Go to Device Manager and find out what your Wifi card is (under networking).
if it is Intel xxxx or Intel Centrino xxxx goto
https://downloadcenter.intel.com and download fresh intel drivers.
If this doesn't resolve your problem, you need to get a USB WiFi card as a replacement and right click your build in WiFi card in device manager and select disable.
