I would like to confirm that I've been experiencing this same bug on my laptop with an Intel PRO/Wireless 5100 AGN controller.
After resuming from suspend, I would not be able to connect to a WPA2 network (WPA2-PSK).
When I unloaded and reloaded the wifi module, iwlagn, I was then able to connect to the wpa2 network.
This was the messages found in dmesg when failing to connect:
wlan0: authenticate with AP XX:XX:XX:XX:XX:XX
wlan0: authenticated
wlan0: associate with AP XX:XX:XX:XX:XX:XX
wlan0: RX AssocResp from XX:XX:XX:XX:XX:XX (capab=0x1 status=10 aid=0)
wlan0: AP denied association (code=10)
