CM700

This is an incredible modem when paired arithmetic the NETGEAR Nighthawk X-10 AD7200 router. Basic set up is very simple, a call to one of the supported cable companies and your good to go. Modem gets warm, especially when you got several devices drawing from it. I always mount a small fan on side of my modems to help with heat issues. Been a NETGEAR fan for many years now and this is the first cable modem I have ever owned made by them. Many Motorola modems over the years and this one seems to be much better than any of those I have purchased. I always buy my own equipment as the modems supplied by TWC/ Spectrum are not real great. Took one back after having it a week once and got another in exchange. The thing was already making a rattling sound before I left the TWC store. Took it back and have purchased my own equipment ever since. No monthly rental fees and no cheaply made junk that needs to be constantly exchanged. Only cons I have with this modem compared to others I’ve owned is it gets warm , dosent really show bonding like Motorola models (the arrows turn blue) and it’s built very well, but bottom seems a little unsteady. Has on/off switch which is a great feature for when you need to reboot equipment. Overall, very pleased with this modem. Did buy the protection plan for it as well. Updated June 15th, 2020 My NETGEAR modem is still working like a champ and it’s not having any issues keeping up with the number of additional items we have added to our home network. -We have two iPad Pro 10.5 inch devices running most all day. -We replaced our HVAC unit and have a Wi-Fi Thermostat running around the clock. -We have two iPhones connected to our home network. -Our receiver for the Surround Sound is connected to the NETGEAR S8000 assignable switch. -The Oppo - BDP 105 player is attached to the switch. -The Roku Ultra 4K player , which stays on nonstop now, is also connected to the switch. -I have a Oppo-UDP 205 that I play CDs through if I’m not watching the TV hooked to the switch. -I also have a HTPC that goes back to the Nighthawk router that decodes my MQA CDs -Our home automation system by Homeseer is continuously running off the modem. -We also have an Apple TV device that’s hooked up to the switch, but never use it. -I have a Astell&Kern Hi Res portable player that I also listen to Tidal on. -Our security system is also connected by Wi-Fi and with cellphone as well. -We have a NAS system hooked directly to the router with movies and music on it. -Lastly we have a Samsung Tablet and a Amazon Kindle also on our home network. The 2 iPads are on all day and the receiver as well as either the Roku or the HTPC are also on , so are the Wi-Fi thermostat and the two phones along with the Home automation system. We’ve had several other things running as well at the same time and the modem has never overheated or have we had issues with buffering or other issues. It’s mostly a lot of rack mounted items in a closet in my dedicated music room where my vinyl collection and my High end stereo system is located. The closet has a huge rack system that stays locked up and the modem and the router are also in this unit on a shelf. There is a NETGEAR switch in the 42 space rack, the NAS system. A computer that rarely gets any use now and it’s where the one Oppo-205 is located as well as the Roku and the Surround Sound receiver. It’s decluttered our living room and most all of our BluRay and DVDs are burnt to the NAS devices. We have the shelves built to hold the physical disk and CDs. Everything in our den that we use is controlled by an IR repeater. Even our cable box is in the rack. We have some other things as well like a Drawer mounted KVM smith with a screen, but it rarely gets much use since Windows Home Server was discontinued and the two identical servers I built are just not used anymore. We have Spectrum internet and it use to be the fastest one available, but since they took over Time Warner, they’ve added a newer speed. It’s not a need for us yet! But with everything becoming Wi-Fi or Bluetooth, we might have to upgrade to the faster speed. If we do, I’m definitely going to buy the NETGEAR CM1200 if I need to. I’ve noticed a lot of people who are having issues with thier modems. It’s more than likely your ISP as we had a lot of issues with ours and they have finally got the bugs out. We went through three different Motorola modems , all we’re having issues with overheating and Time Warner would not be able to ping them and get to our modem. I finally got tired of dealing with them and just about the time I was going to drop them, they were bought out by Spectrum. Since Spectrum has taken over, even though we still have Time Warner on our Bill, the service is more stable and we rarely ever loose our internet. We don’t have a house phone, but we are still paying a lot for cable and for streaming services. But the most important thing is that our equipment is not getting fried from the ISP now. It’s also important to remember that no matter if you have cable or satellite service, it all is coming from a satellite signal of some kind from some location. We’re now getting our cable from Austin and it’s much better than it use to be. We had issues with the cable box pixelating all the time. We have a six tuner DVR plus the HTPC has a Cable card device in it that records and through software plays back the recording in 1080p. We are going to get a 4K TV and receiver when this pandemic is over as well as a new 7.2 DTS speaker system. We have a 7.2 speaker system now, but it’s getting outdated. It just depends on what happens to our Country and what person becomes president! If the economy collapses then we’re not getting anything. But if the get the Administration free from corruption, then we will be buying a 4K system. I like the fact that NETGEAR has apps to control the router and I e never had any issues with getting tech support from them, even after my initial free trial ran out. I can reboot my router from my iPad and see what is connected with their apps. It’s just quality made equipment. Some may get a bad egg, but there are so many counterfeit items on the market these days, you may make sure you are buying the authentic item! We only buy our Apple devices from the Apple store or from Apple.com.

