Note: An SSID is a unique key which identifies a wireless LAN. Its
purpose is to stop other wireless equipment from accessing
your LAN — whether accidentally or intentionally. To
communicate, wireless devices must be configured with the
same SSID.
WPS Push Button
The WPS (Wi-Fi Protected Setup) feature (sometimes associated with
a physical or on-screen button on most WAPs) allows you to pair
your device and WAP without the need for entering a passcode. This
process is similar to Wi-Fi Direct pairing.
In this case, once the WPS feature is active on your WAP, your device
can then detect it and then immediately pair to it.
Note: WPS-capable routers appear in the Wi-Fi list of available
devices with the term (WPS available) below their name.
To pair your device using WPS:
1. Follow the WPS activation instructions specific to your Wireless
Access Point.
2. From the main Settings page, tap Connections tab
Changing Your Settings
