But I don't know why iwconfig indicates that it is not associated.
Could also be a bug in the kernel module for your wireless device. It is not uncommon to see funny driver errors after suspend/resume. It looks like wpa_supplicant and associated code is doing what it is supposed to be doing. Timeout value of your dhcp client is controlled elsewhere such as /etc/dhcp3/dhclient.conf for dhcp3-client.
