WPA_Supplicant at boot time....

Change that to
    ifconfig_ath0="DHCP WPA"

One more thing to note if your laptop can do suspend/resume:
wpa_supplicant spins on resume.

    ifconfig ath0 down

will kill wpa_supplicant on resume but you will have to
manually restart it [this is good enough for me so I haven't
gotten around to debugging the spinning issue]
