That sounds pretty weird...like it cant talk to wlan0 on the AP.
Run "ifconfig" on the AP and make sure wlan0 shows up. If it does, possibly the card in the laptop is bung? What if you double click on the icon in the system tray for the WLAN connection, can you see a list of SSIDs?
Is the WLAN connection in the lappie known to be good?
BTW you might get more people seeing the question if you post to the mailing list as well, I dont know how many ppl check the forums regularly
