    This is the best way to limit the amount of money that you give to comcast. Some of the features of a comcast account won’t work without using THEIR modem. But those features, for the most part, are ones that the average user just doesn’t have a use for.

    This modem is AMAZING! If you have many wifi devices and are doing heavy streaming, this modem will fix those issues provided you have good speeds from Xfinity and a good router to go with it. All 3 pieces are important to get optimal benefits. If you have fast interest speeds but a modem that can only handle so much, then you will experience issues. So make sure you buy this modem to handle all the devices in your household but also make sure you have a good wifi router and appropriate speeds from your internet service provider

    Its a brand new modem model and unfortunately spectrum doesn't have this in their system. So I couldn't activate it. 5 stars for bestbuy for taking it back and issuing a refund without any hassles.

    Which is more than I can say about the Netgear modem. I have not tried the Arris modem so I cannot compare it to that one. I’ve used two of these now at different locations and they do the trick.

    I upgraded to this modem because i am on the 1gb Xfinity service and it is exactly what I needed. Setup was very easy, and reboots are very quick. I consistently get just under 1gb (975, 945 etc...) when I check the output of the modem.

    I would say you will not be disappointed buying this cable modem. My home Wi-Fi speed increase dramatically and you will feel so much better with good internet speed. You need to call Comcast to initially set it up but it is quite easy.

    Solid modem, no issues so far. Able to use moto's admin dashboard to trace connection errors back to ISP. Bests my old Netgear CM700, status lights are clear and understandable, doesn't feel/look cheap. Expect this to last for a few years at least, which includes a manufacturer 2-year warranty, double that of Netgear (only 1 year).
