There are several different versions of the eeePC and each has a different wifi
adapter, all Atheros. The Xandros on the eeePC is a highly tailored version of
Xandros with specific eeePC modules. Mine is the 900 and if I install 701
modules it messes up my system. The 901 uses a different processor and it has
its own modules that won't work on my 900. It sounds confusing, but suffice it
to say that Xandros makes modules for all of the models, most of which won't
work with another eeePC. When you remove modules for the eeePC you can install
Xandros 4.0 and if you try to add Xandros 4.0 it will replace some of the
modules.

The solution is to stick with modules for your machine and add the two files
that make it Xandros with KDE. This gives you the ability to switch between the
Easy mode (IceWM) and Advanced mode (KDE).

When you add another OS such as Ubuntu it usually detects the wifi and installs
the drivers in the Administration | Hardware drivers menu item. The camera works
in Ubuntu and the hotkeys work. You can add a module called eeeApplet in the
8.10 repositories that allows you to overclock and control the fan plus turn on
or off wlan, camera and card reader.

I used ndiswrapper at first but now there is a proprietary driver. As for
Xandros, I would not use it as long as Ubuntu is available. However Xandros on
the eeePC boots in 20 seconds, almost instant on. This is good if all you are
doing is using the web.
