I bought this cable modem after some study and evaluation of popular cable modems for sale. I decided to buy it because I don't like the preset configuration of the Spectrum cable modem that comes with the Spectrum subscription. I prefer one that is not pre-configured and I'm glad I bought my own cable modem now that I have it. I went to the Spectrum website to find pre-approved modem models that are compatible with Spectrum equipment (you can do this with any cable company). I found that there are a lot of modems that are compatible, and I selected one based on the speed of my account and the price. I run about 300 MB/s speed, so I selected the Netgear Cable Modem model CM700 because it's rated for at least 400 MB/s and the price was very reasonable when compared to the competition. I was pleased with the CM700 right out of the box. It's much smaller than most other cable modems, and like most, it's mindlessly easy to hook up. It has a power plug that goes to a 110 volt AC outlet, a cable plug that goes to the cable outlet on the wall, and an ethernet plug that can plug into a PC, or a router/wireless router, or even into a network switch (gigabit switch). Once I took the CM700 out of the box, I looked at the quick-start guide, and I had the CM700 set up and running in less than a minute. I tested it, and it gives great speed too. The CM700 plugs into my wireless router (the uplink plug). It feeds the wireless router and a PC that is wired directly to one of the wireless router ethernet output plugs. The wireless speed I get from this set up is excellent, and the direct-connect speeds I get exceed my expectations. Look at the pictures, and you'll see from the quick-start guide how easy the CM700 sets up. The only criticism I have of the CM700 is that it seems to run warm, but then again, it has no malfunctions whatsoever. Also, I'm guessing that it has a great internal heat-sink, and I see that it has lots of holes for air ventilation, so that keeps it within the operating temperature range. Overall, I rate the CM700 a 5 star unit, based on both performance and price.

I'm a tech hobbyist but this was my first time setting up a modem and NETGEAR router for my home; I was extremely impressed with how easy the setup was! There's a quick start guide with about 8 steps that shows you how to set up the modem and then the router if you would like WiFi. I paired this modem with a NETGEAR 4-Stream WiFi 6 Router (RAX15) and the signal strength is a lot stronger and loads Netflix faster than the equipment my cable company gave me (their modem was made by Arris and their router was D-Link, I feel these were mediocre boxes). My internet plan allows for 100mbps download and 35mbps upload; I receive that basically wherever I am in my condo now! The modem does say 500mbps max download for wired via ethernet; I have my desktop wired and it claims the speed is 1.0gbps (which is 1000mpbs) not sure why it is doubled but I'm not complaining! The only thing is this modem does not have a port for the telephone line; though this does not impact me because I do not have a landline. For anyone that does though, just be cautious of this device! Otherwise, I think this is a fantastic modem and I would recommend it to anyone looking to upgrade their home internet; stop paying your internet provider to rent their cheap equipment and just pick this up instead!

I've used since this 2019 without issue. I just upgraded my wi-fi router from a R6080 to an RS300 and my download speed is now about 5x faster! The old wi-fi router was creating a bottleneck for the CM700. This CM700 has far outlasted any previous cable modems I've owned.

This review is specifically on a REFURBISHED Netgear CM700 modem. I post my process in case it might help just one person in the future because I know it is easy to get frustrated with tech when it doesn't work. Long story short, after several hours on the phone with tech support from Spectrum, we concluded that the ethernet port was faulty. Long story, long, I thought I would save a bit by buying a refurbished model. Amazon typically does a great job at certifying refurbished equipment, and I've bought several things as "very good" or "like new" before with no issues. This, however, did not end well. Physically, the modem looked fabulous. It is also almost fool-proof to set up. There are 3 ports on the back of it: one for a power cord, one for a cable and one for an ethernet cable. I'm pretty savvy on tech set ups, and this was straightforward. I unplugged my router. Unplugged my Spectrum modem and removed the cabling from the back. Replaced the ethernet cable with a new one (included in the package from Amazon, thanks). Screwed on the cable to the back of this modem. Plugged in the power cable. The unit powered up fine and went through its start up phase. There are 5 lights on the front of the modem; power indicator, download confirmation, upload confirmation, connected to the internet, and ethernet connection. All 5 lights need to be green to operate completely. I got to 4 of 5 lit and figured now was when I needed to turn on my router. I plugged my router back in and it went through its start up phase. At no time did the ethernet symbol turn green. No internet. Spent a couple of hours on the phone with Spectrum (my internet provider) billing and tech support. They had to add the modem to the account so I gave them the MAC address, printed on the bottom of the modem. The tech guy pulled up the user manual on both the Netgear modem and my Linksys router to help troubleshoot. After changing out the ethernet cable to the one I knew worked before, plugging it directly int my laptop, with no change, several resets and restarts, we concluded that the ethernet port on the modem was physically faulty - most likely the reason it was returned to Amazon in the first place. Amazon was great about the return. I will continue to purchase refurbished items in the future, but in this case I have ordered a brand new one. I expect it should be straightforward and connection should be simple. Fingers are crossed. UPDATED: I purchased a new one and it arrived the next day. Sure enough, it was easy-peezy. The Ethernet port light operated like the other 4 lights and connected almost instantly. Yay!

