Why is the Wi-Fi connection on my Oppo R9 weak and keeps dropping and how can I fix it?

The weak Wi-Fi connection and frequent dropping on your Oppo R9 could be caused by several factors. Here are some possible reasons and steps you can take to address them:

1. Distance from the router: Ensure that your Oppo R9 is within a reasonable range of your Wi-Fi router. If you are too far away, the Wi-Fi signal strength may be weak. Move closer to the router and see if the connection improves.
2. Wi-Fi signal interference: Wi-Fi signals can be affected by physical obstacles and interference from other electronic devices. Make sure there are no obstructions like walls or large objects blocking the Wi-Fi signal between your phone and the router. Additionally, keep your phone away from other devices that can cause signal interference, such as cordless phones, microwaves, or Bluetooth devices.
3. Router issues: Check if the problem is specific to your Oppo R9 or if other devices also experience Wi-Fi connection drops. If multiple devices are affected, the issue may be with your router. Try restarting your router and see if it improves the Wi-Fi connection stability.
4. Wi-Fi network settings: Check the Wi-Fi settings on your Oppo R9. Make sure you are connected to the correct Wi-Fi network and that the connection settings are configured properly. You can try "forgetting" the Wi-Fi network and reconnecting to it to establish a fresh connection.
5. Software updates: Ensure that your Oppo R9 is running the latest software updates. Manufacturers often release updates to address known issues and improve device performance, including Wi-Fi connectivity. Check for any available system updates and install them if necessary.
6. Reset network settings: Go to the Settings menu on your Oppo R9 and find the "Wi-Fi & Internet" or "Network & Internet" section. Look for an option to reset network settings or reset Wi-Fi settings. This will clear any saved Wi-Fi networks and their associated settings. Afterward, you can reconnect to your Wi-Fi network and check if the issue is resolved.
7. Battery optimization settings: Some Oppo devices have aggressive battery optimization settings that may affect Wi-Fi performance. Go to the Settings menu, find the "Battery" or "Battery & Power" section, and look for any battery optimization settings related to Wi-Fi or network connectivity. Disable or adjust these settings if necessary.

If the problem persists, it is recommended to contact Oppo customer support or visit an authorized service center for further assistance. They may be able to provide specific troubleshooting steps or advice tailored to your device and address any potential hardware issues.
