After careful research I ordered wireless PCI cards that were said to "work out of the box". When they didn't I realised that my vendor had said they were out of stock. They had been replaced by X-Micro cards, which are atheros cards. I've been following the madwifi instructions, and have got the to part of setting WPA-PSK. The final command listed in this section is /usr/sbin/wpa_supplicant -dd -D madwifi -iath0 -c /etc/wpa_supplicant/wpa_supplicant.conf or is it /usr/sbin/wpa_supplicant -dd -Dmadwifi -iath0 -c/etc/wpa_supplicant/wpa_supplicant.conf ? Either way, I just got dozens of lines of 'Invalid ESSID line' messages. What am I doing wrong? Anne
