You can find xp drivers for the wireless - below link - select xp OS - these drivers can be installed in compatiblity mode to avoid an issue with the installer & the W7 OS :
To install a driver or program in compatibility mode - right click the setup.exe file - click properties - click compatibility - check run in compatibility with vista/xp etc - check run as administrator - leave the rest blank. Start setup.exe and install.
Here is a solution : Have you tried the Fn+F2 keys, or enabling it in the BIOS - you can thk QDOS if this one works as i found it in the forums search -EEEPC.
You need to see the drivers available from links and posters on the EEEPC Forums, they have all the resources you are ever likely to find for your machine...
