I have recently bought a 15" Mac Pro Laptop and connected it via Bluetooth to a Sony Loudspeaker. The speaker works fine with my desktop Compaq, Sony laptop and my Blackberry. However when playing music from my Mac, the music randomly distorts very badly . It will play ok for varying periods but sooner or later the distortion starts. If I turn Airport off the music plays perfectly without any problems. I therefore conclude that there is a conflict between my WiFi and the Bluetooth signal. My router is a Siemens 2.4GHz, my Laptop is 2.4GHz. Is this a problem. Advice to this novice would be most welcome.
