Troubleshooting Note 9 with WiFi connection problem after an update

The course of this troubleshooting guide will be to rule out every possibility until we can determine why it’s happening and finally fix the problem. With all that being said, here are the things you need to do…

Force restart your Galaxy Note 9

Let’s begin our troubleshooting with a very simple procedure but very effective in dealing with minor software related problems including glitches and crashes. By doing the forced reboot, you’re refreshing your phone’s memory as well as reloading its apps and data. Press the volume down and power keys at the same time and hold them both together for 10 seconds or more. Your device will restart like a normal reboot. Once it becomes active, continue using it to see if the WiFi connection still drops after some time. If it still does, then move on to the next procedure.

Reset network settings

We’ve already tried refreshing your phone’s memory to no avail so this time we’ll refresh the connection of your phone to the network. It might be the only thing that can fix the problem considering the fact that the issue started just after a firmware update. If the update was successful, then it means that your phone has a good connection prior to the update as it has to download large data for the new firmware. Follow the steps below to reset your phone’s network connection:

  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 the procedure is done successfully, the following changes will occur so make necessary changes to your phone’s network settings after that. Also, make sure to let the phone reconnect to the network again.

  • 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 WiFi connection still drops even after this, then troubleshoot the firmware instead.

Delete the system cache

Since the problem started after an update, it’s possible that it just due to some corrupt system cache. Caches files often get corrupted or become obsolete after a firmware update that’s it’s necessary at this point to wipe the cache partition so that the cache will be replaced with a new one. To do this, you have to run your phone in recovery mode and wipe the cache partition from there.

  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 three keys.
  4. An ‘Installing system update’ message will show for 30 – 60 seconds before the Android system recovery menu options appear.
  5. Press the Volume down key several times to highlight wipe cache partition.
  6. Press Power key to select.
  7. Press the Volume down key to highlight yes, them and press the Power key to select.
  8. When the wipe cache partition is complete, Reboot system now is highlighted.
  9. Press the Power key to restart the device.

After this, use the phone and continue being observant to know if the problem is fixed. If not, then move on to the last resort.

Backup important files and reset your Note 9

A master reset would be able to fix this problem and this is your last resort. If it started only after an update, then it means that it’s a software problem so don’t worry about it as it will be fixed. Before the reset however, make to backup your files and data as they will be deleted during the process especially ones that are saved in your phone’s internal storage. Once everything is set and ready, follow these steps to reset your phone…

  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.
