Thanks in advance for you help.

My gues is that it is .
Check out if your wifi card temperature is hot .
LAst time i did something like you did now , i also lost temporarly my alfa rtl 8187L card .
I had rx power , witch means that i could see wifi around , but i was unable to connect to them because i have losted the tx power .
The salvation to this specific card came 1 year later when i found a windows driver from alfa that enabled me to reprogram the card configuration again .
The name of the package was "RTL 8187l mass produtcion kit" , where i could change the default power of the card and also define a different mac address by default to that card to be stored in rom .

Anyway , try this on terminal :

iwconfig wlan0 scan

If you get results then it is the network manager , if you can not get results then it could be that your card eprom is messed out .
