Why can't Apple connect to wifi (I can't connect to WiFi after upgrading iOS 16)?

IOS 16 has added many practical functions, and iPhone users have started to update and upgrade. However, after upgrading to iOS 16 system, some users are inexplicably disconnected from the network, while other devices can connect to the network normally.

After updating iOS 16, iPhone can't connect to WiFi, or it is inexplicably disconnected when it shows that it is connected to the Internet (WiFi/5G/4G). It's useless to turn on and off the flight mode. What should I do?

I collected and sorted out 7 repair techniques for iPhone that can't connect to WiFi or often disconnect from the Internet, and chose the corresponding solutions according to possible reasons!

1, forget the network

IPhone can't connect to WiFi. You can ignore this network setting and re-enter the password connection setting after disconnecting WiFi. Check again to see if you can connect to WiFi normally.

2. Reset the network

If the network connection doesn't work, resetting network settings is another effective solution.

Click iPhone Settings-General-Transfer or Restore iPhone, click Restore-Restore Network Settings, and click Reset Network Settings to confirm.

3. Forced restart

When other devices can connect to WiFi normally, they can also use data traffic normally. It is recommended to restart or force the iPhone to restart.

IPhone may be unable to connect to WiFi due to some glitches in the iOS system, or the network is frequently disconnected. Generally, the connection can be restored after restarting the iPhone.

Full-screen models (iPhone8 and above) forced restart operation: press the high and low volume keys quickly, then press the power button continuously until the Apple logo appears after the iPhone is black, and release the button to wait for the iPhone to restart.

4. Restore factory settings

Due to the update of iOS system, networking failed, and the network was often disconnected. There is a high probability that the iOS system has failed, and you can try to restore the factory settings.

Click iPhone Settings-General-Transfer or Restore iPhone, click Erase all contents and settings, and follow the prompts to complete the operation of resetting iPhone.

Restoring the factory settings is to restore the iPhone to the state when it was just bought. Non-hardware faults can generally be solved, but all data of the equipment will be cleared. Relevant data needs to be backed up in advance. You can choose to use Niu Xuechang's Apple data management tool to back up iPhone data.
