My suggestion is don't think about wireless no matter what

Just because everybody can hijacking your wireless system. Juse use cable.

From security point of view, cable is the minimum reuqirement and it is cheap. If you want to use wireless, you have to use strong encryption scheme which normal users can't afford it.
