Hi All! I recently changed cities and unfortunately, my current situation puts me on the opposite end of the house from the router (no ethernet available). I installed an airport extreme card in my 2008 Mac Pro (running 10.8.2), and had some connectivity issues. Put an airport express in my room to boost the signal and have so far had much more stable internet than I did before. Unfortunately, since the move, my bluetooth has become very erratic. It can (sometimes) pick up the signal from my trackpad and mouse, more the trackpad than the mouse, but the cursor movements are very erratic. I tested them both with my laptop and they work fine. The system report tells me the bluetooth card is installed ok, software is up to date. I went to delete the com.apple.bluetooth.plist file, but it was not there. Could that have something to do with this? The only thing I can think of is something to do with the wifi install, since that's the only thing that changed, but I suppose it could also be something unrelated. Thoughts?
