Slow internet on a modern smartphone is not just an annoyance, but a real obstacle to productive work and quality leisure. Owners of Xiaomi, Redmi and POCO devices often face a situation where the operator’s stated speed does not coincide with real performance in the browser or applications. This can occur for a variety of reasons, from banal cache overflow to incorrect settings of the system parameters of the MIUI shell or HyperOS.
Before you blame the provider or think about buying a new gadget, it is worth conducting a deep diagnostic of the software part of the device. Resetting the network settings to factory settings eliminates more than 60% of problems with an unstable connection without deleting your personal files, contacts or photos. In this article, we will discuss a set of measures that will help you to get the most out of your plan and hardware.
Optimization requires a consistent approach. You can't just change one parameter and expect a miracle, you have to look at the whole system. We'll go from simple signal checks to advanced manipulation of the system. DNS-And be prepared for some of the settings that you're going to need to be careful, but the result is worth it.
Diagnostics of current connection and signal analysis
The first step is always to make an objective assessment of the situation. Many users confuse the signal level (the number of sticks in the status bar) with the real data rate. A full scale can show a powerful signal from the base station, but the channel can be heavily congested by other subscribers or have high ping time.
Pay attention to the type of network you use. → SIM-maps and mobile networks → The preferred network type must be selected 5G/LTE, If it's supported by your SIM card and coverage in the area, if the phone is constantly switching between 3G and 4G, Don't wait for a stable connection, in such cases, it's better to force the regimen only. LTE, avoiding constant reconnection.
It’s also worth checking if the traffic saving mode is activated, which can artificially limit the background activity of applications. Go to Settings → Connection and Sharing → Traffic Saving and make sure the feature is turned off or configured correctly for your needs. Sometimes the system itself blocks background data transfer for heavy applications, considering this optimization.
- 📶 Check the signal level at different points in the room – it can be much higher at the window.
- 📱 Make sure you're on SIM-The map does not end with a high-speed traffic package.
- 🔄 Reboot your smartphone to reset temporary network errors and re-register on the network.
- 🛑 Turn it off. VPN-services if they are running in the background, as they often cut speed.
⚠️ Warning: If you are in the area of uncertain reception, turn on the "Only" mode LTE» This can cause a complete loss of communication if the cover 4G This is not the point at which you're not.
Configure Access Points (APN) for maximum speed
One of the most effective but often ignored settings is the correct configuration of APN access points (Access Point Name). Communication operators often provide standard settings that may not be optimal for specific conditions or models of Xiaomi phones. Proper setting of APN allows you to eliminate delays in establishing a connection and improve ping stability.
To access these options, go to Settings path → SIM-maps and mobile networks → (Choose yours. SIM) → Access points (APN). Here you'll see a list of available profiles. Don't rush to delete a standard profile, you'd better create a new one by clicking on the plus or the "New Access Point" button. In the "Name" field, type in any name, such as FastInternet, and in the "Access Point" field (APN)» Enter the value recommended by your operator (often internet or mts, beeline, etc.).
In the advanced settings of the new access point, look for the "APN Type" field and make sure that it says default,supl. You can also try changing the APN protocol to IPv4/IPv6 if only one of them is selected. After saving the settings, be sure to turn on and off the flight mode or restart the device to make the changes take effect.
☑️ Checking settings APN
It is worth noting that there is no universal secret APN for all operators, and that using someone else’s settings can cause the Internet to stop working altogether or double-tariff traffic. Always check your carrier’s official data before making changes to system settings.
Optimization DNS-servers to speed up response
Page loading speed depends not only on the width of the channel, but also on the time it takes for the domain to convert into a new channel. IP-The standard address. DNS-ISP servers are often slow or congested.Switch to fast public DNS, Google-like DNS Cloudflare can significantly speed up the response of the system and the opening of sites.
