1. Distance from the router: If your device is far away from the Wi-Fi router, the signal strength may be weak. Try moving closer to the router to see if the connection improves.
2. Interference from other devices: Other electronic devices, such as cordless phones, microwave ovens, or Bluetooth devices, can interfere with Wi-Fi signals. Make sure your phone is away from such devices, or try changing the Wi-Fi channel on your router to reduce interference.
3. Router issues: Restart your Wi-Fi router by turning it off and on again. Sometimes routers can encounter temporary glitches that can impact the connection.
4. Network congestion: If there are multiple devices connected to the same Wi-Fi network, it may result in network congestion and a poor connection. Disconnect devices that are not in use or limit the number of connected devices to see if it improves the connection.
5. Wi-Fi network settings: Check your Wi-Fi network settings on your phone. Ensure that the Wi-Fi connection is set to "Automatic" or the appropriate network name (SSID) is selected. You can also try "forgetting" the network and reconnecting to it.
6. Software or firmware issues: Ensure that your Xiaomi Redmi 9i is running the latest software updates. Manufacturers often release updates to address known bugs and improve device performance.
7. Wi-Fi signal strength: Install a Wi-Fi analyzer app from the Google Play Store to check the signal strength of your Wi-Fi network. If the signal is consistently weak, you might consider using a Wi-Fi extender or repositioning your router for better coverage.

If none of the above steps resolve the issue, it is possible that there may be a hardware problem with your phone's Wi-Fi antenna or radio. In such cases, it is advisable to contact Xiaomi customer support or take your device to an authorized service center for further assistance.
