When you need to log into your router settings but you lose access to your control panel, it's one of the most common problems in home networks. Often users forget the data they've changed or buy a device with their hands without knowing its history. In such cases, the first logical step is to try to use the factory credentials that the manufacturer has prescribed for the initial activation of the equipment.
Xiaomi, one of the leaders in the networking market, has implemented several layers of protection and different authorization scenarios depending on the year of release and the specific product line. Understanding which default password is relevant for your model avoids unnecessary hassle and potential resetting that can disrupt the Internet.
In this article, we will take a closer look at all the possible combinations, access recovery methods and security nuances that characterize the Mi WiFi ecosystem, where to look for information on the case, how to distinguish old firmware from new, and what to do if standard methods do not work.
Standard factory data for different generations
The Chinese giant’s networking history has been more than a decade old, and since then, the approach to security has changed dramatically: the very first models to come to market often used a single access system for all devices in a single batch, meaning that the administrator password and Wi-Fi key could be the same and known to a wide range of people, creating certain vulnerabilities.
With the development of the Mi Router line and the introduction of new firmware versions, security policy became stricter. Starting with certain models, such as the Mi Router 3 and later, the system moved to generate unique keys for each device, these data were printed on a personal sticker located at the bottom of the case, the use of universal codes like "admin" is a thing of the past for most modern gadgets.
However, there are exceptions and firmware specific versions, especially in devices designed for the domestic market of China, where the setting requirements may differ from the global versions. In some cases, if the router was not pre-configured by the previous owner, it can expect to set a password on the first connection, without having a hard-defined factory key to log into the web interface.
💡
Always check the production date on the box or case: devices released before 2015 are more likely to use universal passwords, while more recent models require a customized approach.
Where to find a unique access code on the case
The most reliable and quickest way to get the data is to physically inspect the device itself. Xiaomi engineers put an information label on the bottom of the router. This sticker contains all the critical information, including the device model, MAC-address, IP-Entry address and, of course, factory password.
Usually, the label is divided into several sections. You are interested in a field that can be designated as Password, PWD Or Key, often depicted next to it. QR-code scanned by a smartphone, you can automatically switch to setting the device through the Mi Home or Mi WiFi app. This is especially convenient if the sticker is erased and the text is poorly readable.
It is important to note that on some models, such as the Mi Router 4A or Redmi Router AC2100, the Wi-Fi password and the admin panel login password (192.168.31.1) may only match at the time of first activation.
Universal Passwords and Old Models
Despite the trend towards individualization, network engineers and users still have what are called universal combinations, which are especially relevant for very old models or devices that have been fitted with custom firmware that resets security settings to factory standards of the past.
The most common option for early hardware is the admin/admin login/password bundle, a classic of networking hardware found in the early Mi Mini and Mi Nano, and sometimes there is an empty password field where the device only requires login input, or vice versa – login is done without a login, but with a fixed key.
Some specific Chinese firmware versions, which users often install on their own to get advanced functionality, may use combinations like password or 12345678. However, relying on them in 2026-2026 is not worth it, since modern original firmware no longer allows such security holes.
List of rare combinations for older versions
Complete Reset (Hard Reset) procedure
If none of the standard passwords fit and the sticker data doesn’t work (which happens if the router has been reconfigured before), the only way out is to go back to factory status, which completely erases all user settings, including the network name, Internet Password (PPPoE), and Wi-Fi settings.
To perform the reset, most Xiaomi and Redmi routers have a special hole, signed as Reset, inside it is a microscopic button, and to activate it, you need to use a thin object, such as an unbended clip or a toothpick.
The reset process is as follows: turn the router on and wait for it to load (the indicator should be on even light). Press the Reset button and hold it for 5-10 seconds. The indicator will flash orange or yellow, signaling the start of the recovery process. Release the button and wait a few minutes until the device restarts.
☑️ Checklist before router reset
⚠️ Warning: Once reset, the router becomes a blank slate. If your ISP requires authorization (login and password for connecting to the network), you will definitely need this data from the contract. Without it, the Internet will not work even if Wi-Fi appears.
Security setting and password change
Once you successfully log in to the control panel or complete a reset, the first thing you need to do is to take care of security. Factory passwords, even unique ones, are better replaced with your own, since the information from the sticker can theoretically be read by an attacker with physical access to the device.
When you think of a new key, follow the rules of cryptographic resistance. Use a combination of capital and lowercase letters, numbers and special characters. Password length should be at least 12 characters. Avoid obvious sequences, dates of birth or names, as such combinations are easily selected by brute-force.
In the interface of the Xiaomi router (usually at 192.168.31.1 or miwifi.com), the transitions are made intuitively. Find the Settings section -> System Status (Settings) or Wi-Fi Settings (Wi-Fi settings), where you can change the password not only to log in to the admin, but also for the wireless network.
| Model router | Standard IP | Factory login | The factory password. |
|---|---|---|---|
| Mi Router 3 / 3G / 3 Pro | 192.168.31.1 | admin | From the sticker (unique) |
| Mi Router 4 / 4A / 4C | 192.168.31.1 | admin | From the sticker (unique) |
| Redmi Router AC2100 | 192.168.31.1 | admin | From the sticker (unique) |
| Mi Mini/Nano (old) | 192.168.31.1 | admin | admin (or from a sticker) |
| Axia (AX3000/AX6000) | 192.168.31.1 | admin | From the sticker (unique) |
💡
Changing your default password is a basic digital security hygiene that protects your personal correspondence, browsing history, and connected devices (cameras, lamps) from outside interference.
Frequent Connection Errors and Their Solutions
Even with the right password, users often have difficulty logging in. One of the most common mistakes is the confusion between keyboard layout and character register. The system distinguishes between large and small letters, so Password and password are two different keys.
Another problem is connecting to the wrong network. Modern Xiaomi routers often broadcast two networks: 2.4 GHz and 5 GHz. They may have the same names, but different characteristics. If you try to set up a router while in a bad 5 GHz area, the connection can break at the most inopportune moment, creating the illusion of an incorrect password.
Also worth mentioning is the browser cache, which is that if you've tried to log in to the control panel before, the browser might have saved the wrong authorization data, and if you try again, it automatically substitutes it, preventing you from entering the right code, and the solution is simple: use Incognito mode or another browser.
⚠️ Note: Do not use Wi-Fi networks or other computers to enter your router's administrator passwords. Enter only from a trusted device on your home network.
Using the Mi Home application for management
In the age of smartphones, browser-based network management is becoming less popular, giving way to mobile applications. Xiaomi’s ecosystem offers a powerful Mi Home app (or a separate Mi WiFi for some regions) that allows you to control the network remotely.
When you link a router to your Mi Account, the admin panel password is often synchronized with your account password or set automatically, eliminating the need to remember complex combinations. QR-code on the case, and the phone will offer to connect.
Through the app, it is convenient not only to change passwords, but also to track who is connected to your network, limit speeds for individual devices and set up guest mode, which is especially important for owners of smart home devices, where network stability is critical.
