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.

    My fault for not buying the protection plan because i usually do but i thought with netgear the quality would be a little higher. When fully functional, this modem is awesome. Super fast internet and we love it. But it took a little tumble and now doesnt function at all. Cant recommend.

    No, I would not recommend this to a friend

    Bought this modem so I wouldn't have to pay Comcast's wonderful rental fee. Thought I'd go ahead and buy something to future proof myself a bit, so I grabbed the CM1000 since it's the only DOCSIS 3.1 modem available. Turns out the firmware on at least some of these has a critical flaw causing it to randomly disconnect. From reading online Netgear has fixed the issue, but there is no way to update the firmware yourself. Seems to me that either Netgear has decided not to recall the bad modems, or I got a box with the new firmware and it's still not fixed. Either way I'm heading to return this and get an Arris modem or something. Left it at 2 stars because while it works it's great, Having to restart it a couple times a day to get my connection back is not terribly fun.
