself just right click on your adapter's name in the device manager tree and select "update driver software"....It *should* find the new software and install it without issue. AS IT TURNS OUT THE NEW VERSION OF THE WIFI ADAPTER'S SOFTWARE WAS 4 YEARS NEWER THAN WHAT WINDOWS WAS TELLING ME WAS ALREADY UP TO DATE. If you are having problems with dropping internet connections give this process a shot......I accidentally found out that this is what the problem was. Maybe I can save you some time by pointing you in the right direction. 4 stars for the equipment which works very well even all the way out to my man cave (shed) which is 100 feet away from the house out in the backyard....Minus one star due to the fiddling around that I had to do to get everything working properly. I consider myself very tech savvy but if you are having dropped connection issues it can be time consuming trying to get all the little bugs worked out. Hopefully my review can save you a lot of the time that I put in getting things working smoothly. UPDATED SOFTWARE IS VERY IMPORTANT FOR THE OPERATION OF THE SBG-6782-AC. Update 11-3-16: My connection speeds were pretty poor with the wireless N card in my laptop. I swapped out the card with a dual band model and my speeds increased significantly. The router really moves along in the 5 Ghz range. The gateway has worked flawlessly for a few weeks now.....It's never needed restarting and has never dropped the internet connection. If you keep your drivers up to date I suspect this product will function as advertised. I am very happy with my purchase.

I have had two Motorola Surfboards through the years, and, they actually still work just fine. But I like to upgrade for the best experience. I decided to use comcast again, so this works perfectly with them. This worked right out of the box. I literally plugged it in, attached the cable, and have at least 10 wireless devices connected all over the house with amazing speeds. I'm averaging about 115-120mbps and that is well above what I should be getting for speed. So I know this is boosting the connection since I had the previous versions to compare. Let's see, iMac, iPhone, iPad, Kindle Fire and HDX, Amazon Fire TV, Roku 3, Chromecast, Sharp HDTV with apps, Playstation 3, Blu-ray player with built-in apps, HP PC Laptop, MacBook Pro, Kindle Paperwhite, Tivo, Bose wireless stereos and speakers, etc. I'm sure there is more. Point is, I have everything running all at once at times and never had such a seamless connection experience. It has been a pleasure using this the past few weeks. The unit itself is rather large, but well ventilated, and never hot, or warm for that matter. Their are four Ethernet ports, and I have my old Ooma phone unit connected to it for free phone service. I put an old Tivo into one of the ports too and it's working fine. When connecting your wi-fi stuff, you will see two options to choose from due to the 2.4 GHz and 5.0 GHz dual-concurrent connections. Select the one ending in 5G for the best experience. Really has been no reason have cabledue to HDTV being free and the existence of Netflix, Hulu, Amazon Prime TV, Vudu etc. But I opted to throw on HBO as it was free for a year. And I like it mainly due to HBO GO, basically their version of Netflix. All controled with my iphone or ipad sent to my TV as a remote via wi-fi. No need for that huge thing that comcast gives you. Streaming Netflix and especially Hulu is so much better. Hulu was seriously bad for a while, but it's a whole new world with this modem. If you want the best without headaches, get this one. I am clearly a Surfboard fan-boy.

This thing does what it's supposed to about 90% of the time. Yeah, its' easy to program with an intuitive interface. Yes, it's sturdy and doesn't overheat. Yes, the Wifi is super solid and runs dual bands simultaneously. It's The Rolls Royce model for a Rolls Royce price-tag. That's the problem. If you spend over 200 bucks on a wifi router/modem combo you expect the the thing to work. About3 times a week it will drop internet or local network access (rarely both, oddly) for some or all of my devices. Nothing I seem to try will reconnect other than a hard reboot of the Motorola unit, which you cannot do from the interface. You have to unplug it,,,sometimes 2, 3, 4 times. This is a typical occurrence: My Media Computer will just lose access to my local network out of the blue. Internet access works, but nothing local. So I curse. I try a lot of different things, eventually I give up and unplug the unit. After plugging it back in I now can see the local network, but no internet! I just have to keep rebooting the thing and crossing my fingers. It got especially squirrely when I started using a VPN occasionally. There have been times where I had no intenet access until I ENABLED the VPN, which makes no sense to me yet. Other times have been the exact opposite. The other crazy thing is that all these local network blocking is being done between computers that are hard-wired to the unit. The wifi doesn't even come in to it. for the most part the wifi itself is stellar. I'm using DHCP with reserved addresses for the hardwired computers currently, but I've tried just about every configuration and I find no pattern to the failures. Incidentally, it may not be Motorola's fault entirely. This is being used with Comcast cable and I understand that they flash whatever firmware they like during the initialization. That's not much of a comfort to me at this point though. If I had to do it over again I definitely would not purchase this unit. It works no better than the cheapest units. *Edit - Ten minutes after writing this review I noticed that the router had again dropped out the local network. I restarted the router 4 TIMES and after the fourth time the router finally allowed data traffic across my local hardwired network. I think it's getting worse. *Edit - Posting this a few months after the last update. The cable company put out a firmware upgrade (that's one problem, typically your cable company determines what firmware you can run) and the drop-outs seem to be better. I haven't had to restart the router in about 10 days which is a record.
