iPhone 15 and iPad disconnects from wifi

If your iPhone 15 and iPad Air 2 are experiencing issues with disconnecting from Wi-Fi, you can try the following troubleshooting steps to resolve the problem:

1. Ensure that you are within a reasonable range of your Wi-Fi router and that the signal strength is strong. Weak signals can result in frequent disconnections.
2. Power cycle your Wi-Fi router by unplugging it for about 10 seconds and then plugging it back in. This can often resolve connectivity issues.
3. On your iPhone and iPad, go to Settings > Wi-Fi, find your Wi-Fi network, tap on it, and select "Forget This Network." Then, reconnect by entering the Wi-Fi password.
4. Other electronic devices or neighboring Wi-Fi networks can cause interference. Make sure your devices are not surrounded by devices that emit strong signals and try changing your Wi-Fi channel to avoid interference.
5. Wi-Fi Assist is a feature that automatically switches to cellular data when Wi-Fi connectivity is poor. While useful, it might contribute to disconnections. You can disable it in Settings > Cellular > Wi-Fi Assist.
6. Access your router settings and ensure that it is configured correctly. You may need to consult your router's user manual or contact your Internet Service Provider for assistance.
