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
3. Press
4. Once the connection is complete, confirm the external router
now appears in the Wi-Fi list as connected.
WPS PIN Entry
If a WPS Push Button does not work, there is an alternative WPS
connection method where you would use a device generated PIN
number to establish the connection. This number is then entered into
your WAP's WPS client PIN field to complete the connection.
To pair your device using WPS PIN:
1. From the main Settings page, tap Connections tab
2. Press
