Connecting my laptop to the WD

Can anyone tell me if I am hooked up to a wireless router that is connected to the wd do I still need to get a wireless USB card for the wd to see the laptop.  Also if I am watching a movie from the net can I also watch it at the same time on the TV through the wd.  Thanks

Which WD TV do you have?  Did you ever get help with this?  It seems like you are in the wrong board.
