Turning on/off a wireless network connection
Most computers feature a ‘Wi-Fi’ button that turns the network
connection on or off. If your computer has wireless access, but does
not feature a Communication button, you may turn your wireless
network on or off, or control what is shared over the network with the
network management options. Press the Windows key ( ) + W, type
"HomeGroup" and then click on HomeGroup.
