Home network security is a critical aspect of using any modern hardware, including routers from Xiaomi. Many users do not even realize that standard router settings often use outdated security protocols that are easily bypassed by attackers. Changing the type of encryption is the first and most effective step to prevent personal data leakage and unauthorized access to your Internet channel.
In this article, we will take a closer look at how security settings are configured, explain the difference between popular protocols, and show you where the switches are located in the Mi Router interface or web panel, and the right configuration will take only a few minutes, but will provide long-term protection for your digital space.
Before making changes, you need to understand the risks you may face when using old standards. Modern devices require more robust traffic encryption algorithms. Below we will discuss why you should abandon legacy modes in favor of current security standards.
Choosing the Best Wi-Fi Security Protocol
When setting up a wireless network, the user encounters acronyms that are often confusing.The main options today are WPA2-PSK and the more modern WPA3. WPA2 (Wi-Fi Protected Access 2) has been an industry standard for many years, providing reliable encryption using the AES algorithm. However, even it has known vulnerabilities such as the KRACK attack, although for home use it is still considered quite secure.
The latest WPA3 standard eliminates many of its predecessor’s shortcomings: it protects against brute-force attacks and provides individual encryption for each connected device, even on open networks. If your Xiaomi router supports this mode, switching to it is the most sensible solution to improve the level of protection.
⚠️ Attention: Switching to mode "WPA3 Only" can cause older gadgets (such as smart outlets or smartphones older than 2018) to stop seeing your network.It is recommended to use mixed mode or make sure all devices are compatible.
There is also an outdated WEP protocol that is now considered completely insecure and can be hacked in seconds by even laypersons. Using WEP in today's environment is equivalent to not having a Wi-Fi password. Always make sure that the router's settings remove this option from the list of available ones.
Preparation for setting up the Xiaomi router
Before you start changing system settings, you need to ensure a stable connection to the router's administrative panel. LAN-If you don't have that capability, make sure your device is in a Wi-Fi zone.
You will need to know the login address to the web interface. For most Xiaomi models (Mi Router 3, 4, 4A, 4C, AX1800, AX3600) this is the address 192.168.31.1 or the domain name miwifi.com. You will also need credentials to log in. If you have changed them before, use your administrator password. If the settings have never changed, the password may match the Wi-Fi password or be empty (in old firmware).
☑️ Check before setting up
It is important to note that the interface may vary depending on the firmware version (Chinese or global).In global versions, menus are often translated into English or Russian, whereas Chinese firmware requires the use of an interpreter in the browser or in the application.
Login to the web interface and navigation
The authorization process in the management system of the Xiaomi router is quite simple, but has its own features. Open any modern browser (Chrome, Firefox, Safari) and type in the address bar IP-The router address. The system will ask for the administrator password. Once you've entered it, you'll be taken to the status page, which displays the current speed and number of connected devices.
To change the encryption type, we'll need to go to the Wi-Fi settings section. Depending on the interface version, the path may look different. In the new shell, it's often the Settings tab -> Wi-Fi Settings. In some firmware, you'll need to switch to Advanced mode first to see all available security options.
| Model router | Entrance address | Location of the Wi-Fi menu | Support for WPA3 |
|---|---|---|---|
| Mi Router 4A | 192.168.31.1 | Settings -> Wi-Fi | No. |
| Mi Router AX1800 | 192.168.31.1 | Common Settings -> Wi-Fi | Yeah (in new firmware) |
| Mi Router AX3600 | 192.168.31.1 | Settings -> Wi-Fi Settings | Yes. |
| Mi Router 3G/4 | 192.168.31.1 | Settings -> Wi-Fi | No. |
If you can’t log in, you may need to reset your router to factory settings, but this is an extreme measure as it will remove all your current configurations, including your PPPoE settings from the provider.
What to do if the administrator password is forgotten?
Step-by-step instructions for changing encryption
If you're in the wireless settings section, you'll find the security field, which might be called Encryption, Security, or Auth Type, and that's where you choose the algorithm to protect the data you're transmitting, and the default is often mixed mode, or WPA2-PSK.
For maximum compatibility and security, it is recommended to choose the option WPA2-PSK/WPA3-SAE Mixed (if available) or simply WPA2-PSK with AES encryption. Avoid options with TKIP encryption, as they significantly reduce network speed and are less secure. After selecting the desired item, be sure to click the "Save" or "Apply" button.
⚠️ Warning: After applying the new encryption settings, all devices connected to Wi-Fi will instantly lose connection.
The configuration update process takes a few seconds. The router can restart the wireless module. Make sure you keep the new password in a safe place, as without it, network access will be impossible.
💡
Use a password manager or write down a new complex password on paper immediately after changing your settings, so you don’t forget it before reconnecting all your gadgets.
Configure via the Mi Wi-Fi mobile application
Smartphone owners often find it easier to manage a router through the official Mi Wi-Fi app (available on Google Play and the App Store), a method that is especially relevant if you don’t have a computer at hand. Once you link the router to your Xiaomi account, go to the Tools or Settings section at the bottom menu.
Select "Wi-Fi settings." Here you'll see similar options: network name (SSID), password and encryption type. The application interface is more simplified, so some advanced settings may be hidden. If you don't see a choice between WPA2 and WPA3, then in the current firmware version, this option is hidden or not supported by your device.
The app also allows you to create a guest network with a separate type of encryption, which is a great solution for temporary access of guests, you can set a time limit or speed limit there without compromising the main network.
💡
The mobile app is the fastest way to change your password and encryption type, but for a deep setup of security settings, the web interface provides more options.
Solving Connection Problems After Changing Settings
Once the encryption type is changed, users often find themselves in a situation where the device “sees” the network but does not connect, giving an authentication error, which occurs when the device has an old network profile with incorrect security parameters, the solution is to delete the network from the device’s memory (“Forget the network”) and reconnect.
Another common problem is the incompatibility of older IoT devices (smart light bulbs, vacuum cleaners) with the new WPA3 protocol. If the smart home stops working, go back to the router settings and select WPA2-PSK (AES) mode, the most universal standard that almost all devices released in the last 15 years understand.
It’s also worth checking if you’re not using Double Password or Guest Network, which could have been activated automatically, and make sure you’re entering the password for the main network, not the guest network.
⚠️ Warning: If the router has stopped responding to requests after changing settings or the Internet is lost, reboot the power (turn it off for 10 seconds) This helps to reset the network services that are suspended.
