Lost WiFi icon connection after some unkown children change

[feelit]

OS= Win 7 64bits Home Premium (French)

Hi,

Until yesterday, everything worked fine, but I let my laptop to my children and ...

I lost Wifi Icon for another type of icon, I mean the small icon between volume and hour (see "Win7 network.jpg").
Usually, I could view all possible Wifi networks, now I see none, it says "no identified network card".

I tried to de-activate and re-activate the wireless connections, but without success.

"Win7 network 2.jpg" is what I see when I unplugged the LAN cable.

Thanks 4 helping

P.S. Restauration did not help.

Try performing a System Restore to the point before your kids made modifications to your network settings.

op said restauration did not help, im assuming this meant system restore.

maybe re installing the wifi drivers would help,
