The reasons why your Android Wi-Fi won’t turn on

If you are using an android smartphone, it may sometimes won’t turn on for several reasons.

The most common reason could be low memory space in your device.

Check the RAM manager and see if the free memory is less than 45 MB. If it is, the Wi-Fi won’t turn on normally.

The other reason may be the fact that power saving mode is on.

Solutions for “Wi-Fi won’t turn on” problem


Clear memory

To solve the problem, go to RAM manager. Then perform a level 1 clear of the memory.

If the problem is not solved, then perform level 2 clear of the memory.

After performing this you will see that almost 800 MB of memory will be free. Level 2 clear of the memory

helped many users to fix the issue.

  • Level 1 clears all the apps that are running
  • Level 2 clears your hidden programs that are running in the background.



Reboot The Phone

Try rebooting the device once to see if the issue related to Wi-fi is fixed. To do so:

  • Turn on the Airplane mode on your device by pulling down the notification area.
  • Next power off the device completely.
  • Now pull out the battery and keep the phone in this condition for 5 minutes.
  • Press down the power button for a minute without inserting the battery.
  • Re-insert the battery and then power on the device by pressing the power button.
  • Now check if the problem is resolved.

Reboot phone



Turn WIFI Power Saving Mode Off

One of the main reasons you are having a problem with your wifi on your Samsung Galaxy /Android,

is due to power saving mode.

To turn this mode off navigate to:

  • Dialer
  • dial: *#0011#
  • This will open up the service mode
  • Press the menu key
  • Click WIFI
  • By default, the power-saving mode remains on in some of the Galaxy devices, switch them off.


Check Airplane mode

This is advised to check once in case you have enabled these settings in your Android device and if you find that the Airplane mode is on, disable that option and check if the Wi-Fi won’t turn on the issue is resolved then. However, when this Airplane mode is set to on, not just Wi-Fi rather you will start facing several other issues as well.

Update Firmware and Change Channel of Router

Navigate to your Router back office

  • Linksys –
  • 3Com –
  • D-Link –
  • Belkin –
  • Netgear –


Normally the username is the admin, and the password is password.

After logging in, navigate to wireless settings and set the Channel that is best for you, you can know by using wifi analyzer on your android, or you can select a Channel between 4-

These channels tend to perform best in most places.

After changing your channel, navigate to the Advanced tab and Click on Firmware Upgrade.

Update firmware



Disconnect All Devices

There is something call IP conflict, where one or more users are sharing the

same IP address to connect to the same network.IP address to connect to the same network.

This causes an overlap in data communication. To fix this:

  • Disconnect all connected devices to the router, mobiles, tablets, and PC.
  • Plug out the Router for one minute.
  • Plug in the router back and connect only one device to the router.
  • When you see that, you are connected successfully. Connect the rest of the devices.
Disconnect all devices



Power Cycle Solution

Power cycle refers to removing the full charge or power from the device. This might something work as a miracle and can solve the Wi-Fi related issue in just a minute. If your device has a removable battery, just pull out the battery from the device but ensure the phone is not connected to any power source before that. locate the battery separately in a place for 1-2 minutes and then reinsert it back. Now turn on the device to see if the issue is fixed now.

But in case your device has a non-removable battery, there is another way to perform a power cycle solution and this is by long pressing on the power button around 10-20 seconds.



Check The Third Party Apps

Sometimes it might be any third party application which is creating the whole issue. If you can remember the last third-party app you installed after which the problem actually started, just uninstall the app and you will be good to go. But in case you are not sure if this app is the actual culprit, booting the device in safe mode is recommended that will disable all the third party apps and if the problem does not arise in this mode, then be sure that this is nothing but a third party application to create this Wi-Fi issue. So, try recognizing the app and uninstall it. Or else you can perform a factory reset.

To boot in safe mode,

  • Press and hold the power button for few seconds which will bring you several options.
  • Next, tap and hold down the power off option till you are asked to confirm to enter into safe mode
  • Press OK and your phone will be restarted into safe mode.

Perform A Factory Reset

Navigate to

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

Method 5



Before performing this step, backup your important data as factory reset deletes all data and brings back the phone to the state when you first bought it.

There are several ways to create a backup of your phone. Follow the below steps to create a backup first.

  • One of the best options is to make use of Samsung’s very own Kies software that we normally use to update the software of our Galaxy devices.
  • The second way to create a backup of the device is with Google account. Go to Settings > General > Backup & Reset and it will provide two options and those are backup my data and automatic restores. Ensure those options are enabled by ticking the checkbox next to them and it will backup details like Wi-Fi password, app data, Google settings and bookmarks automatically to Google server.
  • Another way to backup your data is using Samsung account. For that go to Application > Settings > User and backup> Account and check if you are signed in to your Samsung account. If the option is set to on, it will sync the contacts, calendar and internet settings to the Samsung account.


The solution was discovered by “Ravi Chandra Timmavajjula” a developer,

I observed that when I was resetting the phone (for the 4th time), and in the second step when it asks for Wi-Fi networks, it was able to scan the networks and connect with a network. Then after following the rest of the steps in configuration(viz. Samsung account login, Google account login, etc.) the same issues start back up.
If this is the case with you, reset your device to factory settings and when it asks for logging into Samsung and google accounts be sure to uncheck restore from server option in both of them (but I think the main problem is mainly with Samsung).
The WiFi option turns on fine now. Then not go to settings>accounts and turn on backup and restore manually for both Google and Samsung one by one. The problem did not rise back up when I followed this process.
