How to troubleshoot WiFi issues with Galaxy Note 9

Internet connectivity issues are often minor problems that any user could be able to fix regardless of the device they’re using. When it comes to the Galaxy Note 9, fixing these types of issues are a lot easier since the device itself is built to be connected to a network that allows internet access and that by default, the device is programmed to automatically connect to trusted networks.

One of the effective solutions that would help you fix a connectivity or network issue is by resetting network settings. This will reset all data connections back to the out of the box factory defaults and 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.

So basically, after doing the procedure, you will have to turn the WiFi back on to detect the hotspot you usually connect to and continue your observation. Now, here’s how you reset the connection settings in your Galaxy Note 9:

  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.
  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.

If the problem continues to manifest after this procedure, try resetting all settings in your phone as there could be some incorrect settings in your phone. It almost has the same effects as with the full reset only that your files and data will not be deleted. Here’s how you do that:

  1. From a Home screen, swipe up or down from the center of the display to access the apps screen.
  2. Navigate: Settings Settings icon > Backup and reset.
  3. From the Reset section, tap Reset settings.
  4. Review the info then tap RESET SETTINGS.
  5. If presented, enter the current PIN, password, or pattern.
  6. To confirm, review the info then tap RESET SETTINGS.

Should the problem continue after all this, then it’s more than just an issue with phone’s radios. Continue reading to know how to troubleshoot your Galaxy Note 9 that keeps on disconnecting from a WiFi hotspot.

Determine if it’s due to an app or a malfunctioning service

There are apps that can interfere with your phone’s capability to connect to a network and there are those that can actually manipulate the device’s connectivity features. Most of the time those apps or services are installed by carriers or service providers for reasons that are beneficial to them. Those apps can actually be disable or uninstalled but the best thing to know if the WiFi issue is due to some apps or services is by running your phone in Safe mode. In this environment, all third-party apps are temporarily disabled and only the core services are loaded during the boot process. Don’t worry, this procedure is safe to both your phone and your files and this is how you do it:

  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.

If the problem actually disappears while in this mode, then the next thing you should do is find the app that’s causing the problem and uninstall. However, if the issue is still happening, then move on to the next step.

But here’s how you uninstall all app from your Note 9:

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > Apps.
  3. Tap the desired application in the default list or tap 3 dots icon > Show system apps to display preinstalled apps.
  4. Tap the desired application.
  5. Tap Uninstall.
  6. Tap Uninstall again to confirm.

Try deleting all system caches

System caches, while they’re temporary small files, actually are important to make your phone, its apps and services run smoothly. When a certain cache gets corrupt and the system continues to use it, it could affect the overall performance of your device depending on what the cache is for. To rule out the possibility that this problem is due to some corrupt caches, delete all of them so they’ll be replaced with new ones. Don’t worry, after you deleted them, the firmware will automatically create new caches:

  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.

After the reboot, try to see if the WiFi still disconnects or manifests similar problems and if so, then you have no other choice but to reset your phone.

Backup all your files and reset your Note 9

A reset can fix this problem as long as it’s not an issue with the hardware used by the device to receive and transmit radio signals. But your device will certainly be brought to its factory default settings and all your personal files and data will be deleted. So take time backing them up especially your contacts, pictures, videos, music, messages,etc. After the backup, make sure to disable the Factory Reset Protection by removing your Google account from your device so that you won’t be locked out after the reset. Once everything is set and ready, follow these steps to do the Master Reset:

  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.
  9. Press the Power key to restart the device.

If the problem still happens after this, then you should bring the device to the service center because it might already be an issue with the hardware. The store may replace your phone with a new one depending on the diagnosis of the tech.
