ARRISSURFboard 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 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.

Purchased this as a replacement for Comcast-supplied xfinity modem to reduce monthly rental fees. I subscribe to Comcast TV and Internet, but don't have Phone service so that didn't factor into my modem decision. Those who want phone can still get this modem but will need a separate adapter to support it.The main reason for selecting this modem over others is the built-in MoCA support. I have coax running to each room and wanted to leverage that with a Tivo mini setup, and Not have to run Ethernet wiring to each room. MoCA is really a great solution, and the Arris modem performs at my expectations.I also added a point-of-entry coax filter at the box where the cable line enters my home and splits off to the rest of the house. I have found this to be critical, possibly mandatory for anyone to get a stable and isolated network. Without the POE filter, signal travels outside the home resulting in signal loss.My setup now is based on TiVO Bolt with a Comcast cable card [which Comcast considers the "Primary set top box" for equipment billing] and 3 Tivo minis, replacing 4 comcast HD STBs and xfinity modem. I've cut my monthly expense significantly, but that's a separate review.Great results - I am streaming live HD TV from Tivo Bolt and to 3 Tivo minis over MoCA. That's 4 active HD streams, with a transmit rate of 245 Mbps - the video is smooth. At same time, accessing WiFi using iPhone 6S at 60 Mbs download (Comcast Blast Internet). Includes a Dynamic DNS feature which will update your own domain name with the router WAN IP address - great for remote access capabilities like web cams.Easy to connect to Comcast - call them up and have MAC address ready - they send signal couple of times and all is good.The router administration interface is a bit clunky and not modern or intuitive. Instructions for remote access were terrible, and Arris Technical phone support was clueless. Needed to google around to get instructions but that doesnt take away from the performance of this router/modem.Would recommend this to anyone with Comcast looking for a straight forward replacement.
