If you are looking for a way to share the password or key of the Wi-Fi network to which your Samsung Galaxy A21s is connected to be able to share it and quickly configure it on another Android device, be it the Samsung brand or any other, in this tutorial we will show you how find the native way included in the Android operating system from version 10, to generate a QR code with the Wi-Fi password.
The Samsung comes from the factory with the Android operating system version: 10.0 although it may have received new updates over time.
Once the QR code has been generated on your Galaxy A21s, you can read it with the camera of the other device and download it as an image to be able to use it again as many times as you want without having to perform these steps again.
Estimated time: 2 minutes.
1- First step:
First of all we must make sure that we are connected to the Wi-Fi network that we want to share from our Samsung, if so we access the settings of the Galaxy A21s, it is the icon of a gear wheel. If you do not see it on the Samsung Galaxy A21s home screen, swipe up from the bottom of the screen and you will see it.
2- Second step:
Once inside the Galaxy A21s settings, the first option that will appear is “Connections”. Press to access the Wi-Fi network settings.
3- Third step:
Within the connection settings of your Samsung Galaxy A21s the first section that will appear is the Wi-Fi connection. Here we check that it is connected, the icon on the right should appear in blue and the name of the Wi-Fi network on the left, if not, click on the icon on the right with a single touch to activate it and make it appear in blue. Once Wi-Fi is activated on your Samsung Galaxy A21s, click on the left on "Wi-Fi" to access its settings.
4- Fourth step:
Once we are in the Wi-Fi network settings, the available Wi-Fi networks will appear in a list, both those that we have configured and those that we do not. The first Wi-Fi network that appears is the network your Samsung Galaxy A21s is connected to, it should appear as “Current network”. Click on the cogwheel icon that appears to the right of the name of the wireless network to see the details.
5- Fifth step:
We will see the details of the Wi-Fi network saved in your Samsung Galaxy A21s and whose access key we want to share to connect from another device. We go all the way down until we see a QR icon with the text "QR Code" on the left. Press to see the QR code.
6- Sixth step:
The QR code will appear on the Samsung Galaxy A21s screen. Scan the QR code from the other device you want to connect to the Wi-Fi web. If you don't know how to read a QR code, click here to see the instructions.
7- Seventh step:
You can save the QR code as an image to use it directly later or print it and place it in a visible place so that your guests or clients can connect quickly without having to give the network key. You can also share it by pressing the "Share" button on the right.
Remember that you can generate a QR code for each different Wi-Fi network to which you connect from your Samsung Galaxy A21s. If these steps to see the QR code of the Wi-Fi network on your Samsung Galaxy A21s have not been useful, check again that the Samsung Galaxy A21s is connected to the Wi-Fi network and not through the data connection.
If you cannot find the QR code following the indicated steps, you may need to update the operating system of the Samsung Galaxy A21s that comes from the factory with Android version 10.0, see this tutorial: How to update Samsung.
