Needed to replace my modem with comcast because i went up to a higher tear. This modem is very good and no issues so far.

So far so good! Replaced an Arris with this Motorola and it is working alot better with less problems then the Arris- I will never buy another Arris- they are only good for maybe a year, 2 max!

In the past 2-3 years. I had been getting Netgear Modems and they tend to go downhill really fast and slow down a lot. I've had this Motorola Cable Modem for a few months now and it's the best modem I've ever had and the speed is amazing and has not slowed down even a little bit.

Replaced my Cox Panoramic modem with this one. Didn't miss a lick and in the long run, it'll save me money.

Easy install and setup with my ISP. It didn’t resolve the network issues that I was having, but that wound up being an issue that my ISP had to resolve in my entire neighbor hood. I kept it since it was an upgrade to what I had previously.

Got this so i can stop renting the xfi gateway... Hasn't paid itself off JUST yet but almost and I love it

Pretty pricey but overall did speed up my internet from my previous surfboard modem

Very easy to set up. Good value for the price. Much faster than my previous modem.

Has special features to reduce buffer bloat that is now more common than ever. Playing FPS games? You need this!

by far the best modem i have ever owned, worth a buy, highly recommended for comcast 600 mbps plan. i pay for 600 and i get over 900 mbps down, 25 up. with my ping at 10 or 11 with this modem! 500 thru wifi down and 23 up when used in combination with an orbi 3000

Motorolla MB8600 Docsis 3.1 Purchased this then increased my internet speed with concast/xfinity to 300. Test speed on my google router shows 317 to 323 speeds' perfect for my needs. Nothing to dislike about the product or use.

I replaced an old modem “2011” purchase a quick call to comcast and I was all set

What can I say, I had it for a couple of weeks and it works. Lets see how it's doing five years form now.

I’ve had this unit in my home for a year now, so when we upgraded our internet at our small business. There really wasn’t anything else I could think to purchase. Modem is absolutely rock Solid. Has not gone down once, just like the other one we have at home.

bought this to replace the cox unit we'd been paying monthly for. seems every bit as good as that, but it wasn't enough to handle our transition to streaming tv all by itself. ended up buying a 3 pack google mesh unit to help carry signal throughout the house and now all the tv's operate seamlessly.

Quick easy install. I really didn't notice a speed improvement over the previous modem that I had.

Stop giving cable companies your money by renting your modem. I bought this one and have no problems

Great and strong router, loving this router best router I've ever owned. Would recommend to family and friends

I purchased this to replace an Xfinity all-in-one gateway. So far it has been more stable.

This is a good replacement for the rented modem that was used previously. Works well with Comcast.