I can't begin to tell you what misery I've gone through in recent months with regard to my ISP and my download speeds. I'm paying for the highest level of Internet service, yet for the past few months, service has been getting slower and slower. Most of the time in the past couple of months (especially during peak evening hours), we were getting about 1 - 5 Mbps. That's it! Granted, the new development that I'm living in is growing rapidly, and our home has many connected devices; still, 1- 5 Mbps is absurdly bad for what I pay my ISP every month. After much troubleshooting over many days--too much to go into here--I had finally narrowed the problem down to the crappy cable modem that my ISP always gives me. I replaced the original unit that they gave us when we moved a year ago, but that unit died within a day or two. I went to the ISP's local store and demanded a brand new unit (and not just another "tested" and recycled refurb). Garbage too... still getting unacceptably slow speeds. I finally bought this unit. I love it. No more built-in-but-subpar-and-mostly-useless WiFi which I disable anyhow. No more built-in telephony--which is fine because we've been thinking about getting rid of the house phone anyhow. The CM700 does one job and does it fabulously well. This thing is stupid-easy to set up. After connecting to my ISP and getting the unit activated, I was back in business. Wow! I'm finally getting the speeds for which I've been paying my terrible ISP for over the past year. Because of our unique circumstances, I have no option (for now) but to keep my wireless router in the basement next to the cable modem. Still, even on the second floor in the master bedroom, I'm getting between 200-230 Mbps. On the third floor, it's about 80-95 Mbps in both bedrooms. (The house is about 3400 sq. ft.) A direct Ethernet connection is even crazier... a steady 275 Mbps. Absolutely fabulous. The results are so amazing that I've ordered another Netgear CM700 to keep as a spare. :)

Comcast told me it was time for me to update for faster speeds. I bought this modem and a new faster Netgear router. I had a small amount trouble getting things running but I look back and see that didn't follow the instructions properly. The whole setup is providing a nice wifi with better range and speed than before. The majority of the improvements came from the router upgrade, and the modem was on Comcast's list of approved equipment. I just assumed it would work and with its speed capacity it should be good enough for any new internet changes. I bought this model for very little more than another sightly slower one. Guess what. The investment made things better and keeps me from renting a modem. I will put me ahead of of the rental game within a year. My prior experience with Netgear equipment has been great although it was with much cheaper units and slower speed requirements. The units were a little to light and connecting the cables to them tipped them over. It was easily solved and the setup looks and is functioning great. I don't know what all the lights on the modem are supposed be telling me but I know that they are all on and everything is working fine. The setup was one of the cheapest ways to go that I could find with a separate modem and router and I am well pleased and I hope this continues for at least as long the old Neargear equipment which was replaced only because its speed requirements needed updating.

In all honesty, this is one of the more stable consumer electronics I have ever had. Easy to set up, easy to get into the web admin page. Only need to reset is because of external issues with Comcast signal quality, etc. Over 2.5 years of rock-steady performance. Only issues (as mentioned by others and in the headline here) is that it does NOT support anything close to 1.4 Gbit/s on Comcast. I got rock steady 720 mbps down on a 600 mbps plan (with the typical 20% Comcast overhead), but when they just upgraded blast to 800 mbps last week, the thing actually does worse. This was already a known issue to me when I briefly "experimtented" with their Gigabit plan (just to get greater upload speeds) and it was unstable and slow. So, I'm guessing somewhere less than 800, but maybe more than 600 mpbs is their maximum "sweet "spot". Have a Docsis 3.1 on order (by Netgear as well)... hoping to get the full 960 (800+20%) for the current plan and may upgrade to Gigabit (again) for $5/month more to get the 35 up instead of just 15 up (upstream speed increase definitely helps with my work activities over VPN). Hope this review helps even a little. Hit me up if you have any questions.

