OK, what did you put in it? (Obviously you'll want to replace the
passphrase and any other sensitive info when posting it here.)

How did it fail? What exactly did wpa_supplicant say?

Maybe. I believe the madwifi backend is no longer recommended; I
believe the wext backend should be used instead (-D wext). But that may
depend on your version of madwifi and your kernel. (IIRC, it's also
true that not all versions of madwifi CVS actually work well -- but I
don't remember any details. Maybe those issues have been fixed by now,

Or whatever other DHCP client you want to use, yes. Once wpa_supplicant
has a connection up and working, that is.

I suspect you can use the WPA-PSK network section (the first network
section: skip the global options) from the example config file:
but you would not need the priority. If you want to specify proto,
key_mgmt, pairwise, and group, set them to WPA, WPA-PSK, TKIP, and TKIP,
respectively (as in the first ssid="example" network in the sample
config file). But that should not be required if "iwlist scan" is
showing the BSSID and the right info.
