Have you tried to use the OEM's drivers first? Please check with them first in order to obtain the latest drivers as their drivers are made customized and made specifically for the type of system you have if this wireless adapter is native to this system. Here you can find their contact information: Computer Manufacturer Support Websites
Alternatively, you can use our generic drivers if the issue still persists after you tried the OEM version.
In this situation, it is advised to remove all WiDi related components then install the current recommended versions.
