How to improve the Internet on Xiaomi phone: from settings MIUI before selecting the operator

Slow internet on Xiaomi is a problem that every second owner of a smartphone of this brand faces, even flagship models like Xiaomi 14 Ultra or Redmi Note 13 Pro.+ Sometimes they slow down on the network, but they have to fly by the characteristics, and 90 percent of the time, it's not hardware constraints, it's the wrong settings. MIUI, Overloaded background processes or operator-side problems.

This article is not just a collection of tips to “reset the phone”; we will analyze the system settings that affect Internet speed, explain how to choose the optimal frequencies. 4G/5G, We'll show you how to get around the limitations of operators. MIUI 14/15 And they work on both the budget Poco and the premium Xiaomi, and if the Internet doesn't go faster after reading it, you'll at least know exactly what's causing it.

1. Diagnostics of the problem: why the Internet is slowing down on Xiaomi

Before optimizing the settings, you need to understand what exactly slows the connection. Xiaomi has three unique “diseases” that other brands do not:

• 🔄 Aggressive battery saving in MIUI Blocks background activity of applications, including data synchronization.
• 📡 Automatic network selection is often mistaken, clinging to congested frequencies. 4G free-rider.
• 🛡️ Built-in firewall MIUI It can block legitimate traffic, taking it as a threat.

To separate the phone from the operator’s problems, do the following:

1. Check the speed on Speedtest or Fast.com. Important! Test on both services - some operators artificially understate the results on Speedtest.
2. Compare metrics with another device (for example, a laptop over the same Wi-Fi or a computer). SIM-card).
3. Run ##4636### in the dialer and see the network type (LTE, NR for 5G) and signal strength (dBm). ⚠️ Note: If the Network Type is displayed HSPA+ instead LTE — Your phone is forced to slow down. MIUI, so-called operator restriction.

Optimizing the mobile Internet: network and frequency choices

Xiaomi defaults to network settings that are far from optimal, such as the phone can cling to an overloaded frequency of 2600 MHz (Band 7), even though there is a free 800 MHz (Band 20) with better coverage nearby.

2.1. Forced choice of network type (2G/3G/4G/5G)

MIUI It allows you to manually prioritize networks:

• 📶 The phone is constantly "jumping" between 4G and 3G, loses stability.
• 🚀 You need maximum speed (for example, for streaming in the 4K).
• 🔋 You need to save the battery by turning it off. 5G.

Instructions:

1. Go to Settings. → SIM-maps and mobile networks → [Yours. SIM] → Type of network.
2. Select: Only 4G (LTE) — Stability (recommended for most users). 4G/3G/2G (Cars – if there is a poor coverage in your area 4G. Only 5G (NR) — If you are in a safe zone, 5G And ready to sacrifice the battery.

Reboot the phone.

💡

If after changing the type of the network, the Internet disappeared completely - return the settings to the Auto and check whether the operator blocks manual selection (for example, Tele2 sometimes does this for tariffs without any tariffs). 5G).

Selection of preferred frequencies (Band Selection)

Xiaomi hides the possibility of manual selection LTE-It's a standard interface, but you can activate it through an engineering menu, and this is especially useful in densely populated areas where some frequencies are overloaded.

How to turn on:

1. Enter the dial code: ##4636## Select Phone Information.
2. Scroll down to Set Preferred Network Type and select LTE only.
3. Go back to the main menu of the engineering mode and select Band Selection.
4. Check the frequencies that your operator supports (see the table below).
5. Turn Off Radio, then Turn On Radio.

How to disable restrictions:

1. Go to Settings → Battery and Performance → Battery Mode.
2. Choose High Performance (on some models – No Limits).
3. Go back and select Battery Optimization. → Annexes.
4. Find apps that need a stable internet (like YouTube, Chrome) and choose for them.

3.2. setup of “Dual Applications” and VPN

Dual Apps (Dual Apps) in the MIUI It creates clones of messengers, but it also duplicates network traffic, which can slow down the Internet. If you're not using a second account on WhatsApp or Telegram, turn it off:

Settings → Annexes → Dual annexes → remove unnecessary clones.

Also check if it's on. VPN Some Xiaomi models (especially for the Chinese market) have built-in Mi. VPN, which can redirect traffic through servers in Hong Kong or Singapore, adding delays.

How to turn it off:

1. Settings → Connections and sharing → VPN.
2. Remove all saved configurations.
3. Turn off the automatic option VPN (if).

4. Firewall MIUI traffic restrictions

V MIUI There's a built-in firewall that blocks suspicious traffic by default, and the problem is that it sometimes misidentifies legitimate applications as a threat, like Torrent clients or the Internet. VPN-Services can be blocked without notice.

