How to give away the Internet with Xiaomi Redmi 9: a complete guide with the secrets of optimization

Xiaomi Redmi 9 is one of the most popular mobile Internet devices for the sake of price and functionality balance. However, many users face problems: the access point is not turned on, the devices are not connected, the speed is not good. This article will not only tell you how to distribute Wi-Fi from the phone, but also reveal the nuances that the manufacturer does not keep silent, from hidden settings MIUI to ways to circumvent the restrictions of operators.

We tested all the methods on Redmi 9 with the latest versions. MIUI (including MIUI 14 based on Android 12) and revealed the key points: why handouts through USB-The cable is more stable than Wi-Fi, with a weak network signal, how to set up the broadcast channel to minimize interference, and why some laptops "can't see" the access point from Xiaomi?

Phone Preparation: What to Check Before Setting Up an Access Point

Before you turn on modem modem, make sure your Redmi 9 is ready to give the Internet. Skipping these steps often leads to errors like “failed to turn on the access point” or lack of network on the connected devices.

First, check the balance and the tariff. Many operators (especially Tele2 and Iota) block the distribution of Internet at cheap rates or limit its speed to 64 Kbps. USSD-request:

• 📱 MTS: *111*0887# — check-up»
• 📱 Beeline: *110*180# — Status of the service "Internet for devices»
• 📱 MegaFon: *105*00# — tariff

If the distribution is blocked, connect the appropriate option (cost - from 50 rubles / day).

Second, update your firmware. Older versions of MIUI (below MIUI 12.5) have a bug that causes the access point to shut down after 5 minutes. To check the software's relevance, go to Settings → About Phone → System Update. If an update is available, install it by pre-connecting the phone to charge.

⚠️ Note: If you use custom firmware (such as LineageOS or Pixel Experience), the Wi-Fi distribution may not work smoothly due to the lack of drivers for the Wi-Fi Direct module. MIUI.

Ways to distribute the Internet with Redmi 9: comparison and selection of the optimal

Xiaomi Redmi 9 supports three ways to distribute the Internet: via Wi-Fi (access point), Bluetooth and USB-Each option has pros and cons, which depend on your tasks:

For most users, Wi-Fi at 5GHz is optimal, providing high speeds and less congestion. However, if you need to connect a device without 5GHz support (for example, an old printer), choose 2.4GHz. USB tethering is suitable for working behind a laptop when stability and battery saving are important.

Step-by-step: how to turn on the access point on Redmi 9

Now, let's get to the practice, you can turn on the Wi-Fi on Redmi 9 in 30 seconds, if you know the right way to do it.

1. Open Settings (the gear icon on the main screen).
2. Go to the Network and Internet → Modem and access point.
3. Slip on the Wi-Fi Access Point.
4. Activate the slider at the top of the screen.
5. Set up network settings: 🔑 Name of the network (SSID): Think of a unique name (for example, Redmi9_Hotspot). Avoid Cyrillic – some devices don’t support it. 🔒 Password: minimum 8 symbols, with numbers and letters (example: Xiaomi2026!). 📡 Range: Choose 5 GHz for speed or 2.4 GHz for compatibility. 🔄 Auto-Disable: Turn off this option if you plan to use it for a long time.

Save.

If the access point does not appear in the network list on other devices after activation, check:

• 🔌 Is the mobile internet connected (Icon) 4G/3G status-line).
• 📵 Is the “In the Airplane” mode enabled (Settings) → Connections → Flight mode).
• 🔄 Did the automatic shutdown work due to inactivity (check the battery settings).

Hidden MIUI settings: how to increase speed and stability of distribution

By default, Xiaomi Redmi 9 limits Wi-Fi speeds to 30-40 Mbps, even if your tariff supports large values.This is done to save battery power, but you can bypass the restriction through the engineering menu.

First, activate the developer mode:

1. Go to Settings. → The phone.
2. Tap 7 times on the MIUI version until the notification “You became a developer” appears.
3. Back to Settings → Additionally. → For developers.
4. Enable USB Debugging and OEM Unlocking.

Now open the engineering menu:

1. Enter the code in the phone app: ##4636##.
2. Select Wi-Fi Information.
3. Scroll down to the Wi-Fi Hotspot Settings block.
4. Change the parameters: 📶 Wi-Fi Frequency Band: Install 5 GHz (if your devices support your device). 🔄 Hotspot Auto Shutdown: Turn Off (Disable). 🚀 Max Clients: Increase to 10 (default: 5).

