my XR says I have a wifi connection but I can not open any apps that need the internet. All apps say no internet connection. All other devices are working fine

1. Turn OFF any VPN services that you may be using on your iPhone. If you do not use VPN then ignore this one.
2. Unplug your Wi-FI Router for 40 seconds and then plug it back in to electrical power again. This will reset it. You will not lose any settings on it.
3. If none of the above work then open Settings ➔ WI-Fi ➔ Tap on the "i" next the name of your Wi-Fi Network that you are connected to and then set Private Address to OFF.

You can reset network settings and try again-

Open Settings ➔ General ➔ Reset ➔ Reset Network Settings : You will have to enter your Wi-Fi Network password(s) again once the network reset has been completed. You will not lose any data that currently exists on your iPhone.

You are welcome. Glad it all worked out for you.

My Mac book pro has wifi connection but says I have no internet connection. All other devices work just fine. Router and modem have been powered off and reset.
