What to do if Galaxy Note5 disconnects from wifi immediately [troubleshooting guide]

One of the common connection problems for Galaxy devices is wifi-related. Today’s troubleshooting article will address a #GalaxyNote5 problem. Basically, the issue is that wifi seems to cut out at random or almost immediately after establishing a connection. Such an issue can be due to a bad app, software bug, router or ISP-side issue, or hardware malfunction. This guide will walk you through the steps on how to narrow down the cause as well as how to resolve it.

Today’s problem: Galaxy Note5 disconnecting from wifi immediately, keeps dropping on its own

My Samsung Note5 disconnects from wifi immediately now. My laptop still connects fine, as does my tv. It’s been a month with people trying to figure out what’s going on. I’m up to date on all updates for my phone, the last one listed was in January. I’ve done a soft reboot of the phone to no avail. I was told to get another router but that may cost me a hundred I don’t have for a 1gig router. What can I do, I am almost out of data from this shit happening? No one seems to be able to help and tell me buy a new phone and new router and I might get Internet back, or it might happen again. — Chris

Solution: Hi Chris. If other wireless devices can connect to your home wifi network without problems and don’t have the issue you’re having on your Note5, that’s probably because the issue lies on your phone. You must focus your troubleshooting on your phone to determine what’s wrong with it. Below are the things that you can try.

Solution #1: Verify your Note5 is able to connect to other networks fine

Because you’ve already tried soft reboot before you contact us, the next good thing to do right now is to check how your Note5 works when connected to other wifi networks. You may want to go to your public library or to your nearby Starbucks and see how it works. If your Note5 still drops the connection right away, that’s another strong indication that there’s an issue with your phone. It can be a software glitch or a sign of a malfunctioning hardware.


If your Note5 works properly on another wifi network, it’s possible that there’s a configuration issue on your home wifi, or something triggers your phone to disconnect when near using your own wifi.

Solution #2: Forget saved networks

Old wifi settings may sometimes cause problems in terms of connection or internet connection speed. To minimize the chance of this from happening, make sure that you disconnect your Note5 from your wifi network and wipe it from the device. Here’s how to do that:

  1. Open Settings app.
  2. Tap Connections.
  3. Tap WiFi.
  4. Select your home wifi.
  5. Tap Forget.
  6. Restart your Note5.
  7. Sign back in to your wifi network and check for the problem.

Solution #3: Clear cache partition

Android uses a special cache called system cache everytime it loads an app. At times, this system cache gets corrupted or outdated, resulting to all sorts of issues. To lessen the chance of problems including the ones similar to what you’re experiencing, you want to regularly refresh the system cache. Here’s how to do that:

  1. Turn off your Samsung Galaxy Note 5 completely.
  2. Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  3. Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  4. Once the Android logo shows, release both the Volume Up and Home buttons.
  5. The notice ‘Installing system update’ will show on the screen for 30 to 60 seconds before the Android system recovery screen is shown with its options.
  6. Use the Volume Down key to highlight the option ‘wipe cache partition’ and press the Power key to select it.
  7. When the process is complete, use the Volume Down key to highlight the option ‘Reboot system now’ and hit the Power key to restart the phone.
  8. The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

Solution #4: Install system updates

We know your Note5 is up-to-date according to you but for the sake of other users who may not have done so, make sure that your device runs the latest available Android update. A lot of network-related issues are fixed by this simple maintenance tip. By default, carrier-branded smartphones are set to automatically download and install system updates but if you change this setting before, be sure that you manually check for updates now.

You can do that by going under Settings > Software update.

Note: If your Note5 is not originally built for the network you’re currently in, it won’t be able to download Android update. So, for example, if you have an AT&T Note5 but you’re now using it with a T-Mobile network, it won’t be able to receive over-the-air update at all. Some devices may still be able to get updates via Samsung Smart Switch though so be sure to try that.

Solution #5: Observe in safe mode

Try to run your Note5 to safe mode and see how its wifi works. In this mode, all third party apps and services won’t be running (they’ll be blocked) so it should help you determine if there’s an app that interferes with Android.

To restart your Note5 to safe mode:

  1. Turn off your Note5. If you can’t turn it off normally, let the phone drain its battery until it turns itself off.
  2. With your Note5 off, 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.
  8. Connect to your home wifi again and check for the problem. Let your phone run for some time to see if wifi will drop later on.

If wifi works and won’t drop at all, that means you have an app issue. Safe mode won’t pinpoint the exact app though so you have to do the steps below to know which app is problematic:

  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 Note5 wifi is still problematic, repeat steps 1-4.

Solution #6: Reset network settings

One of the most effective ways to fix any internet connection issue on a Samsung Galaxy device is by wiping all network settings. If you have no idea how to do that, follow these steps:

  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.

Solution #7: Factory reset

As a final drastic solution, you can try to factory reset your device to restore all software settings to their defaults. If the reason for your wifi trouble is app- or software-related, factory reset should fix it. Otherwise, you should contact your internet service provider (the company that provides home internet connection and router) for help.

To factory reset your Note5:

  1. Turn off your Samsung Galaxy Note 5 completely.
  2. Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  3. Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  4. Once the Android logo shows, release both the Volume Up and Home buttons.
  5. The notice ‘Installing system update’ will show on the screen for 30 to 60 seconds before the Android system recovery screen is shown with its options.
  6. Use the Volume Down key to highlight the option ‘Yes — delete all user data’ and press the Power key to select it.
  7. When the process is complete, use the Volume Down key to highlight the option ‘Reboot system now’ and hit the Power key to restart the phone.
  8. The reboot may take a little longer to complete but don’t worry and wait for the device to become active.
  9. Let your Note5 run for an hour and check for the problem.

Solution #8: Talk to your ISP

If your Note5 works with other wifi networks but encounters a problem of constantly disconnecting when on your own wifi network, you should let your Internet Service Provider handle the case for your. It’s possible that there’s a certain setting on the router that needs to be changed or configured. There’s also a chance that the problem may lie within the router itself.
