How To Fix The Samsung Galaxy A40 Won’t Connect To Wi-Fi Issue

Before performing the recommended troubleshooting steps for this particular problem it’s always best to make sure that the phone is running on the latest software version first. If an update is available then I suggest that you download and install it first. This will at least minimize the possibility of the problem being caused by an outdated software version.

Turn on the Wi-Fi switch of the phone

Your phone has a Wi-Fi switch which needs to be turned on so that it can connect to a Wi-Fi network. The first thing you will need to do is to make sure that this switch is on.

  • From the Home screen, swipe up on an empty spot to open the Apps tray.
  • Tap Settings – Connections – Wi-Fi.
  • Tap the Wi-Fi switch to turn on.

Check if this the Samsung Galaxy  A40 won’t connect to Wi-Fi issue still occurs.

Make sure that the router is working

There’s a possibility that the problem is caused by the router and not by your phone. Can other devices connect to the router successfully? Does the router have a setting activated ( try checking the MAC filtering setting) that is blocking your phone from connecting to it? One quick way to check if this is a router related issue is to try connecting your phone to a different Wi-Fi network then check if the issue still occurs.

Perform a soft reset

Temporary data stored by your phone that has become corrupted has the tendency of causing this problem. To fix this you will want to refresh the phone software which can be done easily by simply restarting the device.

  • Press and hold the Power and Volume down key for up to 45 seconds.
  • Wait as the device restarts.

Check if the Samsung Galaxy  A40 won’t connect to Wi-Fi issue still occurs.

Reset the phone network settings

This step is usually done whenever the phone is having a problem connecting to a data network.  The following changes will occur on your phone.

  • 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.

To reset the network settings of your device:

  • Open the Settings on your phone.
  • Now, scroll down and tap on General Management.
  • Under this menu, tap on Reset.
  • Then, tap on Reset Network Settings.
  • On the next screen, tap on RESET SETTINGS and confirm it once again.

Check if the issue still occurs.

Start the phone in Safe Mode

There are cases when an app you downloaded will cause issues on the phone when it is installed. To check if an app you downloaded is causing the problem you will have to start the phone in Safe Mode as only the pre-installed apps are allowed to run in this mode.

  • Turn the device off.
  • Press and hold the Power key past the model name screen appearing on the screen.
  • When SAMSUNG appears on the screen, release the Power key.
  • Immediately after releasing the Power key, press and hold the Volume down key.
  • Continue to hold the Volume down key until the device finishes restarting.
  • When Safe mode appears in the bottom left corner of the screen, release the Volume down key.

In case the issue does not occur in this mode then it is most likely caused by an app you installed. Find out what app this is and uninstall it.

Wipe the cache partition of the phone

There are cases when the cached data stored in the dedicated partition of the phone can become corrupted. When this happens this will usually cause certain issues to occur on the phone. To eliminate the possibility that this is what’s causing the problem you will have to wipe the cache partition of the phone from the recovery mode.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  • When the device logo screen displays, release only the Power key
  • When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  • Press the Volume down key several times key to highlight ‘wipe cache partition.’
  • Press the Power key to select.
  • Press the Volume down key to highlight ‘yes’ and press the Power key to select.
  • When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.

Check if the Samsung Galaxy  A40 won’t connect to Wi-Fi issue still occurs.

Perform a factory reset

In case the above steps fails to fix the problem then the best way to deal with this right now is to perform a factory reset. Make sure to backup your phone data before doing the reset.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  • When the device logo screen displays, release only the Power key
  • When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  • Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  • Press Power button to select.
  • Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  • Press Power button to select and start the master reset.
  • When the master reset is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.
  • With no apps installed in the phone, try to check if the issue still occurs.

If the issue still persists even after performing the steps listed above then this might already be caused by a faulty hardware component. The best thing to do right now is to bring the phone to a service center and have it checked.
