When the phone is connected to Wi-Fi, if an exclamation mark appears on the Wi-Fi icon, it means there are some problems with the current connection. Here are some common causes and solutions:

1. Unable to connect to the Internet: If an exclamation mark appears on the Wi-Fi icon, it may be because your phone cannot connect to the Internet. This may be caused by a router outage, network failure, or a problem with your phone's settings. You can try the following solutions:

- Check the router: Make sure your router is working properly, you can try restarting the router to solve the problem.

- Check other devices: If other devices can connect to the same Wi-Fi network and access the Internet normally, then the problem may be caused by a problem with your phone's settings. You can try to reconnect to Wi-Fi or restart your phone to solve the problem.

- Check Wi-Fi password: Make sure the Wi-Fi password you enter is correct. If the password is wrong, your phone will not be able to connect to the Wi-Fi network.

2. Weak signal: If an exclamation mark appears on the Wi-Fi icon, it may be caused by a weak Wi-Fi signal. This may be due to reasons such as being too far from the router, blocking obstacles, or interfering with the signal. You can try the following solutions:

- Close to the router: Get as close to the router as possible to enhance Wi-Fi signal reception.

- Remove obstacles: Remove objects that may block Wi-Fi signals, such as walls, furniture, etc.

- Change channel: If there is interference from other Wi-Fi networks around you, you can try changing the Wi-Fi channel in the router settings to avoid interference.

3. Authentication issues: If an exclamation mark appears on the Wi-Fi icon, it may be caused by authentication issues. This may be because you entered the wrong Wi-Fi password or require additional authentication (such as entering a username and password) to connect to the Wi-Fi network. You can try the following solutions:

- Confirm Wi-Fi password: Make sure the Wi-Fi password you entered is correct. You can try re-entering your password to resolve the issue.

- Check network settings: If the Wi-Fi network requires additional authentication (such as entering a username and password), please make sure your phone is set up correctly and authenticate as required.

4. IP address conflict: If an exclamation mark appears on the Wi-Fi icon, it may be caused by an IP address conflict. This may be due to other devices using the same IP address on the network. You can try the following solutions:

- Reconnect Wi-Fi: You can try disconnecting and reconnecting to the Wi-Fi network to regain the IP address.

- Restart the router: Restarting the router may clear the IP address conflict and allow your phone to connect normally.

It should be noted that the reasons and solutions listed above are not all, and the specific situation may vary depending on factors such as network environment, device settings, and software version. If you encounter the problem of an exclamation mark appearing on the Wi-Fi icon, it is recommended that you check the above possible causes one by one and make adjustments and solutions according to the specific situation.
