I narrowed this down to working in kernel 2.6.38 (Natty) but stopped working in 3.0 onwards.
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. The only way to get the LED back on without rebooting is to reload the module: `rmmod iwl3945 && modprobe iwl3945` Thus a workaround for the suspend issue is to add SUSPEND_MODULES="iwl3945" to /etc/pm/config.d/modules -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1037718 Title: Intel wifi led is off after resuming from suspend Status in “linux” package in Ubuntu: Triaged Bug description: 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. I noticed the same occuring in Precise but I think it was working in Oneiric.
