1. Distance from the router: Ensure that you are within a reasonable range of your Wi-Fi router. If you are too far away, the Wi-Fi signal strength may be weak. Try moving closer to the router and see if the connection improves.
2. Router placement and interference: The placement of your Wi-Fi router can affect the signal strength. Keep it in an open area, away from obstructions such as walls, furniture, or electronic devices that can interfere with the signal. Additionally, other 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.
3. Network congestion: If multiple devices are connected to the same Wi-Fi network, it can lead to network congestion and impact the connection. Disconnect devices that are not in use or limit the number of connected devices to improve the stability of the Wi-Fi signal.
4. Wi-Fi network settings: Check the Wi-Fi settings on your Oppo A52. 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.
5. Software updates: Keeping your Oppo A52 up to date with the latest software updates is important. Manufacturers often release updates that address known issues and improve Wi-Fi performance. Check for any available system updates and install them if necessary.
6. Reset network settings: Go to the Settings menu on your Oppo A52 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.
7. Wi-Fi signal strength: Install a Wi-Fi analyzer app from the Google Play Store to check the signal strength of your Wi-Fi network. If the signal is consistently weak, consider using a Wi-Fi extender or repositioning your router for better coverage.

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 A52. In such cases, it is recommended to contact Oppo customer support or visit an authorized service center for further assistance and potential repairs.
