said by alan47:None of these. A cable card plugs into a special slot in a device such as a Tivo. It is the device it plugs into that requires the coax connection.
does it need a coaxial cable connection to it or does it work off of the router's wireless network or does it need an ethernet cable?
You don't specify what kind of device you're considering, but you will need a coax drop for that device. It can be split off an existing drop, or you can have another drop run.
There are 10 kinds of people in the world; those who understand binary and those who don't.

CableCards can be used for any number of devices. One of the most popular ones are Tivo, but other devices such as the Ceton InfiniTV tuner card for a PC computer and a SiliconDust HDHomeRun are also other options.
All of these need coax for the video input. They do not use Internet for video, but they do need Internet for the channel guides.
Yes, you can use a splitter for the coax and feed the coax to other devices. I have a splitter that feeds my TV (direct Clear QAM), Verizon's cable box, an Actiontec router, and the Ceton InfiniTV tuner card. All work fine.
