Are there any settings I can adjust to improve the weak and fluctuating Wi-Fi connection on my Samsung Galaxy S10 Lite?

Yes, there are several settings you can adjust on your Samsung Galaxy S10 Lite to potentially improve your Wi-Fi connection. Here are some steps you can take:

1. Restart your phone and router: Sometimes, a simple restart can resolve connectivity issues. Turn off your phone and the Wi-Fi router, wait for a few seconds, and then turn them back on.
2. Move closer to the router: If you're experiencing weak or fluctuating Wi-Fi, try moving closer to your Wi-Fi router to ensure a stronger signal.
3. Forget and reconnect to the network: Sometimes, there may be an issue with the saved network settings. Go to your phone's Settings, tap on "Wi-Fi," and then tap and hold the network you're connected to. Select "Forget network," and then reconnect to it by entering the password.
4. Reset network settings: Resetting your network settings can resolve various connectivity issues. Note that this will remove all saved Wi-Fi networks and Bluetooth pairings. To reset network settings, go to Settings > General Management > Reset > Reset Network Settings.
5. Disable Wi-Fi power saving mode: By default, Samsung devices have a power-saving mode for Wi-Fi that can affect the connection stability. To disable it, go to Settings > Wi-Fi > Advanced > Wi-Fi Power Saving Mode, and toggle it off.
6. Change Wi-Fi frequency band: Some routers offer both 2.4 GHz and 5 GHz frequency bands. While 2.4 GHz has better range, 5 GHz offers faster speeds and is less prone to interference. You can try switching to the 5 GHz band if your router supports it. Go to Settings > Wi-Fi, tap on the network name, and select the desired frequency band.
7. Enable "Keep Wi-Fi on during sleep": By default, your phone may turn off Wi-Fi during sleep mode to conserve battery. However, this can cause delays when waking the device. To change this setting, go to Settings > Wi-Fi > Advanced > Keep Wi-Fi on during sleep, and select "Always."
8. Update your phone's software: Ensure that your Samsung Galaxy S10 Lite has the latest software updates installed. Software updates often include bug fixes and performance improvements that can enhance Wi-Fi connectivity.
