Next, re-enter the correct password to set up the connection. Finally, check again whether you can successfully connect to WiFi. I hope the above methods can help you solve WiFi connection problems.

Then select [Reset Network Settings], and finally confirm and click "Reset Network Settings" to complete the operation. Doing this can help resolve some network connection issues or restore network settings to their default state. Remember to back up important data before operation!

3. Force restart
If other devices can connect to WiFi normally and use data traffic, it is recommended to try restarting or force restarting your iPhone. This may help resolve WiFi connection issues.
The iPhone may encounter some glitches, resulting in the inability to connect to WiFi or frequent disconnections. However, generally speaking, the problem can be solved by simply restarting the iPhone and the WiFi connection can return to normal.
For iPhone 8 and later full-screen models, when you encounter a situation where you need to force restart, you can follow the following steps: First, quickly press the volume up button, and then quickly press the volume down button. Then continue to hold the power button until the iPhone screen is completely black and the Apple logo appears. At this point, you can release all the buttons and wait for the iPhone to restart automatically. By doing this, you can solve some possible problems and make your iPhone restart.

4. Restore factory settings
If your iOS system fails to connect to the Internet and is disconnected frequently due to updates, it is very likely that the system itself is faulty. To solve this problem, you can try factory reset. This process will restore your device to its original factory state and clear all personal data and settings. Make sure to back up your important data in advance, then follow these steps: 1. Open the Settings app and tap General. 2. Scroll to the bottom of the page and click "About This Mac." 3. On the About This Mac page, find and click the "Reset" option. 4. On the reset page, select "All content & settings." 5. The system will ask you to enter the device password or Apple ID password for confirmation. 6. Finally, click "Erase iPhone" or "Erase iPad" to start the factory reset process. Please note that after a factory reset, your device will reboot and require re-setup and configuration. Hope this method can help you solve the networking problem and restore normal use.
Open iPhone settings and click on General options. In the general options, find the option to transfer or restore iPhone and click to enter. Among the options to transfer or restore iPhone, select Erase all content and settings. Follow the prompts to complete the operation of resetting your iPhone, and the reset will be completed. This will clear all data and settings and restore the iPhone to its factory settings.

Restore factory settings refers to the operation of restoring iPhone to the original purchase state. In addition to hardware failures, other problems can generally be solved. However, it should be noted that restoring factory settings will clear all data on the device, so you need to back up relevant data in advance before operating.
You can easily selectively back up & restore iPhone data with the help of Apple's data management tools.

5. iOS system repair
After upgrading/downgrading the iOS system, jailbreaking, etc., the iPhone may experience WiFi failure or network disconnection. It is recommended to repair the iOS system.
You can try using the Apple phone repair tool. The standard repair mode will not clear device data. This tool supports the easy repair of 150 iOS devices such as white apples, black screens, constant restarts, failed updates, and inability to boot.

6. Update the latest version of iOS16
We know that even the official version of iOS16 has been updating the iOS system to fix various bugs. For example, the latest release of iOS 16.0.2 provides multiple bug fixes and important security updates.
Therefore, if it is not a hardware failure, you can try to update the latest version of iOS16 to see if it can solve the problem of being unable to connect to WiFi, disconnection, etc.
7. Downgrading iOS16 to iOS15
If you encounter network problems after upgrading to iOS 16 that seriously affect your daily life and travel, I suggest you downgrade the system to iOS 15 first. This will restore a stable network connection and ensure your normal use.
Supports the iPhone repair tool for downgrading to iOS15.7. This tool can also handle iOS system failures that may occur during the downgrade process.
