How to fix Galaxy S10 won’t connect to wifi issue

Dealing with a non-working wifi connection is one of the annoying problems a Samsung Galaxy S10 user can face. Fortunately, the solutions are often handy and easy to do. This troubleshooting article will show you the solutions to try in this case.

Solutions to Galaxy S10 won’t connect to wifi issue

Forced reboot. This is one of the basic troubleshooting steps that you need to do when troubleshooting any Android issue. It’s simple and often effective in dealing with minor bugs and fixes. In most instances, wifi troubles are temporary and caused by an app or software bug. Make sure to perform this troubleshooting step in this case. Here’s how: press and hold the Volume Down button and the Power key at the same time for 10 seconds or until the device’s screen turns on.

If doing the regular restart won’t help, then try this:

  1. Press and hold the Volume Down button first and don’t release it.
  2. While holding it down, press and hold the Power key.
  3. Keep both keys held down for 10 seconds or more.

The second restart procedure tries to simulate the effects of removing the battery pack. On older devices, disconnecting the battery is often an effective way in fixing unresponsive devices. Hopefully, your wifi troubles will get fixed by this procedure. If nothing changed though, proceed to the next suggestions.

Confirm wifi is working. If your Galaxy S10 is able to connect to the wifi network but there’s no internet connection, that’s probably a wifi trouble. You must resolve the wifi problem first by troubleshooting the router or your network. To do that, you must contact your Internet Service Provider who provided the router. Alternatively, you can try to confirm whether it’s a wifi issue by connecting your S10 to another router. If wifi works on the second network, then that means there’s no problem with your device at all. The most that you should do is to forget the wifi network with the problem and see if it works fine again.

Troubleshooting your problem wifi network includes the following:

  • Restarting the router.
  • Installing router software updates.
  • Resetting network configuration of the router.

If you don’t know how to troubleshoot the router, get support from your ISP (Internet Service Provider).

Forget wifi. Disconnecting from a problem wifi network is often an effective way to fix Samsung Galaxy wifi woes. Simply tap the wifi icon and disconnect the device from the network. After that, restart the phone and see if that fixes the problem. If not, proceed to the next steps.

Cache partition wipe. Some bugs are caused by corrupted system cache. To ensure that your Galaxy S10 system cache is fresh, you have to clear the cache partition from time to time. Here’s how to do that:

  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 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).
  4. Press the Volume down key several times to highlight ‘wipe cache partition’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘yes’ is highlighted and press the Power button.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

Reset network settings. Resetting a device’s network settings is one of the most important troubleshooting step that you need to do in this case. By doing this, you are effectively wiping all network configurations including all the wifi networks saved as well as their passwords. To clear network settings:

  1. Open Settings app.
  2. Tap General management.
  3. Tap Reset.
  4. Tap Reset Network settings.
  5. Tap RESET SETTINGS button to confirm.
  6. Restart your S10 and check for the problem.

Safe Mode. To check for a possible issue with a third party app, we also suggest that you run your S10 on Safe Mode before connecting to wifi again. While Safe Mode is active, only preinstalled apps will run. This means that if wifi works normally on this mode but not while on normal mode, a bad third party must be causing the trouble. These are the steps to restart to safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen appearing on the screen.
  3. When SAMSUNG appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. When Safe mode appears in the bottom left corner of the screen, release the Volume down key.
  7. While in Safe mode, you can now uninstall apps that are causing a problem.

Factory reset. In many cases, factory reset is not necessary in fixing wifi problems. However, if none of the troubleshooting steps above has not helped so far, you must do it on your phone. Make sure to create a backup of your personal data ahead of time to avoid losing them. You can use Samsung Smart Switch to back them up.

To factory reset your Galaxy S10:

  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 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).
  4. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, ‘Reboot system now’ is highlighted.
