I would like to connect my HR20-700 wirelessly from my bedroom to network. My modem and router are downstairs so a wired connection won't work. What have others found brands and models use as a bridge/adaptor? Also, my HR23 downstairs is connected wirelessly but when I try to view videos or pictures through MediaShare, I just get 'x' or exclamation points and I can't view them. How do I get this fixed?
