Very easy to set up. I removed my old modem and plugged in the power, the ethernet cable, & the cable line. I opened the Xfinity app on my phone (you need to have a phone to set this up - need to use data and not wifi) and click" activate now" under "Got new equipment to set up?" The app prompted me to enter the MAC ID number which is on the box and also on the modem. It took around 5-10 mins for Xfinity to recognize my device. We have a web of set up with router, control 4, security camera, etc. I didn't have to configure anything.

Router was extremely easy to for this neophyte. It looks cheap but works great.

After upgrading to a 200 MBPS service, my original modem was not compatible with this upgrade. The ARRIS SURFboard 32x8 DOCSIS 3.1 can handle our three TVs streaming internet broadcasts, plus computers and tablets without annoying buffering and dropouts.

I purchased this modem to replace the modem/router combo I was renting my my service provider. This was easy to connect and setup with my ISP. I have had no issues with it yet, and it was also easy to connect to my router. Highly recommend.

I finally can get the maximum speed Comcast offers since it has the full DOCSIS 3.1 spec. It's crazy seeing a Steam game downloading at 70 MB/s... and this is through an ASUS router too via Ethernet

This modem is fast. I have Xfinity internet and have used their monthly all in one rental modem/router. I used it in combination with an Eero mesh router system. I know you shouldn't but it gave me "free" unlimited data caps when I rental their modem. Even though their app shows I'm getting advertised speeds of over 1000 Mb when connected directly to their modem, I get less than ideal when on the Eero mesh wifi or the ethernet port. I know that my Eero maxes out at 350 over wifi but I was never able to obtain those speeds even on ethernet backhaul. After swapping Xfinity modem for this one, I can say that my problem is resolved. Speeds are saturated and I get gig speeds when I'm connected directly to one of the Eero routers' ethernet ports and over 300 Mb on wifi.

Purchased this in combination with a Linksys Velop series mesh router system. Leaps and bounds better. Automatically configured and set itself up when connected. Nice that I didn’t have to speak to a Cox representative. Worth it.

Have a previous Arris SB6190 that lasted for over 10 years running 24 hours a day. Had to upgrade to a Docsis 3.0 modem because my internet service would overload the 6190 and it would just freeze for 2-3 seconds every hour. This model is basically the same thing but more channels to handle faster internet up/down loads. I hope it lasts another 10 years+!

Easy to connect, gave Cox the info to update to this modem and all went smoothly, no complaints after a year

Currently using this with Xfinity and getting 1000mbps when hard wired to the back with PC. To set up the modem, I needed to call Xfinity and get them the MAC address off the back. This is outperforming the one they provided hands down.

This the second one, love the speed,easy setup,plus don't have to buy from internet provider.

I was looking to replace my old modem to upgrade the speed for my PS5. It made a big difference in speed and reliability.

Great new router. This replace my last router which long overdue. It was simple to connect to my provider. I was up and running in about 5 minutes. Made simple and easy.

Easy set up. Works amazingly well. Looks clean and sleek.

Very easy to setup & install. Upgrading allowed us to take advantage of the higher mbps our internet provider was offering.

Easy to set up and works great! Great price for a quality item.

Easy to setup. Reliable. Added speed to our setup. Works seamlessly without mesh system.

I got a good price on this and it was easy to set up after I contacted my internet provider to register it. I get much more speed from my internet now. I bought this on a recommendation from the IT guy at work.

Great board, mediacom compatible. Cheapest Docsis 3.1 on the market. Great if you are on a budget.

This is a speedy Modem! I replaced comcasts version with this unit and saw immediate speed increases. Additionally, there were no crashes to date!!! In the previous comcast unit, I would have to reset at least once a week. This unit is trouble free and fast!!!!!
