wifi detection with Acer Aspire 5715Z

Hi all,
I have an acer 5715Z under vista and MTNL as a provider of Internet access tonight by turning your PC, not connect with wifi (no detection network to 50 cm - detected and running on another laptop). On acer enet-management: impossible to change WLAN disconnected and no wifi network detected - "Connected" is not highlighted, and impossible to change this mode. In Device Manager, NIC only ethernet, not wifi. I said that it worked before .
Thank you

Wifi card had to disable.
In Device Manager -> View -> check Show hidden devices
If your wireless network card appears, click the right-reactive you.

But it may also be a hardware failure!
