Works perfectly with Xfinity (my ISP - internet service provider). Am changing service and need something different.
this is a docsis 3.0 modem that will get you speeds more than you most likely have today in your program. The modem is capable up to download speeds of 343 mpbs (mega"bit" per second). So if you ever have to want more download (or your ISP / Xfinity bumps it up for free) you'll have equipment. If you are renting a modem, I saved hundreds of dollars many fold over the past decade having my own equipment and not renting from the ISP.
Approved on Comcast Xfinity, Spectrum (Charter, Time Warner, Brighthouse Networks), Cox, Mediacom, Suddenlink and most other US Cable Internet Providers.
Comes with power cable only.
