Hmm. I, too, have been having odd problems with the wpa_supplicant at
various times.
The clear problem you are having is that the weptxkey is not being reset
correctly. The first ifconfig shows it as unset. The remaining examples
show it as being '4', not '1'.
The only oddity I see is that you have the line 'wep_tx_keyidx=1
twice. I have no idea why this would cause any problem, though.
I have a different issue, but I "solve" it by entering
"/etc/rc.d/wpa_supplicant restart ath0" until it finally works.
