Review: solid emta modem for the price - I bought this modem to replace the tm822g from comcast. My setup had the tm822g and an asus rt-ac66u, however, due to an issue with comcast I wont go into, I was being charged a rental fee for a modem that I had purchased. All of the other modems that were compatible with comcast did not offer the emta for voice so I was faced with either buying a modem and paying for a triple play that had voice i couldn't utilize. or pay 250 dollars for an arris that had emta but was based off the highly controversial intel puma6 chipset which has been documented as having flaws and being unstable. On top of that, all the devices that had emta were all in one gateway devices that provided routing and wireless which I did not want. I wanted a lean modem that literally only did modem and voice things. After some arguing with comcast they told me the cm500v was coming out in approximately 1 week and it would be what I am looking for. The CM500V has 16 downstream channels compared to the 8 channels on the tm822g. I do not notice any difference in top speed with this new modem as the bursts seem to cap at around 240mbps. It does seem though that when the modem is under load it seems to handle it better having more downstream channels to spread the bandwidth over. This modem does future proof a little as it would be adequate if comcast decides to up the speed to 686mbps at some point. Although, if that were to happen I would need to replace the AC66U because the CTF hardware acceleration on packet switching from the wan tops out around 300mbps. That all aside, I had no problem installing the modem. I plugged it in and it booted up and I was directed to the comcast walled garden. I put in my account information and it rebooted and was working within minutes. I did not have to call comcast. Once the modem was working I plugged it into my router and then I lost wan connectivity. Once I rebooted the router and the modem everything was up and running again. Since I was plugged directly into the modem from my laptop when it first booted up it got an IP address based on the MAC address of my laptop. That was why i lost connectivity when i plugged it into the router. Once I rebooted them both the modem pulled a new ip address and everything was good. The modem has been rock solid since with no issues on the phone or voice side. If you want a modem that is literally only an internet and voice modem that doesn't do any routing (because you have your own routing hardware) and doesn't have wifi (again because you have a router or an AP for that) than this modem is adequate and fits into a nice price point. It also is based off a broadcom chipset and is not susceptible to the issues people are reporting on devices that have been based off the faulty intel puma 6 chipset like the arris 6190. There has supposedly been promised a firmware update to fix the 6190 but it has yet to be seen. The arris 6183 is not affected by this issue in fact, the 6183 uses the same broadcom chipset the cm500v does. The key difference is that the cm500v has voice and the 6183 does not. The 6183 is one of the most popular retail modems and this devices is every bit its equal despite its slightly higher pricepoint, which as you may note, is because of the emta functionality the 6183 lacks. So if you need a reasonably priced 16x4 channel modem that doesn't have all the bells and whistles of the gateways the ISPs try to rent you and you dont have voice service from comcast, you can get an arris 6183 and save a few bucks. If you however have a triple play with voice, this modem is basically a 6183 with voice. If you check the datasheets its the exact same broadcom chipset. If you feel the need to check the webUI of this modem you will find its very simple and there isn't a lot you can do from there other than check the status and reboot the modem. The webUI is very lean on functionality. But honestly, I dont consider that an issue because as subscribers to an ISP we dont really handle any of the configuration anyway. The modem downloads the docsis config form the ISP when its provisioned so really that point is moot.
Review: Modem is excellent, but was a task to set up - I had a heck of a time getting this set up. First, I downloaded the user manual before doing anything. (Netgear doesn't include it in the box, but that's okay with me.) There is also a Quick Start guide. I chose to follow the more extensive user manual, which was a mistake. The user manual instructs you to log on to your ISP's website (they include a table with all major ISPs) to activate the modem once you've hooked everything up. Everything worked well (internet and telephone) once I hooked everything up, and I was able to log onto Comcast Xfinity's activation website. It seemed to work, but I was never prompted to provide the modem's model number and MAC addresses. This worried me, per some reviews here, that my internet and phone would go down soon if I didn't contact Comcast. The Quick Start guide didn't give any website addresses, but only said call Comcast to activate it. So, I called, and the automated system asked if I wanted to activate a device. I said "yes," and the system sent a reset to my modem. Nothing worked after that. Then I called the dreaded customer support. After almost 90 minutes, the CS rep got my internet back up, but the not the telephone. The rep finally told me he was escalating the issue to "Level 3," and that I'd hear back from them within 24 hours. What, go without my phone for 24 hours, and no guarantee that they'd get it working? Nope, no way. I told the rep to deactivate the CM500V, and I hooked back up my Comcast/Xfinity modem/telephone tower (the thing is really big) to make sure things were back to normal, but decided to try one more time. The second time I followed the instructions in the Quick Start guide rather than the user manual. I first reset the modem to factory settings just in case something had been modified that I wasn't aware of. Next, I started everything up from scratch, got the internet and phone service working, but did not log onto Comcast's activation website. Instead, per the instructions, I called Comcast to activate it. The tech rep told me that it was already set up. I asked him if he had the hardware's MAC addresses and model number, and he said yes. I asked him how they got it, and he said the system picked them up automatically. It has been working like a charm. I hooked it up to a new router with no problems. Now that I'm up and running, I get much higher speeds that I was getting with the Comcast equipment, and I suspect that some of intermittent problems I've had with my internet are resolved now (such as being inexplicably disconnected form some web sites, sudden slowdowns, etc.). I have better control over my technology now and am saving $11 a month on top of that. It appears (and I use that word with caution) that Comcast has actually streamlined the setup of this modem, and possibly others, by automatically picking up the hardware info. In the end, I'm very happy, and love my new Netgear modem.

