Solution:
Via QR code:
One of the fastest and almost instantaneous ways to get to share the wireless connection from a Xiaomi, REDMI or POCO mobile will be through a QR code that can be scanned from the device that wants to use our Wi-Fi or data. Therefore, in order for us to achieve it, this is what we must do:
Within the MIUI Wi-Fi zone settings you can find an option called 'Share QR code'.
By clicking on the button, a QR code will appear, despite the redundancy, which will have to be scanned by whoever wants to connect to your data network. Simpler impossible.
Be careful, do it with someone you are completely sure of, since he is not going to ask you for a password or access credentials.
Via Bluetooth:
In addition to being able to do it by QR code or password, there is a third option to share data on Xiaomi. Of course, this system is somewhat slower than the previous ones, since the synchronization protocol between the phones is different. To do this, you simply have to activate the Bluetooth of all the devices that are going to share the Internet and, then, in the Access Point or Portable Wi-Fi Hotspot menu, there is the Bluetooth Connection option. You just have to activate it and go.
At this point, what the smartphone will do is locate devices within Bluetooth range and ask you to confirm. The destination mobile will show you the option to connect to the Internet through this system. Just accept and go.
Via USB:
In the event that you want to share the data through a USB connection, you will only have to connect your Xiaomi mobile to the USB port of the device to which you want to share your network. After this, you must follow a specific procedure from the native configuration of your Chinese device:
Access the Settings.
Tap on the Portable Hotspot option.
Once inside, you must activate the USB tethering option.
From now on you will be shown a series of tips on the screen that you must strictly follow to configure this connection and turn your smartphone into a small travel router.