The NETGEAR CM700 was not on Time Warner's approved modem list at the time of this review (April 2017). This means the modem can't be activated using Time Warner's (now Spectrum's) online activation service. But the over-the-phone activation process took under 10 minutes. Pros: - Very well ventilated, so it runs cooler than my rental modem (Arris CM820A). - Will pay for itself in one year of saved rental fees. - Ethernet port is bright yellow. Sounds silly, but when you're reaching into your darkened equipment rack, a bright yellow port really helps. - I expect the 32x8 channel bonding to be future proof for my needs. Cons: - Should be mounted vertically for proper heat dissipation. Not an issue for me, but could make fitting in your equipment rack difficult (height= 6.75in or 17cm). - Boot/connection time is longer than expected. My cheap rental modem booted and connected in under 1 minute. But the boot/connection time for the CM700 is more like 2-3 minutes. This was a little irritating when activating it, and will be a little irritating each time there's a brief power outage or reset. Your connection time may vary depending on your service provider. I've had it in use for less than a day, but will update if any issues arise in the future.

Free technical support for 90 days. Called for help on day 103 and Netgear technical support tries to sell me support extensions - $50 to $100 ! I’m going to toss this one and buy a better modem instead. Technical support strikes me as strategy to sell support extensions rather than to help consumers: Update - Replacing the Netgear CM700 with an Arris C33 modem resolved the erratic wifi speed issue. Meaning, the Netgear CM700 appears to be defective. Research reveals the CM700 uses a frequently malfunctioning Intel Puma Chipset. And the malfunction produces the same sort of erratic wifi speed changes and green flashing downstream light that I was experiencing. “Buffer Bloat”. I suspect the CM700 gets stellar reviews because light weight usage - browsing, streaming - might not be enough of a load to reveal the issue. I suggest CM 700 users speed-check their network multiple times a day. If you get, for example, 485mbps on one check and get 40mbps five minutes later. And you are constantly seeing huge changes in speed, then I should think you’ve got a malfunctioning chipset. I believe my CM700 arrived defective. Don’t make the same mistake I did. Speed check this devil and make sure it’s working well before your 90 day service warranty expires. BTW, don’t use the eero app to speed test your wifi. Download a couple of reputable speed check mobile apps to do the job. Good luck with your CM700!

My boyfriend and I purchased this in a combo with "Netgear (R7000-100PAS) Nighthawk AC1900 Dual Band WiFi Router". We've been using it for a few weeks now and I must say, we are BOTH happy campers!! My boyfriend and I are both video gamers, not heavy into it but at least enough where we play a couple hours a night on our computers or on our separate X-Box's. We had a modem given to us by our internet provider (Timewarner/Spectrum) that we'd been using for at least two years, but we were having troubles with the internet being slow, even after repeated calls to Spectrum. Figuring our modem had just finally crapped out, we went to walmart and purchased an Arris surfboard and if anything, that made the problem worse to the point where I couldn't even look at Facebook videos on my phone while my boyfriend was playing on his computer. My phone constantly kicked me off the internet, and if I tried the xbox while he was on the computer, it would kick us BOTH off mulitple times. Again, endless calls to our internet provider, tried switching modems, nothing worked. Finally as a last ditch effort, we decided to go big or go home and purchased this and the "Netgear (R7000-100PAS) Nighthawk AC1900 Dual Band WiFi Router", as I stated earlier. No longer do we get kicked! In fact, it improved our internet speeds! I'm not a tech person, not with modems and routers and stuff like that so maybe we really didn't need to buy this but I can tell you that I'm glad we did. Would I recommend it to someone? You bet I would! I wish I could give it more than five stars. My boyfriend and I are both extremely happy with this purchase!

I use Xfinity Comcast as a provider. I recently updated my aging Zoom 5363 Cable modem wireless device. I also went to Xfinity extreme from 150Mbps to 250Mbps the Zoom modem is unable to handle this speed due to the filters and lack of down speed channels (8x4) . I decided to split the cable modem and wireless setup, so I added and Orbi wireless mesh wireless router. The CM 700 cable modem has 32 downstream and 8 upstream channels. Set up was a piece of cake, connected the modem called Comcast had it provisioned in less than 10 min up and running. At 250Mbps the modem was locked on 20 of the 32 available downstream channels and 4 of the 8 available upstream channels. I tested internet speed and was receiving 296Mbps Downloads and 30Mbps uploads! Truly Fantastic! Next, I installed the Orbi WiFi router mesh system it is a great product AC3000 and tremendous speed improvement in my wireless network speeds and coverage throughout my 2700sq home. I am a digital geek and have approx. 20 devices running on the system from smart phones (5) to smart TVs (4) to ipads to desktop and laptop computers. With these 2 upgrades to my system I now even see speeds up of 275.42 Download and 28.91 uploads at 14ms off my iPhone alone, needless to say I have seen an overall improve of almost 4-5 times greater downloads for my devices. I have been in the tech industry for over 20 years and this is simply on to the easiest setups I have ever experienced. This bundle will set you back about $500 but well worth the price given the speed and performance. WFI - I noticed a lot of incorrectly tagged modem reviews under the CM700 that do not seem to go product so take what you see with a grain of salt.
