I can find wifi network interface

As you can see from above, I currently only have loopback interface.

So.. what thing I have to do first?
Have to install wireless network driver? Or install another thing?
Can you help me?

Well, maybe. I don't think the wireless NIC driver is installed. Because my uuuntu only shows the loopback interface. — JoonT, Apr 19 '20 at 03:48

If your device has Bluetooth, you can use tethering to connect to the internet via another device using Bluetooth.

1: Connect your device to a device with an internet connection via Bluetooth, such as a smartphone.

2: Click the tray in the top right of the screen and click the WiFi dropdown menu.

3: Connect to your Bluetooth device.

You should now be able to connect to the internet using Bluetooth tethering.

You may have to enable Bluetooth tethering on your internet connected device before following these steps.
