How to speed up the Internet on Xiaomi: from simple settings to hidden settings

A modern smartphone cannot be imagined without a stable connection to the network, and when Xiaomi begins to slowly load pages or interrupt video streams, it causes irritation. Users often face a situation when the declared rate of the tariff does not correspond to the real performance on the screen of the gadget. Owners of devices of the line of Redmi and Poco are especially sensitive to system optimization, since the MIUI shell or the new HyperOS have their own characteristics of working with network protocols.

There are many reasons that affect connection quality, ranging from banal problems with carrier coverage to software conflicts inside the Android operating system. It is not always the fault of the provider or the cell tower - often the problem lies in incorrect DNS settings, outdated certificates or crowded cache of network services. In this article, we will discuss complex methods that will help you to squeeze the most out of the available communication channel.

Before we get to the tricky part, we need to rule out obvious factors, such as overheating of the communication module or physical damage to the antenna after a fall. Internet speed depends on the quality of the signal, so in areas of uncertain reception, software tricks may not give the desired effect. However, in 90% of cases, competent network settings can significantly improve the response of the system and the speed of downloading content.

Diagnostics of current speed and connection quality

The first step is to objectively assess the current state of the network, as the subjective feeling of “slow” can differ from the real numbers. To make accurate measurements, it is recommended to use specialized applications such as Speedtest by Ookla or the built-in tester in the menu of engineering settings. It is important to conduct testing at different times of the day to eliminate the impact of load on the operator’s network during peak hours.

Not only do you look at downloads and uploads, but you also look at the Ping parameter, which shows server response delay. High ping is often the cause of lags in online games and heavy pages loading, even if the file download speed is formally high. If the ping jumps or exceeds 100 ms on a good signal, the problem may be routing traffic or congestion of the channel.

For Wi-Fi-connected users, it is critical to check how fast the router is running, as the 2.4GHz band is often littered with neighboring access points. Switching to 5GHz allows you to significantly increase channel bandwidth and reduce interference if your router and smartphone support this standard.

• 📶 Check the signal level in the state settings SIM-card or Wi-Fi adapter.
• ⏱️ Measure ping to different servers to eliminate problems with a specific hosting.
• 📡 Make sure the smartphone is not in energy saving mode that limits background activity.
• 🔄 Reboot router and modem to reset temporary network errors.

⚠️ Note: If the speed of the Internet dropped sharply after updating the firmware, the problem may be incompatibility of the new modem drivers with your carrier.

Basic optimization of Wi-Fi and mobile network settings

To begin troubleshooting, check for basic configurations that often change automatically or get lost after a system update. Xiaomi owners need to go to the Settings → Wi-Fi → Wi-Fi settings and make sure that the Wi-Fi Assistant option is enabled if the signal is unstable. This feature allows the smartphone to automatically switch to mobile Internet when the wireless network becomes too slow.

For a mobile network, it is important to choose the right type of preferred network, as forced use is a must. 4G/LTE It can be useful in areas where the signal is 3G It's a bit harder, but it's a little slower. In the network selection menu, sometimes you should try to manually select the operator instead of the automatic mode, so that the phone doesn't try to jump between towers of different standards. APN (access points, especially if you have changed the tariff operator or use a corporate SIM-map.

One of the common reasons for slow work is the accumulation of errors in network settings, which are solved by simply resetting the network to factory settings. This procedure will not delete your personal files or contacts, but will return all network settings, including Wi-Fi passwords and Bluetooth pairings, to their original state. Once reset, the phone will create new, clean connection configurations, which often solves the problem of “sticking” at low speed.

Remember that some MIUI shell features, such as Flight Mode or Data Savings, can aggressively restrict background data transfers, and disabling these features for mission-critical applications can improve performance but increase battery consumption.

Shift. DNS-servers to speed up response

One of the most effective ways to speed up the opening of sites and applications is to replace the standard ones. DNS-Providers often use their own servers to make faster and more reliable alternatives. DNS, These can be overloaded or slow to process requests, creating a delay before the page loads. Using public servers from Google or Cloudflare reduces domain resolution time and speeds up response.

In modern versions of Android and the shell HyperOS change DNS You can do it without root rights through the “Private” function. DNS» (Private DNS). To do this, go to the Settings. → Connection and sharing → Private DNS Select the "Host Name of the Provider" mode DNS». In the field that appears, you need to enter the address of one of the fast servers, for example, dns.google or 1dot1dot1dot1.cloudflare-dns.com.

After applying the new settings, it is recommended to restart the smartphone so that the DNS cache is completely cleared and the new settings take effect. If you notice that some local resources or operator sites have stopped opening, return the settings to Auto or Disconnected mode.

💡

Use the DNS Changer app to quickly switch between DNS profiles without manually entering addresses each time.

Use of engineering menus and hidden codes

For more advanced users who want to gain full control of the network module, the Xiaomi engineering menu is available, hidden from the average user. It can be accessed by typing code ##4636## in the phone book, then a testing menu will open, where you can see detailed signal statistics and control the modes of operation of the radio module. Here information about the signal level in dBm is available, which is more accurate than the standard “rods” on the screen.

In the Phone Information menu, you can force the network mode to be switched, for example, by installing only LTE Only if you are in an area where the phone is constantly trying to catch 3G or 2G. Be careful: setting the LTE Only mode can cause incoming calls to stop coming if your carrier does not support VoLTE. To return to normal mode, select NR/LTE/GSM/WCDMA auto.

Code for entry: ##4636##


Phone Information -> Set Preferred Network Type

Another useful feature is resetting network usage statistics, which helps the system recalibrate switching algorithms between towers. In the same test menu, you can find the Run Ping Test button, which allows you to check the quality of the connection to the operator's gateway in real time, bypassing third-party applications.

⚠️ Warning: Changing the settings in the engineering menu can lead to unstable communication or complete disappearance of the network!

Cleaning the system and removing network debris

The accumulation of temporary files and cache of system services can indirectly affect the speed of the Internet connection, creating (bottlenecks) when processing network requests. First of all, you should clear the cache of applications that actively use the network, such as browsers, messengers and app stores. To do this, go to Settings → Applications → All applications, select the desired application and click “Clear Cache”.

Also worth paying attention to background processes that can consume CPU traffic and resources, slowing down active tasks. In the Battery and Performance menu, you can limit background activity for unused programs, which will free up the channel for important tasks.

It is not superfluous to check for system updates, since security and stability patches often contain patches for network drivers. → Version. MIUI/HyperOS, click on the system logo.

• 🧹 Clear the cache. DNS via the command line (required) ADB) or reboot.
• 📉 Remove unused applications that work in the background.
• 🔒 Check your phone for viruses and miners using the network.
• 📲 Reset network settings to factory if the problem persists.

Hardware factors and the influence of covers

Remember that physical factors can also affect the quality of the signal reception, such as the material of the smartphone case and protective accessories. Metalized cases or magnetic latch cases can shield antennas located around the body, reducing the level of the received signal by several divisions. If you notice a deterioration in communication after buying a new case, try to remove it and check the speed again.

In addition, damage to the antenna module after falling or getting moisture can lead to permanent communication problems that cannot be solved by software methods. In such cases, even with a full signal level, the Internet can be unstable or break down.

Also, it is worth considering that in some Xiaomi models, antennas are located at the bottom of the body, and a tight palm coverage in a horizontal position (for example, when playing) can block the signal.

💡

Physical obstacles and cover material can reduce internet speeds by up to 30%, even with full signal levels on the screen.
