Disconnect All Devices

There is something called an IP conflict when one or more users share The same  IP address  to connect to the same  network

This causes overlap in data communications. To fix this:

  • Disconnect all connected devices from the modem to the cell phone, tablet and PC.
  • Wait one minute after unplugging the modem.
  • Plug the modem back in and connect only one device to the modem.
  • When you see this you are successfully connected. You can also connect other devices.

Power Cycle Solution

Power cycling refers to the loss of a full charge or power to the device. This something can work as a miracle and fix the problem with Wi-Fi within a minute. If your device has a removable battery, remove the battery from the device, but make sure the phone is not connected to any power source before that. place the battery in a separate place for 1-2 minutes and then put it back in place. Now turn on the device to see if the problem is now fixed.

But if your device has a non-removable battery, there is another way to perform a power cycling solution and that is to long press the power button for 10-20 seconds.

Check Third Party Apps

Sometimes, it could be any third-party app that is creating the whole problem. If you can remember the last third-party app that you installed after the problem actually started, simply uninstall the app. However, if you are not sure whether this app is the main culprit or not, you can start the device in safe mode, which will disable all third-party apps, and if the problem does not occur in this mode, make sure that it is not something else. So, try to recognize the app and uninstall it. Or you can perform a factory reset.

If Android Wi-Fi still won’t turn on, start your device in Safe mode

  • Press and hold the power button for a few seconds which will bring you several options.
  • Then tap and hold power off until you are prompted to confirm entering safe mode.
  • Press OK and your phone will restart in safe mode.

Reset to Factory Settings

Set route in this direction

  • Setting
  • Accounts tab
  • Backup and reset
  • Factory data reset

Before performing this step, back up your important data, as a factory reset erases all data and brings the phone back to the way it was when you first got it. There are several ways to make a backup of your phone. First, follow the steps below to create a backup.

  • One of the best options is to use Samsung’s own Kies software, which we normally use to update the software of our Galaxy devices.
  • The second way to create a backup of the device is through the Google account. Settings> General> go to Backup & Reset and it offers two options; these are back up my data and automatic restores. Make sure it is enabled by checking the checkbox next to these options; it automatically backs up details such as Wi-Fi password, app data, Google settings and bookmarks to Google server.
  • Another way to back up your data is to use the Samsung account. To do this, go to App> Settings> User & backup> Account and check if you are signed in to your Samsung account. If the option is set to on, it will synchronize contacts, calendar and internet settings to the Samsung account.

    1. Hello Rafet, if your phone does not see the WI-FI network, the WI-FI option of the modem you want to connect to may be turned off, check that the WI-FI option is active. Also try to connect again by changing the name and password of the modem you want to connect to.
