WiFi is not working in windows 8

WiFi is not working in windows 8
I came across this problem when I upgraded in to windows 8. My laptop was Acer V3-571 G which bought in December 2012. There is no Wi-Fi button appear only the LAN icon was displayed. When I googled out and made it working.
My laptop contains the network adaptor is Qualcomm Atheros AR5BWB222 Wireless Network Adapter.

1. Go to device manager - > Control Panel\Hardware and Sound\Device Manager Or type Device Manager in the search box. 

Image for illustrative purpose only, not original.

2. If the Network adapter-> Qualcomm Atheros AR5BWB222 Wireless Network Adapter showing error then Uninstall the driver.
3.  I found the driver Qualcomm Atheros AR5BWB222 Wireless Network Adapter for my V3-571G under  "Windows 8 64-bit (upgrade from Windows 7)" from acer support site. Download the driver.(http://www.acer.com/worldwide/support/)
4. Install the downloaded driver and you can see the WiFi start working again.

The same steps will work in other computers manufactures too bu the you should ensure the exact driver software available or not.


Thanks!
