The situation when a wireless router stops processing traffic correctly or simply refuses to accept the correct password is familiar to many smart home users. Owners of the popular Xiaomi Mi Router 4 model often face the need to return the device to its original state to eliminate software failures or prepare for the sale of a gadget.
Factory reset is a radical but effective measure, and it completely removes all custom configurations, including PPPoE settings, static configurations, and other user interfaces. IP-It is important to understand that once this procedure is done, the router will become a “clean slate” requiring a complete reconfiguration of the provider data. If you are ready for this step, then further information will help you complete the task as safely and quickly as possible, saving nerves and time.
When a complete reset of the router configuration is required
The main reason for the Hard Reset procedure is that you can't log in to the device's web interface because of a lost administrator password. Unlike the Wi-Fi password that you can view on the connected device, access to the control panel is often lost irrevocably if the data was not recorded, in which case flashing the settings remains the only working option to regain control of the equipment.
Also, the reset is relevant when you transfer the router to a new owner or return the device to the store under warranty. MAC-Addresses of associated devices, which ensures the confidentiality of your information.In addition, if the router began to work unstable after updating firmware or installing experimental plugins, returning to stock settings often solves the problem of freezes.
There are a number of less obvious symptoms that indicate the need to clear the configuration memory:
- 📉 A sharp drop in the speed of the Internet connection for no apparent reason on the part of the provider.
- 🔒 Blocking access to the admin panel due to multiple input of incorrect data.
- 🔄 Permanent connection breaks and the need to restart the device.
- 📡 Inability to connect to a Wi-Fi network, although the password is entered correctly.
⚠️ Warning: Before starting the procedure, make sure that you have a contract with an ISP. After the reset, you will need to re-enter your login and password to access the network (PPPoE protocols, L2TP or PPTP).
Preparation for the restoration of factory parameters
Before you press hidden buttons or enter commands, you need to do minimal training, which will avoid a situation where the router is reset and the Internet is not working due to lack of necessary data. First of all, find a contract for the provision of communication services, which indicates the type of connection and authorization data.
If you have the ability to connect to the router via cable, do so. Ethernet wired connection is much more stable than wireless at times of critical configuration changes. Make sure the device is on and the indicators are on with even light, rather than flashing chaoticly, which could indicate a hardware malfunction.
☑️ Pre-reset check
It's also worth checking the firmware version if you still have access to the interface. Sometimes the problem is not solved by a complete reset, but by updating the software to the current version. However, if you're determined to clear the settings, move on to the next step. Remember that all personal settings will be destroyed.
Method 1: Hardware reset with the Reset button
The most reliable method, even if the router is stuck or not responding to requests over the network, is a small hole on the back of the Xiaomi Mi Router 4, signed as Reset, which is designed for disaster recovery.
To do this, you'll need a thin object, like an unbended paperclip or a toothpick. Press the button inside the hole and hold it. The status indicator on the front panel will flash orange. It's a signal that the process is underway. You need to hold the button until the router itself restarts.
💡
If the indicator lit blue immediately after turning on, but the Internet did not appear, then the reset was successful, but the initial setting of the provider was not performed.
It is important to observe time intervals. A short press usually just restarts the device, and a reset requires retention for 5-10 seconds. If you release the button too early, the system may not have time to write down the memory cleanup command.
⚠️ Warning: Do not turn off the router power while the indicator blinks. Interrupting the recording process can damage the bootloader, after which the device will have to be carried to the service center.
Method 2: Software reset via web interface
If you remember the administrator password and have access to the control panel, this will be more convenient and informative. Open the browser and enter 192.168.31.1 or miwifi.com in the address bar. After authorization, go to the settings section.
The interface can be in Chinese or English, depending on the firmware version. You need to find the Status or Common Settings section, where the Reset or Restore Factory Settings button is located, and the system will alert you to the consequences and ask you to confirm the action.
Once confirmed, the router will go into reboot. 2-3 At that time, the Wi-Fi network with your hotspot name will disappear, and a new open network with the name of the species will appear. Xiaomi_xxxx.
The advantage of the software method is that it ensures that all system processes are properly closed before cleaning, while the hardware method is more “rough”, although effective in critical situations.
Method 3: Reset via the Mi Wi-Fi mobile application
Smartphone owners often use Xiaomi’s ecosystem to manage their appliances. Mi Wi-Fi (or Xiaomi Home) allows you to control your router remotely if it’s tied to your account, a method that doesn’t require a computer or paper clip to be found.
Go to the app and select your router from the list of devices. In the management menu, find the Settings section (usually the gear icon or three dots in the corner). Scroll down to Reset Settings or Reset Router. The system will require confirmation of operation.
Once you have completed the command, the router will restart, and this method only works if the router is online and linked to your account, and if you have forgotten your password and can't log in, it won't work.
| Parameter | Hardware discharge | Web interface | Mobile app |
|---|---|---|---|
| Network access | Not required | Required. | Required (Wi-Fi/4G) |
| I need the admin password. | No. | Yes. | Yeah (account login) |
| Risk of error | Medium (human factor) | Low. | Low. |
| Speed of implementation | 1-2 minutes | 2-3 minutes | 1-2 minutes |
Primary adjustment after reset
Once the procedure is completed successfully, the router will return to the out-of-the-box state, connect to an open Wi-Fi network with the name on the sticker at the bottom of the case, or use it. LAN-The first time you connect, the Quick Setup wizard page will automatically open.
The system will suggest you choose the type of connection. You'll need data from your ISP contract. You'll select a protocol (most commonly PPPoE for home networks) and enter your login and password. Without this step, the Internet will not work, even if the indicators are green.
What to do if the setup wizard does not start?
Next comes the step of setting up wireless network security: Create a complex Wi-Fi password so that neighbors don't use your traffic, and WPA2-PSK or WPA3 encryption is recommended if devices support this standard.
💡
Once reset, the router creates a new access point, and the older devices will not be able to connect automatically, you need to “forget” the network on the phone/laptop and enter the new password again.
Frequent problems and ways to solve them
Sometimes the recovery process goes wrong, for example, a router may reset but not create a Wi-Fi network, in which case try to wait 5-10 minutes after turning on, the device may do internal defragmentation or file system checks.
Another common problem is not being able to access 192.168.31.1. Make sure that your computer or phone has automatic receipt. IP-Static addresses. IP, Previous address may conflict with new router address range.
- 🔌 Check the power cable: Use the original unit as power shortages can cause cyclical reboots.
- 🌐 Try another browser: Sometimes extensions block the scripts of the settings page.
- 🔄 Use cable: if Wi-Fi is not caught, it is better to conduct the setting over the wire.
If neither method works and the router continues to behave inadequately, it may be hardware or flash memory damage that may require UART flashing or service access.
