How to Reset a Wireless Driver
Wireless adapters give you the ability to go online with your computer from anywhere there is an available Wi-Fi Internet connection. Like all pieces of computer hardware, however, these adapters are subject to occasional glitches such as conflicts with other devices and power interruptions. When this happens, the driver might need to be reset to a previously working version. Such tasks are simple with the use of the Device Manager in the Windows Control Panel.
Click the Start button and select "Control Panel." Click "System and Security," then "Device Manager."
Expand the "Network Adapters" category of your hardware list and double-click on your wireless adapter.
Click on the "Driver" tab and select "Update Driver." Select the option to select from a list or specific location, then click "Next."
Select the option to choose a driver to install and click "Next."
Select the matching driver from the list and click "Next." The wireless driver will be reset.
