How to distribute the Internet with Xiaomi Redmi Note 9: all the ways and subtleties of setting up

The distribution of Internet from the smartphone Xiaomi Redmi Note 9 is a useful feature that helps when traveling, in the country or when the main router suddenly stopped working. Despite the apparent simplicity, many users face problems: the access point does not turn on, devices do not connect, speed leaves much to be desired. In this article, we will analyze all possible ways to distribute the Internet from your Redmi Note 9, including hidden settings MIUI, optimization for games and streaming, as well as solutions to typical errors.

The Redmi Note 9 (codenamed merlin) features dual-band Wi-Fi (2.4 GHz and 5 GHz), but the default access point only works at 2.4 GHz. We will show you how to force 5 GHz on for greater stability, as well as how to circumvent the restrictions of operators who sometimes block the distribution of mobile Internet. All instructions are relevant for MIUI 12, 13 and 14 firmware (including global and Chinese versions).

1. Preparation of the smartphone before the distribution of the Internet

Before you turn on the hotspot, make sure your Redmi Note 9 is ready for this task. First, check the battery level - the Internet distribution is actively consuming energy, and at a level below 20%, the smartphone can automatically turn off the hotspot. Second, make sure that the device has the latest MIUI updates installed: go to Settings → About Phone → System Update.

Some tariffs (especially unlimited ones) have hidden limits on access points, for example, MTS and Beeline, after 10-15 GB of traffic, can drop to 64 Kbps.

• 📱 Check the tariff conditions on the operator's website or in your personal account.
• 🔄 If the hand is blocked, try restarting your smartphone – sometimes it resets the operator’s restrictions.
• 🛡️ Turn it off. VPN (If you use it, it may conflict with the access point.

⚠️ Note: Redmi Note 9 with firmware MIUI 12.5 and below may trigger a bug where the access point is disabled after 5-10 minutes. MIUI 13+ Or use an alternative method of distribution via Bluetooth.

2. Method 1: Distribution via Wi-Fi (modem mode)

This is the most common and convenient method, and your Redmi Note 9 turns into a full-fledged router that can connect up to 10 devices at a time, to turn on the access point:

1. Open the Settings. → Access Point and modem.
2. Select the Wi-Fi Access Point.
3. Activate the Wi-Fi Access Point slider.
4. Click Access Point Settings to set a network name (SSID) and password.

By default, the network will operate at 2.4 GHz. If you need more speed and less interference (for example, for online games), you can force the switch to 5 GHz:

• 🔧 In the access point settings, select Frequency Range (if no option, see spoiler below).
• 🎯 Install 5GHz and save the changes.
• 🔄 Reboot the access point (turn it off/on again).

Optimal settings for stable operation:

3. Method 2: Distribution via Bluetooth

If Wi-Fi doesn’t work for some reason (e.g., a broken module or a lock on an operator), you can distribute the Internet via Bluetooth, which is less stable and speed-limited (maximum ~3 Mbps), but saves battery life, suitable for connecting laptops, tablets or other smartphones.

Instructions:

1. Turn on Bluetooth on both devices.
2. On Redmi Note 9, go to Settings → Access Point and Modem → Bluetooth modem.
3. Activate the slider and confirm pairing on the second device.
4. On a connected device (e.g. laptop) in Bluetooth settings, select Connect via an access point.

Features of the method:

• 🔋 Battery consumption is lower than Wi-Fi, but speed is limited.
• 🎮 Not suitable for online gaming due to high ping (latency).
• 🔄 When the connection is broken, you will have to reconnect.

⚠️ Note: On some versions MIUI After the update, the option "Bluetooth modem" may disappear. In this case, resetting the network settings will help: → System system → Resetting settings → Reset the network settings.

Method 3: Distribution via USB (Reverse Tethering)

A little-known, but extremely useful way - the distribution of the Internet USB-It provides the most stable speed (up to 100 Mbps) and the lowest battery consumption, as the smartphone charges while running.

To activate USB-modem:

1. Connect the Redmi Note 9 to your computer via the original cable.
2. On your smartphone, select File Transfer (MTP) (important!).
3. Go to Settings. → Access Point and modem → USB-modem and turn on slider.
4. On your computer, check that a new network connection has appeared (in Windows, it is usually called "Ethernet" or "Remote NDIS").

Possible problems and solutions:

• 🖥️ Computer Can't See Internet: Check Drivers (download Mi) PC Suite from the official Xiaomi website).
• 🔌 Smartphone doesn’t charge: Use a fast-charging cable or connect to a mobile phone USB 3.0 (blue port).
• 🛡️ Operator Lock: Try to turn on Flight Mode for 10 seconds, then turn off and reconnect.

💡

If USB-The modem does not work on Windows 10/11, Open Device Manager, find Xiaomi Composite MDB Interface and update the driver manually by specifying the folder with drivers from Mi PC Suite.

5. Optimization of speed and stability of communication

Even if the access point is turned on, the speed can be slow due to interference, operator restrictions or smartphone settings.

For Wi-Fi:

• 📶 Change the channel: Use the WiFi Analyzer app (available on Google Play) to find the least loaded channel.
• 🔄 Turn off traffic savings: In Settings → SIM-maps and mobile networks → Save traffic, disable the option for the current SIM.
• 🚀 Enable Performance Mode: Go to Settings → Battery. → Performance mode and select High Performance.

For mobile Internet:

• 📡 Forced installation 4G: B Settings → SIM-maps and mobile networks → Preferred network type select only 4G (LTE).
• 🔗 Turn it off. IPv6: In the mobile network settings, deactivate IPv6 — It sometimes speeds up the connection.

The Redmi Note 9 with the MediaTek Helio G85 has a hardware limitation: the maximum Wi-Fi speed is 70-80 Mbps, even if the mobile Internet is faster. This is normal and not a malfunction.

💡

If the speed of the distribution drops sharply through 1-2 GB of traffic, most likely, your operator’s “fair use policy” works: the solution is to restart your smartphone or wait for the start of a new day (limits are usually reset at 00:00).

6. Solving typical problems

Even with the right settings, errors can occur. Let's consider the most common and ways to fix them:

If none of these methods worked, try resetting your network settings:

1. Go to Settings → System → Resetting settings.
2. Select Reset Network Settings.
3. Confirm the action and restart the smartphone.

⚠️ Attention: On some firmware MIUI 14 After resetting the network, the option may disappear "USB-In this case, only a full reset to factory settings will help (be sure to back up your phone!).

7. Alternative methods of Internet distribution

If the standard methods do not work, you can use workarounds:

• 🔗 Distribution applications: PdaNet+ ClockworkMod Tether allows you to bypass carrier locks, and note that root access may be required to operate them.
• 🌐 VPN + Access point: Some operators block distribution but do not restrict traffic through the VPN. Install ProtonVPN or Windscribe, connect to VPN, Then turn on the access point.
• 📱 Modem mode through OTG: If you have USB-hub, you can connect Redmi Note 9 to the router via cable and distribute the Internet to other devices via the local network.

For advanced users, there is another way to configure ADB, which allows you to unlock hidden MIUI functions, such as increasing the number of connected devices to 15 or changing the frequency region.

1. Install ADB Tools on your computer.
2. Connect Redmi Note 9 to USB and allow debugging (Settings → About Phone → MIUI version – press 7 times, then Settings → Additional → For Developers → Debugging over USB).
3. Adb shell settings put global settings tether_dun_required 0 It's disabling the check. DUN (Dial-Up Networking, which some operators use to block distributions.
