Comcast Triple-Play Compatible Modems

We've seen many questions from Comcast Triple Play customers on which modem they should buy and this post will explain to you your options as of January 2016. For those not familiar with Comcast Triple Play, its a 3-in-1 bundle that combines Comcast's Internet, TV and Phone subscriptions. 

Now, we previously wrote about our recommended cable modems and recommended gateway (combo modem and router) devices for 2016 but because of the VoIP capability with Triple Play, you will need to get a voice-capable modem instead, also known as an embedded multimedia terminal adapter (eMTA).
An eMTA differs from ordinary cable modems in that it includes an analog telephone adapter which provides the telephone service. If you're a Triple Play customer and want to purchase your own voice-capable modem, there are really only 2 models available at the moment.

1. ARRIS TM722    

The first model is the older ARRIS TM722. This DOCSIS 3.0 modem has 4 channels and can support speeds of up to 150 Mbps. It doesn't come with a router, so if you want wireless capability, you will need to purchase your own and connect the devices. 

2. Xfinity ARRIS TG862G 


Unlike the ARRIS TM722 above, the newer Xfinity-branded ARRIS TG862G is a modem and router combo device. It has an 8-channel modem and a 2.4 GHz wireless-N router which together will be able to support speeds of up to 250 Mbps. 

The in-built routing isn't that great in our opinion, so you might want to put it in bridge-mode (disables the router) and connect your own wireless-AC router instead, for better performance.

Important note: There is also a non-Xfinity-branded ARRIS TG862G and you may not be able to activate this device.      


There are currently 2 available cable modem models that you can purchase and replace your rental if you are a Comcast Triple Play customer - the ARRIS TM722 and the Xfinity-branded ARRIS TG862G. Do remember to call Comcast and confirm that your area allows customers to use their own eMTA and that the model you intend to buy is compatible.

Now that you know your options, the question still remains, should you buy your own voice-capable modem or should you continue to rent for Comcast? Unlike the traditional cable modems, when it comes to the triple play package and voice capable modems (eMTA devices), it's a little bit more tricky.

If you're looking to save money, then you should definitely buy your own modem and it will payback over the life of the device which should be between 2 to 4 years. However, you should note that if you're facing any service issues, customer service will likely point to your purchased device as a possible cause.

On the other hand, renting from Comcast allows you to use the latest models, like the Cisco DPC3941T and ARRIS TG1682. These have 16 channel modems (instead of 4 and 8 channels if you buy your own), wireless-AC and telephony. Head down to your Xfinity store and swap your existing device for no additional cost.

So in conclusion, if you want to save money and are willing to sacrifice a little on performance, buying your own voice modem is the way to go. On the other hand, if you're willing to pay for better performance and peace of mind (customer support), then you should continue renting your voice modem.

We hope this post helps you decide which option to go with. In full disclosure, there are affiliate links to the 2 modems listed in the above article. As always, thanks for your support this past year. It has really helped to keep the site going.
