Being low in funds, we endured the daily thrice resets for three years. What made it worth it was the day I could take a hammer to it and send it away in the garbage.

It has a very fast connection to the internet but the only thing it only has one Ethernet cable port. Other than that it's hands down good I play online gaming and I use it always.

For about $50, this modem improved my speed on Comcast to a bit above what I'm paying for. Better yet, you can often find this model on sale.

I always wanted to end the ridiculous "cable modem rental fee" and found this product via a tech blog. The Cable Company Tech Guy needed to install it, but it has been working well ever since. It definitely seems to be a better product (performance and reliability than the Cable Company modem. And, we never have to pay the modem rental fee again. The ROI on this modem is less than 6 months.

I bought this Netgear CM400 modem to replace the slow one provided by my internet service company. Once I installed this modem in conjunction with the nighthawk router it dramatically improved my internet download/upload speed and range. Very pleased with my purchase and will buy netgear again in the future.

I bought this to replace my Comcast dual-band router. I was pleasantly surprised at how easy it was to set up and also how fast my connections are. It didn't take any configuration to get this up and running in less than 10 minutes. I had to get a router to connect to my other wireless devices, but this modem was what I needed to handle the 150 Mbps performance from my network provider. I would highly recommend this modem!

This modern modem is pretty easy and adjustable for your internet- wifi connection. Especially for Xfinity but it works fine with other carriers too .

This is not only a reliable modem but a money saver in two ways. It was affordable and it eliminated the rental fee from our cable provider.

A neighbor was stealing our internet and my children were being bumped off while they were working. Since I've had the new Net Gear modem and router. We have had no problems. But my neighbor has.......

My last modem had to be reset every couple of days. The CM400 is a rock-solid, reliable workhorse that I would buy again in a minute.

After years of paying monthly "rental fee" to cable company for modem use, decided to buy my own. Not being very "techie", I was hoping I had made the right decision. Couldn't be more pleased!!

From day one of having this modem it has been flawless. Other modems we've tried always had connection issues. But not this one. It is consistently reliable and at full speed all the time

I bought the modem because it was compatible with the requirements for Spectrum so I didn't have to a monthly rental fee. It works great in the background without any issues.

Although I've seen some reviews that say after 5 months or so the modem begins to drop connections. So far, I've had no problem and anticipate that I will continue to enjoy a well working modem. Thanks Netgear!
