How to troubleshoot a Galaxy phone that won't connect to a Wi-Fi network
When you have difficulty connecting to Wi-Fi on your phone, you need to check whether the Wi-Fi signal is not found or if the Wi-Fi network is found but cannot connect. Check out the guide below to successfully get your Wi-Fi network online.
Note: Be sure to check if your device's software and related apps are updated to the latest version.
What to do if the Wi-Fi network is not detected?
There can be various reasons for the problem of not being able to connect to the Wi-Fi network normally. For example, the router may not be working properly or there may be an issue with your phone's network settings. Check out the guide below.
Check if the router is working properly. Make sure that it's powered on, connected to the Internet, and that your phone is within the router's Wi-Fi range. In addition, if too many devices are connected to one router, the Wi-Fi may not be detected.
Note: The router display may vary from device to device. Check with your router provider.
Try restarting your Galaxy phone, router, and modem.
Step 1. Press on the Volume down button and Power button at the same time.
Step 2. Tap on Restart to reboot your device.
Step 3. Turn your router and modem off and on again. When turning the router and modem off, unplug the power plug and plug it back in, and then turn on the power.
Step 4. After you restart each device, see if you fixed the issue.
Step 1. Go to Settings, and then select General Management.
Step 2. Choose Reset.
Step 3. Tap on Reset network settings.
Step 4. Tap on Reset settings.
Note: After tapping Reset Settings, you will need to confirm the reset process using your pattern, password, or pin code.
Try the Wi-Fi connection in Safe mode. If the Wi-Fi network is connected in Safe Mode, it may be a problem caused by the downloaded app on your phone, and that app should be uninstalled. To find which app causes a Wi-Fi issue, you can try uninstalling the apps in the order of the last installation.
Step 1. Press and hold the Volume down key and the Side key.
Step 2. Select Power off.
Step 4. Once the Samsung logo appears on the screen, release the Side key while holding the Volume down key.
Step 5. When Safe mode appears on the lower left corner of the screen, release the key. Try updating in Safe mode.
Note:
- You can restart the device to turn off Safe mode.
- Volume and Side key locations may vary depending on the device model.
To forget a network, follow the steps below:
Step 1. Hold and drag down the notification panel.
Step 2. Tap and hold the Wi-Fi icon.
Step 3. Tap on the Settings icon.
Step 4. Tap on Forget.
Disable and re-enable Airplane mode from the Notification panel.
If the above methods do not work, you may bring your device back to the factory default settings just like when you powered on your device for the first time.
Step 1. Go to Settings, and then select General management.
Step 2. Select Reset, and then tap on Factory data reset.
Step 3. Scroll down the page and tap on the Reset button.
Step 4. Tap on the Delete all button.
Note:
- Factory data resetting a mobile device is not reversible.
- Make sure that all of your information is saved to a backup somewhere else before attempting to reset your phone.
Note:
- If you're connected to a Wi-Fi network but cannot get online, try using the Wi-Fi network on another device. If other devices also cannot access online, that network service may be faulty, so contact your Internet provider for help.
- Device screenshots and menus may vary depending on the device model and software version.