On modern versions of Android and MIUI/HyperOS shells, you can do this without getting root permissions. Go to Settings → Connection and Sharing → Private DNS. The default is Auto. Select the "Host Name of Private DNS Provider" option and enter the fast server address.
dns.googleAlternatively, Cloudflare offers:
1dot1dot1dot1.cloudflare-dns.comOnce you enter the address, save the settings. Changes apply instantly. You can test the speed of opening sites before and after changing the DNS using incognito mode in the browser. This is especially true for owners of low-end Redmi models, where the processor can process requests to overloaded servers more slowly.
| DNS Provider | Address (Host) | Features |
|---|---|---|
| Google Public DNS | dns.google | High stability, global coverage |
| Cloudflare | 1dot1dot1dot1.cloudflare-dns.com | Emphasis on privacy and minimal ping |
| Quad9 | dns.quad9.net | Blocking phishing sites at the DNS level |
| OpenDNS | dns.opendns.com | Flexible Content Filtering Settings |
What if the Internet disappeared after the DNS change?
Resetting network settings and cleaning the cache
Accumulation of temporary files and errors in network modules is a common cause of slowing down over time. If you haven't updated your firmware or actively tested various Wi-Fi networks, digital debris could accumulate in the system. Resetting network settings returns all the connection parameters to the factory state.
It's important to understand the difference between completely resetting your phone and resetting only your network settings. The second option is secure for your data. It will delete stored Wi-Fi passwords, paired Bluetooth devices and mobile network settings, but leave contacts, photos and apps in place. This operation is performed through the Settings menu → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth.
Once reset, you need to re-enter Wi-Fi passwords and re-save your smartwatch or headphones, but it often solves problems with hanging connections and low download speeds, and re-negotiates parameters with base stations and routers, often leading to a better channel.
- 🗑️ Remove all stored Wi-Fi networks and passwords.
- 📵 Resets Bluetooth settings and breaks pairing with devices.
- 📡 Returns the mobile network settings and APN factory-value.
- ✅ Does not affect personal files, apps and Google accounts.
⚠️ Warning: Before performing a reset, make sure you remember passwords from important Wi-Fi networks, as it will not be possible to recover them from your phone settings after this procedure.
The Effects of Background Processes and System Constraints
The MIUI shell is known for its aggressive energy-saving policies that sometimes work against the user.The system can limit the background activity of applications, considering them “glutty”, which leads to delays in receiving notifications or slow loading of content in the background.
Go to Settings → Applications → All applications, select the service you want (such as messenger or navigator) and go to Battery. Set No Limits mode. This will allow the application to freely use the network resource when necessary. Also, in the Security menu → Battery, you can turn off sleep mode for mission-critical programs.
Xiaomi system services are also not to be forgotten. MSA (MIUI System Ads) and other ad units can consume traffic in the background. While completely disabling them requires more in-depth knowledge, you can limit data transfers to them. Go to Settings → Applications → All applications → (three dots at the top) → Show system processes, find msa and limit background data transfer.
💡
Turn off autoplay of videos on social networks (Vkontakte, Instagram, Telegram) This will save up to 30% of traffic and speed up the loading of the tape, as the phone will not waste resources on preloading heavy content.
Hardware limitations and frequency range selection
Budget Redmi models or older flagships can support fewer bands (Bands) compared to top-end models. If your phone does not support Band 7 or Band 38, which are often used by carriers to offload networks in cities, the speed will be lower, even with a full signal.
You can check the frequencies you support from the engineering menu. Type ##4636##. From the menu that opens, select Phone Information and see the list of supported bands. Compare them to your carrier's frequencies. If the frequencies are not on the list, you can't programmatically speed up the Internet, just changing the operator or phone will help.
Also affecting speed are antennas and the presence of a case: dense metal or magnetic covers can shield the signal, reducing the effective connection speed. Remove the case and check the speed again, sometimes the problem lies in the accessory, which you consider protection, and it is the source of interference.
💡
Hardware frequency support is a physical speed limit that software settings can't overcome. Always check the phone's specifications against the operator's frequencies.
