Slow page loading and constant video buffering are familiar to many Chinese smartphone owners, and Redmi or Poco users often find that when the same operator tower or router is used, neighbors get the signal faster, due to the features of the MIUI or HyperOS software shell, which require fine-tuning to work smoothly on Russian networks.
The problem lies not only in the hardware of the antenna module, but also in the software constraints that are set by default for the global market. In this article, we will discuss proven methods to get the most out of your connection without using third-party software. DNS-1.1.1.1 or 8.8.8.8 servers instantly eliminate long waits for a full signal in 90% of cases.
Before you get to the tricky stuff, you should rule out the trivial physical factors, check if the thick case is covering the antenna area, and make sure that the problem is not on the provider's side. If the tariff is okay, move to system optimization.
Basic diagnostics and resetting of network settings
The first step should always be to completely reset the accumulated errors in the operating system’s network stack, which over time accumulates cached connection data that may conflict with current signal reception conditions, a procedure that is secure and does not delete your personal files, contacts or photos.
To do the cleaning, you need to go to the settings menu and find the partition responsible for connections. Depending on the firmware version, the path may differ slightly, but the logic remains the same for all Xiaomi Mi and Redmi Note models.
- 📱 Open Settings and go to Connect and Sharing (or Wi-Fi).
- ⚙️ Find Reset Wi-Fi, Mobile Networks and Bluetooth at the bottom of the screen.
- 🔄 Click Reset button and confirm the action with the screen unlock code.
After restarting, the device is re-registered in the operator’s network, receiving a fresh IP-Address and update encryption protocols, which often solves the problem when the Internet "seems to catch" but the pages do not load.
⚠️ Warning: After resetting, you will have to re-enter passwords from all Wi-Fi networks and re-hide Bluetooth devices such as headphones or watches.
☑️ Checklist before reset
Optimizing DNS to speed up response
Standard. DNS-Servers that your mobile operator or home Internet provider automatically provides are often overloaded, and replacing them with faster and more reliable alternatives from Google or Cloudflare can significantly reduce server response time.
Modern versions of Android, including the shells from Xiaomi, have a built-in private DNS feature that runs on top of all connections, a more efficient method than prescribing addresses in the settings of each Wi-Fi network separately.
dns.googleOr an alternate address:
1.1.1.1To activate this function, go to Settings → Connection and sharing → Private DNS-Select the mode "Host Name of the provider" DNS» and enter one of the addresses above. The changes are effective instantly, no reboot is required.
This method is especially relevant for users who face blocking or slowing access to certain resources. Private DNS also encrypts your requests, increasing privacy when using open Wi-Fi hotspots.
💡
Use Cloudflare’s 1.1.1.1 app if manually entering the host name doesn’t work – it will automatically configure the optimal protocol for your region.
Access Point (APN) for 4G/5G
APNs are the gateway through which your smartphone connects to the carrier’s Internet, and often the automatic settings that come in SMS are not optimal for the current loading of cell towers.
Manually adjusting the protocol type allows the device to operate in a more modern data standard. You need to get into the menu of mobile networks and choose active. SIM-card if there are two.
| Parameter | Default value | Recommended value | Impact on speed |
|---|---|---|---|
| Protocol APN | IPv4 | IPv4/IPv6 | High (Priority 4G/5G) |
| Type APN | default,supl | default,supl,xcap | Medium (Volte stability) |
| MCC/MNC | Automatically. | Don't change! | Critical (network reset) |
To change, create a new access point by clicking on the plus or button "New APN." In the field "APN Protocol" select IPv4/IPv6, and in the field "APN Type" write xcap by comma. After saving, be sure to switch the air mode to reboot the communication module.
You don't have to experiment with MCC and MNC, which are country and operator codes, and if you make a mistake in those numbers, you'll lose all communication, and you'll only have to reset the access to the factory settings.
What happens if a new access point is not saved?
Hidden Engineering Menu and Network Priority
Redmi and Poco have a hidden menu that allows you to force the device to switch to 4G mode only, which is useful in areas of unstable reception, where the phone constantly “jumps” between 3G and 4G, losing connection.
To enter the test menu, dial ##4636## in the phonebook. If the code does not work (some global firmwares block it), you can use the Activity Launcher app to search for Testing activity.
- 📶 Select the phone information (Phone Information).
- 🔽 In the section "Install preferred network type" select LTE Only (Only) LTE).
- ⚠️ Remember that incoming calls may not work in this mode unless VoLTE technology is enabled.
Using LTE Only mode ensures that the phone will not waste battery life and time searching for a weaker 3G signal. However, by stepping out of 4G coverage, you will lose communication completely.
⚠️ Attention: “Only” mode LTE» Can block emergency calls (112, 102) In some regions, return the settings to «5G/4G/3G/2G (Auto” before visiting places with poor surface.
Removal of system debris and background activity restrictions
The MIUI shell is known for aggressive energy savings that can kill the processes responsible for connection stability. If a browser or messenger is not allowed to work in the background, reconnecting to the network can take several seconds.
Check your battery settings for key applications. Go to Settings → Apps → All apps, select your browser or game, and go to Saving Charge.
Set the value No Limits. This will allow the system to keep the network socket open all the time, which will eliminate delays when receiving notifications or downloading content in the background.
Regular storage cleaning also affects overall network performance: When the phone’s memory is crammed, the system has nowhere to place temporary exchange files, leading to network requests hanging over.
💡
Resolving background activity for the browser and messengers in the MIUI battery settings is a critical step for stable ping in games.
Using third-party utilities to reset TCP/IP
If standard methods don't work, you can use specialized applications that reset network sockets at a deeper level, and programs like the Internet Speed Booster or Network Signal Guru can reconfigure TCP/IP settings.
But be careful with apps that promise magic acceleration, and most of them just do the same setup reset we talked about above, but they show a lot of ads, and the best way to do that is to use ADB commands on your computer, but that requires skill.
A safer option is to use the Accelerate feature in Xiaomi’s built-in Security app, which closes the background traffic-consuming processes, freeing up the channel for the task you want.
In extreme cases, if the problem is only seen in a particular application, try changing its proxy settings. Sometimes the applications themselves assign the wrong proxy servers that slow down the connection.
