** Tags removed: bios-outdated-a17
** Description changed:
- 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 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.
- 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.
+ Also it is not just suspend that affects the LED, disabling wifi from
+ network menu or 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.
+
+ Note: I am not sure if it was clear enough that when the led is set to
+ blinking there is no issue with it being off upon resume etc.
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"
