Comment 37 for bug 464559

@Everyone: pls make sure, very sure, your HW enables the Wifi chip/radio.
BIOS first, then check hardware buttons/sliders and finally (it's the case with IBM's and Lenovo's notebooks) the Fn/F5 or any other combo key your PC may have.
rfkill is very useful to understand which one is off (soft are the latter case, while hard are the former twos).
I apologize with Chase for my very basic error of not checking BIOS first: my notebook came with Wireless disabled from factory (which may be just a specific situation, since the machine was originally shipped as a console - sigh!)... but checking BIOS should be the very first thing to do!

@Chase: Thanks again for your support and time.
