ARRIS SURFboard SBG7600AC2 DOCSIS 3.0 Cable Modem & AC2350 Wi-Fi Router | Approved for Comcast Xfinity, Cox, Charter Spectrum & more | Four 1 Gbps Ports | 800 Mbps Max Internet Speeds 2 Year Warranty

The SBG7600AC2 works great with Xfinity, and setting it up was a simple phone call to Xfinity support. They asked for the MAC address from the back of the modem and it started working almost immediately.Logging in and going through the config menus is pretty straightforward. It is pre-configured enough that you don't even have to log in to start using it but when you inevitably want to customize things the menus are well laid out. Well, mostly... One thing I definitely do not like is the "Operation" tab at the top of the menu. Clicking it takes you out of the nice, polished looking interface to a clunky ascii look interface. On top of that you have to log in again because it is a completely separate interface on the modem. On the 6700 the info could all be accessed from the admin page, not sure why they had to break it up here. It's a minor complaint though, in an otherwise solid interface.I got the SBG7600AC2 to replace an SBG6700AC at the same time as I upgraded my Xfinity service from 300Mbps to a 600Mbps package. The 6700 only has 8 bonded download channels which theoretically maxes out at 343Mbps while the 7600 has 32 bonded channels and maxes out at 600Mbps. The old modem pretty consistently got 150Mbps download, the SBG6700AC gets nearly 500Mbps download using the speedtest website, a huge improvement. It's not the 600Mbps my package claims but I attribute that to the fact that I have 6 computers, a couple of tablets, smart TVs, phones, etc. all hogging up bandwidth.With 4 - 1Gb ethernet ports, 2.4ghz and 5ghz wifi and file sharing + media server capabilities from the built in USB, this is a really solid modem.

Great unit, setup was easy I called comcast when I put in my order for internet and gave them the MAC address ahead of time. Because I have no cell service only wifi calling at the location I installed this unit too I wanted to make sure they had all the info setup ahead of time . So I showed up to where I was installing this which was my remote camp. I connected my cable plugged it in all the lights went solid blue! Perfect! Than to verify with comcast like they make you do I took a laptop connected to the default wifi network the unit was broadcasting. It Connected perfectly. Than I Opened a browser the Comcast setup screen was right there. I logged on Comcast it said successful and to wait while modem reboots. It rebooted twice and bam all done. Easiest new setup I have ever done! I subscribed to comcast 400mbps plan and my download on the 5ghz channel is consistently between 460-480mbps. I attached and image of my speedtest results Lightning fast! Wifi range is adequate for me and better than my previous router. The arris setup is easy to get to by going to 196.168.0.1. Log in And its all there. Whatever issues people had provisioning this model on comcast are now a thing of the past. Setup was easy, speed is better than what I bought , wifi range is excellent and the router settings are easily accessible. Overall 5 stars!

I will say the modem arrived as an open box item (tamper seals or stickers were missing) and it was shipped in original package, not an Amazon or plain box. However the modem looks brand new and works as advertised. We have a small home but the wifi range is adequate for sitting outside and staying connected. (I've been told the 5G setting/network on the modem is for greater distance outside the home, but haven't really tested it). Download speeds are much faster now (like A LOT). We've never had a connection drop yet. It meets all of our gaming and streaming needs. I've owned an Arris modem before and never had any issues. If you're like me, reading reviews and trying to decide, I would recommend this modem. We've had it 3 months and no issues. Time will tell, but my last Arris modem was still working after 5 years.

I have had nothing but problems with this modem and router since the very first day I installed it.1. My Television which is in the living room about 50 feet away from the router, no issues...connects perfectly; however, my wireless printer which is less than 3 feet away...losses connection ALL THE TIME. Working from home is difficult when I never know if I'm going to have a connection.2. My devices often loose connection for no rhyme or reason. Again, my Echo Dot in my bedroom (about 50 feet away works, most of the time,) but the one in my office about 10 feet away losses connection.3. I have never changed my password on the device, using the password provided; however, recently when my Echo lost connection and I tried to "reconnect" I am getting a message that the password is invalid (mind you, I saved the password to the device, which worked fine for a few weeks. Even when I manually type in the password, it states it is incorrect.4. The Surfboard app is the worst. Nothing but issues, does not recognize my device, states my username and password are incorrect (even though I wrote them down when I first installed the app, and there is no way to reset it.) And now, I am sitting right next to the modem, the app cannot find a signal (all lights are one and my computer a few feet away is connected with no issues.DO NOT BUY THIS PRODUCT. I NEVER write poor reviews, but after spending close to $200 on this, and having nothing but problems fro close to 3 months now, I cannot let anyone else deal with this. The cheap Linksys modem I had (under $50) works so much better than this,SAVE YOUR MONEY AND SAVE THE HEADACHES.

Works nicely with spectrum cable service in Florida where they replaced their Ariswith garbage. The software they provide to configure the unit is outstanding. You call up spectrum and tell them to activate it and they will. If you need all the bells and whistle, this is definitely the way to go. This particular unit is second to their best one. I would get the next step up next time. It’s only a few more dollars. They claim it’s faster. Although this is plenty fast. Oh, and outstanding customer service.
