Sure! I know about this, but my point majority of people do not even know about it! Or had no idea that their security setting has been set back to open broadcast itself. You can't see it happen! With wires you can easily noticed if somebody messed up with your cables.
And finally these WPA2 STILL not 100% secured anyway! I have one of my friend who knows how, and he laughed when one thinks it is fool-proof.
