I'm having trouble diagnosing a problem using the Firewire port with an Edirol FA101 digital sound box. When I use it to playback wave files, there is a dropout every 60 seconds. If I disconnect the mouse from the USB port, there is a static sound added to this dropout.

If I leave a mouse connected and disable the Ethernet onboard and the wireless card (a Dell 1450), everything works perfectly.

When the wireless card is enabled (and nothing else), the dropouts return.

I disabled the 1450 and used a Linksys USB wireless adaptor - and it worked without interruption with the Firewire.

With the 1450 enabled AND using a PCMCIA VX pocket D/A adaptor for the sound, I was able to get perfect sound without a problem.

So any ideas on what's up with the 1450 wireless card? Anyone have any experience with the Intel a/b/g version?
