Don't know if this is relevant here, but just to nitpick: it's ofter the case that a wireless card is receiving correctly but not transmitting.  Successful assignation of an IP address means nothing at all beyond that there's some driver present that thinks that it's found some hardware it supports, and finding the router means that it's receiving, but not necessarily transmitting.

a) output of 'iwlist wlan0 [or whatever it's called] scan'
b) output of syslog when you try to connect
c) run wpa_supplicant in the foreground with debugging enabled
('wpa_supplicant -c/etc/wpa_supplicant.conf -iwlan0 -d') and report the
output and syslog, as well as your wpa_supplicant.conf (sanitized)
