This is what you need to access updated Xfinity internet speeds. I needed a modem that was approved for the 200 Mbps upload. I learned the hard way that even though a modem is capable, Xfinity has to approve it and they keep the list short. Whether this a way to force you to rent one of theirs…you decide. My current modem was a CM1100 that Xfinity no longer supported. I needed a modem that allowed link aggregation because the Orbi mesh router I have only has 1Gbps internet port and Ethernet so to access the 1.2Gbps I am paying for, I needed a second link. Surprised to find most modems do not have this. Keep in mind it has a 2.5Gbps internet port for those that have routers with the same. With the CM1100 and link aggregate I was getting 1250Mbps down and 40Mbps up. With the CM3000 and a single Ethernet, I am getting 900Mbps down and 220Mbps up. With link aggregate (two Ethernet setup) I am getting 1450Mbps down and 240 up. I took about 20 minutes to get it set up. I unplugged the old one and plugged in the new one to coax and power. After two rounds of letting the lights fully boot to solid, I used the Xfinity app to manually add the MAC address. There was a link below the internet modem status to add new equipment. I finally plugged in the Ethernet and powered up the router.

Incredible product. Rock solid. Easy to setup with the cable company. Getting 2200mbps down and 300 mbps up on Comcast Xfinity 2gig in SF on mid split!

Excellent modem, super fast, instant jump in connection dpeed. Runs quiet and cold. Great workhorse… literally no setup required, just plug and play…

I’ve tried multiple modem/router combos over the years, and most of them promise high speeds but choke under real-world load. This one is different. I’m on Xfinity 2 Gbps plan, have a house full of smart devices, cameras, TVs, and heavy gaming/streaming happening at the same time – and the connection stays solid. No drops, no buffer, no overheating, and the upload speeds are noticeably faster than what I used to get with my older Netgear C7000v2. Setup was painless – literally plug in, activate through Xfinity, and done. It handles WiFi 6 perfectly, and I finally see consistent speeds on all floors of my house without needing mesh extenders. Zero hiccups during Zoom calls or Xbox online gaming. Price isn’t cheap, but if you’re tired of replacing weak equipment or paying rental fees for mediocre ISP devices, this is 100% worth it. It does what it claims – stable, fast, and reliable. Highly recommend.

The Netgear night hawk works great and is fast!! Looks good and hidden out of the way

I recently upgraded to Xfinity’s gigabyte X2 internet package, which gives you 2000 mbps on download and up to 200 mbps on upload. To take advantage of the high speeds, I decided to upgrade both my modem and router. I purchased the TP-Link BE800 router and the Arris Surfboard S33. When I hooked everything up, my download speeds were capped around 1200 mbps and upload speed around 41 mbps. After reading multiple reviews online through Xfinity’s community forum, and other reviews, basically I found out I needed to upgrade to a modem to get the higher upload speed, so I purchased the Netgear CM3000, since the Arris S34 isn’t available yet. After hooking up the Netgear modem, my upload speed was still capped at 41 mbps, so I chatted with Xfinity technical support. During the chat, the Xfinity tech updated my firmware on my modem, and my download speed increased to 1500 mbps and my upload speed increased from 41 mbps to around 360 mbps! Basically, not only do you need this modem to get the high upload speed, you also need to have Xfinity update your modem on their end. All in all, it was definitely worth the extra time and money since i now can take full advantage of my high Internet speeds!

Works great and was easy to set up and connect. Our Internet has been noticeably faster.

Ordered online and picked up in the store. Very easy to setup. I just called my internet provider, told them the MAC number and then hook it to the router, done! Strong signal. I have 1G plan, and got 540 download and 57 upload speed.

Great overall experience!!! Easy setup with our eero WiFi router. Excellent choice!!

The Netgear Cable Modem has consistent, reliable connectivity. The features and value make it a good Cable Modem.

Such a great modem. Fast and reliable. Must buy…..

I bought this modem for faster speeds since I have the 1 GIG internet with Spectrum and it definitely did not disappoint. Would buy again and recommend to others.

I upgraded my modem due to only getting 900mbps out of the 1.2gbps I was paying for through xfinity. This modem nearly doubled my speed and I am now getting the full speed I pay for plus some. Well worth it if you have the 1.2Gbps plan with xfinity.

One of the best modems I’ve had got rid of my old internet providers equipment due to laggy connection and not getting the full gig , this nighthawk exceeds the gig I pay for from time to time I truly get the connection I’m paying for it fixed the lag and never drops connection 10/10 for me !

Overall, it has been a nightmare to try and get hooked up and going. It doesn't like to cooperate through the app and there are many others like it close to the same model/serial #. Your provider might just look up the item and log the wrong product into your account. Honestly, you'd be better off just getting a modem/router combo.

Bought on the recommendation of a repairman when my old equipment was having issues with evening reliability and upload latency. I learned that Mediacom is moving completely away from the older 3.0 cable service, and their updated list of compatible modems is awfully thin. So, I took a chance and bought this CM3000. While the price is steep, the quality and ease of use can't be denied. Set up was very easy both out of the box and with a phone call to Mediacom, and it's certainly the nicest modem I've ever owned. It's also a fair bit larger than my old one, and I'll need to find a new spot to keep them. Time will tell if the hefty investment is actually as 'future proof' as advertised, but right now, I'm very satisfied. It's been extremely reliable, returned my latency to what it should be, and boosted my speeds across the board.

This modem is definitely helping me utilize all 1gb of my internet when you pair it with a halfway decent router. Highly recommended. Easy set up. Looks sleek too.

Absolutely love this modem. The NETGEAR Nighthawk DOCSIS 3.1 has been a game-changer for my home network. Speeds are blazing fast, connection is rock-solid, and setup was a breeze. It's one of those rare tech purchases that just works—and makes everything else better. Worth every penny.
