I now understand your hardware info question...but I don't understand what you did.
The first thing to check is:
Code:
rfkill list all
This tells you if something is switched off.  For example,
Quote:
wadda@mini:~$ rfkill list all
0: phy0: Wireless LAN
	Soft blocked: yes
	Hard blocked: no
The wireless is turned off via a software switch.  If the 
Hard blocked was 
yes it would mean the switch on the laptop was has turned the wireless off. (On my machine it's 
<FN><F3> to toggle on/off.  Others have an actual push putton, or slider, switch)
If hard block is 'yes', flick the switch; If soft is 'yes'
Code:
sudo rfkill unblock wifi
...give that a go.
