Thanks Steve,
I know these things are problematic and I'd like to avoid using one if at all possible, but right now it looks like it might be my only option. Believe me, if another solution presents itself I shall be on it in a flash ;D
I'm not sure why that chipset is showing as only 10/100 though. But if it works and gives me up to 50mbps, then I won't complain. I'll give it a try and see what happens.
Cheers,
Nathan
