How to give away the Internet with Xiaomi Redmi Note 9 Pro: a complete guide with settings

Introduction: why give the Internet from a smartphone

Modern Xiaomi smartphones have long ceased to be just means of communication — they have become full-fledged mobile routers. Redmi Note 9 Pro with its powerful Snapdragon 720G processor and Wi-Fi 5 support is able to distribute the Internet to 10+ devices simultaneously, without losing speed. But why is it necessary?

There are a lot of situations, from the lack of home Wi-Fi on a trip to the need to connect a laptop to the mobile Internet on a business trip, and sometimes it is easier to distribute the Internet from your phone than to set up complex routers in a hotel, USB-modem and Bluetooth tetering to avoid typical problems like slow speeds or sudden breaks.

In this article, you will find unique data on optimizing the Internet distribution for the Redmi Note 9 Pro, including hidden MIUI settings that the manufacturer does not advertise, and you will learn not only how to turn on the access point, but also how to increase speed by 30-40% by adjusting network parameters.

Method 1: Distribute Wi-Fi via an access point (hot spot)

The most popular method is to convert the Redmi Note 9 Pro into a full-fledged Wi-Fi router, with advantages such as high speeds (up to 150 Mbps at 5 GHz), multi-device support, and minimal delays, but there are pitfalls: fast battery life and possible limitations from a mobile operator.

To activate the access point:

1. Open the Settings. → Access Point and modem.
2. Select the Mobile Access Point.
3. Switch the slider to the "On" position.
4. Click Access Point Settings to set a network name (SSID) and password.

The best options for the Redmi Note 9 Pro:

• 🔄 Range: 5 GHz (if connected devices are supported) – less interference and faster speed.
• 🔒 Type of security: WPA2-PSK (The most balanced in terms of safety and compatibility).
• 📶 Channel: Auto or manually select the least loaded (use the WiFi Analyzer app).

Mobile Internet is enabled and stable|Battery charged at least 50 times%|Connected devices are disabled VPN|The password of the access point contains at least 8 characters.-->

Important point: if the speed of the handout suddenly fell, check the settings → SIM-maps and mobile networks → Network type: The best option for Redmi Note 9 Pro — 4G (LTE). Forced choice 3G may increase the coverage area, but reduce the speed of 2-3 once.

💡

If the connected devices are constantly falling off, try changing the Power Saving Mode to Maximum Performance in the AP settings, which will increase the phone's heating, but stabilize the connection.

Method 2: Distribution of the Internet over USB (USB-modem)

A lesser known but more stable way is to use the Redmi Note 9 Pro as a sleek, sleek, and sleek way to do it. USB-Suitable for laptops and PCs that require constant connection without the risk of a break, speed is limited only by the possibilities of your tariff, and the battery of the phone does not suffer (it even recharges from the power of the battery). USB).

Instructions for setting:

1. Connect your phone to your computer through the original USB-cable (cheap cables may not support data transmission).
2. On your phone, select File Transfer (MTP) mode in the connection notification.
3. Go to Settings. → Access Point and modem → USB-modem and activate the function.
4. On your computer, wait for the driver to install (Windows usually does this automatically).

Challenges and solutions:

Wi-Fi access point|USB-modem|Bluetooth|Not using.-->

For advanced users: if your operator is blocking USB-tetering (for example, MegaFon or Beeline on some tariffs), you can bypass the restriction through ADB. Connect your phone to your PC, activate Debugging USB Developer Settings and execute the command:

adb shell settings put global tether_dun_required 0

This command drops the restriction flag, but may require a reboot.

Method 3: Distributing the Internet via Bluetooth

The most cost-effective battery charge, but also the slowest, is Bluetooth tetering, which rarely exceeds 3-5 Mbps, but the power consumption is minimal, and the connection is stable even at a distance of 10 meters, ideal for connecting a tablet or other phone where high speeds are not necessary.

Connection algorithm:

1. Turn on Bluetooth on both devices.
2. Connect the Redmi Note 9 Pro to the target device.
3. In your phone, go to Settings → Access Point and modem → Bluetooth modem.
4. On the connected device, in Bluetooth settings, select Connect to the Network (on Android) or Personal Network Connection (on iOS).

