Perhaps the killswitch was pressed accidentally?
Fn + F2 is the wifi killswitch in Fedora, so might be the same for Ubuntu guys as well
Check: /var/log/messages for any errors reported on the card, you can also reload the module to see if anything gets spit out in /var/log/messages as well:
# rmmod ipw3945
# modprobe ipw3945
and open a seperate window and run a: tail -100f /var/log/messages to see if anything spits out when the module is unloaded and reloaded...otherwise try the killswitch, by pressing Fn+F2 once, then wait a second and see if messages reports the kill and then Fn+F2 to bring it back online.

The WLAN LED does not glow on recent Intel-based notebooks (including Sony Vaio, Dell Inspiron, Lenovo Thinkpad and many others - we know, please don't list yours here), using the iwl4965 or iwl3945 WiFi drivers.
This problem is fixed for Ubuntu 8.04 (Hardy) in the backported kernel modules. (Note, however, that it does not behave the same way as it used to. The light will not blink on and off, but will be steady.)
Please install 'linux-backports-modules-hardy':
:~$ sudo apt-get install linux-backports-modules-hardy
then:
:~$ sudo rmmod iwl3945; sudo modprobe iwl3945
This Fixed my Wifi LED Problem!
