Customer Ratings & Reviews

Got tired of paying ‘rent’ for the Xfinity Comcast piece. Pays for itself within several months. Noticeably faster too.

The CM 600 provides a good signal and connection to my ISP. Unfortunately it does not provide an Internet connection to my Netgear R6300-AC1750 WiFi Router. Apparently it will not assign an IP address to the router when using the router as a DHCP server for my home network. This looks to be a firmware issue with either the router or modem. If you choose this modem and are using a R6300-AC1750 or another Netgear router - be sure QoS is switched off in your outer configuration since this is what I was informed was the source of the issue. The Average rating and No recommendation are due to my issues with the CM600 not interfacing with another Netgear product.

Not much to add...it does its job! I get the speed I need at home for video upload and download and online gaming.

Replaced a rental modem. Brand recommended by cable company, model recommended by Best Buy personnel. Works well for us. Was easy to set up.

Upgraded my old Modem and read great reviews about this unit. The reviews did not lead me wrong. I am enjoying fast internet once again.

This is great modem don't have to worry about my cable company upping their speeds for a few years this modem can handle even the fastest speeds

I've been using it for 1 month with Xfinity 75MB. No problems so far. It works extremely fast and works great with an Asus RT-N66U router.

Netgear delivers again. Plug and play, easy peasy. Hook up all your cables, call your ISP provider and rock n roll. It's foolproof!

This is a great product, easy to set up and geat step by step instructions.

Product works as expected and is easy to use. Each cup is easy to measure, only default is you can't overfill for larger cups of coffee

I know it’s not docsys 3.1 so eventually I will need to upgrade. I didn’t see the need to spend the extra money at the moment. After upgrading, I am seeing 100+ mbps from my ISP. Prior I was getting 30ish.

I bought this modem to replace the internet provider supplied modem. This modem is performing much better and faster than the old one.

I bought this to replace a Comcast modem because of slow speeds. Easy installation and immediately saw an increase of 50 mbps in speed.

Replaced my motorola docsys 3.0 with this, and no more connection issues. Run all my devices and hookup was extremely easy with my provider.

Wow. I was in dire need of a new modem and this one was exactly what I needed. Now all I need is a good router and my house is set.

I’m really recommend to anyone, Who is having a lot of trouble with their Cable and Internet. Work awesomeness.

I needed a replacement modem that supported higher connection speeds and this one fit the bill nicely. Fast, easy setup!

Works as expected. Needed to contact tech support at cable company to have them make adjustments on their side to get maximum performance.

Does what I bought it for to deliver speed to my household. Nice design, value priced and meets expectations!

I was having problems with my Surfboard modem and decided to try a Netgear instead. After 1 month of use, it's still rock solid.
