Install iOS 10.2.1 If You Use Ethernet Connectivity
If you pair ethernet connectivity with your iOS devices, you'll definitely want to think about installing the iOS 10.2.1 update today.
iOS has long supported ethernet connectivity but until recently, it didn't have a user interface to help manage ethernet connections. That's changed thanks to a recent version of iOS 10.
Apple's iOS 10.2 update delivered a new ethernet settings panel that allows iOS users to easily manage your ethernet connections.
Thing is, iOS 10.2 isn't available anymore. So, if you're on something older than iOS 10.2, you'll need to install iOS 10.2 to get the UI.
After you connect your device to ethernet you'll notice the new ethernet pane sandwiched between Wi-Fi and Bluetooth in settings.
