Slow internet on a smartphone is always an annoyance, especially when you own a powerful Xiaomi device that can do much more. Often the problem lies not in the operator’s weak plan or overloaded router, but in the incorrect system settings that the manufacturer defaults. Understanding how the network module in the shell of MIUI or HyperOS works allows you to squeeze the most out of the available connection.
In this article, we will look at the proven methods that actually work on the devices of this Chinese company, we will touch on both the software tweaks and the physical aspects of signal reception. Network optimization requires a comprehensive approach, so you should not limit yourself to switching air modes.
Before we go to radical measures like resetting, it's worth checking the basics, and sometimes just changing a single digit in the configuration of the access point is enough to make the packet data fly at a new speed.
Diagnostics of current connection and identification of bottlenecks
The first step to solving this problem is always accurate diagnosis: don't rely on subjective feeling "slowly", use objective data, run a speed test through specialized applications like Speedtest by Ookla or Fast.com to get the download and return numbers (Download) (Upload).
Pay attention to ping. High latency often affects comfort more than low download speed. If the ping jumps, the problem may be channel congestion or physical obstruction. Wi-Fi signal may be displayed full, but the connection quality will be low due to interference.
⚠️ Note: If the internet speed is low only in certain applications (e.g. YouTube or Instagram), the problem may be on the server side of these services or in optimizing them for your region, not in the phone settings.
Check to see if the traffic saving mode is activated, which can artificially limit background activity and browser speed.In MIUI settings, this option is sometimes turned on automatically when the battery is low.
Setting up an APN access point for mobile networks
One of the most effective ways to speed up the Internet on Xiaomi is to manually configure the Access Point (APN). Communications operators often provide standard settings that are not always optimal for modern 4G/LTE networks. Creating a new access point with the right protocol parameters can significantly improve connection stability.
To enter the settings menu, go on the Settings path → SIM-maps and mobile networks → Choose yours. SIM-map → Access points (APN). Here you'll see a list of existing profiles. Don't edit them, create a new one by clicking on the plus at the bottom of the screen.
☑️ Setting up a new access point APN
In the window that opens, you need to fill in the fields “Name” (any, for example, FastInternet) and “Access Point (APN).” For most Russian operators, you need to enter the Internet in the APN field. However, the key point is to configure the protocol type. Find the “APN type” item and make sure that default,supl. In some cases, changing the APN protocol type to IPv4/IPv6 helps.
| Parameter | Value for adjustment | Description of the impact |
|---|---|---|
| Name. | Fast 4G | arbitrary name for |
| APN | internet | Main gateway of the operator |
| Protocol APN | IPv4/IPv6 | Priority of modern networks |
| Type APN | default,supl | Standard traffic and GPS |
Once you have entered all the parameters, be sure to click the "More" button (three dots in the corner) and select "Save." Then activate the profile you created by ticking it against, and rebooting the device after this procedure is optional, but desirable for full application of the changes.
Optimizing Wi-Fi: Frequency and Channels
In the era of dense apartment buildings, the 2.4 GHz band is often overloaded with neighborhood routers and appliances. If your router and Xiaomi smartphone support the 5 GHz standard, switching to this frequency is the best way to speed up the Internet. The data speed in the 5 GHz band is much higher, and the interference level is minimal.
But there's a nuance to the 5GHz band: it's worse at penetrating walls. If you're far from the router, the phone can cling to a weak 5GHz signal instead of switching to a more stable, albeit slow, 2.4GHz, in which case Smart Network Choice or manual priority helps.
It is also worth paying attention to DNS-servers. DNS The Wi-Fi settings on Xiaomi (click on the gear next to the name of the connected network) can be used to prescribe static DNS. Use trusted servers such as those from Google (8.8.8.8) or Cloudflare (1.1.1.1).
For advanced users, a hidden engineering menu is available, where you can see detailed connection information. Enter the dialer code ##4636##, select Wi-Fi Information and check the link speed. This is the real connection speed between the phone and the router, which is independent of the ISP's speed.
