Surfboard SBG6950AC2 DOCSIS 3.0 Cable Modem & AC1900 Wi-Fi Router , Approved for Comcast Xfinity, Cox, Charter Spectrum & more , Four 1 Gbps Ports , 400 Mbps Max Internet Speeds

Works well. Easy to set up. I had issues but that is on my internet provider's fault. This modem has been working well for 4 days now. Will update in the future if anything happens. Update: It's been like 5 months now. I've been using internet via this thing without any issues. One thing I gotta say is my internet service is 50mbps, way below the capability of this modem router, so I cannot comment in term of max speed. I do get all my 50mbps. I have Xfinity. This device has been very reliable with my current service. I never had to restart the router due to drop connection in the past 5 months. (I had this issue a lot in the past, not sure if due to other modems/router or due to my previous internet services.) This device got 5Ghz wifi which allows me to play Xbox games from the cloud. In short, great device, I'm glad I bought this. I actually bought a used one here for maybe a third or a quarter the cost of a new unit

Ok

It's been almost 9 days since I replace my clunky, big, hot Spectrum Internet modem with this Arris modem. My Internet connection has not dropped once since I connected it up. With the Spectrum modem it was dropping almost every day (which if you work from home is a real pain). Setup was super easy. Moved the 2 cables from my Spectrum modem to the Arris, called the cable company and asked them to activate the modem. Took less than 10 minutes for the whole thing. NOTE: 1. Change the password on the modem as soon as you set it up. Very important! 2. If you have another device at home that provides wireless connectivity, like I do, disable the wireless connectivity on the modem - you don't need it - and it protects you from drive by wireless hackers (they are out there). You will see the 2 wireless lights on the front of the modem go out. So far, very happy with this purchase. I will return my Spectrum modem, and most likely my Spectrum cable box too. Spectrum is constantly raising prices - it never ends - and I rarely watch cable TV anymore - it's all crap. I have transitioned to steaming TV, and no longer need the cable company for TV.

Purchased "used like new." Said box was damaged but it was already activated under another account. I always but warehouse deals since they are usually new items with messed up packaging. Not this time. The modem could not activate. Why? It was previously used on another account. Since logs show that it was only powered up for ten hours max they were able to clear the previous user and password and make the modem usable. It works FANTASTICALLY!!! Speeds were previously hovered around 20-40Mbps and would drop constantly (5 year old modem), bot it is rock solid and fast. 140Mbps average. Still not happy that it was not listed as previously used instead of "damaged box." I the end it was a good item for a good price for a little headache.

I purchased this modem around a year ago in May of 2020 and it's one of the best routers I've used. I work as a network and systems administrator and I'm nerdy enough that I've built my own home network with multiple VLANs using the arris as my gateway. I've only had 2 main issues. 1. It doesn't always play nice with the upstream/downstream power of the connection and I've had to use attenuaters at 2 of the 3 addresses I've used it at. 2. There were times when I had bandwidth issues and other intermittent connectivity when using the wifi but that was before I put all of my IOT devices on a 2.4GHz guest network as well as spreading out the load with my other devices on the appropriate 2.4 or 5G bands (or Ethernet of course). The router interface is a little clunky and doesn't allow you to rename devices that I've found which isn't ideal but it's not a hill I'm willing to die on. I would like to eventually upgrade to a better Arris Surfboard model and use this model as an AP/Router to further even out the load of my network. If you are having connectivity issues with this router the 3 main issues to look into are: 1. If you need to attenuate the stream 2. IOT devices causing interference on high traffic areas and bands 3. Good old ISP might just be pulling a fast one on you and throttling. Worth calling ISP support and Arris support to trouble shoot these issues. Very happy with this router and I will never rent from an ISP company again. I've never worked with an ISP rented modem that didn't give me months of headaches.

tl;dr: This product failed after two months and Arris makes it nearly impossible to replace it under the warranty. I bought this modem to replace another Motorola/Arris model that had served me well for several years. The modem installed easily enough with Comcast, though it was a bit confusing since there are two MAC addresses on the bottom of it, and it wasn't clear which one to use. So, I had to go through the install process twice. Configuration is pretty easy using the included web interface, so no complaints there. The WiFi signal seemed pretty strong, too, although I ended up adding an access point in the upstairs of my house because it couldn't quite reach my home office. The modem worked great for about two months. But then about a week ago, my network started dropping out and I would have to reset it multiple times per day (even though the lights on the modem indicated a working connection). (Note: there are a lot of other reviews on here saying the same thing has happened to other people.) Not only that, but my home network would go down, too. The router was basically freezing up. Obviously, even if Comcast was having a problem on their end, that shouldn't bring my entire network down, right? At this point, I tried a factory reset, but the same thing kept happening. So I called Arris tech support. Long story short, Arris tech support blamed Comcast (saying the signals were too strong), who in turn blamed Arris (and laughed at the notion that they could just "turn the signals down" per Arris' suggestion). I even put a splitter on the line to get the signal power within the proper range, but it kept happening. The Arris tech tried to blame the wiring and said that I needed to have a technician come out. I pointed out that I would have to pay for that, and that Comcast would likely tell me everything was fine (I have fairly new wiring and very reliable, fast speeds up until last week), and even then, that wouldn't explain why my internal network kept going down. I asked him what exactly it would take to convince him that it was the modem, and he refused to answer, other than to say we would have to do more troubleshooting. (And honestly, what more troubleshooting can you do other reset it?) At this point, I had spent a couple hours on the phone with Arris and Comcast, and I just gave up (which I think is what they intended) and bought another brand of cable modem, and things have been working fine thus far.

It was super easy to program and set up. It really helped us with the lag we were getting before! Now smooth stream!!

hasn't stopped since I put its into use - always performed and freed me from the 'equipment rental' charges for good!
