Cas, please post the following terminal output as previously requested:

** Description changed:
- I have set the wifi "options iwlegacy led_mode=1" in
/etc/modprobe.d/wlan.conf to stop the led blinking, which works as expected.
The problem I have found is that if I suspend the laptop then upon resuming the
wifi led is permanently off yet
- the wifi still works properly.
+ The problem I have found is that if I suspend the laptop then upon
+ resuming the wifi led is permanently off yet the wifi still works
+ properly. Also it is not just suspend that affects the LED, using the
+ hardware wifi switch on the laptop results it the same problem that the
+ LED is permanently off after turning wifi back on. This is regression
+ going from kernel 2.6.38 (Natty) to 3.0 onwards.
- I noticed the same occuring in Precise but I think it was working in
- Oneiric.
+ WORKAROUND: I have set the wifi "options iwlegacy led_mode=1" in
+ /etc/modprobe.d/wlan.conf to stop the led blinking, which works as
+ expected.
+
+ WORKAROUND: To get the LED back on without rebooting reload the module:
+ rmmod iwl3945 && modprobe iwl3945
+
+ WORKAROUND: For the suspend issue is to add to /etc/pm/config.d/modules :
+ SUSPEND_MODULES="iwl3945"
