Connecting to Wi-Fi over QR-code on Xiaomi smartphones: full instructions

Connecting to Wi-Fi via QR-The code on Xiaomi smartphones is a quick and convenient way to avoid manually entering complex passwords.The technology works on most of the brand's modern devices, starting with the introduction of a new code code. MIUI 12 and more recent, but many users still don't know it exists or experience errors when trying to use it, and in this article we'll look at not only the standard connection algorithm, but also the nuances that the manufacturer does not mention: From checking your model’s compatibility to solving typical problems like "QR-code not recognized" or "connection interrupted".

The feature of the method is that it uses the Wi-Fi Easy Connect protocol (formerly known as Wi-Fi Aware), which encrypts network data in graphical code, not only saves time, but also reduces the risk of errors when entering long passwords with characters from different registers. However, it is important to consider several key points for successful connection, from the firmware version to the camera settings.

What Xiaomi models support QR-code connection

The function is available on all devices under control MIUI First, Xiaomi is gradually abandoning support for older models (such as the Redmi Note 5 or Mi 8 Lite), which can not physically upgrade to current versions of firmware.

Security: Risks of connecting QR-code

Although it's convenient, it's not without vulnerabilities.

• 🕵️ Fake. QR-codes: Attackers can place codes in public places (such as cafes) that are redirected to phishing pages.
• 🔓 Data Leakage: If the code is generated through an unreliable service, the Wi-Fi password may be passed to third parties.
• 📡 MITM-Attacks: when connecting to public networks through QR interception.

How to minimize the risks:

• 🛡️ Use only. QR-codes generated by trusted sources (routers, official applications).
• 🔒 After connecting to the public network, turn on VPN (For example, ProtonVPN or Windscribe).
• 🚫 Disable Autoconnection to Open Networks in Settings → Wi-Fi → Additionally.
