I have a Toshiba M105. I went to Office Depot and bought the cheapest card, an 'ATIVA Wireless G' (pcmcia), which cost $29.95 USD +tax. It contains an Atheros chip. At a hot spot in a local coffee bar, it screams. I have never seen anything work so fast. [At first, it worked faster in Xandros4, but I changed the preferred servers to OpenDNS servers and I haven't looked back. This was based on a tip I found after searching the 'net.] The next cheapest card was $49.95. But the NDISwrapper has the Atheros driver by default, IIRC.
