There could be several reasons why your Samsung Galaxy M04 is experiencing a weak and intermittent Wi-Fi connection. Here are some possible causes:

1. Signal Interference: Wi-Fi signals can be disrupted by other electronic devices, walls, and physical obstacles. Make sure there are no large objects or walls obstructing the signal between your phone and the Wi-Fi router. Additionally, try moving closer to the router to see if the signal strength improves.
2. Distance from the Router: If you are far away from the Wi-Fi router, the signal may weaken. Wi-Fi signals have limited range, so try moving closer to the router and see if the connection improves.
3. Router Issues: The problem may lie with the Wi-Fi router itself. Try restarting the router by unplugging it from the power source, waiting for a few seconds, and plugging it back in. This can often resolve temporary glitches or issues with the router.
4. Wi-Fi Network Congestion: If you are in a densely populated area or an area with many Wi-Fi networks, there may be congestion that affects your connection. In such cases, try changing the Wi-Fi channel on your router to a less crowded one.
5. Software or Firmware Issues: Ensure that your Samsung Galaxy M04 has the latest software updates installed. Manufacturers often release updates that include bug fixes and improvements, including those related to Wi-Fi connectivity.
6. Wi-Fi Sleep Policy: Check your phone's Wi-Fi sleep policy settings. If it is set to turn off Wi-Fi when the device is idle, it may cause intermittent connectivity. Adjust the settings to keep Wi-Fi active even when the phone is not in use.
7. Network Authentication Issues: Ensure that you are using the correct Wi-Fi password and authentication method. Incorrect credentials can prevent your phone from connecting to the network or result in a weak connection.

If none of the above steps resolve the issue, it's possible that there may be a hardware problem with your phone's Wi-Fi antenna or other components. In such cases, contacting Samsung support or visiting a service center would be advisable for further assistance and troubleshooting.