Reminder: it's just a modem. If you want Wi-Fi, you'll have to get a wireless router (and make sure it can handle the capacity of the modem or there's no point in having a relatively high-capacity modem). This was very easy to set up. It took a little while to get everything up and running, but that was because I had to call my ISP (RCN) and have them validate or recognize the modem before I could use it. That was time-consuming, but I can't dox this product for that. The modem is very small and kind of cute in a Darth Vader sort of way. The signal seems very good and reliable. A few notes on setup: the instructions assume you do not have an ISP already, so the first bit of instructions are about getting one. It's a little odd. Depending on the phone response time of your ISP, which, let's face it, is rarely very quickly, you might want to get on the phone with them before you start setting up the modem. That way, you can spend the time waiting for tech support physically setting up the modem and connecting it to your cable, getting the power supply how you want it, getting the ethernet cable plugged into your computer, etc. They recommend plugging the ethernet cable into your computer before you plug it into your Wi-Fi router. I have to agree, but you can still get everything ready to go once your ISP validates the new modem. Note: you may think this whole process will not take very long, but remember, if this is replacing something, you will also have to reset any device that you have linked to a previous router and wi-fi system. One suggestion I read said to change the name and password of the new system to be the same as the old system so that, for example, your smart items (plugs or whatever) will just transfer over. But that didn't work. I had to reconnect all of my smart items and redo all of my Wi-Fi connections on my phones and tablets and laptops. It took time.

Seems extremely fast, and was at a good price point! We will be able to continue to use this product as we upgrade our speed from Comcast! My advice to anyone installing cable modem, get the fastest, very best one you can afford. 32 channels down and 8 up means NO latency! A speed test shows we are getting 96% of the available bandwidth, which, is about the best you can, there is always "overhead" from the data packet itself that comes along for the ride. We were broadband internet cable users when it first came out in the early 90's. We went away from it in 2007 because of the unpredictable internet speed at any given time, and went to DSL and then ultimately, U-Verse technology when it was available. While DSL is consistent in it's speed, it is slower. In our area, U-Verse could only offer a max of 25 mbps speed, which is definitely too slow to stream video and maintain an internet connection. Comcast sure has fixed their unpredictable speed problems with "channel bonding". So far, we have NO issues and at 100 mbps, can easily have multiple streaming video channels at once AND decent internet speed. And, the higher speed service from Comcast is about $25 mo cheaper than AT&T, who provides terrible customer service. Comcast is much better at that. Hope to NEVER do business again in my lifetime with AT&T. The planet needs to shake that foul company off itself like a wet dog. Good day!!!

The Amazon site FALSELY claims it works with ALL internet providers. My story: My old modem and router combination was not working well (with TDS Service) (Fall 2020). The old ones had worked fine the previous 2-3 hears. The TDS tech recommended getting a Netgear Router (N600) and Netgear Modem (Sept,2020). I received the router on Sept 11, and the Modem on Sept. 12. I set them up and started using them on Sept. 13. The results were terrible. The connections continuously turned off. Sometime I could restart, and sometimes I would give up--and then after a bit, I would have a connection. On 9/21, a TDS technician came, checked, and could find nothing wrong. But the problems persisted. Although I could get a connection intermittently, I often could not use my email, and it would stop working in the middle of a project.-- Sometimes able to reconnect, and sometimes not. Two or three times, I called TDS, and they would fix something, and it would work OK for a couple days. On 10/13, a new TDS technician came. He said that NETGEAR modems would not work correctly with TDS. He gave me (trial basis) a new modem/router combination. The on and off problem persisted. On 10/14, this second technician came back, found there was something wrong with the modem and replaced it with a different modem/router combo unit (ARRIS). He told me to send back the NETGEAR modem, get a modem from another company (ARRIS, and one other, but NOT Netgear , but I could retain the Netgear router. The TDS Modem/router (ARRIS) has been mostly working (95%). And the speed is much faster than it had been--25% faster and about 100-110% of what I am paying for. Today, 10/16, I game to Amazon to attempt to return the NetGear modem. It tells me I should have returned it within a month of when I bought it, and I am a few days too late to return it. I haven't contacted Netgear yet, and that is my next step. It's very annoying that I have wasted a month trying to get the Netgear equipment to work, and now I find out its too late to return it to Amazon.

As a 20 something year old, I am all about saving some money, even if there's a decent upfront cost to saving money. I've had Spectrum cable for the past 5 years and have always used my own modem to save myself from the monthly modem rental charge. Two years ago my area had a huge speed increase in our internet offerings which resulted in the need for a newer Cable Modem that was capable of handling faster speeds. NOT ALL CABLE MODEMS ARE CAPABLE OF THE TOP TIER HIGH SPEED INTERNET My package was the 300x20 which led to me needing a new modem which is when I bought the Netgear CM700. Got it delivered, called Spectrum and gave them the MAC address of the modem. Boom. Up and running at my 300x20 speeds in 30 minutes. You don't do much with Cable Modems once they are installed but this one has worked great for almost 2 years now with absolutely no issues. It has a great design to look modern and has a good base to hold it up. Highly recommend if you are looking to not pay your ISP their monthly charge for a cable modem rental or if your current modem isn't giving you your desired speeds!
