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

I’ve been using the ARRIS SBG7600AC2 for just over a month now, and I can confidently say—it worked great from the moment I set it up. This all-in-one cable modem and router combo has been a solid upgrade for my home network. Installation was straightforward, and it synced with my Xfinity service without a hitch. Within minutes, I was up and running with fast, stable internet. The DOCSIS 3.0 modem technology combined with AC2350 dual-band WiFi gives me reliable speeds throughout my home. Streaming, gaming, video conferencing—everything runs smoothly, even with multiple devices connected at once. I consistently get speeds near the 800 Mbps max (as advertised), which is impressive for a device in this price range. The four 1 Gbps Ethernet ports are a great bonus, giving me flexibility for wired connections to my desktop, gaming console, and smart TV. It’s also great not having to pay monthly rental fees for ISP equipment anymore. Overall, this is a dependable, high-performing modem/router combo that delivers fast internet speeds and wide WiFi coverage. If you’re looking to simplify your setup while boosting your home network performance, the ARRIS SBG7600AC2 is absolutely worth considering.

I started using this very modem/router in 2019, and loved it. A thunderstorm and power surge wiped it out, so I ordered this as a replacement. I had it up and running in about 10 minutes, and Xfinity logs it in via the phone app. It's super fast, powerful, and has 2.4 and 5 ghz signals. Each of those also has a "guest" signal you can enable, so you actually end up with 4 separate channels. This SURFboard keeps all my smart devices, Rokus, wifi security cameras, computers, and tablets all connected and functioning perfectly. You gotta love the SURFboard modem/router.

Candidly, I'm fresh off an unsatisfying support chat with Arris, and pretty frustrated, so they get 1 star. When the modem/combo router works, it's great. But mine started to fail after 9 months. It would restart or crap out 2-4 times a day. I would have to constantly restart it. The kind of behavior that you might expect from a router that is 5+ years old. It was within their 2 year warranty, so I contacted support. The first time I spent about an hour doing some troubleshooting steps and changing the Wi-Fi channel from Auto to Manual, to try to avoid interference from other devices in the area. I was hopeful this might address the issue. As another step, I also updated my DNS to use Cloudflare's instead of my ISP. Neither of those issues worked, so I went back to Arris. It took me over 2 hours to get a replacement claim going. It would take about 2-10 minutes between each message to receive a response from support. e.g. "Would you like me to start processing a claim for you?" "Yes" 5 min later "Ok, I will start processing the replacement" "Can you confirm your first and last name?" "Can you confirm your email address?" - rinse and repeat. I'm pretty sure the whole process is designed to make people give up out of frustration. Arris provided two options Standard Replacement and "Advanced." You can probably guess what the difference is. Standard requires you to send your defective product back, wait for them to confirm the return, then send you a replacement. i.e. you'd probably be without a router for 2-3 weeks. (A defective router that you have to restart 2-3 times a day is still better than no router). With "Advanced" - they send a replacement product while you get to keep your defective one. Once you receive the replacement product, you send your defective one back. Unsurprisingly, with Advanced, there's a fee. You have to pay shipping (which they charge $20 for ground shipping). They also put a hold on your credit card (MSRP - $255, which is double what I actually paid) while they wait for you to send the defective product back. I tried finding a copy of their warranty statement, but couldn't find it listed anywhere. So none of this is explicitly documented anywhere. When I asked for a copy, the support rep took 20min to discuss with the manager.

I have been working with Comcast and Arris over a problem with the download speed. I am getting an average of 338.6 Mbps. For 2 days, I got 763.8 Mbps, right after I upgraded to 800 Mbps from Comcast. The Modem/Router is rated at 800 Mbps. I have contacted Arris support twice. The first time the person did a number of port changes and updates, telling me it should work in 24 hours. I called again today and the support agent tells me it is only capable of 600 Mbps.!!! I am paying for 800 Mbps from Comcast and the Arris agent tells me I need to cut back on the download speed???? I spoke with a supervisor at Arris as I was so upset with the agent. UPDATE: Once I found out the modem wasn't capable of handling the 800 Mbps, I contacted Comcast and changed the download to 400 Mbps. That solved some of the issues I was having with the modem. I am still upset with Arris for allowing it to be on Amazon, showing a rated speed of 800 Mbps.

12/11/25..update. Having many issues with this item. Cannot seem to keep up with tv streaming. We constantly have to re-log in to apps or get told it cannot connect even when it says signal strength is excellent. I honestly don’t know why it is acting up and it course we’re beyond the return period. A good modern/router. Distributed WiFi well through our home. I work from home for a cash center and I experience good phone connection and smooth internet. So far we’re very happy with it and it saves on renting from the cable company. Our last one lasted over 10 years, hoping this model will as well.
