possible use ndiswrapper install 2 different nics?
 

I just used ndiswrapper to succesfully setup my atheros AR5006X wireless on SUSE 10.1. My wired Realtek RTL8109 doesn't show up as listed hardward. Can I use to ndiswrapper to also setup my realtek device or will that mess up my wireless?

is the realtek nic a wireless nic?
if not, then it won't show up as a non configured wireless interface at all, it will be listed as a network interface.

yes, ndiswrapper can be configured to handle multiple devices, though the RTL8109 is fully supported in linux networking.
