How To Fix Samsung Galaxy A9 Not Connecting To Wi-Fi While Other Devices Are Also Connected

Problem: PROBLEM CONNECTING TO WIFI WHILST OTHER DEVICES CONNECTED TOO – ONLY AFTER TWO WEEKS OF USE….. ANDROID VERSION 8.0.0. This is my second new Galaxy A9 phone both with EXACTLY the same problem.  Phone connects to WIFI without any problems for approximately two weeks. During this time I can browse the internet from either my laptop or phone with both connected to the same WIFI connection.  After two week, if both are connected over WIFI neither will connect to the internet, if I switch WIFI off on Laptop then phone will connect, if I switch WIFI off on phone then laptop will connect. If I switch WIFI off on phone and then switch my old IPhone on, both laptop and Iphone will connect over WIFI and if I switch WIFI off on laptop and try to connect to the internet whilst IPhone and A5 are both connected to WIFI  neither will connect again. So summary is Galaxy A9 will not connect to internet over WIFI whilst another device is also connecting to internet over same WIFI, but this only starts after about two weeks of using the phone! During those two weeks the phone did auto update some apps, but I switched all auto updates off about 5 days ago (when I found out how), and this only starting happening today, so I do not see the link with this.  On the first phone I restarted it in safe mode and same problem and I reset it to factory defaults, it seemed to work after factory default reset, but I didn’t want to risk it failing again outside of the return period, so returned to store and swapped for another new one. I now feel the only option is to return again and go back to iphone but they are too expensive for me now 🙁 Help Please!!! Ps: I have restarted router and deleted WIFI connections and recreated on all devices to no avail and I do not think this would fix it anyway, it is definitely down the A9 connecting when another device is connected…..

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 then I suggest that you download and install it first.

What you should do in this case is to verify if the problem occurs while the phone is connected to a different Wi-Fi network. If the issue does not occur then the problem could be caused by a wrong setting in your wireless router. You will need to restart your router then check if it has the correct settings. You will need to refer to the router manual on the proper procedure on how to access its settings.

In case the issue persists even when the phone connects to a different Wi-Fi network then you should proceed with the additional troubleshooting steps listed below.

Perform a soft reset

The first thing that you will need to do in this case is 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 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.
