Modern Xiaomi and Redmi smartphones are equipped with powerful communication modules that can support high data rates in 4G and even 5G networks. However, owners often face a situation where video content is buffered for a long time, and the pages of sites are opened in jerks. This can be caused by software failures, incorrect network settings or physical location relative to the operator's base station.
Before you blame the provider, it is worth conducting a comprehensive diagnostic of the device. Optimizing the settings of the MIUI or HyperOS operating system often allows you to squeeze the most out of the available signal. We will consider both standard methods and advanced engineering solutions to improve the quality of the connection.
In this tutorial, we will discuss specific steps that will help stabilize ping in games and increase the speed of downloading files. Attention: some actions require moving to the engineering menu, so follow these instructions carefully.
Basic diagnostics and network coverage verification
The first step is always to check the current state of the network, and often the problem is not the phone, but that the device is stuck on an overloaded tower or is running in 3G mode instead of 4G.
If you see the H icon+ or 3G, You can't physically access high speeds, you have to force the modem to switch. โ SIM-maps and mobile networks โ Choose yours. SIM-map โ Type of network.
Preferably 4G or 5G, if your fare and carrier coverage support this, sometimes it helps to switch on the flight mode for 10-15 seconds, which forces the module to re-register on the network and choose the nearest base station.
- ๐ก Make sure that in the settings of the access point (APN) No outdated parameters of your operator are prescribed.
- ๐ Reboot your smartphone if it has not turned off more 3-4 Days to Reset Network Process Cache.
- ๐ Check your operatorโs coverage map at your current location, you may be in a blind spot".
โ ๏ธ Warning: If you are on the move (car or train), frequent base station changes can cause short-term communication interruptions.
Adjust Access Points (APN) to Accelerate
One of the most effective methods is manually configuring or resetting APN (Access Point Name) access points. Operators periodically update their gateways, and the old settings in the phone may not work correctly, creating unnecessary delays when routing traffic.
To get to the desired menu, use the Settings path. โ SIM-maps and mobile networks โ (Yours. SIM) โ Access points (APN). In the list that opens, click the Reset button at the bottom of the screen or create a new access point with the options recommended by your operator.
In some cases, changing the type of APN helps. It's default,supl. You can try adding a dun parameter or changing the protocol to IPv4/IPv6 if you only have one, and it often solves the problems with connecting certain services.
โ๏ธ Checklist settings APN
After making changes, be sure to turn mobile data on and off. The system should apply new routing options. If the speed has not changed, return the default settings, as an incorrect APN can completely deprive you of access to the network.
Shift. DNS-servers to speed up response
Standard. DNS-servers that are automatically issued by the carrier are often overloaded or slow to process requests, replacing them with faster public servers such as Google. DNS Cloudflare can significantly reduce response time (ping) and speed up the opening of โheavyโ sites.
On modern versions of Android and the MIUI/HyperOS shell, this can be done without installing third-party applications. Go to Settings โ Connection and Sharing โ Private DNS. Select the option โHost Name of the DNS providerโ and enter the server address.
The following addresses are considered the fastest and most stable:
- ๐ Googleโs dns.google servers provide high stability.
- โก 1dot1dot1dot1.cloudflare-dns.com โ Cloudflare servers often give the best ping in games.
- ๐ก๏ธ dns.adguard.com โ blocks ad trackers at the level DNS, This also speeds up the loading of pages.
Once you enter the address, click "Save." Check the Internet will be automatically checked. If the web pages stop opening, return the setting to "Auto" or "Disabled".
Why does DNS affect speed?
Engineering menu and choice of preferred frequency
For advanced users, there is access to a hidden engineering menu where you can control the radio module at a deeper level, which allows you to, for example, prevent the phone from switching to slow frequencies or make it search only for certain LTE bands.
To log in to the menu, use the standard code ##4636## in the Phone app. If the code is not working (it is blocked on some firmware), you can use the Activity Launcher app or special utilities from the Play Market like 4G LTE Switcher.
In the menu that opens, select "Phone Information." Go to "Prefer to network type." Here you can select LTE Only mode. Be careful: this mode may not work incoming calls unless VoLTE technology is enabled.
| Network mode | Description | Impact on speed |
|---|---|---|
| LTE Only | Only 4G network. | Maximum speed, but no calls can be made |
| NR/LTE/GSM | 5G/4G/3G car | Balance of speed and coverage (recommended) |
| GSM Only | Only 2G. | Very slow, only for calls and SMS. |
โ ๏ธ Note: Experimenting with settings in the engineering menu (4636) can lead to loss of communication. If you are not sure about your actions, it is better to limit yourself to the standard settings in the system menu.
Background cleaning and optimization of MIUI system
Often, the slow Internet speed on Xiaomi is due to the fact that background applications are actively consuming traffic. Synchronizing photos to the cloud, updating applications or downloading large files in instant messengers can โstrangleโ the main data stream.
Check the data usage statistics. Go to Settings โ Data usage โ Usage statistics. Here you can see which applications are most consuming traffic. For unnecessary background processes, you can limit data transfer.
Itโs also worth turning off the Wi-Fi Assistant feature if itโs not working properly, which tries to speed up the internet by switching to a mobile network when Wi-Fi is weak, but in practice often creates cyclical switches and connection breaks.
- ๐งน Clear the cache of the browser and system services of Google Play through the menu "Security" โ "Cleanup".
- ๐ Turn off auto-update apps in Play Market for Mobile Data mode".
- ๐ Check the power saving mode: in Ultra mode, the system can limit the operation of the network module.
๐ก
Use the built-in Security app on Xiaomi. There's an Acceleration feature that closes the background processes and can temporarily free up resources for network activity.
Resetting network settings as a radical solution
If software failures accumulate, a complete reset of network settings may be required, and this action will return all connection settings (Wi-Fi, Bluetooth, mobile network) to factory values.
Resets can be done via the Settings path โ Connection and Sharing โ Reset Wi-Fi, mobile networks and Bluetooth. Click the Reset button at the bottom of the screen and confirm the action with the unlock password.
Once rebooted, the phone will search for networks as new, youโll have to re-enter Wi-Fi passwords and possibly reconfigure APN access points if they donโt automatically pull up from the carrier.
โ ๏ธ Note: After resetting your network settings, all stored Wi-Fi passwords will be deleted. Make sure to remember the password from your home network, or write it down before starting the procedure.
๐ก
Resetting network settings eliminates configuration file conflicts that may have occurred after a firmware update or change SIM-map.
Effect of the cover and the physical state of the antenna
The physical aspect is also important: antennas in Xiaomi and Redmi smartphones are often built into the case, and tight cases with metal inserts, magnetic holders, or simply very thick silicone can shield the signal, reducing the speed of reception.
Try to remove the case and check the Internet speed at the same point, and if the rates have increased, then the accessory was the problem, and it is also worthwhile to wipe the upper and lower faces of the phone from pollution and grease, which also affect dielectric permeability.
In rare cases, the cause may be oxidation of contacts SIM-Remove the tray, wipe the contacts of the card with a soft cloth and make sure that it sits tightly in the slot.
