Way too much information!!!!!!!!!!!! Try again. What are you trying to do. Folks here don't like pulling teeth to get information. You have offered none.
As far as I know its mainly used for connecting cam-corders and stuff like that. Whats wrong with your normal connection? having a 400mbs connection between your computer and modem wont really make a difference unless your router/modem is on the other side of the world.
