What is WiFi Assist?
This feature is a convenient option for those who do not want to input usernames and passwords repeatedly or continually switch between Wi-Fi networks. It also allows you to see all available wireless networks on your device as opposed to just a list of saved WiFi networks. The option is turned on by default. To turn on WiFi Assist, follow the steps below:
Go to Settings>Wi-Fi. Tap on the blue (i) icon next to your Wi-Fi network. Scroll down and tap on “Advanced”. Check the box next to “WiFi Assist”.
Now that you’ve turned WiFi Assist on, you can still manually choose a Wi-Fi network or hotspot. But it will automatically connect to the network that you choose. This is convenient for those with limited data plans, as the feature will switch to cellular data once the Wi-Fi connection is weak, thus saving your data.
