Precaution while using WiFi
Wi Fi Protected Setup
Wi Fi Protected Setup is an optional feature that simplifies and standardizes the process of configuring and securing a Wi Fi network. It configures the network name (SSID) and WPA2 security for the gateway and client devices on a network and makes adding a new device to your network as easy as pushing a button or entering a personal information number (PIN). Products certified for Wi Fi Protected Setup are available at major electronics retailers and display this identifier mark on their packaging.
