I think eth0 is representing the wifi card (it says hardware address .....) and the Linux entry in YaST (that I deleted prior to trying to setting-up the wireless NDISWrapper entry) made reference to the Wifi card.
I am definately not connecting via cable as I do not have an ethernet RJ45 socket on the back of my PC.
Regarding the alias I have not seen any instructions telling me to type "ndiswrapper driver.inf -a". I have only installed the driver with ndiswrapper -i /../driver.inf then modprobe ndiswrapper.
Hope this helps. I hope you can help me crack this as I am keen to see a fully working Linux installation, and hence bin WinXP.
Lets keep this thread going until we reach a conclusion.
