Fixing Galaxy S10 that disconnects from WiFi by itself

Network-related problems are more of an annoyance than serious issues provided that your phone doesn’t have physical damage. They’re often due to a glitch in the system or a problem with the network devices. With that being said, here are the things you need to do if your phone disconnects from WiFi on its own…

First solution: Force restart your device

At this point, we don’t know the reason why your phone disconnects from the WiFi network it’s getting internet connection from. If it didn’t have issues with the network prior to the problem, then it’s possible that it’s just due to a minor firmware issue or even just a glitch. So, the first thing you must do is something simple like forced restart and here’s how it’s done:

  1. Press and hold the volume down button first and don’t let it go.
  2. While holding down the volume button, press and hold the power key as well.
  3. Keep them held down together until the Galaxy S10 logo appears on the screen.

After this, make sure to have your device connected to the same network and then wait and see if it still disconnects from WiFi network because if it still does, then it’s not just an issue caused by a glitch or minor firmware problem. Move on to the next solution.

Second solution: Power-cycle your network devices

Let’s now try to rule out the possibility that this problem is caused by your network devices such as your router or modem. It happens so often that network devices crash or intermittently stops broadcasting signal and it could be the reason why your phone disconnects from the network or loses connectivity. If this is the only problem, then you can fix it by doing the following steps:

  1. Unplug your network devices from the wall outlet.
  2. Leave them without power for a minute or two.
  3. While waiting, it’s better to reboot your phone as well.
  4. Plug the network devices to the wall outlet and wait until they start broadcasting signal.
  5. Let your phone reconnect to the network.

Continue using your phone to know if it still disconnects from WiFi network after doing this. If it still does, then you have to do the next procedure.

Third solution: Reset Network Settings

When it comes to network related problems, this procedure will often fix them but it’s not focused on WiFi alone. Other wireless connections will also be affected by this and they will be brought back to default settings. Don’t worry, none of your files and data will be deleted if you did this but 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.

Now, here’s how you reset the network settings in your phone…

  1. Swipe down from the top of the screen to pull the notification panel down.
  2. Touch the settings icon on the top-right corner of the screen.
  3. Scroll to and tap General management.
  4. Touch Reset.
  5. Tap Reset network settings.
  6. Tap reset settings and enter your PIN, password or pattern.
  7. Now, tap Reset to confirm your action.

After doing this, continue using your phone to know if it still disconnects from WiFi network and if it still does, then you it’s time to troubleshoot the firmware.

Fourth solution: Delete the system cache

The system creates a cache for all services, functions and features of your Galaxy S10. The cache is a collection of small files the firmware uses to make your phone run smoothly. And while these files can be deleted without any adverse effects to your device, it’s a different story if they get corrupted because it happens, performance issues may occur. So, in this step, try deleting the system cache so that it will be replaced with a new one. Here’s how it’s done:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the Galaxy S10 logo shows on the screen, release all keys.
  4. Press the Volume down to highlight ‘wipe cache partition’.
  5. Press Power button to select.
  6. Press the Volume down key to highlight ‘Yes’.
  7. Press Power button to select and wipe the cache partition.
  8. When the master reset is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

It may take a little while for your phone to boot up after this since it will rebuild the cache but if the your phone still disconnects from WiFi after doing this procedure, then you have no other choice but to reset your phone.

Fifth solution: Backup your files and reset your device

If all else failed to fix the problem with your Galaxy S10, then you should reset it. It will address all possible firmware-related problems that may have affected your phone’s capability to stay connected with the WiFi network. However, before you reset your device, make sure to backup your files and data and remove your Google and Samsung accounts so that you won’t be locked out of your device after the reset. Once everything is set, follow these steps:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the Galaxy S10 logo shows on the screen, release all keys.
  4. Press the Volume down to highlight ‘wipe data / factory reset’.
  5. Press Power button to select.
  6. Press the Volume down key to highlight ‘Yes’.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.
