How To Fix Samsung Galaxy A9 Keeps On Disconnecting From Wi-Fi

Problem: Hello! I have a Samsung Galaxy A9, which spontaneously and frequently disconnects from my home wifi. This is definitely an issue with the phone, as no such connection issues are present on any other household devices. What happens is, when I’m using an app that requires internet, it will spontaneously stop loading, and moments later an icon will appear at the top bar that signals that there is no internet connection. I turn off the wifi on my phone and reconnect it, then a few seconds later it’s working again. However it does this so frequently, and really spontaneously, that it’s really burdensome. I’ve tried wiping the cache partition, which solved nothing. I’ve also tried ‘forgetting’ my home wifi, and inputting the details again to reset it, which also solved nothing. I’m not sure what else I can do about it. If you can help, I would really appreciate it!

Solution: Before performing any troubleshooting steps on this device it’s best to make sure that it is running on the latest software version. If an update is available I suggest that you download and install it first.

The first thing you should do in this case is to check if the problem is caused by the router. Connect the phone to a different Wi-Fi network then check if the issue still occurs. If it doesn’t then you should try to troubleshoot your router by restarting it then checking if it is caused by a setting issue. For this you will need to consult your router manual.

In case the issue still persists then you will have to proceed with the troubleshooting steps listed below.

Perform a soft reset

Try to refresh the phone software. A soft reset is usually performed when a device is unresponsive but should also work in this case as it will refresh the phone software. To do this step just hold the power button and the volume-down button for around 10 seconds. Let go of the buttons once you feel the device vibrate and see the Samsung Galaxy A9 logo on the screen. Your phone will then reboot, and hopefully, start working properly once again.

Check if the issue still occurs.

Reset network settings

This will reset all data connection back to their default factory settings.

  • From the Home screen, swipe up on an empty spot to open the Apps tray.
  • Tap Settings > General Management > Reset > Reset network settings.
  • If you have set up a PIN, enter it.
  • Tap RESET SETTINGS. Once complete, a confirmation window will appear

Check if the issue still occurs.

Check if the problem occurs in Safe Mode

Try to check if an app you downloaded is causing this problem is by starting the phone in Safe Mode. When your phone is started in this mode only the pre-installed apps are allowed to run making it easier to determine if an app you downloaded is the culprit.

  • With the phone turned on press the turned on start pressing the Power button.
  • If the menu pops up tap Power off and tap the option to open Safe mode.
  • Wait for a few moments.
  • The device is now booted in Safe Mode

In case the issue does not occur in this mode then you should find out what app is causing the problem then uninstall it.

Wipe the cache partition

Your phone will save temporary data in a certain area of its storage space. This data can be accessed easily by the device making it perform better. This temporary data however can become corrupted and can cause certain issues to occur on the device. To check if this is what’s causing the problem you will have to wipe the cache partition of your phone.

  • Turn off your device.
  • Now Press and hold the Bixby, Volume Up and Power buttons for few secs.
  • After you see the Android Logo is displayed, release the Power and Bixby button, but keep holding the Volume Up button until the Recovery Mode screen shows up
  • Now you can see the Android System Recovery Menu option.
  • Use volume keys to highlight wipe cache partition and use the power button to select it
  • Confirm by selecting yes option

Try to check if the issue still occurs.

Perform a factory reset

One last troubleshooting step to consider is a factory reset. This will revert your phone back to its original factory condition. Make sure to backup your phone data as it will be erased in the process.

  • Go to  settings of your phone.
  • Now Scroll down and select General management option
  • Tap on Reset option
  • Choose  Factory data reset
  • Select the option ‘Erase everything’ and then wait till your device gets rebooted with the factory settings.

Once the reset is complete do not install any apps in your phone just yet. Try to check first if the issue still occurs. In case the problem persists then you will have to bring the phone to a service center and have it checked as this could already be caused by a faulty hardware component.
