Solutions to Note10 wifi problems after Android 10 update

Because wifi problems can have varying causes, fixing your particular issue requires that you do a number of troubleshooting steps. Below are the ways to narrow down the possible causes of your problem as well as the potential solutions for it.

Is the router ok? Fix it!

Before taking your troubleshooting steps to your phone, it’s an important point in this case to make sure that your wifi network is not the cause of your wifi problem. Android updates can change some settings in your Note10 and some of those settings may suddenly become incompatible with how your router is set up. 

This does not necessarily mean that your router becomes bad. The point is to see whether or not the reason for the problem is fixable by simply doing a simple step: router restart.

Try to unplug your router from the outlet for about 12 seconds then wait for it to fully work normally again. Depending on your router, this can take about a few minutes.

Once you’ve restarted the router, connect your Note10 to it again to check for the problem.

Use another device

Another way to check if the router is allowing internet connectivity and working fine is to use another wireless device. With another phone, tablet, or laptop, check to see if you encounter the same problem. 

Troubleshoot router

If multiple devices show the same wifi issues, you’ll need the address the cause by troubleshooting the router. In most cases, rebooting a router as described above is enough but if the issue remains after that, you should consider get help from your Internet Service Provider (ISP). 

Alternatively, you can also troubleshoot the router yourself with the help of the device’s manual or documentation. You can also use Google to search for relevant router troubleshooting guides. 

Having an issue with a particular wifi network only?

If you happen to encounter wifi issues only when connecting to a particular wifi network, the issue must be outside your Note10. You’ll have to work with the wifi administrator in order to find out the root cause of the problem.

Take note of errors

Some wifi issues may include an error code or message. If you’re getting one, be sure that you write it down so you can do a quick Google search about. Errors are generally helpful in troubleshooting so your particular one may be key to solving your case.

In most instances, wifi errors are generic and may not pinpoint the exact cause of the problem. Still, it’s worth nothing whatever the error is for reference as you continue to find a solution.

Some wifi errors may be specific to a router. If you think that the error has something to do with your router, try to work with your ISP or with the router maker for a fix.

Reboot your Galaxy Note10

Whatever your Android problem is, it’s almost always a good idea to reboot your device. Your Note10 can benefit from a restart, even if it doesn’t have any issue. If you haven’t tried this yet, make sure that you do so now.

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 Bixby/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.

Disconnect from wifi networks

Wifi connection problems are sometimes fixed by doing a simple thing: forget wifi. This has been a proven wifi issue fix for years now so you’ll not lose anything if you give it a try. 

To forget a wifi network on your Note10:

  1. Open Settings app.
  2. Tap Connections.
  3. Select Wifi.
  4. Tap the Cog icon beside the wifi network your device is currently connected to.
  5. Tap Forget at the bottom.
  6. Restart your device.
  7. Reconnect to your wifi.

Clear network configuration

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.

Deal with bad system cache

Major system upgrades may sometimes cause problems for some devices. If your Galaxy Note10 wifi started having issues after Android 10 update, you must consider checking if there’s a system cache issue. This special cache is used by Android to load apps quicker. 

In some rare cases, updates may accidentally corrupt this cache, which can then result to performance and other types of issues. 

To keep the system cache in top shape:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby / Power key.
  3. When the green Android logo displays, release both keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. The Recovery screen menu will now appear. When you see this, release the buttons.
  5. Use the Volume Down button until you are highlighting ‘Wipe cache partition.’
  6. Press the Power button to select ‘Wipe cache partition.’
  7. Use Volume Down to highlight Yes.
  8. Press the Power button to confirm the action to clear the cache.
  9. Wait for a second as the system wipes the cache.
  10. Press the Power button again to reboot the device. This will return the device to the normal interface.
  11. That’s it!

Install carrier updates

Although updates may potentially cause problems, they are generally a bringer of good things. 

If your Note10 still has wifi problems after Android 10 update, make sure that you continue to install updates as they may contain fixes for known or identified bugs. For network problems, carriers will roll out solutions to identified bugs via updates only so be sure to keep your Note10 updated.

If you have an unlocked, global Samsung Galaxy Note10, you can manually check for updates under Settings > Software update > Download and install.

Check for broken apps

Not all apps are created equal. Because developing and maintaining apps is costly, not all developers can keep their products in top shape all the time. If your wifi started acting up after an update and no suggestions above has helped so far, your next step is to check for bad third party apps. 

First you want to make sure that all your apps are fully updated. You can do this by going to your Play Store app. 

To check for Play Store app updates on your Galaxy Note10:

  1. Open Play Store app.
  2. Tap More settings icon at the upper left (three-horizontal lines).
  3. Tap My apps & games.
  4. Tap Update or Update All.

If you are on Cellular Data connection, we suggest that you update via wifi only to avoid additional charges. Here’s how:

  1. Open Play Store app.
  2. Tap More settings icon at the upper left (three-horizontal lines).
  3. Tap Settings.
  4. Tap App download preference. 
  5. Select Over wifi only (select Over any network if you don’t have wifi).
  6. Tap Done.

Make sure to also keep your apps updated all the time by enabling auto-update option.

  1. Tap Auto-update apps.
  2. Tap Over wifi only (select Over any network if you don’t have wifi).
  3. Tap Done.

If you have apps taken from outside the Play Store, you may need to update them by installing an updated APK. Work with the app developer to know exactly what to do.

Restart to Safe Mode

An effective way to check for a bad installed app in your Note10 is by using the utility tool called Safe Mode. By restarting your Note10 to safe mode, all third party apps will be blocked (greyed out). If your wifi works normally only when your Note10 is on Safe Mode, you can bet a bad third party app is to blame.

To boot your 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.

Restore software to defaults (factory reset)

If your Note10 continue to have wifi problems after Android 10 update, the final solution that you can try in this situation is factory reset. This is usually effective in fixing issues with software-related causes. 

Factory reset will erase your data such as photos, videos, contacts, documents, etc. Be sure to back them up ahead of time.

Below are the two ways to factory reset your Galaxy Note10:

Method 1: How to hard reset on Samsung Galaxy Note10 via Settings Menu

This is the easiest way to wipe your Galaxy Note10. all you have to do is to go under Settings menu and follow the steps below. We recommend this method if you have no trouble going under Settings.

  1. Create a backup of your personal data and remove your Google account.
  2. Open Settings app.
  3. Scroll to and tap General management.
  4. Tap Reset.
  5. Select Factory data reset from the given options.
  6. Read the information then tap Reset to continue.
  7. Tap Delete All to confirm action.

Method 2: How to hard reset on Samsung Galaxy Note10 using hardware buttons

If your case is that the phone is not booting up, or it boots but Settings menu is inaccessible, this method can be helpful. First, you need to boot the device to Recovery Mode. Once you successfully access Recovery, that’s the time that you begin proper master reset procedure. It may take some tries for you before you can access Recovery so be patient and simply try again.

  1. If possible, create a backup of your personal data ahead of time. If your problem prevents you from doing that, then simply skip this step.
  2. Also, you want to make sure that you remove your Google account. If your problem prevents you from doing that, then simply skip this step.
  3. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
  4. Press and hold the Volume Up key and the Bixby / Power key.
  5. When the green Android logo displays, release both keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  6. The Recovery screen menu will now appear. When you see this, release the buttons.
  7. Use the Volume Down button until you are highlighting ‘Wipe data/factory reset.’
  8. Press the Power button to select ‘Wipe data/factory reset.’
  9. Use Volume Down to highlight Yes.
  10. Press the Power button to confirm factory reset.
  11. Follow the rest of the instructions to finish the task.
