If you're experiencing a weak and unstable Wi-Fi connection on your Oppo R11 Plus, here are some steps you can take to improve the situation:

1. Restart your device: A simple restart can sometimes resolve temporary glitches or conflicts that may be affecting the Wi-Fi connection. Turn off your Oppo R11 Plus and then turn it back on after a few seconds.
2. Move closer to the router: Ensure that you are within a reasonable range of your Wi-Fi router. If you're too far away, the signal strength can weaken, resulting in a weak connection. Moving closer to the router can help improve the Wi-Fi signal.
3. Check for obstructions and interference: Physical objects such as walls, furniture, and other electronic devices can obstruct the Wi-Fi signal. Try to minimize the number of obstructions between your device and the router. Additionally, other electronic devices operating on the same frequency, such as cordless phones or microwave ovens, can cause interference. Keep your Oppo R11 Plus away from such devices.
4. Forget and reconnect to the Wi-Fi network: Sometimes, the connection profile for a Wi-Fi network can become corrupted, leading to connection issues. To resolve this, go to the Wi-Fi settings on your Oppo R11 Plus, locate the Wi-Fi network causing the problem, and tap on "Forget" or "Forget network." Then, reconnect to the network by selecting it from the available Wi-Fi networks and entering the password if required.
5. Reset network settings: Resetting the network settings on your Oppo R11 Plus can help resolve Wi-Fi connection issues. Go to the Settings app, find the "Additional settings" or "System" section, and look for "Backup & reset" or "Reset options." Tap on it and select "Reset Wi-Fi, mobile & Bluetooth" or a similar option. Note that this will reset all network-related settings, including Wi-Fi, mobile data, and Bluetooth settings.
6. Update software: Make sure your Oppo R11 Plus has the latest software updates installed. Software updates often include bug fixes and improvements, which can address Wi-Fi connectivity issues. Check for updates in the Settings app under "Software Updates" or "System Updates."
7. Safe mode and third-party apps: Booting your device into safe mode can help determine if a third-party app is causing Wi-Fi connection problems. In safe mode, only pre-installed system apps will be available, and third-party apps will be temporarily disabled. If the Wi-Fi connection improves in safe mode, it suggests that one or more of your installed apps may be causing the issue. Uninstall recently installed or suspicious apps to see if that resolves the problem.
8. Factory reset: If all else fails, performing a factory reset can help resolve persistent Wi-Fi connection issues. Make sure to back up your important data before proceeding, as a factory reset will erase all data on your device. You can find the factory reset option in the Settings app under "Additional settings" or "System" and then "Backup & reset" or "Reset options."

If the problem persists even after trying these steps, it may be helpful to contact Oppo support for further assistance or visit an authorized service center. They can provide additional troubleshooting steps or evaluate if there's a hardware issue with your Oppo R11 Plus that needs to be addressed.
