I can join a Wi-Fi network but it will not connect to the internet

Hi tamatha261,

Thanks for contacting Apple Support Communities!

We understand that you can connect to a Wi-Fi network on your iPhone but you're unable to access the internet.

Is this happening with a specific Wi-Fi network or all Wi-Fi networks?

If it happens on all Wi-Fi networks, check out the troubleshooting steps outlined here to help isolate this behavior further: If your iPhone or iPad won't connect to a Wi-Fi network - Apple Support

"Check for issues with your Wi-Fi network

If iOS or iPadOS detects an issue with your Wi-Fi connection, you might see a Wi-Fi recommendation under the name of the Wi-Fi network that you're connected to. For example, you might see the alert "No Internet Connection." To get more information, tap the Wi-Fi network."

Take care!
