How to Fix a Samsung Galaxy S25 Ultra Wi-Fi Connection That Keeps Dropping

A consistently dropping Wi-Fi connection on your Samsung Galaxy S25 Ultra can be incredibly disruptive. This tutorial provides a comprehensive guide to troubleshooting and resolving this frustrating issue.

1. Toggle Wi-Fi On and Off

Sometimes, a simple toggle can refresh the Wi-Fi connection and resolve minor glitches. A quick on/off cycle resets the connection.

1. Swipe down from the top of the screen to access the quick settings panel.
2. Tap the Wi-Fi icon to turn it off.
3. Wait a few seconds, then tap the Wi-Fi icon again to turn it back on.

2. Restart Your Phone

A basic restart can often clear temporary software issues that might be affecting the Wi-Fi connection. Rebooting resets the device’s operating system.

1. Press and hold the Power button.
2. Tap Restart.
3. Wait for your phone to restart.

3. Restart Your Router

Like your phone, your router can also experience temporary glitches. Restarting it can refresh the network connection. A router restart can resolve network related issues.

1. Unplug the power adapter from your router.
2. Wait for 30 seconds.
3. Plug the power adapter back into your router.
4. Wait for your router to fully restart.

4. Forget and Reconnect to the Wi-Fi Network

Forgetting and reconnecting to the Wi-Fi network can clear saved network settings that might be corrupted. This forces your phone to establish a new connection.

1. Open the Settings app.
2. Tap on Connections.
3. Tap on Wi-Fi.
4. Tap the gear icon next to your Wi-Fi network.
5. Tap Forget.
6. Select your Wi-Fi network from the list and enter your password.

5. Check for Software Updates

Outdated software can contain bugs that affect Wi-Fi connectivity. Updating your phone’s software can resolve these issues. Updates often include fixes for known problems.

1. Open the Settings app.
2. Tap on Software update.
3. Select Download and install.
4. Follow the on-screen instructions if an update is available.

6. Check for App Interference

Certain apps might interfere with your Wi-Fi connection. Booting into safe mode helps determine if a third party app is the cause.

1. Press and hold the Power button.
2. When the Samsung logo appears, release the Power button and immediately press and hold the Volume Down button.
3. Continue holding the Volume Down button until the phone finishes restarting. “Safe mode” will appear in the bottom left corner.
4. Test your Wi-Fi connection in safe mode. If it works, an app is the problem.

7. Change Wi-Fi Frequency Band

Some routers support both 2.4GHz and 5GHz bands. Switching between them can sometimes improve stability. Different bands have different characteristics.

1. Open the Settings app.
2. Tap on Connections.
3. Tap on Wi-Fi.
4. Tap the gear icon next to your Wi-Fi network.

1. Open the Settings app.
2. Tap on General management.
3. Tap on Reset.
4. Tap on Reset network settings.
5. Confirm the reset.

9. Check Router Firmware

Outdated router firmware can also cause connection issues. Updating your router’s firmware can improve performance and stability. Routers require updated software to perform optimally.

1. Access your router’s settings through a web browser (usually by typing 192.168.1.1 or 192.168.0.1 into the address bar).
2. Log in with your router’s username and password.
3. Look for a firmware update section in the settings.
4. Follow the on-screen instructions to update the firmware.

10. Check for Physical Obstructions

Physical obstacles can interfere with Wi-Fi signals. Removing these obstacles can improve signal strength. Walls, metal objects, and other electronic devices can weaken signal strength.

1. Ensure your router is placed in a central location.
2. Remove any physical obstacles that might be blocking the Wi-Fi signal.
3. Keep your phone within a reasonable distance from the router.

11. Check for Interference from Other Devices

Other electronic devices can interfere with Wi-Fi signals. Minimizing interference can improve connection stability. Microwaves, cordless phones, and other wireless devices can cause interference.

1. Keep your router away from other electronic devices.
2. If possible, change the Wi-Fi channel on your router to minimize interference.

By systematically working through these steps, you should be able to identify and resolve the issue causing your Samsung Galaxy S25 Ultra’s Wi-Fi connection to drop. If the problem persists, it’s advisable to contact your internet service provider or Samsung support for further assistance.
