Loss of access to wireless networks is a familiar situation for many users, especially when new gadgets are introduced or guests arrive. The owner of the Xiaomi Mi Router 4C router may be faced with the need to remember a previously installed security key if it is forgotten or lost. Fortunately, the architecture of these devices allows you to restore access with several proven methods that do not require deep knowledge in network technologies.
Password recovery is possible both through software through the web interface and by physically affecting the device body. It is important to understand that the standard password is often indicated on the sticker, but if you have changed it before, a deeper diagnosis will be required. In this article, we will discuss all the current ways to access your WiFi network without losing important data, if possible.
Before you start taking drastic measures, it’s worth checking the most obvious credential storage locations. Many users forget that they may have written the key in a phone or on a computer that is already connected to the network. Xiaomi 4C is a popular model, and there are several specific recovery nuances for it, which we will discuss in detail below.
Search for password on the device body and in documentation
The easiest and fastest way to get access data is to inspect physical labeling. On the bottom of the Xiaomi Mi Router 4C case, there's a sticker on the back of the router. This is where the manufacturer puts the factory settings that are relevant to the device out of the box. If you've never changed the security settings manually, the data here will work.
Note the field, designated as WiFi Password or simply Key. In some firmware revisions, the password may match the password. MAC-It is also worth checking the original box or instructions if they are preserved, although the sticker on the case is a more reliable source.
If you've done a setup before and changed the standard values, the sticker information will be useless, and then the factory key won't work, because the router uses updated data stored in its nonvolatile memory, and then you'll have to use other methods.
⚠️ Warning: The sticker may fade over time or be damaged by moisture.If the text is not readable, do not try to wipe it off with aggressive chemistry, use software recovery methods better.
For convenience of perception of factory data, here is an example of what you can see on the label:
| Parameter | Description of meaning | Where to find |
|---|---|---|
| SSID | Network name (e.g, Xiaomi_4C_XXXX) | Sticker on the bottom |
| Password | The factory access key | Sticker on the bottom |
| IP Address | Entrance address (usually 192.168.31.1) | Sticker/Instructions |
| MAC Address | Unique equipment identifier | Sticker on the bottom |
Viewing the saved password on the connected computer
If your WiFi network previously had a laptop or desktop PC running Windows, the operating system could have saved the access key, so you can learn the password without directly logging into the router's settings, which works if the computer has ever successfully connected to the Xiaomi 4C network.
To get the information, go to the Network Control Panel. Right-click on the connection icon in the tray and select "Open Network and Internet settings." Next, look for the link "Network and Sharing Center" or immediately go to configure the adapter settings.
In the network connection window, find your wireless adapter, click on it and select Status. In the dialog box that opens, click on Wireless Network Properties, go to Security tab, and tick the box against Display Typed Signs.
💡
If you have a Mac OS, open Keychain Access, find your network name in the list, double-click on it and tick the “Show Password” box, confirming the action with the login code.
An alternative way for advanced users to use the command line is to quickly output data without wandering through the menu.
netsh wlan show profile name="Name your network" key=clearIn output commands, find the “Key Content” line, where the desired character will be indicated.
Log in to the web interface of the Xiaomi 4C router
The most universal way to manage settings is by entering through the browser, and for this, the device must be connected to the router via cable or WiFi (if you know the password or the network is open). Open any browser and enter in the address bar IP-address: 192.168.31.1 or miwifi.com domain.
Once the login page is loaded, the system will ask for an administrator password. Often users confuse it with a WiFi password. By default, when you first set up the Xiaomi Mi Router 4C, you will want to make these passwords the same. If you haven't changed the administrator password separately, try entering the wireless key.
If you are successful, go to Settings -> Status or WiFi settings, and here in the Password field, you will see the current security symbols for your network, and you can copy them or change them to new ones.
☑️ Checking access to the admin panel
If the administrator password is lost and you cannot log in, you will need a reset procedure, which will be discussed below. However, before you do a hard reset, try to remember whether you used simple combinations or date of birth.
Use of the Mi WiFi mobile application
Smartphone owners can control the Xiaomi 4C router through the official Mi WiFi app (or Xiaomi Home depending on the region).This is a convenient way to (check) settings if the phone was previously tied to the router. The application allows you to see the password from the guest network or the main one if the phone already has administrator rights.
Run the app and make sure your smartphone is connected to the router's network. In the main menu, select your device. Go to Settings (cog icon) -> WiFi settings. This will show the current password, which you can copy to the clipboard or change.
The advantage of the mobile method is that the application can automatically sync passwords to the cloud account Mi Account. If you sign in from a new device, the settings can be adjusted automatically, allowing you to learn the password without entering complex combinations manually.
It is worth noting that the functionality of the application may vary depending on the firmware version (Chinese or global), in some cases, the router is required to be linked to Mi Account for full access, which increases security, but makes it difficult for guests to log in.
Resetting the settings of the Xiaomi 4C router to the factory
If none of the previous methods worked, the last, but guaranteed option is a full reset (Hard Reset), which will return the Xiaomi Mi Router 4C router to the “out of the box” state, all your settings, including the network name, WiFi password and administrator password, will be replaced with factory ones.
To perform the reset, find a hole on the back that says Reset. Take a paper clip or a thin object, press a button inside the hole and hold it for 5-10 seconds. The status indicator on the case will flash orange, signaling the beginning of the recovery process.
After the router restarts and the blue indicator lights up, you can connect to the network using data from the sticker at the bottom of the device.
⚠️ Warning: Reset will remove all personalizations, including parental control settings, static IP Make sure you have a contract with the provider to reconfigure the Internet.
The process takes no more than 2-3 minutes. Do not turn off the router power while the indicator blinks, so as not to damage the software.
Frequent errors and problems in recovery
Users often face a situation when the browser does not open the page. 192.168.31.1. This may be due to the fact that the computer’s network card is configured to be static. IP-address that conflicts with the router's subnet. TCP/IP and set the receipt of the address automatically.
Another common problem is that antivirus or firewall block access to the local management page, and it is also worth trying another browser or incognito mode, eliminating the influence of cache and extensions. DNS-cache by ipconfig /flushdns command-line.
If the Xiaomi 4C router stopped distributing WiFi after trying to change the password, there may have been a firmware failure, in which case it is recommended to update firmware through the web interface by downloading the current version from the official website.
What to do if the Reset button doesn’t work?
Remember that changing passwords to complex combinations often without writing them leads to similar situations: use password managers or write data to a secure location immediately after setting up.
WiFi network security recommendations
Once you've successfully restored access, you should think about the security of your network. The standard password on the sticker is often too simple or public for this model, and you should install a unique encryption key, which consists of different register letters, numbers and special characters.
Choose a modern WPA2-PSK or WPA3 security protocol if your devices support it. Avoid using outdated WEP encryption, which is hacked in minutes even by a beginner. Also disable WPS, as it is a vulnerability of many routers.
Check the list of connected customers in the web interface regularly. If you notice an unknown device, immediately change your password and block the guest. Xiaomi Mi Router 4C allows you to create a guest network with limited access to local resources, which is convenient for visitors.
💡
Network security begins with a strong administrator password other than a WiFi password and a regular update to the router’s firmware.
Compliance with these simple rules will protect your personal data from theft and prevent unauthorized use of your Internet channel.
