On my Toshiba laptop, Ubuntu does seem to be able to hard blocking/unblocking the wifi card.

I dual-boot with Windows 7 and usually I leave wifi on. However, yesterday I disabled wifi while using Windows and when I rebooted into Ubuntu, I couldn't unblock the wifi. I had to reboot into Windows to re-enable the wifi.

rfkill unblock all and rfkill block all do not work for the hardware switch. Fn + F8 toggles the soft block of the wifi, whereas on Windows it toggles the hardware switch.

This is the result of lspci | Network

04:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)

Is there a way to enable Ubuntu to hard block/unblock the wifi card?

It is a bug in udev

Hummm, Suspend -> resume for me it works

It also cured the fact my altgr key was not functioning

My guess is event listener is stacking events and there is a lock preventing the queue from depiling the events. Suspend -> resume seems to «unfreeze» the queue...

I had a lot of problems related to this one... I guess taking the action (like rfkill unblock all) might be necessary too...
