I am now convinced that I will have to chuck out the Railtek WiFi card in my
(new) Asus EEE PC901 as it has no range and replace it with another. The
question is which one?

Members of the EEE User blog seem to be recommending a Gigabyte AirCruiser
N300 Dual Band Mini Card GN-W106N-RH but that doesn't seem to be advertised
here in the UK. There is also the thought that it doesn't handle the 108MB
band, which may become significant in the foreseeable future.

I have seen that a Gigabyte Aircruiser G GN W105-GS-RH is available (still 2
band) but this raises concerns of:

1) is it an obsolete model?
2) What chipsets do they use?
3) Are they supported under Linux?

Advice on these issues will be welcomed.
