In this article, we're going to look at not only the basic connectivity algorithm, but also the hidden nuances that the manufacturer doesn't always put out. QR-The codes don't recognize how to create your own code for the guest network or what to do if you see a "Disconnected" error after scanning, and you'll learn how this function works in different versions. MIUI (10 to 14) and what alternative Wi-Fi connectivity options are available for the Redmi Note 7.

Why is the connection through QR-code is more convenient than the usual method

Step-by-step: how to connect to Wi-Fi through QR-code

Now, let's get to the process. Follow the instructions carefully, because some steps depend on the version of MIUI:

  1. Open your Wi-Fi settings: Swipe down from the top edge of the screen to open the notification bar, and click on the Wi-Fi icon (or go to Settings β†’ Wi-Fi).
  2. Click on the icon. QR-Code: In the upper right corner of the screen with the list of networks you will see the icon QR (on MIUI 12+ It can be hidden under three menu points).
  3. Allow access to the camera: When you first start, the system will request permission – confirm it.
  4. Put the camera on QR-Code: Place the code in the center of the screen. If the code is on another device, make sure that its screen is not turned off or locked.
  5. Confirm the connection: after a successful scan, the network name and the Connect button will appear – click it.

If it went well, you'll see a tick next to the network name and a connection icon in the status bar, and if it didn't, go to the Problem Solving section.

How to create your own QR-Wi-Fi code on Redmi Note 7

You can't just scan other people. QR-And you can also generate your own codes, for example, to connect your guests to your network quickly:
