Q: QuestionI do not have any type of cable . I just need internet to play my game will this be good for it? Or do I need cable

Asked 6 years ago by Anonymous.

• A:Answer You must have cable internet service because this modem is for use with a cable internet service provider (ISP), like Xfinity. If you do not have a cable ISP, this modem will not work. You do not need cable television service, however, you must have cable internet service.

Q: QuestionAre all of your modems compatible with Spectrum and or Time Warner? If I have a wireless computer do I need a modem with ethernet? Or does it matter?

Asked 8 years ago by WannaKnow.

• A:Answer this is just a modem. it does not have wifi built in. you need to purchase a router separate or purchase a combo modem and router or called a gateway modem. should be compatible with those providers but always check with your ISP to make sure you can purchase your own equipment and what type they support. i believe they are just like cox and support your own equipment. however some tiers of internet may require a fast modem then this. only option to connect your computer to internet is Ethernet from modem to computer.
