I am using Lenovo - y470, which comes with windows 7 home premium. I can connect to my wifi network and there is no issue in that. But the problem comes if the network get disconnected and i again try to connect to same wifi network. As soon as i click on connect my system freezes, and i can not even press ctrl+ alt+ del . The only think i am allowed to do at that time is press and hold power button to shut down the system and restart it again.

Please tell me how to resolve this issue. Please let me know if some more information is required.

OS: Windows 7 Router: Netgear n-150

In general a freezing system would indicate either a hardware or a driver fault. So the first thing to do is update your wifi driver.
