I am getting a similar issue. My wireless will stop working (connected, but no transfer) from time to time, and a few times it has resulted in a system hang. It seems to primarily happen when I am downloading torrents with deluge. I am using an Intel iwl3945 (0c:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)) and kernel 2.6.31-17-generic.
Here is the relevant section of /var/log/syslog: Dec 22 17:49:40 lappy586 wpa_supplicant[1238]: Failed to initiate AP scan.
