The GA1000 has a single red status LED:
During scanning (see wln.scan*), the LED blinks.
When the GA1000 is associated with an access point (see wln.associate*), the LED is ON.
When the GA1000 is in ad-hoc mode and has another peer connected to it, the LED is ON as well.
In all other cases, the LED is off.
