Customer Ratings & Reviews

Working much better than the old pay per month Xfinity modem. Happy to purchase my own.

Love this modem but had to return. It wasn't compatible with COX. Here in Las Vegas. Had to get something else that was on the list of modems COX is compatible with. I bought my own modem to stop the rental fees etc. to bring my bill down.

Great choice to purchase. Did have some issues at beginning as would go off line but seems like they have fixed the issues. Speeds are higher than our old modem and saving the monthly charge from Infinity

Great modem compatible with Xfinity. Buy one outright rather than pay Xfinity a modem rental fee.

I am a Comcast Customer and this is one of 2 or 3 other that work with this company. I only wish this device can also be wireless. So far so good and no issues to report.

I had the Geek squad come and do the install. This thing works great. Also the great service in installing it was terrific. As far as I am concerned there is NO other place for me to shop. I have shopped at Best Buy for years and never had one bad experience.

Greta modem for modern internet. Works with Xfinity.

Never got a chance to use it, but they are a good bran the last 2 worked very well

Fast modem, some limit with using both ethernet ports in connecting router. Both needed for DOCSIS 3.1 speed as Comcast/xfinity customers. Used multiple ethernet ports from router without issue.

Works as expected, but beware that your computer will be what determines the actual download speed. I have 9 computers on my network and download speed varies from 350M to 975M. The telephone option works great and it is nice to be done with the Frontier's AC hum on the landline.

A perfect modem for extending my home network. Replaced my Comcast equipment for a fraction of the price.

was avery easy set up its compatible with what comcast uses and so far works great have no issues you do need to call comcast and give them numbers and information on what model it is and they r very helpful so highly recommend this product

Bought this to save $ on renting from Comcast. Only three weeks, but seems to be working very well so far. Comcast tested it during a service appointment at 989 Mbps versus their line at 1,002 Mbps.

I purchased this modem after reading reviews on it, I have Comcast and never really was able to obtain the speeds I was paying for with their modem I was renting. I paired this with a Night Hawk Router and now I have a very fast setup to do the things I want to do.

This is a great way to avoid monthly recurring from Comcast. Works as advertised.

Great modem ! Much smaller than my previous one. It's faster and I am very happy with it. I highly recommend this modem for Xfinity internet & Voice

Replaced an aging modem. The new ARRIS Surfboard is up and running and so far performs as advertised

Downgraded my rating because what could have been a simple plug & play install, wasn't. Comcast & Arris instructions/FAQ's/apps ask the installer to enter a CM MAC address. This unit doesn't list one. It lists an MTA MAC [for the voice] and a HFC MAC [for internet connection]. After multiple times of VERY careful reading, as I was installing this for internet only, I got the unit installed using the HFC MAC address.

I have not seen any problem as such with ARRIS T25 gigabit Internet & Voice Modem since I installed it about two months back. There are two Internet ports, but only one, either one is active at any time - contrary to what I believed initially.

Had a 10 year old modem that was very much in need of an upgrade. This bad boy definitely did the trick. Now i get the speeds im actually paying for
