How to fix Galaxy M20 wifi not working | wifi won’t connect

Troubleshooting wifi issues is usually easy and fixable on an end user’s level. If your Galaxy M20 wifi is not working, find out what you can do about it.

Galaxy M20 wifi not working solution #1: Restart router

Whenever you encounter wifi issues, one of the basic things to do immediately is to restart the router. If you have a problem with your home wifi, we suggest that this suggestion should be done first. Simply turn off the router by unplugging it from the wall outlet for 10 seconds. Afterwards, wait for the connection to be reestablished and see if it works.

If you don’t have wifi connectivity at home or if you have to access to the router, continue with the next steps below.

Galaxy M20 wifi not working solution #2: Confirm wifi is working

Another basic troubleshooting step is to determine if it’s a wifi issue. Are there other wireless devices that you know that are connected to the same wifi? Are they having wifi connectivity issues similar to what you have? These are some of questions that you should ask to know if the cause of the problem is coming from the router, or from your own device. If other devices are having the same issue, then there’s probably a router issue that must be resolved. Make sure to let the wifi administrator know of your issue so they can look into it.

If other devices work on the same network without problems, it’s possible that your device may be blocked or there’s only a limited number of users allowed to connect. This usually happens on wifi networks that serve the public. Unfortunately, what you can do is to simply wait until there’s an available connection slot for you, or you may have to talk to the wifi administrator to unblock you. If you’re on a private wifi, talk to the person in charge and see if they can help you connect.

Your aim at this stage is to know where the issue is coming from. If the wifi you’re trying to connect to works on other devices, it’s either you’re being blocked or there’s a problem with your Galaxy M20.  

Galaxy M20 wifi not working solution #3: Check for errors

In some cases where wifi is not working, there may be errors that can potentially help you narrow down the causes. Make sure to take note of any error message or code that shows up whenever wifi stops working. Then, do a quick Google search about it to see if there’s an online solution for it.

Galaxy M20 wifi not working solution #4: Do soft reboot

Sometimes, restarting the system helps. Make sure that you perform a soft reset to clear the RAM and refresh the device’s software in general. This should clear the system and possibly get rid of the bug as well. To do that, simply press and hold the Power and Volume Down buttons for about 10 seconds. Once the phone has restarted, release the buttons. This is usually effective in clearing bugs that developed when a system is left running for some time. We suggest that you restart your Galaxy M20 using this method at least once a week to lessen the chances of bugs.

For some Galaxy M20, there may be a slightly different way to arrive at the same method. Here’s how:

  1. Press and hold the Power + Volume Down buttons for approximately 10 seconds or until the device power cycles. Allow several seconds for the Maintenance Boot Mode screen to appear.
  2. From the Maintenance Boot Mode screen, select Normal Boot. You can use the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Wait for up to 90 seconds for the reset to complete.

Galaxy M20 wifi not working solution #5: Clear cache partition

Android depends on a set of temporary files called system cache to load apps quickly. If this cache gets corrupted or outdated, a device may suddenly lag, freeze, or show signs of slow performance. At other times, uncommon glitches may occur as well as overall performance of the system may also be affected. To ensure that your S10 has good system cache, we suggest that you clear it once every few months. Here’s how to do it:

  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 M20 wifi not working solution #6: Reconnect to wifi

Another basic troubleshooting step that you can do in this case is to forget your wifi. This has proven effective in fixing troubles with wifi. What it does is refresh the wifi credentials saved on your phone. By disconnecting your wifi, you are forcing the device to save updated wifi username, password, and configuration.

In order to forget your wifi network:

  1. Pull down the notification bar from the top of the screen.
  2. Tap and hold the wifi icon.
  3. Tap the name of your wifi network (the one you’re having a problem with).
  4. Tap FORGET button.
  5. Restart your phone.
  6. Reconnect to your wifi and see it it’s working now.

Galaxy M20 wifi not working solution #7: Reset network settings

Another important troubleshooting step that you want to do in this case is to reset all network settings. This troubleshooting step will clear all non-default network settings and hopefully clear potential bugs. If you haven’t tried this yet at this stage, here’s how:

  1. Open Settings app.
  2. Tap General management.
  3. Tap Reset.
  4. Tap Reset network settings.
  5. Tap Reset settings to confirm.

Galaxy M20 wifi not working solution #8: Check for bad apps

Sometimes, a poorly coded app or malware may interfere with Android and cause problems. To check if you have a third party app problem, restart the phone to safe mode. On safe mode, all third party apps, the ones you downloaded that did not come with the original software, will be suspended. So, if the problem comes from one of them, the problem you’re experiencing right now will not be available on safe mode. To boot the phone to safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the screen with the device name.
  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. Check for the problem. If wifi works properly and won’t disconnect or show error, you have a bad app problem.

If your Galaxy M20 wifi is still not working when you restart the device back to normal mode, you should investigate further. To identify the culprit, you can use the method of elimination. 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 M20 is still problematic, repeat steps 1-4.

Galaxy M20 wifi not working solution #9: Factory reset

The final device troubleshooting that you can try is factory reset. This will help if there’s an unknown software bug that causes the problem. Make sure to create a backup of your personal data ahead of time.

Below are the two ways to factory reset your Galaxy M20 :

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.
