Customers are saying

Customers are positive about the product's impressive speed, strong performance, and overall ease of use, including its simple setup and seamless connection. They also appreciate its compatibility, DOCSIS 3.1 support, and affordable price, noting that it operates without lag and stays cool. However, customers are negative about the limited number of ethernet ports and, for some, the signal strength.

    buy what you need, check against what you're replacing or if you are in need of an upgrade. This modem fits my need and is compatible with my internet service provider. I probably wont have to upgrade this device for a while. Check with your internet provider, check your speed and look at how you use the internet , school, business, streaming, gaming. Then buy.

    Works exactly as it should. I've had it for a year now and have had no issues. I have 900mbps speeds through my ISP. This does now have a router so pair it with a gig speed router and you'll get high speeds.

    If you have GB internet this is the modem you need. I upgraded my previous Netgear modem to this one when I went to GB internet and have full speed now. I have it kind of hidden away but it looks good enough if I ever needed to move it out in full view.

    Excellent DOCSIS 3.1 gigabit modem

    The NETGEAR 32x8 DOCSIS 3.1 Modem is ideal for anyone looking to upgrade to gigabit Internet, especially for those customers of ISPs that mandate DOCSIS 3.1 modems for gigabit plans. Easy set-up and more cost effective than renting cable modems from the ISP.

    I bought this modem to replace the one that was supplied by my cable provider. Their unit was not working satisfactory and I was paying about 18$ a month for it. This modem works well with my fast 1gigabit connection.

    I replaced my rented cable modem from Cox in San Diego with this unit and so far so good. The Cox website does not list this modem as supported but it has worked well so far (you need to use customer service to get the device on their network) and I like the ability to upgrade to Gigablast at some point. I will update down the road.

    Great purchase and was recommended by a Best Buy employee. We purchased the router to avoid high monthly rental costs with our internet provider. They installed and it’s worked perfectly since January.

    Has performed very well since purchase. Recommend this model over the Motorola versions for cable internet. This particular model doesn't support IP phone service, so make you don't need it.

    I bought this to replace the cheap Technicolor modem supplied by Mediacom. The Netgear is far superior and even with just 16 channel bonding, we're getting speeds in excess of 900Mb. Easy to use, easy to manage. Great modem!

    Updated my modem to this version and am now able to enjoy faster internet. Appears my prior modem wasn’t able to handle the speed I had purchased. Paired this with Orbi mesh network router and I’m really pleased with the results.

    Got gigablast from cox along with the router/modem they give you. It worked ok enough for web surfing but I still didn't see a change when online gaming. With the help of a Best Buy Associate I chose this modem with the google mesh routers and now everything is truly blazing fast.

    Excellent cable modem. My only disappointment was that it does not have a wireless router on it, but that was my fault for not reading the box before buying it. The modem itself is excellent and has been working like a champ.

    One of the three fastest routers supported by my ISP. In-box documentation was chintzy (how about something to tell me what the indicator lights are?), but once I got through to a live tech-support person at the cable company, everything went fine, and it works well with my NetGear router.

    I do not use a wifi router at home, so I needed something with a ton of power. I use enterprise level equipment so I got the best I could find without spending a buttload. would recommend, it delivers every ounce of internet your ISP can dish out.

    After having The Arris Surfboard SB6141, I was in need of an upgrade. This product is great, and had gave me no issues. Netgear also has great customer service. So when it comes to this modem I say grab this one and don't hesitate to invest. FYI this does supports the 1gig service.

    I have 600 mbps internet speed through my provider and runs it flawlessly. My previous modem with the same router was intermittent part of the day. So far there has been no issues and works as advertised. An added note is it runs fairly cool.