Resetting network settings and working with cache
Network configuration errors are a common cause of sudden speed drops, and over time, Android can become a conflicting system. IP-Addresses or errors in routing tables: Network resets all settings back to factory values, removing stored Wi-Fi passwords and Bluetooth settings, but often it is the only working solution.
You can reset via Settings → Connect and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. Once confirmed, the phone will reset the network modules. This action is safe for your personal data (photos, contacts), but you will have to re-enter passwords from Wi-Fi networks.
⚠️ Note: Before resetting your network settings, make sure you remember passwords from important Wi-Fi networks, as it will be impossible to recover them from your phone’s memory after the procedure.
Also, clear the cache of the system services responsible for communication. Go to Settings → Applications → All applications, find the Settings list (the gear icon) and clear its cache. You can also clear the cache of the Phone and Messages application if these services are experiencing problems.
Sometimes, the Wi-Fi Assistant function helps, which is designed to automatically switch the phone to mobile Internet if the Wi-Fi signal is weak, but in practice it often works incorrectly, causing constant reconnections and breaks in the session, which creates the illusion of slow Internet.
Use of engineering menus and hidden codes
Xiaomi smartphones have powerful diagnostic tools hidden from the average user. The engineering menu allows you to force switch network modes, which is especially true in areas of uncertain reception, where the phone “jumps” between 3G and 4G, losing speed.
Enter ##4636## in the dialer. If the menu doesn't open, your firmware version may block that access and you'll need to install a special app from the Play Market (such as Force LTE Only).
Find the option "Tune your preferred network type." The default is "NR/LTE/TD-SCDMA/GSM." If you have a bad 5G (NR) catch in your neighborhood, but a good 4G, your phone can waste resources searching for 5G, reducing overall performance. Forced switching to LTE only (4G only) often stabilizes speed and reduces ping in games.
- 📶 NR/LTE/GSM — The phone chooses the best network (recommended for the city).
- 🚀 LTE only — 4G, useful for stability in games, but incoming calls may not work (without VoLTE).
- 🐢 GSM only - regime 2G, used only for emergency battery saving or in areas where only catches EDGE.
- 🌐 NR only - only - only - 5G, It only makes sense if the fifth generation is perfectly covered.
In this case, you will only be able to receive calls or not be able to do so at all until you return the standard settings.
Third-party annexes and DNS-tweakers
If the built-in tools are not enough, specialized utilities come to the rescue. DNS Changer allows you to change quickly DNS-This is especially useful when using public Wi-Fi networks in cafes or shopping malls where ISPs are used. DNS They can filter or slow down traffic.
There are also optimization applications, such as Internet Booster & Optimizer, which work by clearing the DNS cache, closing background traffic-consuming processes, and pinging servers to choose the optimal route, and while they do not work miracles, when combined with other measures, they have a noticeable effect.
However, be careful with applications that promise “200% internet speed”; most of them simply run animations or perform a standard connection reset that you can do yourself. Root rights open access to hosts system files and TCP/IP configurations, allowing you to change the size of the reception buffer, but this requires high skill and can lead to unstable system operation.
⚠️ Warning: Avoid installing accelerators from unverified sources. Often, these programs contain aggressive advertising or miners that, on the contrary, will slow down your Xiaomi and consume traffic.
For advanced users willing to experiment, there is the option of editing a build.prop file (requires Root). Adding strings like net.rmnet0.dns1=8.8.8.8 can prescribe system-level DNS for all interfaces at once. But remember, any error in this file can lead to a bootloop (cyclical reboot) of the device.
Physical factors and the influence of covers
Don't discount the trivial physical reasons: antennas in modern Xiaomi smartphones are located around the perimeter of the case. If you use a massive case with metal inserts, magnetic latches or just a very thick silicone, it can shield the signal.
Try to remove the case and run a speed test, the difference can be significant, especially in low signal conditions, and it also matters how you hold your phone: palm-closure of the lower or upper edge (where antenna lines are often located) can cause the signal to fade. 10-15%.
In conclusion, speeding up the web on Xiaomi is a process of finding a balance between software settings and physical conditions. Start with setting up APN and DNS, check Wi-Fi frequencies, and then move on to engineering menus. A comprehensive approach is guaranteed to improve the quality of your connection.