### ⭐⭐⭐⭐⭐ solid emta modem for the price

### ⭐⭐⭐⭐⭐ Honestly, it's quite possible this modem performs well above the specifications it showcases.
*by B***E on August 7, 2018*

We use this in an art studio that designs branded material for clients, and that being said, all of those designs are privileged. One thing that's absolutely unacceptable about many of the modem offerings is that Wi-Fi is embedded as a feature, and since xFinity ( a.k.a. "Comcast" ) can reset the modem and blast whatever security settings "were" in place for those particular offerings, having a modem like the NetGear CM500V is absolutely necessary for those that require protection of their data and relevant systems. While we were initially disheartened that the NetGear CM500V seemed to have a limit of 680 M/b p/s at the point of service, and in specification is DOCSIS v3.0 and not DOCSIS v3.1 , any wary feelings have since dissipated. The operating speed has been tested to have achieved almost 1 G/b p/s at the point of service while the embedded interface of the modem itself is so simplistic, even the xFinity ( a.k.a. "Comcast" ) service administrators have been unable to cause any trouble. In fact, the only thing we've had to do since we've had it is to periodically verify that the password we use for it is consistently in place during our regular security audits. If that's the worst we have to deal with being stuck with xFinity ( a.k.a. "Comcast" ) as our sole option for that particular office, as stark as this sounds, it's honestly quite refreshing. Additionally, the embedded administration Graphical User Interface for the NetGear CM500V logs every single thing in such a level of specific detail, it is much to the delight of those that perform security audits of ISP related equipment. Perhaps one of the NetGear CM500V's nicest features is also one of its simplest; that of course being its small footprint. While it is kept in a locked network closet, it was by no means a struggle to put in place, and the best part is that the modem doesn't get very warm either, so we're very confident the NetGear CM500V's going to last quite while. Perhaps the NetGear CM500V will even last long enough for the USDOJ to deal with AT&T's subsidiary of Comcast in such a manner to force other great service providers like RCN and FiOS to be able to continue unfinished infrastructure projects of their own that hold significant promise of improving internet access and internet service provider competition that will result in lower prices compared to the presently monopolistic pricing practices of AT&T and its ISP subsidiaries for all. All in all, that may be quite a while because as we all know, the USDOJ is fighting the recent acquisition of Time Warner by xFinity ( a.k.a. "Comcast" that is a subsidiary of AT&T ) , but like anything worth doing, it'll be a hard wait, but it'll happen when everyone least expects it. When all is said and done, our NetGear CM500V will in all likelihood, still be sitting pretty processing data reliably, we'll just have to double check the password setting again of course. ;)
