CE Geek,
Just wondering when you've got the Agere drivers working on your Izzi Pro? I have an Orinoco Gold card and the problem is exactly the same as that described for the PenCentra. i.e. the R3000 cab refuses to install, the R4100 cab hangs, you have to manually install all the required dlls, and then then the router refuses to assign an IP address.
Very frustrating!
