I only wish that I had made the switch sooner, for the first time I am actually getting what I paid for in regards to my Internet speed, to tell you the truth it seems to be a little bit faster. I haven't needed to reset or reboot my modem yet since I changed over from the Xfinity gateway. I am a paralyzed veteran so my whole house is smart and I really rely on technology, previously I was resetting xfinitys Gateway three times a day just to get my plan speed or so that it would actually work. Now I am no longer paying Xfinity rent for a piece of junk that doesn't work. The speed from this modem and my wireless router together absolutely crush what I was getting before. I have had zero issues I totally recommend making the switch, you have to remember if you have a voice plan you need to get a modem with voice or you will lose your deal even if you do not use the phone. This is the obvious choice.

When Comcast informed me that my Arris 25 modem could no longer handle the faster download speeds that my system is now capable of, I jumped on the deal to purchase this recommended modem along with a generous trade-in on the old Arris 25. The transaction was handled smoothly by the Best Buy staff. In addition, the interest-free financing is a nice touch. Thanks!
