Since this is a kernel issue the BIOS update is irrelevant to this issue but I did it anyway and the issue persists.
I just now reported it upstream to wireless mailing list so will see what happens there. ** Tags removed: bios-outdated-a17 ** Tags removed: quantal ** Tags added: saucy ** Tags added: quantal ** Changed in: linux (Ubuntu) Status: Incomplete => Triaged -- 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.
