Windows Vista Wi-lan switch goes out after connecting to network

My switch keeps going out everytime right after it connects to a networkSometimes when i open a progam, my Wi-lan switch goes out with every program i open like internet explore or if I get luckyIt connects to my internet explore homepage but then as soon as i try to proceed going to a new address,it drops the signal that way as wellAnd even sometimes!with the slightest movement of my laptop cause the signal to drop and my Wi-lan switch seem to be trying to search for the signal again like i just turned the switch onall of this leads to my Wi-lan switch to disconnect from a perfectly good signal that my neighborhood shares and goes right back to acting like it need to search for the signal to reconnect again and then like after 5 times of disconnecting,it totally loses the connection to my neighborhood network and i have to end up restarting my pc just to get the signal that I always connect to backI don't know what i could have done for my acer aspire 3680 labtop pc to start acting this way it just started happening all of a sudden in 1day and have'nt been right since

 

Go to Device Manager, find the wireless adapter, right-click on it and select Properties. Under the Driver tab, select Roll Back Driver if you can select it.

If you have Driver Updates set to automatically install by Windows Update, disable it. Get your drivers from the Acer website. Check the Acer website for updated drivers for the wireless LAN adapter.
