I have the same problem when I put my laptop in sleep an then wake it up again. 
Sometimes I manage to restore the wifi led by running 
sudo service udev --full-restart
sudo service network-manager --full-restart
sudo iwlist wlan0 scan


I am running Ubuntu 10.04 with 2.6.32-25 kernel. My laptop is an  Acer 1410. 
This is what I get from lsusb for my WiFi controller
 02:00.0 Network controller: Intel Corporation WiFi Link 1000 Series
