Modern smartphones Xiaomi Redmi line have a powerful hardware, but users often face a paradoxical situation: the flagship device “cuts” the connection speed or loads pages for a long time. This is not always the fault of the provider. Often the problem lies in the software limitations of the shell MIUI or HyperOS, which aggressively optimize background processes, along the way “soul” useful traffic. If your smartphone suddenly began to work slowly on the network, the first thing to do is to eliminate software failures before calling the operator.
In this article, we'll look at the non-obvious settings that are hidden from the eyes of the average user. You'll learn how to change DNS settings to speed up server response, reset the network settings to factory without losing data, and activate hidden engineering menus. Sometimes, just one right action is enough to make mobile Internet work at the full speed stated in the plan.
Note that some methods require care. Incorrect system protocol configuration can lead to temporary loss of communication. However, following our instructions, you can safely improve connection stability. Let's go from theory to practice and set your Redmi to maximum performance.
⚠️ Note: Before making changes to system settings, be sure to save important passwords from Wi-Fi networks, as resetting network settings will require re-entering them.
Diagnostics of current connection and frequency selection
Before you get into the deepest settings, you need to understand exactly what problem you are facing.The slow speed can be caused by congestion of the 2.4 GHz band, which is used by all neighboring routers, microwaves and Bluetooth devices. Xiaomi smartphone owners often do not even suspect that their phone is connected to a slow frequency, ignoring the fast 5 GHz.
Check your current speed with specialized applications, such as Speedtest by Ookla or the built-in Security Tester. If the scores are significantly lower than the ISP's stated rates, try forcefully switching to 5GHz. To do this, go to Settings → Wi-Fi, select your network (or click on the arrow next to it), and make sure that the network with the corresponding end in the name is given priority if the router broadcasts them separately.
It’s also worth checking if the traffic saving mode, which is often activated by default in newer versions of MIUI, is enabled, which can compress images and limit background synchronization, making the internet visually “sluggish.”
- 📶 Check the number of connected devices: if your router is connected to more than 10 gadgets, the speed on each of them will drop.
- 📡 Test distance: Get closer to the router to eliminate wall interference and interference on the signal.
- 🔄 Reboot router: banal shutdown of router power for 30 seconds often solves problems with the got stuck channels.
Shift. DNS-servers to speed up response
One of the most effective ways to speed up page loading and reduce ping in games is to change the page. DNS-The default servers are assigned by the providers, which are often overloaded or slow to process requests. DNS From Google or Cloudflare, you can significantly improve the network response on your Xiaomi Redmi.
In modern versions of Android and shell MIUI This can be done without obtaining root rights using the “Private” function. DNS». This method is encrypted. DNS-requests and directs them through a secure channel, which also increases privacy. You don't have to install third-party apps, everything is done through the system menu.
To activate, go to Settings → Connection and Sharing → Private DNS. The default is Auto. Select the option “Host Name of the DNS Provider” and enter the address of one of the fast servers. After saving, the phone can lose the network for a second, and then reconnect with the new settings.
| DNS Provider | Host address (domain) | Features |
|---|---|---|
| Google Public DNS | dns.google | High stability, universal availability |
| Cloudflare | 1dot1dot1dot1.cloudflare-dns.com | The fastest response, focus on privacy |
| Quad9 | dns.quad9.net | Blocking malicious domains at the DNS level |
| AdGuard DNS | dns.adguard.com | Blocking Ads and Trackers in Apps |
| OpenDNS | dns.opendns.com | Flexible content filtering settings |
💡
Use the address dns.adguard.com, if you want to not only speed up the Internet, but also get rid of intrusive advertising in the browser and some applications without installing programs.
Resetting network and mobile Internet settings
If a software failure has been accumulating for months, simple switching may not help, which requires a complete reset of network settings, which will not delete your photos, contacts or applications, but will clear all stored Wi-Fi passwords, Bluetooth pairs and mobile access point (APN) settings.
Often the problem lies in the incorrect settings of the access point, especially if you recently changed the access point. SIM-The system could have kept the old parameters. APN, The reset will return these values to the factory recommended by the manufacturer.
To reset, go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. Click on Reset button at the bottom of the screen. The device can request an unblock password confirmation. After the reset, you will need to re-enter your home Wi-Fi password.
☑️ Checklist before network reset
Once you restart, the system will re-register on the operator's network. If mobile Internet speeds remain low, check the access point settings manually. → SIM-maps and mobile networks → (Yours. SIM) → Access points (APN). Make sure you have the right profile, or create a new access point with the options obtained on your operator’s website.
⚠️ Warning: Do not remove the operator's standard access points unless you are sure of their purpose. APN from scratch, copying data from the official website of the provider.
Engineering menu and choice of preferred network type
For advanced users who want to make the most of Redmi, there is an engineering menu that allows you to force the modem to 4G-only (LTE) mode, preventing it from sliding down to 3G or 2G in areas of insecure reception, often addressing the problem of the “blinking” Internet.
Unlike older versions of Android, modern MIUIs often block access to the full engineering menu, but you can try using codes or test menus. Type ##4636## in the dialer. If the menu opens, select Phone Information.
In the list that opens, look for the option “Set Preferred Network Type” (Set Preferred Network Type). By default, it can be “LTE/TD-SCDMA/GSM”. For maximum speed, select the option that contains LTE Only.
What happens if you choose LTE Only?
It is important to understand that incoming calls may not work in LTE Only if your carrier does not support VoLTE (Voice over LTE), in which case the caller will sound “Subscriber is not available.” To return to normal mode, simply restart your smartphone or select “LTE/TD-SCDMA/GSM (auto connect)” from the menu.
Optimizing Applications and Background Processes
MIUI is famous for its aggressive energy-saving system, which can freeze background processes, including those that are responsible for connection stability, and if messengers arrive late and cards are loaded with jerks, you need to set up autostart and work in the background.
Go to the Security → Battery → Settings app. Make sure that you don’t activate UltraSaving, which limits background activity. Also, check the list of apps: find the browser or navigator you use most often and allow them to “Start” and work in the background without restrictions.
Another important aspect is to turn off the Wi-Fi Assistant feature, which is designed to switch the phone to mobile Internet if Wi-Fi is weak, but in practice it often causes constant reconnections and delays, and you can turn it off in Settings → Wi-Fi → Wi-Fi Assistant.
- 🚀 Turn off Game Acceleration for background apps if they are not in use right now to free up the channel.
- 📉 Limit background data transfers for heavy applications (social networks, videos) that you are not currently using.
- 🔌 Check if the Data Savings mode is enabled in the settings SIM-Maps that block content updates.
💡
Aggressive battery optimization in Xiaomi is often the main reason for the unstable internet: allowing background work for key applications solves 80% of the problems.
Hardware factors and the influence of covers
The antennas in Xiaomi Redmi smartphones are located around the perimeter of the body, often in the lower and upper parts. Dense metal cases, magnetic clasp cases or thick protective glasses can shield the signal, reducing the speed of data transfer.
Try to take off your case and run a speed test, and if the difference is significant, it means the accessory is a problem. SIM-Older cards that are over 5 years old may not support new encryption and frequency standards 4G+. Replacement SIM-cards to the operator for a new (USIM) often performs miracles.
In rare cases, the problem may be in the oxidation of contacts. SIM-Remove the tray, wipe the contacts of the card with soft dry cloth and set back. Make sure the tray sits tight and has no backlash.
