Why does my Samsung Galaxy A21s keep losing Wi-Fi signal and how can I address this problem?

If your Samsung Galaxy A21s keeps losing Wi-Fi signal, there could be several reasons for this issue. Here are some possible causes and troubleshooting steps to address the problem:

Samsung Galaxy A21s

1. Distance from the Wi-Fi router: If you are far away from the router, the Wi-Fi signal may not reach your device properly, leading to intermittent connection drops. Try moving closer to the router and see if the issue improves.
2. Router Placement and Obstacles: The placement of your router and physical obstacles can interfere with the Wi-Fi signal. Ensure that the router is positioned in a central location and free from obstructions such as walls, furniture, or other electronic devices that may block the signal. Keep the router elevated for better coverage.
3. Wi-Fi Network Congestion: If multiple devices are connected to the same Wi-Fi network and using a large amount of bandwidth, it can cause congestion and result in a weaker connection or frequent disconnections. Consider disconnecting unnecessary devices or limiting their bandwidth usage.
4. Wi-Fi Network Settings: Check your Wi-Fi network settings on the Samsung Galaxy A21s. Make sure the network mode is set to the appropriate option (e.g., 2.4 GHz or 5 GHz) depending on your router's capabilities. Additionally, ensure that the network is not set to "metered," as this can affect Wi-Fi connectivity.
5. Wi-Fi Sleep Settings: Some devices have a feature called "Wi-Fi sleep" or "Keep Wi-Fi on during sleep." If this feature is enabled and set to a power-saving mode, it can cause the Wi-Fi connection to be turned off during sleep or when the screen is off. Go to Settings > Connections > Wi-Fi > Advanced > Keep Wi-Fi on during sleep and select "Always" or "Only when plugged in" to ensure a stable connection.
6. Software Updates: Ensure that your Samsung Galaxy A21s is running the latest software updates. Manufacturers often release updates to address known issues and improve device performance, including Wi-Fi connectivity. Check for any available updates in the phone's settings and install them if necessary.
7. Reset Network Settings: Resetting the network settings on your phone can help resolve Wi-Fi connectivity issues. Go to Settings > General Management > Reset > Reset Network Settings and confirm the reset. This will clear saved Wi-Fi networks, Bluetooth pairings, and other network settings. You'll need to reconnect to your Wi-Fi network afterward.
8. Wi-Fi Router Firmware: Check if there are any firmware updates available for your Wi-Fi router. Outdated router firmware can cause compatibility issues and lead to unstable connections. Refer to your router's manual or manufacturer's website for instructions on how to update the firmware.
9. Contact your Internet Service Provider (ISP): If the issue persists, it's possible that the problem lies with your internet service provider. Contact your ISP and describe the Wi-Fi connectivity problems you are experiencing. They may be able to provide guidance or troubleshoot the issue on their end.

If none of the above steps resolve the problem, it could indicate a hardware issue with your Samsung Galaxy A21s or the Wi-Fi router. In such cases, it's recommended to contact Samsung support or your router manufacturer for further assistance or consider visiting a service center for professional help.
