How to Connect Your Windows 8 Tablet to a Wireless Network
Tap the Charms bar’s Settings icon. When the Settings pane appears, tap the Network icon.
The bottom of the Settings pane shows six icons. The icon in the top left represents networks. The Networks icon toggles between Available and Unavailable depending on whether you’re currently within range of a wireless network.
Available: When the icon says Available, you’re within range of a wireless network. Move to Step 3 to begin connecting.
Unavailable: When the icon says Unavailable, you’re out of range and out of luck. (Wi-Fi signals rarely reach more than 300 feet from their transmitter.) Try moving to a different location or ask somebody if there’s a Wi-Fi signal available. Then return to Step 1.
