    Due to now working at home fulltime, I had to upgrade my bandwidth for my Xfinity circuit. Along with the circuit upgrade I had to upgrade my modem. Originally I leased a modem from Xfinity and it had issues with consistent speed and connectivity, so I decided to try the NETGEAR - 32 x 8 DOCSIS 3.1 Cable Modem along with my my Google nest mesh for Wifi. Its been over a week now and been solid, not reboots, speed or connectivity funkiness that was happening with the Xfinity modem.

    This is the modem for those who want to just "set it and forget it". I bought this one because I don't want a bunch of bells and whistles — I want a simple modem with a minimum number of connectors that is easy to set up and is powerful and reliable. So far I am pleased with this choice. There has been one power outage since I installed this modem. My internet was back up and running within minutes after the power came back. With this modem being more advanced than the 6 year old modem I replaced, I have seen an increase in data speed, which is good because I am very demanding of my internet connection. It seems a bit expensive for such a simple modem, but the simplicity and reliability is worth it to me.

    This is a great next gen modem. This actually makes your exisitng wifi faster. I have xfinity modem. When I swithced to this modem my speed went from around 170mbps to about 220 mbps just like that. Pair it with a netgear router it becomes even better. Its great small in size and easy store. Perfect next gen product with docsis 3.1

    This modem has worked great for me. I have spectrum's 400mb plan. With my previous hardware I was barely getting 100mb in, I'm now getting close to my full download speeds consistently. I haven't any issues with the hardware needing to be rest or having to made multiple calls to spectrum for speed issues like with my previous hardware.

    Could be better

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    After 3 years, it's okay... The first two years, the modem worked without a hiccup. This past year though, I've had to power cycle it at least once per month with the occasional "reset" button. Which after looking at Netgear forums, this is a known issue. If it wasn't a pricer model, I'd have more forgiveness.

    Our cable internet provider upgraded our service to super-fast, but didn't even have any modems available that would handle those speeds and we would spend half of our internet time reconnecting to the home network. With this modem and a good router (TP-Link) our home network easily handles everything we through at it and no more getting kicked off at the most inconvenient times!

    Best Purchase to be Free of Xfinity Rental Fees

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    When I finally decided to give up my Xfinity Voice and no longer needed to rent their proprietary voice gateway with subpar wifi, I started to do research for top-of-the-line cable modems and top-of-the-line wifi routers. The CM1000 is DOCSIS 3.1-certified, is supported by Xfinity, and will support up to gigabit ethernet. Setting it up with Xfinity was pretty painless. Haven't had a problem with it ever since I bought it. And now that I no longer have to pay that damned equipment rental fee, it will pay for itself over time. Must buy if you're an Xfinity customer! Caveat Emptor: If you have Xfinity Voice, the CM1000 WILL NOT support your voice service. Additionally, realize that the CM1000 is purely a cable modem and has no integrated wireless router.

    I haven't had a single solitary issue with this modem since I purchased it...and I think I may have rebooted 3 times in the past 6 months. It is definitely a 'set it and forget it' network accessory. I get about half a gigabit down and 20 up into my place and this sustains my connection speed like a champ!

    Many ISPs haven't gone up to Docsis 3.1 but this is backwards compatible making it future. This modem has 32 downstream and 8 upstream channels which is far above from what ive seen so far currently RCN requires 24 channels down and 8 upstream where as xfinity has yet to make the jump in most areas. This however is xfinity approved so you know its coming. There was a small issue upon installation but not to worry those are expected regardless of brand although i was surprised to find out netgear was little to no help regardless of the 90 day support printed on the box. If you have an issue as i did where it causes you to reboot the modem every 12 to 24 hours i would suggest calling your ISP and asking them to provision your modem after you perform a factory reset, this can clear a corrupt config file. The bottom of the modem has a http address with helpful features.

    This is the best purchase for modem, I currently had (ARRIS SURFboard SB6121 4x4 DOCSIS 3.0 Cable Modem pair with router NightHawk X10) and start failing me with speed dropping completely to 0MB/s at times. Tested by connecting it directly modem to desktop and was getting same speed dropping. I have Blast (250MB/s DL & 10MB UL/s) speed from Xfinity Comcast, with the old modem didn't see speed higher than 135MB/s DL. That wasn't bad until it started to failed, then I realized that it has not been my IP fault I wasn't getting the full 250MB/s, it was me with an older modem with top DL of 175MB/s capable. I started to research to see what modem to buy and since I already have the router Netgear NightHawk X10 and no problem, I look into netgear modem and read the awesome review this one has, so I decided to go for it. Installed it and the first speed test I did it blew my mind with speed of almost 300MB/s DL!!!! Now it is a steady 250MB/s DL speed (+/- 30MB/s) I turn every device and streamed HD videos some ULTRA HD and not one ever buffered.

    I had signed up for 500 Mbps from my provider, but was only getting 140 Mbps. Then came to know I had to upgrade to DOCSIS 3.1, I found this on Blackfriday sale and could not pass the offer. I am one Happy user, now I am getting a little over 650MBps with this new Modem

    I had the same model prior to purchasing this unit. My last one went out on me so I got the same one again. By far the best modem I have had. Saves me from renting one AND I get FASTER speeds then rented ones. Super easy to set up and running with in 5min of taking it out of the box. Definitely recommend this modem if you are in the market!

    The best Modem for Fiber!

    We have Comcast Fiber and this thing works like a beast! I get 930 Down and 43 Up. I also have an Asus 270H mobo. My roommate currently gets 43 up and only 240 down, we think this may be because his mobo is a 170 and although the LAN's driver is up to date, it may not be able to keep up with that speed. VERY VERY easy to set up. Just follow the instructions.

    Recently, I had moved and was forced to give up fiber speeds of 1000mbps up and down. The only provider is Comcast in my area, so I was forced into purchasing this and their 1000mbps plan. It works well after some adjustments, however upload speeds are not that great. Think that's my ISP however. Matched it with a nighthawk x10 and works smoothly throughout my house.

    We wanted to replace our modem router with a better unit then the one we have. This unit seems to be the right one for the right price was easy to install and it’s working really nice with all the different Wi-Fi units we have in the house. Purchased online with the easy pick up at our local store.

    Replacing my older Netgear modem that was getting overwhelmed by the Xfinity internet speed increases plus it would lose connection too much. This one is much more stable and able to handle the higher speeds.
