Comment 25 for bug 464559

@Truxpin:

A relative of mine recently bought a Lenovo Y450. Even under windows, we couldn't get wireless to work out of the box as it came from the factory (amazing engineering there...). We finally found out through a google search that there are two rf switches (I cannot fathom why they thought this was a good idea) on the laptop: a normal "switch" and a keyboard function key. My guess is that you have flipped the normal "switch", but maybe you need to hit the function key on the laptop.

As an example, I found an image of the Y450 keyboard (I couldn't find an image of your keyboard): http://www.thinkpads.com/wp-content/uploads/2009/05/lenovo_ideapad_y450_keyboard.jpg. Notice that it has a wifi symbol on the F5 key. By hitting Fn+F5 you turn on and off wireless. You have to have the wireless enabled through this key combo AND the "switch" for wireless to work.

Please look for any similar switches on your laptop to see if you can enable it.
