Netgear CM600-100NAS (24×8) DOCSIS 3.0 Cable Modem. Max Download speeds of 960Mbps. Certified for XFINITY by Comcast, Time Warner Cable, Cox, Charter & More (CM600)

Recently Released Netgear CM600 Cable Modem – Best of the Cable Modems Right Now
This new DOCSIS 3.0 modem by Netgear was just recently released. It has 24 downstream and 8 upstream channels for up to 960 Mbps of download speed, and a little over 200 Mbps of upload speed. I had just purchased an Arris SB6183 about 2 weeks earlier to upgrade my older Motorola SB6120 modem (Arris has since bought out the very reputable and reliable Motorola modem division). I had to do this to maximize my Blast internet speeds since receiving a free speed upgrade from Comcast.The Arris SB6183 is a very popular modem and probably the one most people buy. However, in my case, the Arris SB6183 kept randomly dropping my internet connection and rebooting. The connection would resume after each reboot in about a minute or two. When I contacted Arris about this I was told that Comcast’s upload signal was causing the problem, even though Comcast had verified that all my signals were within THEIR specifications. Hence, the modem should not be rebooting. I can verify that Comcast was correct about my signal and power levels, as I have been with Comcast for well over a decade and constantly monitor the signals myself.Apparently, the Arris upload power level signal specifications for the SB6183 modem are just a little tighter than the upload signal Comcast can provide to my location according to Arris. Hence, their modem detects this and periodically drops my internet connection and reboots. This made no sense to me as the Arris modem is also Docsis 3.0 certified, and IS certtified to use with Comcast. I believed the problem lied with the Arris modem.I finally did return the Arris modem to Amazon and bought this new Netgear CM600 modem. After 2 days of use, no dropped connections, and no reboots!It appears the Arris SB6183 modem was the problem. Whether that was due to a defective modem, or the fact that it cannot tolerate normal Comcast signal fluctuations to my location does not matter. It did not work, and Arris was pointing the finger at Comcast’s signals. I have had NO such issues with this new Netgear CM600 modem. In fact, this new Netgear modem has more Download and Upload Channels than the Arris modem since it was only recently released. The reason I mention this is that Arris also told me that in general, the more channels a modem has, the more finicky it is about the type of signal it receives. That is why my older Motorola SB6120 modem with fewer channels never experienced the dropped connection issue I was experiencing with the Arris SB6183. Yet, this new Netgear CM600 modem has been rock solid stable without a single dropped connection thus far, and has even more channels than the Arris SB6183 modem I just returned. Consequently, this appears to be an Arris design issue (they insisted the modem was operating normally), not a Comcast signal issue as Arris implied on the phone.Additionally, this new Netgear modem is also much more elegant looking, and matches the color of their routers which are also of high overall quality. I also have a Netgear Nighthawk R7000 router hooked into this modem. The indicator lights also look way much better on the CM600, and are of just the right brightness when compared to the Arris SB6183 modem. Another important feature is that the ethernet light BLINKS during data transmiision through the Netgear CM600 modem. For some odd reason, Arris removed the blinking property from the data tramsmisiion light on their SB6183. The light just stays on without blinking, giving no indication that data is actually being transmitted. In my book, this blinking helps to confirm a good interenet connection, even though Arris would say that the fact that their data transmission light “just stays on” without blinking also confirms that. The blinking feature adds a bit more icing to the Netgear modem feature set. I suspect this removal of the blinking property of the data transmission light applies to all current Arris modems. Older Motorola modems always had blinking data transmission lights. In fact, this is the first modem I have ever seen without one.The lights are also much more gawdy looking on the Arris SB6183. The Arris modem casing also has an unsophiscated bright white color, and also has a rather unremarkable bland square shape. It rather looks like a child’s toy, not a piece of sophisticated hardware. The Arris modem also appears in general to have a cheaper look, design, and feel to it.The Netgear CM600 modem looks much more modern and elegant and has a power switch (Arris does not). It actually appears to have some thought behind its appearance and design.The bottom line here is that you should get this new Netgear CM600 modem. I have always used Mororola modems in the past, but that was Motorola, which is why I instinctively (without much thought) initially purchased the Arris SB6183. Arris sometimes likes to label their modems as Arris-Motorola rather than just Arris. They understand that Motorola’s modem division enjoyed a very good history and reputation in the industry before being taken over by Arris. That was then, this is now. The jury on how Arris handles their acquisition of Motorola’s highly regarded modem division is still out.However, given the experience and problems I have just had with the Arris SB6183 modem; its constant disconnects, its rather cheap look and feel, its lack of certain features, and the fact it could not handle the same signal Comcast has provided me for well over 10 years, I will be sticking with Netgear for now.This is the modem to get if you have Comcast, or one of the other certified ISP’s for this modem.It really is that good, on all fronts, including appearance, performance, features, ergonomics, and design.Kudos to Netgear.UpDate 11/12/15: Still NO dropped connections and great performance. Can I give this modem 6 stars?!
