How can I resolve the issue of weak and intermittent Wi-Fi connection on my Oppo A91?

How to Fix Weak and Intermittent Wi-Fi Connection on Oppo A91

1. Check Wi-Fi Signal Strength

Make sure you are within range of your Wi-Fi router and check if other devices have a good signal in the same area. Weak signal strength can result in a poor connection.

2. Restart the Router

Restarting your Wi-Fi router can often solve connectivity issues. Simply unplug the power cord, wait for a few seconds, and then plug it back in. After the router restarts, try connecting to Wi-Fi again.

3. Adjust Router Placement

Place your Wi-Fi router in a central location, away from obstructions such as walls or electronic devices that can interfere with the Wi-Fi signal. Positioning the router at a higher point can also improve coverage.

4. Forget and Reconnect to Wi-Fi Network

On your Oppo A91, go to Settings > Wi-Fi, tap on the network you are having issues with, and select "Forget." Then, reconnect to the Wi-Fi network by entering the password again.

5. Reset Network Settings

If the issue persists, you can try resetting your network settings. Go to Settings > System > Reset > Reset Wi-Fi, Mobile & Bluetooth. Confirm the reset and your network settings will be restored to default.

6. Update Software

Keeping your Oppo A91's software up to date is crucial for optimal performance. Check for any available software updates by going to Settings > Software Update and install them if available. This may include Wi-Fi connectivity improvements.

7. Disable Power Saving Mode

Power saving mode can limit the performance of your Wi-Fi connection to conserve battery. Ensure that your Oppo A91 is not in power saving mode while using Wi-Fi. Go to Settings > Battery > Power Saving Mode and disable it, if enabled.

8. Try a Different Wi-Fi Channel

There might be interference from other nearby Wi-Fi networks using the same channel. Access your router’s settings through a web browser, change the Wi-Fi channel to a less congested one, and reconnect your Oppo A91 to the network.

9. Factory Reset

If all else fails, you can perform a factory reset on your Oppo A91. Make sure to back up your data as a factory reset will erase all data and settings. Go to Settings > System > Reset > Factory Reset and follow the instructions to reset your device.

By following these steps, you should be able to resolve the issue of weak and intermittent Wi-Fi connection on your Oppo A91 smartphone.
