I have got an Acer Aspire One netbook and I am after a wireless card that actually works well with ubuntu. The original card was flaky and disconnecting intermittently and so I replaced it with an Intel Wireless WiFi 5100AGN. Again I have had driver problems with this card, I am stuck running WEP with me providing the IP address etc.. It will not work with WPA at all. It's a strange one as the card works fine on other wireless networks and other devices work fine on my wireless network (Buffalo WHR-G54S running tomato firmware). In both cases the wireless cards are reported to be supported by Ubuntu.
Anyway, can anyone recommend the any wireless cards or chipsets that are most compatible with Ubuntu and a range of wireless access points?
