What to do if Galaxy Tab S4 can’t connect to Wifi

Network-related issues may occur from time to time but it doesn’t mean they’re serious. There are times when they’re caused by some glitches in the system and there are times when some apps interfere with its normal operation. With all that being said, here’s what I suggest you do about it…

Solution 1: Forced Reboot

If this is the first time that your tablet cannot connect to a Wifi network, then try doing the forced reboot as it could be just due to a minor glitch in the system. It will refresh your device’s memory as well as reload all its apps and services. It might be the only thing you need to do and here’s how you do it:

  1. Press and hold the Volume down button first and don’t release it.
  2. Now, press and hold the Power key while holding down the Volume down button.
  3. Keeps both keys held down together for 45 seconds or more.

Once the phone has rebooted successfully, try reconnecting to the same Wifi hotspot to see if the problem got fixed. If it still can’t connect, then try the next solution.

Solution 2: Reboot Network Equipment

The next thing you should do if make sure it’s not a problem with the network. If you’re connecting to your own Wifi network, then it’s better to refresh the connection by rebooting your router or modem. Just unplug your equipment for a minute or two and then plug it back in. Once it’s ready, try having your tablet reconnect to the network and if it still can’t, then try your other devices to connect to the same network.

If your other devices cannot connect to the same network, then it’s a problem with your router or modem. You may have to reset it. However, if they can connect to the network and browse the web, then the problem is with your tablet. Continue your troubleshooting.

Solution 3: Reset Network Settings

There are times when network services may stop working and just need to be refreshed. So, you need to reset network settings to refresh the connection. Here’s how it’s done…

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > General Management > Reset > Reset network settings.
  4. If you have set up a PIN, enter it.
  5. Tap RESET SETTINGS. Once complete, a confirmation window will appear.

Once completed, the following changes will occur…

  • Stored Wi-Fi networks will be deleted.
  • Paired Bluetooth devices will be deleted.
  • Background data sync settings will be turned on.
  • Data restrictive settings in applications that were manually turned on/off by the customer will be reset to the default setting.
  • Network selection mode will be set to automatic.

If the problem continues after this, then try the next solution.

Solution 4: Reset All Settings

This will bring back the phone to its original configuration. Most of the time, this will fix any minor problems including network issues. It has the effects of a factory reset only that you don’t need to create a backup of your important files and data as they won’t be deleted. Here’s how it’s done on your Tab S4:

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > General Management > Reset > Reset settings.
  4. If you have set up a PIN, enter it.
  6. The device will restart to perform the reset of settings.

Solution 5: Master Reset

After you’ve done everything and your Tab S4 still can’t connect to the network, then you need to reset your phone. A reset will fix any firmware related problems as long as the firmware hasn’t been modified in any way. However, make sure that you create a backup of your important files and data as they will be deleted during the problem. Once you’re ready, follow these steps to perform the Master Reset:

  1. Back up data on the internal memory. If you have signed into a Samsung account on the device, you have activated Anti-theft and will need your Samsung credentials to finish the master reset.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.
