I'm using Lenovo G580. when I turn WiFi/Bluetooth on with Fn+F5, it's actually not turning on. To turn it on, I need to restart. How can I solve this problem?

I have the same computer and I cannot reproduce this. If I hit Fn+F5 it turns it off, when I hit it again it turns it on again. Which version of Ubuntu are you using? –  don.joey Apr 3 at 6:30

You can turn the software switch back on by executing the following command in a terminal:
