For example, if you use wicd, the configurations will likely be in /var/lib/wicd/configurations/<MAC> and look something like: ap_scan=1 ctrl_interface=/var/run/wpa_supplicant network={ ssid="JHotel" scan_ssid=1 proto=WPA RSN key_mgmt=WPA-PSK pairwise=CCMP TKIP group=CCMP TKIP psk=<a long string of hex> } Cheers, David.
