I have a Logitech K400 wireless keyboard for my Mac Mini to use for XBMC in my living room. On the website it says the distance is up to 33 feet, and I am about 10-12 feet away and it won't work. It works fine when I get only about 4-6 feet away. Currently I have my the receiver plugged directly into my mac mini which sits behind the TV on top of my APC power conditioner. Is there a chance that the power conditioner is causing interference with the receiver and thus be the reason why it's not working from very far out? Or maybe the keyboard is just getting old and worn out. If so, what would be a good bluetooth keyboard/mouse or trackpad combo? I'd prefer to have it in one piece.
