If you're experiencing a weak Wi-Fi signal and frequent disconnections on your Oppo A5s, you can try the following troubleshooting steps to resolve the issue:

1. Check Wi-Fi signal strength: Ensure that you are within a reasonable range of your Wi-Fi router. Wi-Fi signals become weaker as you move farther away. Try connecting when you are closer to the router to see if the signal improves.
2. Restart your devices: Power off your Oppo A5s and your Wi-Fi router. Wait for a few seconds, then power them back on. This can help refresh the network connection and resolve temporary issues.
3. Reset network settings: Resetting the network settings on your Oppo A5s can often resolve connectivity issues. Go to Settings > Additional settings > Backup & reset > Network settings reset. Keep in mind that this will remove saved Wi-Fi networks, Bluetooth pairings, and other network-related settings. You'll need to reconnect to Wi-Fi networks and reconfigure other network settings.
4. Forget and reconnect to the Wi-Fi network: In the Wi-Fi settings on your Oppo A5s, forget the problematic Wi-Fi network and then reconnect to it. This can establish a fresh connection and resolve any temporary issues.
5. Change Wi-Fi channel: In crowded areas with many Wi-Fi networks, there may be interference or congestion that affects your connectivity. Access your router's settings and try changing the Wi-Fi channel to a less crowded one.
6. Update firmware: Ensure that your Oppo A5s is running the latest firmware updates. Software updates often include bug fixes and improvements that can enhance Wi-Fi performance. Check for updates in your device's settings or through Oppo's software update feature.
7. Disable Wi-Fi power saving mode: Some devices have power-saving features that can affect Wi-Fi performance. Go to Settings > Wi-Fi > Advanced Settings (or similar) and make sure that any power-saving mode or similar features are disabled.
8. Contact Oppo support: If the issue persists, it's recommended to contact Oppo's customer support or visit an authorized service center for further assistance. They can provide specific guidance and, if necessary, diagnose any potential hardware or software issues related to Wi-Fi connectivity on your device.

Please note that these steps are general suggestions, and the exact steps or options may vary depending on the specific software version and configuration of your Oppo A5s. It's always a good idea to refer to the user manual or consult Oppo's support resources for more specific guidance.
