Easy to install. Just plug it in and go. We are realizing the full 1 GBps from our Comcast Xfinity internet service. Flawless!

Needed a newer modem to upgrade to the higher tier internet speeds. Has worked great so far, easy to set up with provider.

Works just like advertised. Very easy to hook up. Extremely fast Internet speed.

Simple and functional. This cable modem works with Comcast for Gigabit Ethernet via DOCSIS 3.1 and will save you paying their equipment rental fees.

So far I have not had any issues with this modem. It was easy to switch out without any troubleshooting. My fast internet works well with this item.

Works great with my Comcast provider. Provides me with the speed and performance for my internet account.

This device gets me almost 600mbps with RCN. I am paying for 500mbps and it works great. No wireless but that's no problem because I got the Google wireless routers. The only problem that I have with it is that it gets super hot!

Worked perfectly right out of the box, easy to instal. The increased speed was very noticeable.

Purchased for second home so cable company can't RIP me off my charging a monthly fee for their modem FOREVER. This system has been stable, reliable and fast.

Purchased as system update to increase speed from prior cable modem. Easy set up and use, much better than paying a monthly rental fee to Xfinity for their equipment .

Excellent, very reliable, watching my streaming services as I type.

a must buy for great internet speed, better then the one provided by your cable companies

Definitely better than our old zoom modem. Connected this with a Netgear mesh wifi system and couldn't be happier with the speed and connection.

I got this and sent the ISP back their requirement. It has more than paid for itself. It’s easy to use and has the speeds as advertised.

Wow! This Newest version of the surfboard from Arris is fantastic..!!! Now I’ll be able to handle my ISP’s top tier speeds.

Overall a good modern. However there are a few things that could be better: 1. There are dual 1G ethernet port on the modem. It didn't say clearly if they can be connected to different wifi router (which they can't). The only use is for bonding to form a 2Gbps link to a router that has two WAN port that support bonding, which is rare. So this design isn't that useful IMO. 2. Even with 2Gbps link, it's nowhere near the 10Gbps max rate with DOCSIS 3.1. That's being said though I don't see xfinity giving 10G options in the near future. So it's ok.

This is a very stable, fast modem. I haven't had any need to hard boot the device yet and it has resolved an issue I was having with my Internet previously. I had an Arris 6142 and it couldn't handle large upload spikes. I have several Nest and Arlo cameras and between their uploads and bursts of uploads on my PCs or other devices in the house, the modem would use all the bandwidth and start dropping large amounts of packets. When this would occur, sometimes the modem would lock up entirely and need a hard boot. This is an expensive modem but I know it will serve my needs for several years given its bandwidth capabilities.

Works great. I'm really happy with my purchase. The speed is great I never lose internet service works great.

Easy set up. Works beautifully. Very helpful service at the store. Friendly and knowledgeable staff.

Excellent modem with DOCSIS 3.1 and supports my 400 Mbps internet service! Easy to set up. Up and running within about 20 minutes.
