Ok, i've tried fixing my interfaces file and using ifup, and also
changing ssid=any or ssid="any" in my wpa_supplicant.conf file. I've
appended the relevant output below. I suspect the problem might be a
hidden ssid, as Andrew suggested. When I use WinXP on this same
laptop, I get connected automatically to ssid SMU_PUBLIC. However,
this ssid does not show up when I run iwlist ath0 scanning (output
pasted below).
I will look into impriv, as suggested by the other Adrian. Any other
suggestions?
Thanks for your time,
Tyler
