What can I do to fix the weak Wi-Fi signal on my Samsung Galaxy S21?

To fix the weak Wi-Fi signal on your Samsung Galaxy S21, you can try the following steps: 1. Move closer to your Wi-Fi router: Ensure that you are within range of your router to get a stronger signal. 2. Restart your Wi-Fi router: Turn off your router, wait for a few seconds, and then turn it back on. 3. Reset network settings: Go to Settings > General Management > Reset > Reset Network Settings. This will remove all saved Wi-Fi networks, so you'll need to reconnect to them. 4. Toggle Wi-Fi off and on: Swipe down from the top of your screen to access the Quick Settings panel, and tap the Wi-Fi icon to turn it off. After a few seconds, tap it again to turn it back on. 5.

Go to Settings > Software Update > Download and install to check for any available updates. 7. Disable battery optimization for Wi-Fi: Open Settings > Battery and Device Care > Battery > App Power Management > More options > Sleeping apps. Find and remove Wi-Fi from the sleeping apps list. 8. Enable Wi-Fi calling: If your carrier supports it, Wi-Fi calling can improve your signal strength. Go to Settings > Connections > Wi-Fi Calling and enable the feature if available. 9. Factory reset: If all else fails, you can perform a factory reset on your Samsung Galaxy S21. Make sure to backup your data before proceeding, as this will erase all your device's content and settings. Go to Settings > General Management > Reset > Factory data reset.
