wanted to go on to wi fi. PC is hard wired so no router. got a USB wi fi . Then found that it needed to see Wii to work. Ok got a USB extender took cable in to line of sight & all worked.So far so good. Put cable still connected on top of PC so no longer has sight of Wii & guess what it still works. Removed from cable & put in to PC it fails ! the difference is it is slightly higher - moved up from usb port to top of PC . But it is now under metal desk & behind modem .
