A:AnswerIt is very easy to set up! You just need to contact your internet service provider (ISP) and provide them with the serial number and the MAC id so that they can send the signal to your new modem, just make sure the modem is compatible to your isp. It usually comes written on the packaging.
A:AnswerNo, this is just a modem, which means you need a wireless router to go with it, and information about compatibility with a Linksys 1200 is unavailable.
A:AnswerYes you do need separate wifi modem. You can either chose another modem with has both combined or chose a seperate wifi router to use with this. The benefit of separate router and modem is that you can upgrade one independent of the other.
