Re: Weird wireless phantom device

I think your call on VBox was the right one. I was running the latest 3.0.6, but I'd already been thinking of reverting to 2.2 because it's actually quicker and I don't need the new bits in 3.0.

So now having installed 2.2 again, there's no problems with the WiFi device. Bizarre bug, I'd never have made that connection.

Thanks, Rick
