My Galaxy Device won't connect to Wi-Fi

Last modified : Sep 27. 2019

If you're having trouble getting your Samsung phone or tablet connected to your Wi-Fi network, there are some troubleshooting steps on this page to help. If your device can't find any Wi-Fi networks to connect to - please see the page on Mobile Device can't Find Wi-Fi networks.

Please note: Any prompt that says "Authentication Error" is related to an incorrect password. Please contact your Internet Service Provider for assistance in changing your Wi-Fi network password. 

Wi-Fi Network Troubleshooting

1 Forget the Network

Head into the Settings on your device and find the Wi-Fi networks page under Connections. Tap and hold the Wi-Fi network that you're having trouble with until the menu allows you to select Forget Network. This will remove any saved information on your device that could be interfering with the authentication. Try to enter the password of the network again.

Forget the Network and Try to reconnect
2 Reset Network Settings

Resetting the network settings will clear out anything potentially interfering with the network connectivity. It will reset:

  • Wi-Fi information
  • Mobile data information (which will be read from your SIM card and re-saved to the device automatically)
  • Bluetooth connections

Steps for Android 9 (Pie)

  • Settings > General Management > Reset > Reset Network Settings

Steps for Android 7 (Nougat) and Android 8 (Oreo)

  • Settings > General Management > Reset > Reset Network Settings

Steps for Android 6 (Marshmallow)

  • Settings > Backup & Reset > Reset Network Settings
3 Try Connecting using the WPS Push Button

If your router supports the Wi-Fi Protected Setup (WPS) Push Button, try connecting the two via the below steps. Connecting your Galaxy device using the WPS Push Button will allow you to connect to your Wi-Fi without having to enter in the Wi-Fi password. 

  • Settings > Connections > Wi-Fi > Advanced > WPS Push Button 

Ensure that you also tap the WPS Button on your Router to connect the two.

Pressing the WPS Push Button

WPS Push Button setting isn't available on Galaxy devices operating on Android OS Version 9.0 (Pie).

4 Power cycle the Router and Mobile Device

Power off your Router (at the wall or with the power button on the router) and wait 2-3 minutes to turn it back on. While you're waiting, press thePower button on your mobile device and select Restart. 

Once the router has successfully connected to the internet again, try to connect to your network on your mobile device.

Make sure there is no interference between the router and your mobile device. Concrete walls, fridges and microwaves can all interrupt the Wi-Fi signal.

5 Toggle Airplane or Flight Mode

We can try to eliminate any other network connections while you're trying to connect to the Wi-Fi network by making sure Airplane or Flight mode is turned off.

Check Flight Mode by swiping down from the top of the screen on your device with two fingers to access all of the Quick Settings. Find the Airplane/Flight mode option and turn it off - or toggle it on and off again to be sure.

6 Try to connect in Safe Mode

Safe mode will restrict any 3rd party applications that could be interfering with your device being able to connect to a Wi-Fi network. If you can connect to Wi-Fi networks while the device is in Safe Mode; you'll need to uninstall whichever app is causing the issue. Finding the app that is causing the problem is a task onto itself; it's best to start with apps most recently downloaded and work backwards. You can always re-install apps that were mistakenly uninstalled.

Put your phone or tablet into Safe Mode:

  1. Turn your device Off
  2. Hold the Volume Down and Power buttons at the same time to turn the device on.
  3. Let go of the Power button when the Samsung logo appears on the screen

When the device turns on, you should see "Safe Mode" at the bottom left corner. To get out of Safe Mode, restart your device.

7 Check that you are in range

Next to the Wi-Fi network you are trying to connect is an icon which indicates the strength of the signal. Having a weak signal may cause connectivity issues. If you are receiving a weak signal, try moving closer to the Wi-Fi source and connect again.


If you are unable to move closer to the Wi-Fi source, place a Wi-Fi extender in between your location and the location of the router. Wi-Fi extenders can be purchased from most electronics stores.

The last steps in determining whether the Wi-Fi connectivity issues are software or hardware related are to Back up the Data and perform a Factory Data Reset of the device. Should a Factory Reset not resolve the problems around connecting to Wi-Fi, it is possible that there is a hardware issue with your device.
