[Bug 1037718] Re: Intel wifi led is off after resuming from suspend
Cas, please post the following terminal output as previously requested:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
** 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"

Title:
Intel wifi led is off after resuming from suspend
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
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.
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"
