1. Distance from the Wi-Fi router: If you are too far away from the router, the signal strength may weaken. Try moving closer to the router and see if the connection improves.
2. Obstacles and Interference: Physical obstructions such as walls, floors, or large objects can interfere with Wi-Fi signals. Ensure that there are no physical barriers between your device and the router. Additionally, other electronic devices like cordless phones, microwave ovens, or Bluetooth devices can cause interference. Keep your phone away from such devices.
3. Router Placement and Settings: Check the placement of your router. It should be positioned in a central location to maximize coverage. Also, verify that the router settings are properly configured. You may try resetting the router or contacting your internet service provider for assistance.
4. Wi-Fi Channel Congestion: If there are many Wi-Fi networks in your area, there could be interference due to channel congestion. Use a Wi-Fi analyzer app to check for less crowded channels and manually switch your router to a less congested channel.
5. Software Issues: Ensure that your Xiaomi Redmi Note 3 Pro is running the latest software updates. Sometimes, outdated or buggy software can cause Wi-Fi connectivity problems. Check for any available system updates and install them.
6. Wi-Fi Sleep Policy: Some devices have a "Wi-Fi sleep policy" that can cause the connection to drop when the device is idle for a certain period. Go to the Wi-Fi settings on your phone and disable any sleep or power-saving policies that may be enabled.
7. Network Authentication Issues: Double-check that you have entered the correct Wi-Fi password on your device. If you're unsure, you can try forgetting the Wi-Fi network and then reconnecting, entering the password again.

If the above steps do not resolve the issue, it's possible that there may be a hardware problem with your phone's Wi-Fi antenna or chipset. In such cases, contacting Xiaomi support or visiting an authorized service center would be advisable to diagnose and resolve the problem.
