How to troubleshoot Galaxy S7 Edge that keeps disconnecting from Wifi

Problem: Galaxy S7 Edge keeps on disconnecting from Wi-Fi then trying to connect, connects then disconnects and so on. This has only happened since the nougat system update. Is OK at home but lots of places which used to be fine are now not. Tried installing different apps but nothing is working.

Solution: If this problem started shortly after the update, then it’s very much possible that some of the files that system is using got corrupted or may now be obsolete since an update from Marshmallow to Nougat is a major one. Big updates may change the phone’s system architecture and it may need to create new caches and other files to run properly. While some files get automatically replaced during updates. There are those that aren’t and these might be the reason why your phone keeps getting disconnected from the Wi-Fi hotspot it’s connected to.

Step 1: Try to boot it in Safe mode and observe if the phone still disconnects

Booting your phone up in safe mode will temporarily disable all third-party apps so if one of them is causing the problem, your phone’s Wi-Fi connection may work without any issues while it’s in this mode. You to remember though that this method won’t fix the problem but will give you an idea what the cause is. So, if your phone is able to connect while in this state, then there is an app that caused the problem. Here’s how you start your phone up safe mode:

  1. Press and hold the Power key.
  2. As soon as you can see the ‘Samsung Galaxy S7 EDGE’ on the screen, release the Power key and immediately hold the Volume Down key.
  3. Continue holding the Volume Down button until the device finishes rebooting.
  4. You may release it when you can see ‘Safe mode’ in the bottom left corner of the screen.

While in this state, try connecting the device to your home Wi-Fi and see if it can connect. If the phone still disconnects randomly or frequently, then you might be facing a more serious firmware issue. However, if the problem got fixed, then our suspicion that one or some of the apps you installed is causing the problem. You have to find that app and try to update it first, then move on to resetting it by clearing the cache and data and uninstall it if the problem remains after doing the previous steps. Here’s how you do those things…

How to update apps install on your Galaxy S7 Edge

  1. From any Home screen, tap the Apps icon.
  2. Tap Play Store.
  3. Tap the Menu key and then tap My Apps. To keep your apps automatically updated, tap the Menu key, tap Settings, and then tap Auto-update apps to select the check box.
  4. Choose one of the following options:
    • Tap Update [xx] to update all applications with updates available.

Step 2: Delete the System Cache Partition

For the device that has been recently updated, it is not far that caches will become obsolete or corrupted. So, at this moment we will have to verify what really triggered the problem on your phone by deleting the old system caches. But since we cannot erase the caches one by one all we need to do is to clear the cache directory so that in the next boot up all of it will be replaced by new ones.

Please note you only have to do this if the Wi-fi still gets disconnected while in safe mode or if the problem remained after doing the previous step. Here’s how you boot your phone up in Recovery mode and wipe the cache partition:

  1. Turn off the phone.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished wiping the cache partition. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

Once the phone has successfully rebooted, try to connect to your Wi-Fi hotspot and observe if it still gets disconnected. If the problem still persists, then try doing the next step prior to resetting your phone.

Step 3: Reset all network settings

Since your phone is obviously having problems with its connection, we have to reset all its network settings to bring it back to out of box factory defaults. If the problem is caused by incorrect settings, then this step will surely fix the problem. But before doing so, let me just tell you that this will do the following:

  • 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.

And the following connection status will be brought back to their defaults which are…

  • Airplane mode: OFF
  • Bluetooth: OFF
  • Data roaming: OFF
  • Mobile hotspot: OFF
  • VPN: OFF
  • Mobile data: ON
  • Wi-Fi: OFF

Now, here’s how you reset all network settings of your phone…

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > 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.

After this, turn the Wi-Fi connection back on and let your device scan for available hotspots, then reconnect to the network you used to connect and continue your observation. If the problem remained, then it’s time to reset your device.

Step 4: Backup your files and reset your Galaxy S7 Edge

The purpose of doing this procedure is to bring back the device to its factory default settings and to eliminate any bugs that your phone might have acquired during and after the upgrade. But the downside for this method is that the files and data you stored in your phone’s internal storage will be wiped out. So, prior to the reset, we suggest that you backup all your important files by transferring it to the SD card or computer. After which, disable the Factory Reset Protection (FRP) so that you won’t be locked out of your device after the reset.

How to disable FRP on your Galaxy S7 Edge

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Cloud and accounts.
  4. Tap Accounts.
  5. Tap Google.
  6. Tap your Google ID email address. If you have multiple accounts setup, you will need to repeat these steps for each account.
  7. Tap Menu.
  8. Tap Remove account.
  9. Tap REMOVE ACCOUNT.
