If you have Comcast Triple Play or Xfinity Voice, then you must buy an approved voice modem such as the ARRIS SVG2482AC or Netgear C7100v Nighthawk. Or the Netgear CM500v if you plan on using a separate router. If you have Xfinity Triple Play, there is no way around buying a compatible voice modem. Sure it may cost more up front but it will still save you money in the long run because you will no longer be paying the $10 a month rental fees. It will also provide you with the newer technology and more advanced higher performing wifi cable modem with built in wireless router. The good thing is, the Netgear C7100v is a combo modem router, meaning you do not have to purchase a separate wireless router, you get both in one device. A high speed 24 downstream channel DOCSIS 3.0 EMTA voice modem, and a powerful wireless gateway for Comcast Xfinity Triple Play Internet.

You will need your own router
What if I am not using the voice line? Do I still need a voice modem?
Yes, you do. I called Comcast myself and the bottom line is if you have Xfinity Triple Play– whether you use it or not– you need the voice modem. I have had readers also report that they tried and Comcast would not let them use a normal DOCSIS 3.0 approved cable modem.
Is this my only option?
If you have Comcast Voice Triple Play, then yes. You must use one of the 2 telephony compatible voice modems. Your options are very limited but the Netgear C7100v is a solid DOCSIS 3.0 EMTA modem, meaning it is fast enough for Comcast packages all the way up to Extreme, Comcast Blast and Performance. Get the best internet speeds Comcast has to offer and they have a built in Wireless AC router. Which one would we recommend? The Netgear C7100V no doubt. See the differences below in the comparison chart.
Arris SVG2482AC vs Netgear C7100V Review
In any given situation I would pick the Netgear C7100V over the Arris SVG2482AC. The C7100v has a Broadcom chip while the ARRIS SVG2482AC has the flawed Puma 6 chip and is on the list of bad modems. This is pretty big because even after they released a firmware update, users are still reporting latency spikes and internet slow downs. Making the very popular ARRIS voice modem, a bad option.
But even if the ARRIS SVG2482AC did not have a bad Puma 6 chip, it would lose this battle for many reason. One, the Netgear C7100v is a faster combo modem / router, it has built in USB ports for network storage, and the battle tested Netgear GUI and firmware. Yes, the ARRIS SVG2482AC voice modem may have two physical USB ports on the back of the modem, but they are not for your use. They are for service technicians and will not host an external hard drive or printer. The firmware just isn’t supporting it. I consider this a huge flaw. They make no claims of the device even having USB ports in any of their marketing, yet you can see they are there for service techs. This is the sole reason why I would get the Netgear C7100V. I love my network storage and back up. Rest easy, never lose a photo or document.
The USB ports are not the only enhancement with the Netgear C7100V. As you can see it has a slightly higher wireless throughput, which may be pretty unnoticeable if at all noticeable so do not let your decision ride on that. If you’ve ever owned a Netgear Nighthawk router before, you’ll be familiar with the Nighthawk built in software and I do prefer it over Arris’s GUI. That’s pretty much the general consensus with most people in tech. So when it comes down to the higher cost you have to ask yourself, do you need USB ports, want a better GUI / firmware and care about a small speed increase that you can’t even notice unless you’re transferring large files over your local network? For me, the answer is yes.
- Broadcom Chip
- USB Ports
- Faster Wireless
- Better GUI
- It’s Netgear
- Puma 6 Chip
- No USB Ports
- Slower Wireless
- ARRIS GUI
- It’s ARRIS
Netgear CM500V Vs TM822R Comcast Voice Modem
You’ll note that these modems are a lot cheaper. That is because they are not a combo router and they are solely a stand alone voice modem to be used with Comcast Xfinity Triple Play. This is great for me, because I prefer to use my own router. But what is the difference between the CM500v and the TM822R? Speed, age, technology. The TM822R is much older and only has 8 download channels where the CM500V has 16 download channels, yes double the bandwidth. Because they are essentially the same price, it is always suggested that you get the Netgear CM500V with your own router. Preferably anything AC1750 and above. These voice modes are fully approved and compatible with Comcast Xfinity Voice Triple Play packages.
|ARRIS vs Netgear:||SVG2482AC||C7100V||CM500v|
|Combo Modem:||Puma 6||Broadcom||Broadcom|
|Wireless AC:||AC1750||AC1900||No WiFi|
|USB Ports:||None||(2) USB||None|
|Current Price:||Compare All 3 Prices|
|Sources: Comcast | Arris | Netgear|
The obvious conclusion, get the Netgear C7100v combo modem for Comcast voice unless you want to use a separate router like I suggest. Then get the stand alone CM500v and a router of choice. But do not get the ARRIS SVG2482AC EMTA modem. C7100v or bust.
