Scroll down to Wireless Zero Configuration, and tell me if that service is started or not.
In your system tray right click the Wireless Network Connection icon. Then select "Status". Then, in the window that opens, click on "Properties". Then click on the "Wireless Connections" tab. Then check the box at the top that says "Use windows to manage my wireless connections".
Does your printer and sound work still? Don't reinstall the adapter driver. We might need to create a network later.
