Changing the password on a Xiaomi router is the basic procedure every router owner needs immediately after buying it.The factory access data listed on the sticker at the bottom of the case is often generic or too simple, making your home network vulnerable to unauthorized intrusion.Neglecting this security step can lead to identity theft or the use of your channel for illegal activities by third parties.
Changing your Wi-Fi access key or administrator password doesn’t require a deep knowledge of networking. Xiaomi’s device management interface, whether it’s a classic web bar or a Mi Home mobile app, is designed to be as intuitive as possible. In this article, we’ll take a look at both methods in detail so you can choose the most convenient configuration option.
Before you start changing your settings, make sure your device (smartphone or laptop) is connected to the router wirelessly or via a wireless network. LAN-If you change your password remotely from home, make sure that the remote control function is already activated in the device settings. Otherwise, you will have to be within range of the signal.
Preparation for network security setting
The first step is to collect the necessary information and check the current connection settings. IP-The gateway address, which by default on Xiaomi routers is most often 192.168.31.1 or miwifi.com. It is also worth preparing a new password that will meet modern cryptography standards: the length of at least 12 characters, the use of numbers and letters of different registers.
If you plan to use your computer to set up, it's best to connect it to your router with an Ethernet cable, which ensures that when you change your password, the connection doesn't break and you don't lose access to the control panel. Wireless connectivity is also acceptable, but when you change your Wi-Fi key, the device will need to reconnect with the new data.
⚠️ Warning: After changing your Wi-Fi password, all connected devices will automatically shut down.You will have to re-enter a new access key on every smartphone, tablet and smart gadget in your home.
It is important to distinguish between two types of passwords: the password to log in to the control system (admin) and the password to connect to the wireless network. The first protects the settings of the router from changes by outsiders, the second restricts access to the Internet. It is recommended that these passwords are different from each other to improve security.
Change password through the router web interface
The classic way of setting up is through any modern browser. Open the address bar and type 192.168.31.1 or miwifi.com. The system will request authorization: enter the current administrator password. If you change it for the first time, it can be the password you came up with when you first activated, or the standard one if the router was reset.
Once you're successfully logged in, you'll be taken to the main status page, which displays the list of connected customers and the current traffic speed. To change the Wi-Fi password, you'll need to find a section, usually called Wi-Fi Settings or Wi-Fi Settings. Depending on the firmware version (MIWiFi OS), the interface may differ slightly visually, but the logic remains the same.
In the window that opens, look for the Password or Encryption field. Delete old characters and enter a new combination. Make sure you choose the type of WPA2-PSK or WPA3 encryption if your devices support this standard. Old protocols like WEP are strongly discouraged because of their low resistance to hacking.
☑️ Pre-conservation checks
Once you enter the data, click Apply or Save. The router will restart the wireless module and the connection on your device will be interrupted. Find your network in the list of available and connect using a new key. If you have access to the Internet, the procedure was successful.
Change your password through the Mi Home app
Smartphone owners often find it easier to manage their network through the Mi Home mobile app, which allows you to change your settings remotely if the router is linked to a Xiaomi account. Open the app, find your router in the list of devices, and click on it to go to the control menu.
In the application interface, select Settings (cog icon) or Wi-Fi. This displays the network name (SSID) and the current password. Click on the password field to edit it. The application may suggest generating a complex password automatically, which is a good practice to increase protection.
A feature of mobile management is the ability to create a guest network, a separate Wi-Fi with its own password that does not allow access to the main devices on your local network, such as printers or other devices. NAS-Guests can be given a password from the guest network, securing their basic data.
💡
Use the Guest Network function for temporary access of visitors, so as not to disclose the main password from the home network and not to connect other people's devices to local resources.
When the settings in the app are changed, the router will automatically apply them, and a notification may appear on the smartphone screen that the network settings have changed and the device will be reconnected. If the connection does not happen automatically, turn off the Wi-Fi on the phone and turn it on again.
Setting up the system administrator password
In addition to protecting the wireless access point, it is critical to protect the router control panel itself. If an attacker gains access to the administrator settings, they can redirect the DNS, change the firewall rules, or even block you from accessing your own hardware. To change this password in the web interface, go to Settings → System → Administrator password.
The system will ask you to enter your current password and double-validate your new one. Come up with a unique combination that you don't use on other sites or services. It's a good practice to use a password manager to store these complex keys, because you can't remember them all.
| Parameter | Recommended value | Safety impact |
|---|---|---|
| Password length | 12+ characters | High: Increases selection time |
| Type of encryption | WPA2/WPA3 | Critical: Protects traffic |
| Remote access | Off. | High: Closes access from outside |
| Network name (SSID) | No personal data. | Medium: Hiding the owner |
Some Xiaomi routers allow you to disable the ability to change your settings over Wi-Fi, requiring a physical connection of the cable to log into the admin. This is the maximum level of protection available to the home user, as it eliminates the possibility of remote hacking through vulnerabilities of the wireless protocol.
What to do if the router password is forgotten
When a Wi-Fi password or administrator panel is lost, it is common. If you can't log in, the only reliable way to restore access is to reset to factory settings. On the case of the Xiaomi router, usually on the back, there is a small hole that says Reset.
To do the reset, turn the router on the network. Take a paper clip or toothpick, press a button inside the hole and hold it for 5-10 seconds. Indicators on the case should blink or go out, which signals the start of the recovery process.
⚠️ Warning: Full Hard Reset will remove all your personalized settings, including provider settings, network names and macros.
Once reset, you can log in using the data on the sticker under the device's body, usually the absence of a password on the first sign-in or the standard combination. Immediately after login, be sure to set new passwords to keep the network open.
