If you're working in a remote location where other un-trusted wireless networks or computers may be active and you don't plan to go online, it's a good idea to disable your wireless connection. Disabling your computer's wireless adapter prevents other networks and computers from accessing your computer. You can easily reactivate the wireless connection when you need it later.
Disabling the Wi-Fi connection
Follow these steps to disable the Wi-Fi (Wireless Fidelity) connection and prevent access to your computer:
1. Right-click the wireless connection icon in the Windows system tray.
2. Choose Disable from the context menu that appears. The connection is disconnected, and the wireless connection icon disappears from the system tray.
 | Right-clicking the wireless connection icon in the Windows system tray gives you access to several useful commands relating to the wireless connection. You can also use this context menu to quickly view a list of other available networks or to review the status of the connection. |
Reactivating the connection
Follow these steps when you're ready to reactivate the Wi-Fi connection:
1. Choose Start --> Connect To.
2. In the submenu that appears, choose your wireless connection. The connection is restored, and the wireless connection icon reappears in the Windows system tray.
| If you want to connect to a different network, choose Show All Connections from the Connect To menu. In the Network Connections window that appears, right-click the wireless connection and choose View Available Wireless Networks. You can then choose a different wireless network, if others are available. |
