How to set up WPA2 on Xiaomi router: Wi-Fi protection in 5 minutes

Home network protection begins with the correct Wi-Fi encryption setting. Xiaomi routers (Mi Router 4, AX3000, Redmi Router series) often use an outdated WPA/WPA2-PSK protocol or an open network by default - this makes your traffic vulnerable to interception. Setup clean WPA2-AES (without mixed mode) increases security by 3 times, blocking most attacks such as "evil twin" or password selection.

In this article, we will look at the latest MiWiFi firmware for 2026 (including the global and Chinese versions), not only basic configurations through the web interface, but also hidden options for power users, as well as solutions to typical errors like “no settings are saved” or “devices do not connect after changing encryption.” If your Xiaomi router issues an error when choosing WPA2-PSK (AES), here you will find the reason and method of circumventing.

Why WPA2 is better than other security protocols

WPA2 (with AES-CCMP encryption) has been the gold standard for Wi-Fi protection since 2004, despite the advent of WPA3, which is why it is worth using on Xiaomi routers:

• 🔒 Incompatibility with old vulnerabilities: WPA2 plug WEP and WPA-TKIP, Cracked in 5 minutes with aircrack-ng.
• 📱 Support for 99% of devices: Unlike WPA3, It doesn’t work on older smartphones (e.g. Xiaomi Redmi). 4A 2017).
• ⚡ Minimum overhead costs: AES Encrypts data faster than TKIP, What is important for routers with a weak processor (for example, Mi Router) 3G).
• 🛡️ Protection against dictionary attacks: When set up correctly (password) ≥12 characters) selection takes years even on supercomputers.

Important: WPA2-PSK (AES) and WPA2-PSK (TKIP/AES) are not the same thing. The second option supports outdated TKIP for compatibility, but weakens protection. On Xiaomi routers, always choose only AES if all your devices are released after 2012.

Preparing Xiaomi router for setting up WPA2

Before changing security settings, follow these steps to avoid blocking access to your router:

Connect to your router via cable (recommended)| Check the firmware version in Status → Update | Write down your current Wi-Fi password on paper | Turn off the guest network (if any) | Prepare backup internet access (mobile 4G)

-->

Pay special attention to firmware: on Xiaomi routers with MiWiFi version below 2.0.100, there may be no option to select only AES.

1. Update the firmware through Settings → Update (if available).
2. For Chinese versions of routers (CN ROM), install global firmware through the official website.
3. If you can’t update, use the mixed WPA2-PSK (TKIP/AES) mode, but be sure to set a password ≥16 characters long.

⚠️ Note: If your Xiaomi router is locked in connection with your Mi Account (typical for Chinese versions), a reset will lead to a username/password requirement. Check in advance if you remember the data from your account, or untie the router through the Mi Home app.

Step-by-step setting up WPA2 on the Xiaomi router

The instructions are suitable for all modern models: Mi Router 4/4A/4C/5, AX1800/AX3000/AX6000, Redmi Router AC2100. the interface may differ slightly, but the path to settings is the same.

Method 1: Through a Web Interface (recommended)

1. Connect to the router via cable or Wi-Fi. Open your browser and type in the address bar: 192.168.31.1 For some models (for example, the AX6000) 192.168.0.1 or miwifi.com can be used.
2. Enter the login and password (by default — admin/router sticker).
3. Go to Settings → Wi-Fi (or Wireless Settings in English).
4. Find the "Authentication Method" (or Security Mode) field and select: WPA2-PSK If there is no such option, choose WPA2/WPA3-PSK, But then install in the Encryption field: AES
5. In the Wi-Fi Password field, enter a new password at least at least a length of 12 Use symbols: 🔢 Figures: 0-9 🔤 Letters from both registers: A-Z, a-z 🔧 Special symbols:!@#$% (Not the first and last symbol)

Example of a strong password: Xiaomi_AX3000!2026#WPA2 (Don’t use this password – make your own!)

Press Save. The router will restart (up to 2 minutes).

Method 2: Using the Mi Wi-Fi app (mobile)

If the web interface is not available (for example, on Redmi Router with mobile firmware), use the official application:

1. Download Mi Wi-Fi (Android/iOS) and sign in to your Xiaomi account.
2. Select your router from the list of devices.
3. Go to the Wi-Fi settings → Security.
4. Select WPA2-PSK and set a password (similar to the web version).
5. Confirm the changes – the router will restart.

For maximum protection, consider creating a guest network with a separate password for friends' devices or smart home (lamps, cameras) that isolates them from your main network.

1. Go to Settings. → Guest network.
2. Activate the option and set a separate password.
3. In the Isolation section, enable Disable access to the local network.

Password is shorter than 12 characters or contains personal information (date of birth, pet name).

WPS or remote control is enabled.

- Name of the network (SSID) Explains the router model (for example, Mi_Router_4C).
