If you’ve ever had to connect to someone else’s Wi-Fi network on your Xiaomi or Redmi, you’ve probably come across WPSLite, a tool often marketed as a “magic wand” for password circumvention, but it’s actually based on protocol vulnerabilities. WPS (In this article, we will take a closer look at what WPSLite is, how it interacts with Xiaomi devices, and why using it can be dangerous – both for your smartphone and the owner of the network.

It's important to understand that WPSLite is not official software from Xiaomi, it's a third-party application that uses outdated security protocols in routers, and many users mistakenly believe that it "hacks" networks, but in fact it just slices through the network. PIN-code WPS, The default router is often installed by router manufacturers (e.g. 12345670 or 00000000).In 2026, most modern routers have already closed this vulnerability, but some budget models (including those from older versions of Xiaomi Mi Router) may remain vulnerable.

Before we go into the technical details, the big question is: Is it legal to use WPSLite? In most countries, no, if you connect without the owner's permission. Even if your goal is to just check the security of your own router, it's better to use legal tools like Wireshark or the built-in diagnostics features in Mi Wi-Fi.

What is it? WPS And why is he vulnerable?

Protocol WPS (Wi-Fi Protected Setup was designed to make it easier for devices to connect to Wi-Fi, instead of entering a complex password, the user could use the Wi-Fi device:

• 🔢 PIN-code (8 digits, often listed on the router sticker)
• 🖱️ Button WPS (physical button on the router body)
• 📱 NFC (compatible)

The problem was architecture. PIN-code: it is divided into two parts (4 + 4 numbers, and the router checks them separately, allowing attackers to sort through the combinations in the 10 000 times faster than full 8-This is the vulnerability that WPSLite exploits, which is not cracking the Wi-Fi password, but picking up the Wi-Fi password. PIN WPS, After that, they access the network.

Modern routers (including Xiaomi Mi Router) 4A Gigabit, Redmi Router AX5 and newer) by default, disable WPS limit the number of attempts to enter PIN. However, on older models (such as Mi Wi-Fi Mini or Mi Router 3), this feature can be active.

⚠️ Note: If your Xiaomi router is released before 2018, check your settings WPS Disable this feature if it is not in use, this will reduce the risk of unauthorized access.

How does WPSLite work with Xiaomi devices?

1. Does the router support the protocol? WPS.
2. Is the function active? PIN-authentication.
3. Are there any standard PIN-codes (e.g. 12345670 or combinations from the manufacturer).

On Xiaomi devices (especially with the MIUI 12+) There may be problems:

• 🚫 Locking the installation: MIUI Default prohibits installation APK To get around this, you need to turn on Settings. → Annexes → Special rights → Installation of unknown applications.
• 🔋 Increased battery consumption: Continuous network scanning drains battery 15-20% faster.
• 🛡️ Protection: Antiviruses (e.g. Mi Security) can remove WPSLite as potentially dangerous software.

If an application finds a vulnerable router, it connects to the network and can:

• 📡 Show Wi-Fi password (if the router uses it) WPA/WPA2).
• 🔑 Save. PIN-reconnection.
• ⚙️ In some cases, access the router control panel (if you use a standard login / password like admin/admin).
