Modern Xiaomi routers are complex computing devices that, like smartphones or computers, accumulate temporary data as they work. Over time, overflowing the system buffer can lead to slow data transfer speeds, connection breaks or a complete freeze of the web interface. Users often face a situation where the Internet is unstable, and the first question is whether it is possible to clean the cache in the Xiaomi router to fix the situation without buying new equipment.
Unlike mobile operating systems, where cleaning the cache of applications is a routine procedure, network hardware does this differently. There is no "clean everything" button, because the architecture of the router's operating system involves automatic memory management. However, there are proven methods to force free resources and reset accumulated errors, which we will discuss in detail in this article.
Understanding exactly how temporary file storage works will help you make the right decisions when diagnosing network problems. Xiaomi router cache is a RAM area (RAM) not a flash memory, so it is completely cleared with each power outage. However, there are nuances of software cleaning that require careful attention and adherence to certain algorithms of actions to achieve maximum effect.
What is a router cache and why it should be cleaned
In the context of network devices, cache is most often understood as temporary entries in a table. ARP, DNS-Cache and buffer system logs. When you connect a lot of gadgets, the router has to keep track of them all the time. IP-If errors or broken records accumulate in this database, the device begins to waste resources on processing incorrect requests, which directly affects network performance.
This is especially true for models that are running in high load mode, such as when downloading large amounts of data or using torrent clients directly on the router. IP-Regular prevention helps maintain connection stability throughout the life of the equipment.
It's worth noting that some users confuse cache with logs or temporary firmware files, and it's important to distinguish between these concepts because the way they work with them is different. Cleaning system logs doesn't always increase speed, but it helps to make room for new events to be recorded, which is critical when debugging network problems.
- 📉 Reduced network response speed when multiple devices are running simultaneously.
- 🔌 Frequent connection breaks or the need to constantly restart the router.
- 🌐 Inability to open the web interface settings due to overflow of the request buffer.
- ⚠️ Mistakes in work DNS, When the sites are not opened, but messengers are functioning.
⚠️ Attention: There is no single command to completely clean the entire memory of a router, as on a smartphone. The optimization process is a set of actions to reset individual network services and routing tables.
Method of software reboot through the web interface
The safest and most effective way to clean RAM is to programmatically reboot through the control panel. Unlike simply pulling the cord out of the socket, this method allows the system to correctly complete all background processes and maintain the integrity of system files. To access the settings, you need to know IP-The default address for Xiaomi is often 192.168.31.1 or 192.168.1.1.
Once you log in, you'll need to find the partition that's responsible for the state of the system, and in Chinese firmware it can be called "Status" or "System," in global ones it can be called "Settings." That's where power management and diagnostics are, and using the standard interface tools ensures that you don't damage the network configuration.
It's important to understand the difference between a reboot and a reset. Reboot clears RAM, but it keeps all your Wi-Fi settings, passwords, and filtering rules. Resets return the device to factory status by removing user data. Be careful when choosing options on the menu so you don't accidentally lose network configuration.
☑️ Safe Reboot Algorithm
Cleanup DNS-cache and network tables
One of the most common reasons why the Internet slows down or does not open individual sites is overflow of cache. DNS. Router remembers. IP-If the record is outdated or the site has changed the server, the device may continue to try to connect to the old address. To solve this problem, Xiaomi routers have the ability to reset DNS-client.
In some models with an open operating system or support for plugins, you can forcibly clean tables. ARP and DHCP. This is especially useful if you frequently change devices on the network or use static devices. IP-Cleaning up these tables forces the router to re-question all the connected gadgets and update their status information.
For advanced users who have access to the command line via Telnet or SSH (which requires pre-activation in hidden menus), a deeper cleanup is available. However, for most users, it is enough to reset network settings through the GUI, which is equivalent to clearing the connection cache.
| Cache type | Impact on work | Cleaning method | Risks. |
|---|---|---|---|
| DNS | Speed of opening websites | Changing DNS Servers | Absent. |
| ARP table | Communication within the local network | Router reboot | Temporary disconnection |
| System Logs | Taking a place in memory | Cleaning up the logs on the menu | Losing a history of error |
| Boot buffer | Speed of downloading files | Stopping torrents | Interrupting of loadings |
Use of the Mi Wi-Fi mobile application
Smartphone owners can control their Xiaomi router through the official Mi Wi-Fi app. It is a handy tool that allows you to perform basic diagnostics and cleanup of the system without having to connect to a computer. The functionality of the application often duplicates the web interface, but is presented in a more understandable, mobile format.
The Settings or Tools section often provides a network status check feature, and the app can automatically offer optimization that includes closing background processes and clearing temporary data, especially for users who don’t want to understand complex network terms.
It is worth considering that the functionality of the application may differ depending on the region in which the router was released and the firmware version. Chinese versions of the application may contain more tools for fine-tuning, while global versions are focused on ease of use.

Radical measures: reset to factory settings
If the software methods fail and the router continues to run unstable, the only reliable way to clear the cache and return the system to its original state is a full reset (Hard Reset).This procedure removes all user settings, including Wi-Fi passwords, provider settings and port forwarding rules.
To perform the reset, the device has a special Reset button, which is usually recessed into the case to avoid accidental pressing. You will need a thin object, such as a paper clip or a toothpick, and the procedure must be carried out strictly according to the instructions so as not to damage the device's software.
Once reset, you will have to reset your Internet connection. Make sure you have the data from your provider (login, password, connection type) as the router will not be able to automatically restore it out of nowhere. This is an extreme measure to resort to when other methods have exhausted themselves.
⚠️ Warning: Before performing a full reset, be sure to record or photograph the current network settings so as not to lose important configuration data.
Prevention and optimization of the router
To avoid the need for frequent cache cleaning and reboots, it is recommended to follow certain rules for the operation of network equipment. Xiaomi routers, like any electronics, are sensitive to overheating and voltage surges, which can accelerate memory degradation and the appearance of errors in work.
Regular firmware updates are an important aspect of maintaining a device’s health, and manufacturers are releasing patches that not only close security vulnerabilities, but also optimize memory management by fixing resource leaks that may have been in previous software versions.
💡
Install your router in a well-ventilated location, away from heat sources and other electronic appliances, to prevent overheating and stabilize components.
It’s also worth limiting the number of connected devices if you notice that the router is not coping with the load. Older models may have restrictions on the number of simultaneous connections, and exceeding this limit leads to overflow of tables and performance drops.
💡
Regular reboot once a week is the best prevention of accumulation of errors in the router cache, allowing you to maintain a stable Internet speed without complex manipulations.
