Logitech F71 game controller range issues

[tinpanalley]

Where I want to use the controller in my living room, about 10 feet from my desktop, I seem to not be able to get a clear connection with the wireless USB adapter on the front of my desktop. Is there anything that can be done to boost the signal of a logitech wireless device receiver without physically moving the tower? Some kind of range extender, some kind of antenna, etc.

Perhaps if the signal can't be boosted, is it possible to buy a long USB cord to bring the receiver physically closer to me? I only need it to go about 7 feet. It just seems silly to have a wireless controller that doesn't go any farther than a wired one reaches.
