Motorola MB8600 DOCSIS 3.1 Ultra-High Speed Cable Modem | Approved for Xfinity by Comcast, Spectrum, Cox | Supports Cable Plans up to 1000 Mbps

Way better than the Arris Docsis 3.1!!!! This is a much better modem by far! Not a problem with this modem. My Arris crapped out at week 2.

Better than netgear. I bought both this and that and return the other. Love this Motorola, no interruption of service. All my webpages open fast.

This modem took care of the disconnect problem I was having. The speed and through put is exceptional.

The product had a very high rating among the technical community which was the basis for my purchase decision. The fact that it was available from a reliable business like Walmart at a competitive price and free two-day shipping made my choice of vendors very easy. It arrived on time and is already in service.

So far so good. Was a reasonably easy setup on Xfinity (took a couple tries). Has been pretty stable with reasonable speeds. I didn't need the 1Gig speed, but comcast EOL'd my old DOCSIS 3.0 modem..... Hope things stay good - no way to know, but my experience thusfar has been good.

Our Internet provider (a local cable company) sent us multiple messages that reported both the good news that our service would be moved to its 400+MB/sec level at no extra monthly charge and the reality news that in order to experience the full benefit of that new speed, we'd need a modem that meets the DOCSIS 3.1 standards, which our then-current modem did not do. Since we own rather than rent our modem, I decided to investigate the benefits of replacing our perfectly good DOCSIS 3.0 modem. I ran a speed test on our old unit and achieved a speed of ~250MB/sec - very, very good, but not 400+MB/sec. So I ordered this Motorola unit from samsclub.com, in part because I trust Sam's Club, but more because the Motorola device was on our provider's list of modems it had certified to work with their system. Since its installation in our home, the unit has returned speed test results consistently in the mid-400'sMB/sec, and that's while connected via our router. BOTTOM LINE: This Motorola modem works, works well, and works as advertised. I recommend it unconditionally.

Still early but working great. You may need to call your internet service provider (ISP) to initially activate after you have it connected and turned on. First and foremost, make sure this/any modem is compatible with your ISP before you purchase. Call them or check their website.

The Modem is really tall. I'd prefer a smaller modem. At the time of writing this review, I have only had the modem for about a week now. You have to call your Cable provider and give them the Mac Address (number) from the label on the bottom of the modem before it will work with your cable service. After I did that, the modem had no trouble connecting to the internet. It's pretty much plug and play. The cable representative told me that he thought it was overkill. He likened it to buying a Ferrari and only driving it 55 MPH because I only have a 100 mbps down stream plan. He said that their company (Wave Cable) dropped this particular modem from their list of approved high speed modems because of many of their customers experiencing frequent random disconnects using this modem. So far, I haven't experienced that, but as I said, I've only had it for one week, now. Time will tell. I'm considering upgrading to the 1 gig down stream plan to find out if this Ferrari will really do 1 gig.

The technician who installed the internet connection at my house did not take long to install and activate this modem. So far, I have had no outages or service problems due to the router (I live by myself. No roommates, or so). Take care, though: This is a modem only! It connects your home to the internet, but it does not provide Wi Fi signal. You have to take care of that by yourself, either by purchasing a normal Wi Fi router, or a set of mesh routers (the latter is definitely your go-to option if your home is larger than 1200 - 1500 sq. ft.). If you are not familiar with all these technicalities, definitely talk to someone who is.

I bought one of those modems from Walmart, it is very slow on download and upload. I'm trying to return it I have been given the runaround the seller keeps telling me to take it to Walmart to get a refund and Walmart is telling me it's not their problem you have to deal with the seller directly, this is a nightmare that Walmart must put a stop to since I bought it from their website
