How to speed up the Internet on Xiaomi: from basic settings to hidden chips MIUI

Slow internet on Xiaomi’s smartphone is a problem that almost everyone faces. Even flagship models like the Xiaomi 14 Ultra or POCO F6 Pro sometimes slow down when loading pages, buffering videos or playing online, and the reasons can lie in the settings of the device itself, as well as external factors: an overloaded operator network, outdated firmware or even incorrect parameters of the communication module.

In this article, we’ll look at 10 proven ways to speed up the Internet on Xiaomi, from simple tricks like changing Wi-Fi range to deep optimization of system parameters. We’ll focus on hidden MIUI settings that the manufacturer doesn’t advertise, but can give speeds up to 30-40%. And we’ll also find out why even on top-end models like the Redmi K70 Pro, the speed can sag because of smart energy-saving algorithms.

1. Real speed check: how to know where the bottleneck is

Before you can optimize something, you need to understand where the brakes are.

• 📱 Measure your speed on your smartphone via Speedtest or FAST.com (from Netflix). Compare it to other devices on the same network.
• 📶 Check the signal level: in Settings → SIM-Maps and mobile networks, look at the network indicator. -100 dBm 4G/5G), carrier-coating.
• 🔄 Reboot your router and smartphone – sometimes it solves up to 50% of the problems with the “suspend».

If other devices (laptop, tablet) are running at normal speeds and Xiaomi isn’t, the phone settings are to blame, and if it’s slow everywhere, the router or provider is the problem.

⚠️ Note: If the speed on Wi-Fi on Xiaomi is below 10 Mbps, and on other devices – 50 Mbps+ Mbps is likely to be connected to an overloaded 2.4 GHz band. The solution is in the next section.

2. Wi-Fi Optimization: Selection of Range, Channel and Standard

Most routers broadcast simultaneously on two bands: 2.4 GHz (long-range but slow) and 5 GHz (fast but with less coverage). By default, Xiaomi can cling to 2.4 GHz even if 5 GHz is available.

1. Open the Settings. → Wi-Fi.
2. Tap on the name of your network → Change the network.
3. Turn on the option Additional and select 5GHz manually (if the router supports).
4. Activate WPA3 in your router settings – this protocol is faster and safer than WPA2.

If you don't have 5GHz, check your router's settings: it's probably off, and you should change your Wi-Fi channel manually (via the router's web interface) to avoid interference from neighboring networks. Optimal 5GHz channels are 36, 40, 44, 48 (the least overlapping).

For Xiaomi models with Wi-Fi 6 support (Xiaomi 13T Pro, Redmi Note 12 Pro+ and later), include this standard in your router settings. It reduces latency and increases speed when connecting multiple devices.

💡

If your router doesn’t support 5GHz, but you have Xiaomi with dual-band Wi-Fi, buy a low-cost repeater (like Xiaomi Mi Wi-Fi Range Extender Pro) – it relays the signal on both bands.

3. Mobile Internet setup: APN, network mode and SIM priority

If speed issues occur on a mobile network, check the APN access points. Incorrect settings can limit speeds to 3G even if 4G/5G is available:

• 📌 Go to Settings. → SIM-maps and mobile networks → [yours SIM] → Access points (APN).
• 🔍 If there are several profiles, select the one that matches your operator (for example, Internet.beeline.ru for Beeline).
• ⚙️ If the profile is one but the speed is low, create a new one manually (options) APN You can find the operator's website).

Check the network mode:

1. Open the Settings. → SIM-maps and mobile networks → [yours SIM] → Type of network.
2. Choose 4G (preferably) or 5G (if supported).The Auto option sometimes gets stuck on 3G.
3. Activate VoLTE and VoWiFi (if available) to improve connection stability.

For two-symbol models (POCO X6 Pro, Redmi Note 13 Pro+) Establish priority over the main SIM-maps in Settings → SIM-maps and mobile networks → Priority SIM-data-card.

⚠️ Attention: On some firmware MIUI (especially global) option Only 4G In this case, it will help to reset the network settings (see section 5) or install custom firmware (for example, Xiaomi.EU).

4. Hidden MIUI settings: how to turn on "maximum performance mode"

Xiaomi hides some options that can speed up the Internet significantly, including High Performance Mode, which disables power saving for network modules.

