What to do if wifi connection keeps dropping on Galaxy S10

If your internet via wifi disconnects without obvious reasons, there may be a number of possible reasons for it. Troubleshooting this issue requires numerous numbers of steps to do. Follow the steps below to fix the issue.

Restart the phone

If wifi has started acting up for no apparent reason, the first troubleshooting step that you want to do is to refresh the device. Many connectivity problems are temporary and often develops after when a device has run continuously for some time. Try to restart the device normally at first to see if that helps. If nothing changes, consider simulating the effects of a battery pull. Here’s how to do that:

  1. Press and hold the Power + Volume Down buttons for approximately 10 seconds or until the device power cycles. Note: Allow several seconds for the Maintenance Boot Mode screen to appear.
  2. From the Maintenance Boot Mode screen, select Normal Boot. Note: Utilize the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Also, allow up to 90 seconds for the reset to complete.

Forget wifi

Many cases of wifi problems are fixed by doing a simple step: disconnecting the connection. If you haven’t tried it yet, make sure to do it. Just tap on the wifi icon, disconnect your S10 from your wifi network, then reconnect after a few seconds. If this step won’t work, proceed to the next one.

Restart router and other networking equipment

If you’re having trouble with your home wifi only, it’s possible that your router and other other devices in the network may need refreshing. Try to do a sequential power cycle of all networking equipment and see what happens. This is often effective in fixing local bugs in a home network. Disconnect the router from the power outlet for at least 10 seconds before plugging it back in. If you have other networking equipment connecting to the router, make sure to unplug them from the power source for 10 seconds too. This will allow the devices to refresh their system.

Confirm wifi is working normally

Before doing any further troubleshooting on your Galaxy S10, it’s a good idea to confirm if the problem comes from the router itself. Are there other wireless device experiencing the same problem? If there are more devices with the same situation, it’s likely a router or Internet Service Provider (ISP) problem. Be sure to talk to your ISP to get support.

Reset network settings

If all other devices in your home network are not experiencing disconnections at all, then you need to focus your troubleshooting on your S10. There may be some network settings that must be reconfigured to fix it. To ensure that all network settings are configured correctly, you can reset the network settings of your S10. Here’s how:

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

Toggle Airplane Mode on and off

Sometimes, turning Airplane Mode on and off can fix network issues. Make sure to toggle Airplane Mode on and off if nothing has worked so far.

Wipe cache partition

At times, problems may occur if the system cache is corrupted. Android uses a set of temporary files in order to load apps quickly. Updates or app installations may corrupt this cache, which can then lead to problems. To keep the system cache in good shape, try to clear the cache partition. 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 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 to highlight “wipe cache partition.”
  5. Press the Power key to select.
  6. Press the Volume down key to highlight “yes” and press the Power key to select.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

Install updates

Installing updates is often regarded as less important than other troubleshooting steps in this case. The fact is, some issues are only fixable by changing some codes. This is true whether you have an app issue or software problem. Make sure to keep your apps and Android OS updated by installing updates for them regularly. If you have third party apps taken outside the Play Store, be sure to check with their developers if their product is compatible with the current software running on your S10. At times, there are incompatibility issues that can happen when Android receives an update and an app is not updated to work with it.

Check for bad apps

Another possible reason for your problem may be a bad app. We’re talking about possible third party app that you installed immediately before the problem started, or a poorly coded app that became problematic after an update. To check if one of the apps is to blame, boot the device to safe mode. In this mode, all third party apps will be suspended and won’t be running. If your S10 charges normally and fast on safe mode only, that means that you have a bad app problem.

To restart your device to safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the model name 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. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.

To identify which of your apps is the source of trouble, you must use elimination method. Here’s what you can do:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your S10 is still problematic, repeat steps 1-4.

Factory reset

Should none of the steps above help, you should not hesitate to wipe the phone with factory reset. Before you factory reset, make sure to create a backup of your personal data.
