There could be several reasons why your Oppo R11 may have a weak Wi-Fi signal and keep disconnecting. Here are some possible causes and solutions to resolve the issue:

1. Distance from the router: Make sure you are within a reasonable range of your Wi-Fi router. If you are too far away, the signal strength may weaken. Try moving closer to the router and see if the issue improves.
2. Obstacles and interference: Physical obstacles like walls, floors, and other electronic devices can interfere with Wi-Fi signals. Try moving your phone to a different location or repositioning your Wi-Fi router to minimize obstacles.
3. Router placement and settings: Ensure that your Wi-Fi router is placed in a central location and away from obstructions. Also, check the router settings for any issues. You can try resetting the router or updating its firmware if available.
4. Wi-Fi network congestion: If you are in a densely populated area or there are many Wi-Fi networks nearby, congestion can cause signal interference. Change your Wi-Fi channel to a less crowded one or switch to the 5 GHz frequency band if your router supports it.
5. Wi-Fi network settings on the phone: Check your phone's Wi-Fi settings. Disable any battery-saving modes or power-saving settings that might be affecting the Wi-Fi performance. You can also try "Forget Network" and reconnecting to the Wi-Fi network.
6. Software updates: Ensure that your Oppo R11 has the latest software updates installed. Manufacturers often release updates to address connectivity issues and improve overall performance.
7. Hardware issues: In some cases, the weak Wi-Fi signal and frequent disconnections could be due to a hardware problem with your phone's Wi-Fi antenna or other components. If none of the above steps resolve the issue, consider contacting Oppo customer support or taking your phone to a service center for further assistance.

Remember, the specific steps to resolve the issue may vary depending on your exact device model and software version. It's always a good idea to consult the user manual or check the manufacturer's support website for device-specific troubleshooting steps.
