Xiaomi Redmi 9 can be a full-fledged router if you need to urgently distribute the Internet to a laptop, tablet or other phone. But many users face problems: the access point does not turn on, devices do not connect, or the battery dies in 30 minutes. In this article, step-by-step instructions for all versions of MIUI (12 to 14), ways to save charge when dealing and solve 90% of typical errors.
We tested all methods on Redmi 9 (M2003J15SC, M2004J19C), but the instructions will also work for other devices in the Redmi Note 9/9T/9 Pro series - the differences are only in the location of menu items. If your phone runs on pure Android (without MIUI), use the third method at the end of the article.
1. Preparation of the telephone before distribution of the Internet
Before you turn on the access point, check 4 key parameters – this will save you 80% of connection problems:
- 📶 Mobile Internet: Make sure there is a stable signal on the phone 4G/LTE (Icon in status bar if the letters H are+ or 3G, speed 5–10 lower.
- 🔋 Battery charge: when you distribute Wi-Fi, the phone consumes up to 30% of the charge per hour (tests on Redmi 9 with the switch on) GPS). Charge the battery to at least 40%, otherwise the system may disable the access point.
- 📱 Updates MIUI: In older versions of firmware (below 12.0.8), there is a connection break bug. → The phone. → Updating the system.
- 🔒 Default Password: If you have never set up an access point, the password may be standard – 12345678 or a combination of IMEI phone (recognize him: *#06#).
Pay special attention to the mobile operator. Some tariffs (e.g., SberMobile or Tinkoff Mobile) block the default Internet distribution. USSD-request:
*100#Or call the operator to "allow tetering" (the official term), which is usually activated by default on MTS, Beeline and Tele2.
2. Method 1: Distribution via the "Modem Mode" menu (recommended)
This is the most reliable method for MIUI 12-14.
- Open Settings → Connections and Sharing → Modem Modem.
- Slip on the item "Wi-Fi access point".
- Activate the slider in the top corner.
- Click on “Access Point Settings” to change: 🔐 Name of the network (SSID) — for example, Redmi9_Hotspot. 🔑 Password minimum 8 Symbols (it is better to mix letters and numbers). 📡 Range - select. 2.4 GHz for maximum compatibility (5 GHz is faster, but not all devices support it).
Save the changes and re-enable the access point.
If after turning on the error "Can not turn on the access point", reset the network settings:
Settings → Connections and Sharing → Resetting Wi-Fi, Mobile Network and BluetoothAccess Point is enabled (Icon burns) 📶 notification-bar)
Password entered without errors (registration is important!)
VPN is disabled on the connected device
Distance between devices not more than 10 meters-->
Method 2: Quick activation through the notification panel
If you need to distribute the Internet urgently, use quick access:
- Swipe your finger down from the top of the screen to open the notification bar.
- Find the icon “Access Point” (three wave icon) 📶). If it is not, tap on a pencil ("Edit") and add to the active elements.
- Hold the icon for 2 seconds and the Modem Mode will open.
- Click on “Wi-Fi Access Point” and activate the slider.
⚠️ Attention: this method uses default settings (network name is phone model, password is 12345678). If you haven't changed them, even third-party devices within a radius of 50 meters can connect. Always adjust the password manually!
💡
To save charge, reduce the brightness of the screen to 30% and turn off the auto-update of applications (Settings → Apps → Autoboot).
Method 3: Distribution via USB or Bluetooth (alternatives)
If Wi-Fi is not working or you need to connect a device without wireless support (such as an old laptop), use:
| Method | Speed. | Battery consumption | When to use |
|---|---|---|---|
| USB-tetering | Up to 40 Mbps | Low (phone charging) | For laptops without Wi-Fi or with a weak signal |
| Bluetooth tetering | Up to 3 Mbps | Medium. | For devices without Wi-Fi/USB (e.g. smartwatches) |
| Wi-Fi Direct | Up to 10 Mbps | High-pitched | To transfer files between Xiaomi devices |
To turn on USB-tetering:
- Connect your phone to your computer via cable (preferably the original one from Xiaomi).
- In the modem modem menu activate «USB-modem».
- A new Remote NDIS device will appear on your computer in Network Connections.
If the body temperature is above 42°C, the Internet speed drops by 30-50% (tests using Speedtest). If the phone gets hot, take a break for 10 minutes.

6. Solving Internet Distribution Problems
If your devices are not connected or the internet is not working, check:
| Problem. | Reason. | Decision |
|---|---|---|
| Devices do not see the access point | Wrong Wi-Fi range | In the point settings, select 2.4 GHz instead of 5 GHz |
| The connection is there, but the internet is not working. | Blocking by the operator | Call the operator and request tethering activation |
| Access point shuts down after 5 minutes | Battery savings | Turn off the adaptive battery in the power settings |
| Low speed (less than 1 Mbps) | Weak 3G signal | Switch to the switch. 4G In Settings → SIM-maps and mobile networks → Preferred type of network |
If nothing helps, reset your network settings:
Settings → Connections and Sharing → Resetting Wi-Fi, Mobile Network and Bluetooth⚠️ Note: after reset, you will have to re-enter passwords from all saved Wi-Fi networks and associated Bluetooth devices (earphones, fitness bracelets, etc.).
