How To Fix The Vivo Y91 Won’t Connect To Wi-Fi Issue

Before performing any of the recommended troubleshooting steps for this particular 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. This minimizes the possibility of the problem being caused by an old software version.

Don’t forget to turn on the Wi-Fi switch

Your phone will have a Wi-Fi switch which will have to be turned on in order for it to connect to a Wi-Fi network. There are cases when the phone owner will forget to turn on the Wi-Fi switch making it seem that there is a Wi-Fi problem. What you will want to do first in this case is to make sure that the Wi-Fi of the phone is switched on.

  • Select Settings
  • Select Wireless & networks
  • Select Wi-Fi
  • Turn on Wi-Fi

Try to check if the phone can connect to the Wi-Fi network.

Check if the problem is caused by the router

Sometimes the problem is not caused by the phone but by the router your phone is trying to connect to. Your should eliminate the router as a possible cause of the problem. Can other devices connect to the router successfully? Does the router have a setting activated (MAC filtering) 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. If it doesn’t then it’s very likely that the problem is caused by the router.

Perform a soft reset

There are cases when corrupt temporary data can cause this problem. What you will want to do if this is what’s causing the problem is to refresh the phone software which can be done easily by simply restarting the device. Although this is usually done on an unresponsive device it should also work in this case.

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

Check if the Vivo Y91 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:

  • Turn on the phone by pressing the Power key for a few moments
  • Choose Settings
  • Tap More Settings.
  • Tap Backup and Reset.
  • Select Reset Network Settings.

Check if the issue still occurs.

Start the phone in Safe Mode

Sometimes an app you downloaded from the Google Play Store  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 off the phone
  • Press power button to turn on phone then long press on the volume down key when the Vivo logo appears
  • The phone should now boot in Safe Mode.

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 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.

  • Press and hold the Volume Down + Power key together for a short while.
  • Release all buttons when Fastboot Mode appears.
  • In this mode select “Recovery”. Use Volume Down to navigate and the Power key to confirm that.
  • Press the volume key to highlight the Wipe cache option then the power key to select it
  • Use the volume keys to go to “reboot system now” and press the power key.

Check if the issue still occurs.
