To troubleshoot the小米 network failure,follow this organized approach:

1. Firewall Configuration:

   Ensure the router's firewall is configured to block port forwarding. Check the firewall settings to enable a specific port that prevents interference with other devices.

2. Device Wi-Fi Card:

   Verify that the smartphone's Wi-Fi card is recognized by the router. Check the device's settings to ensure it's using the correct Wi-Fi card.

3. Router Configuration:

   Enable firewall configurations to disable default Wi-Fi when a specific device is connected. Adjust the firewall settings to bypass the default network.

4. Router Internet Options:

   Disable the default Wi-Fi when a specific device (e.g.,小米) is connected. Look for settings in the router's configuration to disable this.

5. Router Internet Options - Wi-Fi Direct:

   Check if Wi-Fi Direct is enabled. If necessary, disable it to ensure compatibility with newer devices.

6. Router firmware:

   Ensure the router has the latest firmware version. Update the firmware if it's outdated, which can cause compatibility issues.

7. Wi-Fi Card Settings:

   Enable the correct Wi-Fi card on the smartphone. Check the device's settings to ensure it's using the intended card.

8. Password and Security:

   Use a strong password and ensure password recovery is enabled. Check the device's security settings to avoid compatibility issues.

9. Testing in Different Environments:

   Test the connection using an external Wi-Fi device to isolate the problem and confirm if the issue is with the router.

10. Error Messages and Settings:

    Review error messages from the router and device. Check for specific addresses or ports that are not responding.

11. Security Features:

    Ensure no security features (e.g., P2P) are causing interference. Check if these apps are properly configured and not causing issues.

12. System Configuration:

    Update the system to the latest software. This can prevent compatibility issues with newer devices.

By systematically addressing each of these areas, you can identify and resolve the root cause of your小米 network failure.
