David, I saw the same issue yesterday when testing my ath based
chipset on using wpa_supplicant.  I got to the point where I was
connected to my AP but loss my router/gateway.  My problem was
*probably* due to pilot error since I ran wpa_supplicant/dhclient
manually.

Are you going through the /etc/rc.d/netif start cycle and seeing this problem?
