BobtheFisherman, and/or Niel, I regret to say I am back. I've searched for the answer to this one too, but not found it, though have already tried a number of things.
I successfully installed Windows XP and everything works fine. But I can't get the broadband connection to work through Windows, though it recognises my network.
I have done various things and at one point did get the 'Validating Identity' message (which seems to be an XP problem) to change to something like 'little or no connection'. It did seem to accept the WPA key after various elaborate attempts, but I have never got as far as being asked for the password, which is what I would expect. I'm using a Netgear router -- could it be that I need to set up the router again using the disk while opening in Windows?
Or could it be a driver problem? The wifi access is still working fine on the machine from OSX if I swap back.
Any ideas welcomed. Should I have opened another question or it is okay to continue in this thread? Sorry to come back so soon!
