I've just removed the freaking Windows 8 from my LG N460-P.G55P1 (which came with it) and installed Ubuntu 12.10 32bits... You see, The thing is that i discovered later that my laptop came with a problematic ethernet adaptor called Atheros AR8161. I've been throught this issue for a while, because my laptop even refused to detect wired connection. I searched a little and i came to find a package that solved the wired connection problem. But now the Network Manager simply don't show any sign of detecting a Wifi component.

I'm a begginer, so, after 3h searching and trying some stuff on it, i thing its time to ask for some help... Here some stuff that might help you guys:

Please check out this question for an immidiate solution. The device, RTL8723AE should be properly supported by the 3.8 kernel in 13.04. –  mikewhatever Feb 25 '13 at 20:42
