I'm experiencing an Xfinity service outage as I type this. I don't have internet or TV.

I noticed on my iPhone 6s Plus and iPad Air 2 (both running 10.1.1), that they both show the wifi icon as full strength. My wife's iPhone and iPad 3 running 10.1.1 is the same.

I know for sure I don't have internet at this moment, so shouldn't my phone automatically switch to cellular and turn off the wifi? Shouldn't the iPad wifi icon stop showing?

I have to manually turn off wifi to get on LTE on my phone.

The wifi icon switching off used to happen with other iOS's when there wasn't wifi. Anyone experienced this? Thoughts?

This behavior is by design. The phone has no way to know your WiFi network has been islanded.

For certain things like iMessage it will give up and send over cellular after a timeout, but in general in this situation you should just turn off Wifi.

But you are still connected to the WiFi network. Even though there is no movement on the network, the SSID still exists. If your router was unplugged, the SSID would disappear and your iPhone would drop it. As long as the SSID is present, it will remain connected, even if the network itself is down.
