So I've searched and found out that the bluetooth problem, with my Magic Mouse and Mac Pro 1.1 tracking issues, is common and a result of mismatched wires. So, before my airport card was working fine and my wireless connection was good, but my mouse was skipping. I had the #1 wire in the top airport slot, the #3 below it, and the BT label to the bluetooth card. The #2 wire was loose. As per what the forum said, the #1 should go to the bluetooth module, the #2 to the top of the airport card, and the BT labeled wire should be hanging free. I did this, and while it did solve my bluetooth problem, my airport wireless starting to act up. It would connect to the internet, but then pages would not loading and the connection would die and lag out. What gives? I returned it to what it was before, and my airport is working fine now but my mouse has the bluetooth problems. I even tried putting the #2 wire to the bluetooth, and the #1 and #2 on the airport, and while it worked, for bluetooth, the airport was still bad. #3 does not reach the bluetooth card. What can I do?
