How can I troubleshoot the weak and unstable Wi-Fi connection on my Oppo R9s?

If you're experiencing weak and unstable Wi-Fi connection on your Oppo R9s, there are several troubleshooting steps you can try to improve the situation:

Oppo R9s

1. Restart your phone: A simple restart can often fix temporary glitches and connectivity issues. Turn off your Oppo R9s, wait for a few seconds, and then turn it back on.
2. Move closer to the Wi-Fi router: Weak signals can occur if you're far away from the router. Try moving closer to the router to see if the signal strength improves.
3. Check Wi-Fi signal strength: Open the Wi-Fi settings on your Oppo R9s and check the signal strength. If the signal is weak, it may be necessary to reposition the router or use a Wi-Fi range extender to boost the signal.
4. Forget and reconnect to the Wi-Fi network: Sometimes, there may be a problem with the saved network settings. Go to the Wi-Fi settings on your phone, find the network you're connected to, and select "Forget" or "Remove." Then reconnect to the network by selecting it from the available networks and entering the password.
5. Reset network settings: Resetting the network settings on your phone can help resolve connectivity issues. Go to the Settings menu, find the "System & Updates" or "System" section, and look for "Reset" or "Backup & Reset" options. Choose "Reset Network Settings" or a similar option, and confirm the reset. Note that this will remove all saved Wi-Fi networks and Bluetooth pairings, so you'll need to set them up again.
6. Update firmware and apps: Keeping your phone's firmware and apps up to date can often fix bugs and improve performance. Check for any available system updates or updates for specific apps by going to the Settings menu and looking for "Software Update" or "System Update" options.
7. Disable battery optimization: Some devices have aggressive battery optimization settings that can interfere with Wi-Fi connectivity. Go to the Battery settings on your Oppo R9s, find the app settings or battery optimization settings, and make sure that Wi-Fi and any relevant apps are not set to be optimized or restricted.
8. Test with different Wi-Fi networks: If possible, connect to a different Wi-Fi network, such as a public hotspot or a friend's network, to see if the issue persists. This will help determine if the problem is specific to your phone or the network you're trying to connect to.
9. Factory reset: If none of the above steps solve the problem, you can consider performing a factory reset as a last resort. This will erase all data on your phone, so make sure to back up your important files and contacts beforehand. To perform a factory reset, go to the Settings menu, find the "System & Updates" or "System" section, and look for "Reset" or "Backup & Reset" options. Choose "Factory data reset" or a similar option, and follow the prompts to reset your phone.

If you continue to experience Wi-Fi issues after trying these troubleshooting steps, it may be worth contacting Oppo support or your internet service provider for further assistance.
