What could be causing the Wi-Fi connection to be weak and unstable on my Samsung Galaxy M21s?

There are several factors that could be causing the Wi-Fi connection to be weak and unstable on your Samsung Galaxy M21s:

1. Distance from the Wi-Fi router: If you are too far away from the router, the signal strength may weaken, resulting in a weak and unstable connection.
2. Interference from other devices: Other electronic devices such as cordless phones, microwave ovens, and Bluetooth devices can interfere with Wi-Fi signals, affecting the stability of the connection.
3. Router placement: If the Wi-Fi router is placed in a corner or behind obstacles like walls, the signal may get blocked or weakened, causing instability in the connection.
4. Network congestion: If there are too many devices connected to the same Wi-Fi network, it can lead to congestion and result in a weak and unstable connection.
5. Outdated router firmware: If your router's firmware is not up to date, it may not be able to handle the latest Wi-Fi standards efficiently, causing issues with the connection.
6. Software or app conflicts: Certain software or apps on your Samsung Galaxy M21s may have compatibility issues with the Wi-Fi connection, leading to instability.

1. Move closer to the Wi-Fi router to ensure a stronger signal.
2. Minimize interference by keeping other electronic devices away from the router.
3. Reposition the router to a more central location in your home or office.
4. Limit the number of devices connected to the Wi-Fi network to reduce congestion.
5. Check for any available firmware updates for your Wi-Fi router and install them if necessary.
6. Try disabling or uninstalling any recently installed software or apps that might be causing conflicts.