1. Open the Settings. → The phone.
2. Tap 5 times on the MIUI version until you become a developer!
3. Go back to the Settings → Additional → Developer settings.
4. Find options: Turn off absolute charge savings (turn off); Background restriction for networks (turn off); Network idle optimization (turn on).

Another hidden parameter is Fast Data Transfer, which uses the maximum speed of LTE/5G, but can drain the battery faster, and it is enabled in the same Developer Settings called Install preferred network type (select LTE only or NR/LTE for 5G).

For models with Qualcomm Snapdragon (e.g. Xiaomi 13, POCO F5), there is another trick: type in the phone dial code ##4636##, select Phone Information, and install Set preferred network type on LTE only or NR/LTE/TD-SCDMA/GSM (for 5G).

Disable "Absolute charge saving"

Enable "Optimize the network in standby mode"

Install "Preferred Network Type" on LTE/5G

Disable "Background Limitation for Networks"

Reboot the phone-->

5. Network Resetting: When It Really Helps

If all the previous methods didn't work, it's time for a hard reset, which removes all the stored Wi-Fi networks, passwords, APN settings, and resets the mobile Internet settings to the factory settings.

1. Open the Settings. → SIM-maps and mobile networks.
2. Tap Network Settings Reset (or Wi-Fi, Mobile Network, and Bluetooth Reset on newer versions of MIUI).
3. Confirm the action and restart the phone.

If the update doesn’t work, try to roll back to a stable version (e.g., from MIUI 14 to MIUI 13).

1. Download the necessary firmware from the official website.
2. Rename the file to update.zip and place it in the root of the phone’s memory.
3. Press Volume Up + Power to log in to Recovery, and select Install update.zip.

Also check the modem version (radio module) for this type in the terminal (via Termux):

getprop gsm.version.baseband

If the modem version is outdated, update the firmware or reflash the modem separately (instructions are available on 4PDA).

💡

Updating your firmware is the most reliable way to fix software speed limits, and even if the update doesn’t mention the network in the description, new modem drivers can significantly improve performance.

7.DNS optimization and routing: how to get around operator restrictions

Sometimes the slow speed is not due to the connection itself, but to the DNS-servers that your carrier or provider uses, which can be overloaded or intentionally inhibit access to certain sites. DNS faster:

• 🌍 For Wi-Fi: Open Settings → Wi-Fi → tap your network. Choose Change the network. → Additionally. → Settings IP → Static, in the fields. DNS 1 and DNS 2 Enter: 1.1.1.1 (Cloudflare) 8.8.8.8 (Google) 94.140.14.14 (AdGuard, blocking ads)
• 📡 For mobile: Install 1.1.1.1: Faster Internet. Turn on Warp to encrypt traffic and speed up routing.

Another way to speed up loading is to disable IPv6 (if your carrier doesn’t support it properly).

1. Go to Settings. → SIM-maps and mobile networks → [yours SIM] → Access points (APN).
2. Select your APN and enter IPv4 (instead of IPv4/IPv6) in the APN protocol field.

If you use YouTube or Netflix a lot, try changing the Google Play region (via VPN), some of the servers of these services in Russia and the CIS artificially limit speed.

8. Hardware restrictions: when the "iron" is to blame

If all software methods have been tried and the speed is still low, the problem may be in the hardware:

• 📡 Antennae Wi-Fi/4G: In cheap models (Redmi) A2, POCO C50) We use weak antennas that don't catch the signal well, so the solution is an external antenna (for example, through an adapter). MHF4).
• 🔋 Overheating: Heating above 45°C is triggered by trottling, and the speed drops. CPU-Z.
• 🛠️ Module damage: If the speed drops sharply after falling or getting moisture, the antenna contact may have moved away or the chip is damaged. RF (Diagnostics are required in the service).

To check the hardware:

1. Enter the dial number ##4636## → Phone information.
2. If the ASU (signal level) is less than 10 and dbm is less than -110, the problem is in the antenna or SIM card.
3. If it's HSPA+ instead of LTE, the modem doesn't catch 4G (possibly due to damage).

If you suspect a hardware malfunction, try inserting SIM-If the speed is normal, the problem is your Xiaomi.

💡

Hardware malfunctions (especially after falls or moisture) are the most difficult cause of low speed to diagnose. If all software methods have not worked, contact the service to check the antennas and communication module.
