[Wodehouse]

Here's a breakdown of troubleshooting steps to fix your Samsung Galaxy M21's Wi-Fi disconnection issue:
1. Basic Checks:
* Restart: Restart your phone and router. This often resolves temporary glitches.
* Distance: Ensure you're within the router's Wi-Fi range. Walls and obstacles can interfere with the signal.
* Interference: Identify potential sources of interference like microwaves, cordless phones, or other electronic devices.
2. Software-Related Solutions:
* Forget and Reconnect:
* Go to Settings > Connections > Wi-Fi.
* Tap the gear icon next to your Wi-Fi network.
* Select "Forget."
* Reconnect to your network and enter the password.
* Software Update: Check for and install any available software updates for your phone. Updates often include bug fixes and improvements.
* Power Saving Mode:
* If Power Saving Mode is enabled, it might be aggressively disconnecting Wi-Fi to conserve battery. Adjust the settings accordingly.
* Reset Network Settings:
* Go to Settings > General Management > Reset > Reset Network Settings.
* This will reset Wi-Fi, mobile data, and Bluetooth settings.
3. Router-Related Solutions:
* Router Firmware: Update your router's firmware to the latest version. This can improve stability and performance.
* Router Settings:
* Channel: Try changing the Wi-Fi channel on your router. Overlapping channels from neighbors can cause interference.
* Security: Ensure you're using a strong and compatible Wi-Fi password (WPA2/WPA3).
* DHCP: Check if your router's DHCP server is functioning correctly. This assigns IP addresses to devices on your network.
4. Advanced Troubleshooting:
* Check for Hardware Issues: If the issue persists, there might be a hardware problem with your phone's Wi-Fi module.
If the problem continues:
* Contact Samsung Support: They can provide further assistance or suggest taking your phone to a service center for repair.
Important Notes:
* The exact steps may vary slightly depending on your Android version and phone model.
* If you're not comfortable with any of these steps, consult with a tech-savvy friend or take your phone to a qualified technician.
I hope these steps help you resolve the Wi-Fi disconnection issue on your Samsung Galaxy M21!
