Updated iOS not connecting to WiFi happens often to Apple users. If your device cannot connect to WiFi and you've lost contact with everything online, here is the right place for you to troubleshoot the issue.

Fix 1. Restart WiFi Router

If you are too far away from the router, it is difficult for your device to receive the signal and connect to the WiFi network. Therefore, make sure you are closer to it and within its range. If the WiFi not working issue still persists on iOS 18, it's time for you to perform a simple restart. Press the power button on the router to turn off it, wait for a while, and then turn it back on.
