Thank you for your post, sorry to hear that you are experiencing quite some trouble after the driver update.
If you haven’t already, try downloading the latest drivers that the Asus* has available, save them then go ahead and uninstall the software and drivers currently installed:
Note: Do not restart your computer until you followed all the steps bellow. This will clean all profiles from your system and network passwords will need to be re-entered.
1- Remove the Intel® PROSet software from Control Panel\uninstall Programs if present, and select not to save any Profiles or user data.
2- Go to Start right-click on computer\click on properties\then on the top left click device manager\ ”Network Adapters”\Double-Click the adapter name\Drivers Tab and click on the “Uninstall Drivers” button.
3- Install the drivers you downloaded earlier from Asus.
Something good to know is that wireless adapters are customized for each computer. (This to make sure that they are and stay compliant with FCC and IEEE regulations) this is why we only offer generic drivers.
