Here are some steps you can try to troubleshoot and resolve the Wi-Fi and cellular network problems:

Troubleshooting Steps​

1. Restart Your iPhone:
   • Press and hold the side button and either volume button until the power off slider appears.
   • Drag the slider to turn off your iPhone. Wait a few seconds, then press and hold the side button again until the Apple logo appears.
2. Toggle Airplane Mode:
   • Go to Settings or open Control Center and toggle Airplane Mode on. Wait a few seconds, then toggle it off. This can reset your network connections.
3. Forget Wi-Fi Network and Reconnect:
   • Go to Settings > Wi-Fi.
   • Tap the i icon next to your Wi-Fi network and select Forget This Network.
   • Reconnect to your Wi-Fi network by selecting it from the list and entering the password.
4. Reset Network Settings:

5. Check for Carrier Settings Update:
   • Go to Settings > General > About. If there's an update available, you should see a prompt to update your carrier settings.
6. Check Wi-Fi and Cellular Settings:
   • Ensure that Wi-Fi is turned on: Settings > Wi-Fi.
   • Ensure that Cellular Data is turned on: Settings > Cellular and make sure Cellular Data is enabled.
7. Disable Wi-Fi Assist:
   • Sometimes Wi-Fi Assist can cause issues with Wi-Fi connectivity.
   • Go to Settings > Cellular and scroll down to Wi-Fi Assist and turn it off.
8. Update iOS Software:
   • Check for any additional software updates.
   • Go to Settings > General > Software Update to ensure your iPhone is running the latest version of iOS.

Advanced Steps​

1. Restore iPhone via iTunes or Finder:
   • Back up your iPhone using iCloud or iTunes/Finder on a computer.
