Best Xfinity Voice Modem Comcast Triple Play

If you have Comcast Triple Play or Xfinity Voice, then you must buy an approved compatible voice modem with a phone jack such as the ARRIS SVG2482AC, Motorola MT7711, or Netgear C7100v Nighthawk. We’ll also cover the Netgear CM1150V and CM500v if you have your own router but we’ll expand on the subject more below.

If you have Xfinity Triple Play, there is no way around buying a compatible voice modem. Sure it may cost more upfront, but it will still save you money in the long run because you will no longer be paying the monthly rental fees. It will also provide you with the newer technology and more advanced higher-performing wifi cable modem with a phone jack and a built-in wireless router.

The good thing is, the highly-rated 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. It is far superior to the ARRIS SVG2482AC, but we have a much cheaper option below.

First, the cheat sheet. A full chart containing all of the important factors for choosing a voice modem designed specifically to work with your Xfinity Triple Play package.

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 with a phone jack. I have had readers also report that they tried and Comcast would not let them use a normal DOCSIS 3.0 modem.

Is this my only option?
If you have Comcast Voice Triple Play, then yes. You must use one of the two 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.

Motorola MT7711 Vs Netgear C7100v

Here’s where the going gets tricky. On one hand, you have the much cheaper and newer Motorola MT7711 and on the other hand, you have the older time tested Netgear C7100V. Which one works best for you? Cheaper? Or one with added features?

While the Netgear C7100v is the clear winner as far as features go, the Motorola MT7711 is by far cheaper and will perform the same as the Netgear. The truth is, the Netgear really only has one solid thing going for it, USB ports. Now is that worth about an extra hundred bucks? To some, yes. For me, it is a requirement that my router has USB ports for a print server / external backup drive on my network.

But let’s be real, that is not going to be necessary for 90% of home users. So here we are, you and me, face to face with a final answer. You will want to get the Motorola MT7711 and save yourself some money. If you’re not a network nerd and you just want a cheap working device, you’ve found your modem.

Arris SVG2482AC vs Netgear C7100V

It’s almost not worth bringing the ARRIS into the battle, but many of you want information on this unit because it is one of the top retail modems. But what none of them tell you is, it has a bad chip.

Because of this, 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 slowdowns. Making the very popular ARRIS voice modem, not an option.

But even if the ARRIS SVG2482AC did not have a bad Puma 6 chip, it would lose this battle for many reasons. 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 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 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.

Netgear CM500V Vs CM1150V Gigabit Voice Modem

You would get either of these if you wanted to use your own router.
You may think these modems compare, but they are in two completely different categories when it comes to technology, standards, and performance. We’ll keep this very simple.

CM500V: Only good for speeds up to 200mbps.
CM1150V: Newest technology, DOCSIS 3.1 and the only way to get Gigablast speeds.

Best Xfinity Voice Modem Conclusion

The obvious conclusion is if your heart is set on a combo modem router, get the Netgear C7100v Xfinity voice modem. It is undoubtedly the winner between it and the ARRIS SVG2482AC. No competition when it comes to EMTA modems. But if you want the cheaper modem without USB ports, the Motorola MT7711 was just released and just for you.

If you want to use a separate router as we prefer, then get the standalone Netgear CM500v voice modem and a wireless router of your choice. But nothing below AC1750.
