I'm ready to dip into the world of networking my HR20. I'm nin-ViiV. I have to go wireless because I don't have a network port near my HR20. I'm looking at 2 Linksys products and I'm not sure which is the right one to buy. They have the Wireless-G Game Adaptor (WGA54G) and the Wireless-B Ethernet Bridge (WET11). Which one?
