If you're experiencing weak Wi-Fi signals and frequent disconnections on your Oppo A9 2020, you can try the following troubleshooting steps to address the issue:

1. Router placement and interference: Ensure that your Wi-Fi router is placed in an open area, away from obstructions such as walls or furniture that can weaken the signal. Additionally, other electronic devices operating on the same frequency, such as cordless phones or microwave ovens, can cause interference. Keep your phone away from such devices or try changing the Wi-Fi channel on your router to reduce interference.
2. 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 be weak. Try moving closer to the router to see if the connection improves.
3. Wi-Fi network settings: Check the Wi-Fi settings on your Oppo A9 2020. Ensure that the Wi-Fi connection is set to "Automatic" or select the appropriate network name (SSID). You can also try "forgetting" the network and reconnecting to it.
4. Network congestion: If multiple devices are connected to the same Wi-Fi network, it can lead to network congestion and impact your connection. Disconnect devices that are not in use or limit the number of connected devices to improve the connection.
5. Software updates: Keep your Oppo A9 2020 up to date with the latest software updates. Manufacturers often release updates that address known issues and improve device performance.
6. Wi-Fi sleep settings: Some devices have Wi-Fi sleep settings that can affect the connection. Ensure that your phone's Wi-Fi sleep settings are disabled or set appropriately, so the connection remains active even during periods of inactivity.
7. Reset network settings: Go to the Settings menu on your Oppo A9 2020 and locate the "Network & Internet" or "Wi-Fi" 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.

If the problem persists after trying these steps, it is possible that there may be a hardware issue with the Wi-Fi antenna or radio in your Oppo A9 2020. In such cases, it is recommended to contact Oppo customer support or visit an authorized service center for further assistance and potential repairs.
