Customer Ratings & Reviews

Very compact and good performance. it is very good alternative to the cable company modem.

The modem was as described. It was very easy to set up and I was connected in minutes. Just plug and go pretty much.

I bought my own modem because I didnt want to pay a monthly fee to rent from Time Warner. This does everything it's supposed to do. Setup was simple, hook it up with your wireless router, make sure your service is activated and there ya go! I stream movies, tv shows, download music, speed works great for me.

Great value and a good entry level model for service < 100 Mbs. Works great for a 5-8 device network.

This item will save me on Cable fees and was well worth the investment. Easy to install even for an OLD guy like me.

Great modem for the money. I’m using it with Comcast Xfinity internet and my speeds are blazing fast.

The NETGEAR CM400 High Speed Cable Modem provides a connection to high-speed cable Internet, up to 340 Mbps. With DOCSIS 3.0 it is 8X faster than 2.0. It is CableLabs DOCSIS 3.0 Certified to work with cable Internet providers XFINITY from Comcast, Spectrum, Cox, Cablevision and more

I work from home and we have 2 computers, 1 tablet and 4 phones connected to our wifi as well. Keeps up with all of us.

Great modem purchased to replace modem from cable company which I paid for monthly....saving me money and works great!

Bought the more expensive one but took it back because my ISP said I would have to upgrade to use that modem. Traded it in for this and get over 150 Meg download when I'm only supposedly paying for 100. No complaints with this modem. Works great and perfect size.

I was not looking to spend a lot on a new modem, and this modem did the trick!

I found the installation straight forward and the setup quick. This product is reasonably priced compared to others.

I purchased this modem to upgrade my old Motorola surfboard modem and my download speed used to be 23 mbps, but now its 50+ mbps! This is a great modem at a great price and was recommended to me by a TWC technician over the Arris/Motorola modem. The only problem I have is the connection goes in and out sometimes.

We managed to "survive" with 6 GB/S for several months but since working at home and doing online streaming, it was not cutting it. We got the 50 GB /S from TWC and did not want to do the modem lease. This device is very affordable, easy to set up and provides us the speed that our house needs.

Great product never had any issues after being installed. Great value.

The modem was purchased to replace an older model on our comcast account. It was an easy experience to setup, as easy as comcast makes it. Other than them taking a few minutes longer than needed. It was setup and running in less than 20 min. I have Luma mesh networking hooked up and it is blazing fast.

The modem is compatible with Time Warner Cable company and with using a linksys router for a small area of signails

Bought it for my Time warner connection. works fine with the service!

Ever since I got this, my internet has been great and not kicking out at all like it used to with my old modem.

This combined with my router gives me the speed that I’ve actually been paying for from TWC.
