The Xiaomi smartphone connected to Wi-Fi cannot access the Internet or frequently disconnects

If the Xiaomi smartphone connected to Wi-Fi cannot access the Internet or frequently disconnects, please refer to the following methods:
1. Please restart your phone, which can clear temporary glitches and refresh the network connections;
2. Try to forget and reconnect to the Wi-Fi network. Deleting and re-adding the network can resolve issues related to incorrect or outdated connection settings, allowing your phone to re-establish a fresh connection;
3. Check if the proxy settings are disabled. Proxies can sometimes interfere with internet access. Disabling them ensures that your phone connects directly to the internet without additional configuration;
4. Update your phone to the latest system version. Operating system updates can include bug fixes and improvements related to connectivity;
5. Update the router firmware. Router firmware updates can fix bugs and improve performance, addressing issues that will affect your phone’s ability to stay connected to the internet;
6. Disable or uninstall the third-party network optimization applications. These applications can conflict with your phone's native network settings;
7. Back up your phone and reset it to the factory settings.
If these methods do not resolve the issue, please contact the local after-sales service center for further assistance.
