Item description although I'm sure the seller is most likely not responsible for telling you this but should tell you that you also need a router. this product. (at least with xfinity) Not worth it alone. Also, there are only two Ethernet ports. I haven't used the product so I can't tell you how the product itself works. The lack of ports and the inability of the router is why I rate the product low.
