Works great
Ok

Purchased used like new. Said box was damaged but it was alread activated under another account.
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.

Absolute garbage product from a garbage company
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.

Didn’t cover good range

Loved the idea of reducing clutter and was very easy to install to only realize that Cogeco doesn’t accept it
