Why your Galaxy Note10 has wifi issues and how to fix them

There’s no simple explanation why a device like your Galaxy Note10 may encounter wifi issues. In most cases, the cause can be simple but at other times, it may be a  combination of factors. To fix any particular wifi trouble you’re having, you’ll need to do a number of troubleshooting steps in order to identify the source of an error or problem. This guide will help you do that. Follow our suggestions below in the order presented.

Galaxy Note10 wifi issues fix #1: Confirm router or network is working

If you have wifi issues on your Galaxy Note10, the first troubleshooting step that you want to do is to check if the problem comes from the router or particular wifi network you’re dealing with. If you have access to the router, the first thing that you want to do is to powercycle or restart it. Just unplug the router from the wall outlet for a few moments before starting it back up. In most cases, this is enough to fix wifi problems. If you have no idea how to troubleshoot the router further, contact your Internet Service Provider.

Alternatively, you can try to confirm whether it’s a wifi issue by connecting your Galaxy Note10 to another router. If wifi works on the second network, then that means there’s no problem with your Note10 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.

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

If you have no access to the router and you’re only having trouble connecting to a particular network, talk to the network administrator for help.

Galaxy Note10 wifi issues fix #2: Check for errors

If you’re positive that the router is working or there’s no issue at all with the wifi network, then your focus should be on troubleshooting your Note10. If your Galaxy Note10 has an error code or message, you can do a quick Google search about it and see if there’s an online solution to try. 

Galaxy Note10 wifi issues fix #3: Restart device

Fixing Galaxy Note10 wifi issues is often simple and one of the ways to do it is by restarting the device. If your Galaxy Note 10 has wifi issues, forcing it to restart is an effective way to fix it. If you haven’t tried this yet, be sure that you do it this time. Try restarting it normally first by pressing the Power button to access the boot menu. Then, select Restart option and see if that works.

Another way to restart the device is by pressing and holding the Volume Down button and the Power key at the same time for 10 seconds or until the device’s screen turns on. This simulates the effect of having disconnected the battery from the device. If this works, this may unlock the device.

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. If nothing changed though, proceed to the next suggestions.

Rebooting your device regularly at least once every week can be beneficial. If you tend to forget things, we suggest that you configure your phone to reboot on its own. You can schedule it to do this task by doing these steps:

  1. Open Settings app.
  2. Tap Device Care.
  3. Tap the 3-dot at the top.
  4. Select Auto restart.

Galaxy Note10 wifi issues fix #4: Forget wifi

Another simple solution that you can try in this case is to disconnect and 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.

Galaxy Note10 wifi issues fix #5: 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 Galaxy Note10 and check for the problem.

Galaxy Note10 wifi issues fix #6: Refresh system cache

If your Galaxy Note10 wifi issues started after the system has been updated, there may be a problem with the system cache.  To ensure that your Galaxy Note10 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.

Galaxy Note10 wifi issues fix #7: Restart to Safe Mode

Causes of wifi problems can vary a lot. One other possible cause in this situation is a bad third party app. Sometimes, poorly coded apps may interfere with Android and cause problems. At other times, malware or bad apps are intentionally designed to cause problems or prevent certain functions to not work. If you noticed that wifi functionality started to act erratically after installing a new app, erasing that app might help. If you can not recall which app you installed, or if you suspect that one of the apps is to blame, try to restart your device to safe mode. On SAfe Mode, all third party apps are suspended and can’t run. If you can’t remember the app, try to restart the device to safe mode and see what happens. So, if the problem goes away on safe mode only, that’s a clear indication that the cause is a bad third party app. To boot the device to safe mode:

  1. Press and hold the Power button until the Power off window appears then release.
  2. Touch and hold Power off until the Safe mode prompt appears then release.
  3. To confirm, tap Safe mode.
  4. The process may take up to 30 seconds to complete.
  5. Upon reboot, “Safe mode” appears in the lower-left of the home screen.

Remember that third-party applications are disabled in this mode so what you can use are pre-installed apps. If Galaxy Note10 wifi works normally on safe mode only, that means that the problem is due to a bad app. Uninstall the app you recently installed and see if that will fix it. If the problem remains, use the process of elimination to identify the rogue app. Here’s how:

  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 Galaxy Note10 still won’t turn on normally (but works on safe mode), repeat steps 1-4.

Galaxy Note10 wifi issues fix #8: Install updates

Keeping the software environment of your Galaxy Note10 up-to-date is important. If you continue to have Galaxy Note10 wifi issues at the moment, make sure that you have the software and apps running their most recent version. Not only do updates bring cosmetic changes but they also fix known bugs. Although not generally known by many Android users, installing updates sometimes also bring needed fixes for known bugs. Make sure that you don’t delay the installation of any system or app updates. By default, your phone should notify you of any available updates but in case you turn this mechanism off, it’s high time that you manually check for them.

To check for Android or system update:

  1. Open Settings app.
  2. Tap Software update.
  3. Tap Download and install.
  4. Wait for the device to check for updates.
  5. Install the update. If there’s no new update, your phone should tell you so.

For carrier-branded Galaxy Note10 devices, or those that were provided by your carrier, there may not be an option to manually check for updates. All you have to do is to simply confirm if there’s a notification for an update and allow update installation.

To check for app updates:

  1. Open Play Store app.
  2. Tap More settings icon (at the upper left).
  3. Tap My apps & games.
  4. Tap Update all button.
