Made My internet Slower
After installing this modem I instantly noticed how web pages would load much slower and my gaming pings were inconsistent. I did buy a refurbished one so maybe that was the issue. though my speed tests would come back with a maxed out download speed (i have 300mbs and the speed tests would show between 275

Problem Solved
I upgraded my Netgear CM 1000 because of buffering. The new modem has improved this problem.

Best modem so far
My old Nighth hawk Modem stop working and had to get a new one. This 2.5 g appears to be faster. I connected to my Night Hawk rotter with Cat8 cable. Cat8 transfer data faster for 2.5g modem. So far product works good. Although you need to have equipment that accept 2.5g in order to utilize full function of modem.

Great modem
I had the cm500 and after 6 years of use it was time for an upgrade. This unit has been outstanding and worth every penny.

Dead after 4 months
First, it took close to an hour jumping through hoops and working with xfinity to get working. After 4 months, it just died. Do not recommend.

Great product
This cable modem is amazing! However, it wasn't what I needed so I had to return it. I needed one that will connect to a switch and then connect to 4 other devices with a wired connection.

Solid choice
Needed to upgrade my 4 year old home cable modem so replaced my CM1150DV with this one - didnt need the VoIP support any more. Set up was a breeze, was up and running in less than 20 mins - 1 week later and have had zero issues.

Top Modern Modem
I did a considerable amount of research prior to purchasing a modem to service our newly built home and brand new television. I chose the Nighthawk because of the high specifications and highly rated reviews. Once installed – by the way, simple, straightforward install – I checked the speeds and the speeds were a tad higher than the stated speed provided by my Internet ...

Awesome modem!
Needed a new modem to accommodate increased internet speed. Swapped out the Netgear CM700 for the CM2000. A quick call to the ISP and we were up and running in no time. Download speeds have improved greatly. Pairs perfectly with the Netgear R7000P router!

Replacement of Xfinity Modem/Router
[This review was collected as part of a promotion.] We are attempting to reduce our overall expenses and the Xfinity equipment rental fees was one way so we purchased a cable modem and wireless router from NetGear. It was an easy install because of good instructions and all is functioning as advertised and expected. We're very pleased. Thanks.

Netgear CM2000 upgrade from CM1000
Replaced an older Netgear CM1000 modem when I upgraded my Xfinity service to 1Gbps. Simple, straightforward installation and reconfiguration. It's fast and hit 750Mbps right out of the box, increasing to 950Mbps in use.
Quality gear that performs exactly as advertised.
