iPhones Are Experiencing Wi-Fi Issues
Ever since iOS 17 became available to the public, some users have been reporting problems with their Wi-Fi connection.
Even if you’re at home and have a solid internet connection, your iPhone might not be able to connect to your network properly.
In many cases, this seems to also affect your data connection; even if you use mobile data, your iPhone might still have a hard time getting online.
Fortunately, most people have managed to solve this issue by restarting their iPhones. You can do the same simply by long-pressing the Side button on your iPhone and turning it off.
Likewise, you can also fix problems with your data plan by restarting your network settings. You do this by going to Settings > General > Transfer or Reset iPhone and then selecting Reset and Reset Network Settings.
