use the bluetooth serial adapter. It is quite reliable.
I use IOGear GBS301 (about $65) on the AC jr and IOGear GBU321 (about $20) on my computer. They are both Class1 and will work up to 100 meters (300+ feet). I have not tried it that far, but my computer is upstairs, and signal has to pass several walls, and I'd say distance is maybe 50 feet.

I know this thread is old, but I just bought an AC Jr. as my first controller and was looking for a way to connect wirelessly. Doughboy, your program looks really neat, and I plan on using that once I get my new system set up in a couple of weeks.
Are there any threads on this site dedicated to this program? I'd be interested to see how others are using it and what their thoughts were.
