Toshiba NB505 - Wireless not working

[david.r...@gmail.com]

Hi, I recently installed android 4.4.4 from the android-x86 repository download:
http://sourceforge.net/projects/android-x86/files/Release%204.4/

But I am not able to connect to my wifi.
I´ve read I should use a live USB (I downloaded Lubuntu) and then once it loads, that I should copy the folder from /lib/firmware/ and then boot android and paste it on the same location on my hdd android install. But how do I access there? I get to log on directly over the android system.

Could anyone help me out?
I´ve also tried:

Could anyone please help me out? Thanks.
