I can't connect to Wi-Fi on my Samsung Galaxy device

If you're having trouble connecting to Wi-Fi on your Galaxy device, there are a number of things you can try, such as performing a soft reset, adjusting your settings, and forgetting the network. Follow our tips to get your device connected.

If you are looking for information on how to connect your Samsung TV to the internet, read our FAQ to find out how to check the internet settings on your TV.

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.
  • To view the password you are entering tap the eye symbol next to “Enter password”. You should check the password you are using against other devices using the same Wi-Fi connection.

Samsung is aware of this issue and will release an improved software version soon. The available date for this update may differ depending on the country or mobile carrier. It is recommended to keep the software on your device updated to the latest version. Find out more about how to update the software on your device.

Until the new software version is available, follow the steps below to establish a Wi-Fi connection.

Register the Wi-Fi again after resetting the network settings

1 Open the Settings app
2 Tap General management
3 Tap Reset
4 Tap Reset network settings
5 Tap Reset settings
6 Register your Wi-Fi network again to connect

You can also try re-entering the password for your Wi-Fi network

1 Open the Settings app
2 Tap Connections
3 Tap Wi-Fi
4 Tap the Wi-Fi network you want to join
5 Enter your Wi-Fi password

Press and hold the power and volume down buttons on your device for around 10-15 seconds. Your device will restart. Try connecting to Wi-Fi again.

Please note: the image below shows the location of the volume down and power buttons on the S21 Ultra 5G. The location of these buttons may differ depending on your device.

There are a few settings on your device that may be preventing you from connecting to Wi-Fi. Check that your settings are correct for Wi-Fi access.

1 Swipe down twice from the top of the screen to open your quick settings
2 Make sure that the Wi-Fi setting is turned on

Please note: if a setting is turned on, it will be blue. If a setting is turned off, it will be grey

3 Make sure that the Airplane Mode setting is turned off
4 Make sure that Power saving mode is turned off

Once you've changed your settings, try and connect to Wi-Fi again.

Next to the Wi-Fi network you are trying to connect to 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.

You can use the Samsung Members app to diagnose Wi-Fi connectivity issues. Open Samsung Members, go to Get help and tap Start under Diagnostics and select Wi-Fi to test it.

If the Wi-Fi network that you want to join is not appearing, it is likely that there is an issue with your Wi-Fi signal or router.

  1. Switch off your Wi-Fi router at the wall and wait 2-3 minutes before turning it back on. Once the router has successfully connected to the internet again, try to connect to your network on your mobile device.
  2. Some Wi-Fi routers support both 2.4GHz and 5GHz. Most Galaxy devices will switch between these channels automatically when required. For example, when you are closer to the router your device will switch to 5GHz and swap to 2.4GHz when further away.
  3. 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.
  4. If possible, try and connect your device to a different Wi-Fi connection. If you can connect, you should contact your Wi-Fi provider for more assistance.

If you have previously managed to connect to the Wi-Fi network and you are now having trouble joining, it may help to forget the network and reconnect.

1 Go to Settings
Tap to enter the Settings menu
2 Tap Connections
Tap Connections
3 Tap Wi-Fi
Tap to enter Wi-Fi menu
4 Tap the Settings icon next to the Wi-Fi network you are having trouble with
Tap the Settings icon next to the Wi-Fi network you are having trouble with
5 Tap Forget

This will remove any saved information on your device that could be interfering with the authentication.

Please note: if you want your device to automatically connect to this Wi-Fi network in the future, make sure that the switch next to Auto reconnect is switched on.

6 Try to reconnect to the network again by tapping the network and entering the password, if required.

If you are connecting to a home Wi-Fi network, check if the other devices you own can connect. If you are unable to connect with any of your devices, the issue is likely with your Wi-Fi. 

If you are able to connect using another device, check for and install any available software updates for your Galaxy device, then try connecting again.

Safe mode can be used as a diagnostic tool that lets you run your device at the basic interface without any third-party apps. This helps to determine if the issue you are facing is due to an installed app.

1 Press and hold the power button or button combination you use to turn off your device until the power off screen appears

Please note: the image below shows the button combination for the S21 Ultra 5G

2 Tap and hold the Power off icon until the option for Safe mode appears
3 Tap Safe mode
4 Your device will restart and open in Safe mode. Try and connect to Wi-Fi

If your device is still unable to connect, it is likely that one of your apps is causing the issue. Starting from the most recently installed, you should try deleting apps until you find which one is causing the problem. You can always re-install any apps that were mistakenly deleted.

If you're experiencing unusual behaviour on Samsung mobiles, tablets or wearables, you can send us an error report or ask us a question in the Samsung Members app.
