How to Connect Your Windows 8 Tablet to a Wireless Network
Tap the Available icon, if it's present.
The Settings pane turns into the Network pane, listing the names of all the wireless networks around you. Depending on your location, you may see several listed. Windows ranks the wireless networks by signal strength, placing the strongest (and usually closest) network atop the list.
A wireless network's name is known as its SSID (Service Set IDentification). The SSID represents the name that you (or the network’s owner) chose when originally setting up the wireless network.
