How to Turn on a Wireless Adapter
Wireless network adapters are found mainly on laptops, but desktop computers also can have them. One of the most common problems regarding connectivity errors is a disabled wireless adapter. Laptops usually have a switch on the front that allows you to quickly enable the adapter. But the process with a desktop computer requires following several steps to turn on the wireless adapter.
Choose the "Control Panel" option in the pop-up menu.
In Windows Vista, click on "Device Manager." Click the "+" sign next to Network Adapters and right-click on the wireless adapter. Click "Enable."
In Windows 7, click "Network and Sharing," then "Network Options." Click "Manage Network Connections." Right-click on the wireless adapter and enable it by choosing the "Enable" option.
In Windows XP, click "Performance and Maintenance," then the "System" icon. Choose the "Hardware" tab, then "Device Manager." From here, right-click on the wireless adapter and click "Enable."