Features of Redmi Note 9 Pro for Bluetooth tetering:

• 🔋 Consumes 3 times less energy than a Wi-Fi hotspot.
• 📱 Supports simultaneous connection of up to 3 devices (unlike many other smartphones with a limit of 1).
• 🔄 Automatically reconnects after signal loss (if devices remain in range).

If the speed is critically low, check the Bluetooth version on the plug-in device. For example, an iPhone with Bluetooth 5.0 may show a more stable connection than an older Android tablet with Bluetooth 4.0.

Optimization of speed and stability of distribution

Even a properly configured access point on the Redmi Note 9 Pro can slow down due to hidden limitations.

1. Change of network regime

By default, the phone uses a balanced mode, but for distribution it is better:

• 📡 Go to Settings. → SIM-maps and mobile networks → Type of network.
• 🔄 Select Only. LTE (if 4G stable 3G/4G (car-balance.

2. MTU setup

Not everyone knows, but in MIUI you can manually set MTU (maximum packet size), which reduces latency. The optimal value for most operators is 1472.

adb shell settings put global tether_dun_mtu 1472

3. Background activity shutdown

Apps like Facebook or TikTok can steal traffic even in the background.

1. Activate Flight Mode for 10 seconds, then turn it off.
2. In Settings → Applications → Permissions, turn off background internet access for unnecessary applications.

💡

The most effective way to increase the speed of the transfer is to use 5 GHz for Wi-Fi and turn off all background updates on the phone, which gives an increase of up to 40% compared to standard settings.

Typical problem solving

Even with the right settings, Redmi Note 9 Pro users are plagued with bugs, and the most common ones are:

1. Access point is turned on, but devices are not connected

⚠️ Warning: If, after activating the access point, devices see the network but cannot connect ("Getting the access point") IP-Addresses, problem with settings DHCP. Go to Settings. → Access point → Setting up the access point and changing the range IP s 192.168.43.x on 192.168.1.x.

2.The Internet is working, but the page is not opened

Frequent problem when connecting to USB-The culprit — DNS operator:

• 🌍 On the computer manually write DNS 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).
• 📱 On the phone in Settings → SIM-map → Access point (APN) Check that it is correct. APN your operator.

3. Fast battery discharge

With an active access point, the Redmi Note 9 Pro can lose up to 1% of its charge per minute.

• 🔋 Connect the phone to charge (even a weak current in the 5V/1A offset).
• ❄️ Reduce screen brightness to 30% and turn off Auto Brightness.
• 📴 Activate Power Saving Mode, but exclude Settings from optimization (otherwise, the access point may be turned off).

4.The operator is blocking the distribution

Some tariffs (for example, "All for 300" from Tele2) restrict tethering.

• 🔄 Restart your phone in Safe Mode (hold the power button) → Safe regime).
• 📡 Enable the access point in safe mode – sometimes restrictions are reset.
• 🛠️ Use applications like PDANet+ (requires root rights).

Hidden MIUI functions for Internet distribution

Xiaomi hides a few useful options that are not visible in the standard interface, and can be activated through the Developer Settings or ADB:

1. Forced use of 4G for tethering

If your phone switches to 3G when you hand it out, do:

adb shell settings put global preferred_network_mode 9

Where 9 is LTE priority.

2. Increase the limit of connected devices

By default, Redmi Note 9 Pro allows you to connect up to 8 devices, but the limit can be removed:

adb shell settings put global tether_entitle_device_num 15

3. Disabling the authentication of tetering

Some operators send special packets to detect tethering, to block them:

adb shell settings put global tether_dun_required 0


adb shell settings put global tether_entitle_check_timeout_ms 0

This is a mechanism in Android that checks whether tetering is allowed under the operator's terms, and disabling this check can bypass locks, but theoretically violates the user agreement of some mobile operators.-->

Warning: changing hidden settings can lead to unstable operation of the communication module. If after experiments, mobile Internet disappears, reset the network settings to Settings → System → Reset settings → Reset mobile network settings.
