1. Distance from the router: Make sure you are within a reasonable range of your Wi-Fi router. Walls and other obstructions can weaken the signal strength. Try moving closer to the router to see if it improves the signal quality.
2. Interference: Check if there are any other electronic devices in the vicinity that may be causing interference, such as cordless phones, microwave ovens, or other Wi-Fi networks. Move away from these devices or change the Wi-Fi channel on your router to avoid interference.
3. Wi-Fi router issues: Restart your Wi-Fi router to refresh its settings. Sometimes routers can experience issues that affect connectivity. Additionally, check if there are any firmware updates available for your router and install them if necessary.
4. Wi-Fi settings on your phone: Verify that your phone's Wi-Fi settings are configured correctly. Go to the Wi-Fi settings menu and ensure that you are connected to the correct network. You can also try forgetting the Wi-Fi network and reconnecting to it.
5. Software updates: Ensure that your Xiaomi Redmi 9T is running the latest software updates. Manufacturers often release updates to address known issues and improve overall device performance.
6. Reset network settings: If none of the above steps help, you can try resetting the network settings on your phone. This will erase saved Wi-Fi networks and their passwords, so make sure to have them handy. To reset network settings, go to Settings > System & Device > Reset > Reset Wi-Fi, mobile & Bluetooth.

If the problem persists after trying these steps, it may be worth contacting Xiaomi support or your internet service provider for further assistance. They may be able to provide specific troubleshooting steps or determine if there is a hardware issue with your phone.