⚠️ Warning: Changing the settings in the engineering menu can lead to unstable Wi-Fi. If the access point stops working after settings, reset the network settings in Settings → System system → Resetting settings → Resetting Wi-Fi, Mobile Network and Bluetooth.

💡

If you don't get any more speed after you change your settings, try changing your Wi-Fi channel manually. In the engineering menu, select the Wi-Fi Channel and set it to 36 or 149, which are the least crowded in urban areas.

The solution to the problems: why Wi-Fi distribution on Redmi 9 does not work

Even after you set it up properly, Redmi 9 users are faced with typical problems, and we've put together solutions for the most common cases.

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

Causes and means of elimination:

• 🔐 Wrong password: reset the access point settings and set a new password without special characters.
• 📵 Conflict IP-Addresses: in the settings of the access point (Settings) → Modem mode → Wi-Fi hotspot → Additional) change the Range IP s 192.168.43.x on 192.168.150.x.
• 🔄 Interference from other networks: Use the Wi-Fi Analyzer app (available on Google Play) to find a free channel.

2.The distribution is off in 5-10 minutes

This is standard MIUI behavior for saving charge, to turn off auto-switching:

• Go to Settings → Battery and Performance → Battery Optimization.
• Find the modem mode in the list and select No restrictions.
• Turn off the option Automatic disable access point in the modem settings.

3. Low dispensing speed (less than 1 Mbit/s)

The culprits:

• 📡 Weak signal of mobile network: check the signal level in the engineering menu (##4636## → Network information). If RSRP below -110 dBm, move closer to the window or use a repeater.
• 📉 Operator restriction: some tariffs (e.g. Smart from MTS) artificially reduce the speed of distribution.
• 🔋 Energy saving: Turn off traffic saving mode in Settings → SIM-maps and mobile networks → Saving traffic.

How to Save Traffic and Battery When Distributing Wi-Fi

Internet is one of the most energy-consuming functions of a smartphone, and when you use the Redmi 9, it discharges by 15-20% per hour, and traffic is consumed 2-3 times faster than when you connect directly.

Savings in battery charge

• 🔋 Use USB-tethering: when connected via cable, the phone not only does not discharge, but also charges (if the laptop gives enough power).
• 🌙 Reduce the brightness of the screen to a minimum and turn on a dark theme – this will reduce the load on the processor.
• ❄️ Turn off background processes: in Settings → Annexes → Auto-Run Ban Auto-Run Unnecessary Programs.

Traffic control

• 📊 Set the limit: in Settings → SIM-maps and mobile networks → Set a monthly limit and enable notifications when exceeding.
• 🚫 Block “glutty” sites: Use the NetGuard app (free on Google Play) to restrict access to social networks and video hosting for connected devices.
• 🔄 Enable data compression: in Google Chrome, activate the option “Saving traffic” (Settings) → Saving traffic).

If you distribute the Internet to a laptop, set a background traffic limit in it:

• In Windows 10/11: Settings → Network and Internet → Wi-Fi → Managing Known Networks → [Your Network] → Setting as a Limit Connection.
• In macOS: System settings → Network → Additional → Limit background traffic.

💡

The most effective way to save both traffic and charge is to use USB tethering, while keeping the speed high and the phone charging from the laptop.

Alternative methods of distributing the Internet without a built-in access point

If the standard handout function doesn't work (for example, because of a firmware failure), you can use workarounds, which require additional actions, but save in critical situations.

1. Distribution via Bluetooth (for devices without Wi-Fi)

Suitable for connecting old printers, fitness bracelets or car radios:

1. Turn on Bluetooth on both devices.
2. On Redmi 9, go to Settings → Modem Modem → Bluetooth modem.
3. Select the device from the list and confirm the pairing.

The disadvantage of the method is low speed (~1 Mbit / s) and frequent communication breaks.

2. Distribution via USB (if the Wi-Fi module is broken)

If your phone’s Wi-Fi adapter is faulty but the USB port is working, use USB-tethering:

1. Connect your phone to your PC/laptop with a cable (preferably original).
2. B Settings → Modem mode, turn on. USB-modem.
3. On your computer, wait for the drivers to install (if Windows requests, select Search Online).

If drivers are not automatically installed, download them manually from the Xiaomi website (section “Drivers for PC”).

3. Distribution through third-party applications

Apps like PdaNet+ or ClockworkMod Tether allow you to bypass carrier restrictions, but require root rights.

• 🛡️ Risks: the operator may block the distribution or impose penalties.
• ⚙️ Setup: After installing the application, turn on Hide Tether Usage mode (hiding the distribution).
