What firmware is my wireless card is using?

After a fresh install of Lubuntu 12.04 on my Dell Latitude D600, I'm having wireless issues. It has an Intel PRO/Wireless BG2200 and is using the ipw2200 driver.

I've read that I may need to update the firmware, but before I go installing something new I would like to determine what's already there. How do I find this out?

Solution 1:

To find out the current firmware, just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:

sudo lshw -c network

once the command runs look for the firmware version, under the Wireless interface. See image below.