How to check and configure:

1. Go to Settings. → Memory. → Cleanup → Settings (cogs) → Special permits → firewall.
2. If there are any apps that are blocked, like uTorrent or ProtonVPN, unlock them.
3. Turn off the option to block suspicious activity (if enabled).

Also in MIUI There's a back-end traffic restriction for individual applications:

1. Settings → SIM-maps and mobile networks → Transfer of data → Background data transmission.
2. Make sure that the correct applications are ticked.

⚠️ Note: Some firmware (especially global) firewall MIUI It can conflict with antiviruses like Kaspersky or Avast. If the speed has increased after the firewall is turned off, remove the third-party antivirus.

5. Wi-Fi problems: how to get Xiaomi to “catch” the network stable

If mobile internet is working normally and Wi-Fi is “slowing down” or permanently shutting down – the problem may be the phone, router settings or their incompatibility. MIUI 13-14, Especially on budget models (Redmi) 9A, Poco M4 Pro).

5.1 Optimal Wi-Fi settings on Xiaomi

The following parameters will help stabilize the connection:

• 🔄 Disable automatic connection to open networks: Settings → Wi-Fi → Additionally. → Auto-connection to open networks → turn off.
• 📶 Enable Smart Switching (if available in your model): Settings → Wi-Fi → Additionally. → Smart switching Wi-Fi/mobile → This feature automatically switches to mobile internet if Wi-Fi is too slow.
• 🔒 Change Wi-Fi security mode: If the router is using WPA3, If the phone does not support it (relevant for older Xiaomi models until 2020), switch the router to the new one. WPA2-PSK.

5.2. Set up a router for Xiaomi

Some routers (especially TP-Link and TP-Link) ASUS) conflict with Xiaomi due to aggressive energy saving:

If Wi-Fi is still turned off after the changes, try fixing it. IP-Address for your Xiaomi in your router settings (DHCP Reservation: This will help avoid conflicts when reconnecting.

Make sure the router doesn’t overheat.|Change your Wi-Fi channel to a less busy one.|Turn off battery saving for Wi-Fi in settings MIUI|Update router firmware-->

6. Alternative ways to speed up the Internet

If standard methods do not help, try these non-obvious techniques:

Shift DNS-server

DNS from the operator or provider may be slow or block some sites:

• 🌍 Cloudflare: 1.1.1.1 and 1.0.0.1
• 🌐 Google DNS: 8.8.8.8 and 8.8.4.4
• 🛡️ AdGuard (blocks ads): 94.140.14.14 and 94.140.15.15

How to change DNS to Xiaomi:

1. Settings → Connections and sharing → Private DNS.
2. Select the host name of the private DNS provider.
3. Enter dns.google (for Google) or 1dot1dot1dot1.cloudflare-dns.com (for Cloudflare).

6.2.Use of applications to speed up the Internet

Some applications can optimize traffic:

• 🚀 Internet Speed Master – Clears the cache DNS and optimize TCP/IP.

⚠️ Warning: Do not install "Internet Optimizers" from unknown sources. Many of them contain malicious code or just show ads. Use only proven applications from Google Play.

Resetting network settings

If nothing works, do a complete network reset that will delete all stored Wi-Fi, passwords, and mobile network settings, but often resolves connection issues:

1. Settings → About the phone → Reset settings → Reset network settings.
2. Confirm the action.
3. Reboot your phone and reconnect.

💡

Network resetting is a last resort, and before that, export the list of saved Wi-Fi using applications like WiFi Password Viewer, so you don't have to re-enter passwords.

7 When the operator is to blame: how to get him to give normal speed

Sometimes the problem isn't with the phone, but with the carrier's restrictions, and here are the signs that the provider is to blame:

• 📉 Speed drops at certain times (e.g. in the evening).
• 🔄 When switching SIM-The card in another phone speed does not change.
• 📵 The operator artificially limits the speed after exhaustion of “unlimited” traffic.

What to do:

1. Check the real fare: Go to the operator’s personal account and make sure you don’t have hidden options connected (for example, the “Turbo button” at MegaFon, which eats money for “acceleration”).
2. Complain in support: Write to the operator’s chat with screenshots of Speedtest and the requirement to check the quality of services. According to the law “On communication” (Article 55), the operator is obliged to provide at least 10% of the declared speed.
3. Change. APN: Sometimes the operators change the settings. APN, But the phone keeps using the old ones. Update them: Settings → SIM-maps and mobile networks → [Yours. SIM] → Access points (APN) → Select an up-to-date profile or create a new one (settings can be found on the operator’s website).

If the operator refuses to solve the problem, consider changing the provider.According to Roskomnadzor for 2023, the average speed of the service is the same. 4G The operators were distributed in this way:

• MTS - 32 Mbit/s
• MegaFon - 28 Mbit/s
• Beeline - 25 Mbps
• Tele2 - 20 Mbps
