Rated 5 out of 5 by from Great router! Super fast!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!

Rated 5 out of 5 by from Awesome Modem!!!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.

Rated 5 out of 5 by from Good for your moneyIt 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.

Rated 5 out of 5 by from Couldn't be more pleasedAfter 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!!

Rated 5 out of 5 by from FlawlessMy 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.

Rated 5 out of 5 by from Works Great!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!
