Xiaomi Redmi 9T is one of the most popular mobile Internet devices thanks to its powerful Snapdragon 662 processor and support for modern communication standards. However, even experienced users sometimes face problems: access point is not turned on, devices are not connected or speed is poor. In this article, we will analyze all the current ways of distributing Internet with Redmi 9T, including hidden MIUI settings, and give specific recommendations for eliminating typical errors.
The model features Wi-Fi 5 (802.11ac) and Bluetooth 5.0 support, which allows it to be used as a full-fledged router for laptops, tablets and even smart TVs. But to harness the full potential, it is important to properly configure network settings. We tested all methods on MIUI 12.5-14 firmware and identified the optimal configurations for stable operation.
1. Method. β1: Wi-Fi Access Point (Modem mode)
The most versatile and quickest method is to convert your smartphone into a Wi-Fi router. On the Redmi 9T, this feature works steadily, but there are nuances with the choice of channel and type of security.
Open Settings β Access Point and modem β Mobile hotspot. Here you can access key settings:
- π Name of the network (SSID): Use a unique Latin name (for example, Redmi9T_Hotspot). Avoid Cyrillic and special characters β this can cause connection problems on some devices.
- π Type of security: Select WPA2-PSK (Optimal balance of safety and compatibility). WPA3 It is supported, but may not work with older gadgets.
- πΆ Frequency range: On Redmi 9T 2.4 GHz (best compatibility) and 5 GHz (high speed but shorter range) are available. For urban conditions, we recommend 5 GHz with 36β48 channel (less busy).
- π Auto-Disable: Disable this option if you plan to give a long hand. By default, the smartphone turns off the access point after 5 minutes without active connections.
After setting up, click Enable Access Point. Connect other devices by entering a password. On Redmi 9T, you can connect up to 10 devices at a time, but for stable operation, we recommend limiting 5-6.
Make sure that the mobile internet is turned on
Check balance (at a tariff with limited traffic)
Choose the optimal range (2.4 or 5 GHz)
Set a strong password (minimum 8 characters)

2. Method. β2: USB-modem (cable connection)
If you need to give the Internet to a PC or laptop without Wi-Fi, use it. USB-This method provides the most stable speed and minimum power consumption (the smartphone will charge while running:
- Connect Redmi 9T to your computer with the original USB Type-C cable.
- In the smartphone settings go to the Access Point and modem β USB-modem and activate the function.
- On PC, check the connection: a new Remote NDIS device should appear in Network Connections.
Advantages of the method:
- β‘ Speed up to 300 Mbps (limited only by operator tariff).
- π No battery consumption β the smartphone is charged while working.
- π‘οΈ More secure than Wi-Fi (no risk of traffic interception).
π‘
If Windows does not recognize USB-modem, install the Mi driver USB Driver from the official Xiaomi website.
β οΈ Attention: When in use USB-modem on Redmi 9T You can block access to the internal memory of the smartphone. To return access to files, disable USB-modem.
3. Method. β3: Internet distribution over Bluetooth
A less popular but useful method in some scenarios is a Bluetooth modem, which is suitable for connecting devices without Wi-Fi (such as some smartwatches or older tablets), speeds are limited to ~3 Mbps, but battery consumption is minimal.
Algorithm of action:
- Turn on Bluetooth on both devices.
- On Redmi 9T, go to Settings β Access Point and Modem β Bluetooth modem.
- Connect the device to your smartphone via Bluetooth (enter the pairing code if required).
- Activate the Bluetooth modem function.
Limitations of the method:
- π’ Low speed (suitable only for instant messengers and light surfing).
- π Maximum 1 connected device.
- π± Not all apps support Bluetooth (for example, YouTube can block video).

4. Optimization of connection speed and stability
Even with the right setup, the speed of the handout can fall due to external factors, and we tested several optimization methods on the Redmi 9T and found the most effective ones:
| Problem. | Reason. | Decision |
|---|---|---|
| Low speed Wi-Fi | Overloaded channel 2.4 GHz | Switch to 5GHz or select a channel manually (e.g. 149) |
| Frequent connection breaks | Energy savings in MIUI | Turn off the adaptive battery in Settings β Battery |
| Devices are not connected. | Incompatibility of type of safety | Change WPA3 to WPA2-PSK |
| USB-The modem is not working. | There are no drivers. | Install Mi USB Driver or use the original cable |
For maximum productivity:
- πΆ Use flight mode with Wi-Fi only enabled and mobile data transmission (this reduces interference from other radio modules).
- π Connect your smartphone to charging β at a battery level below 20% MIUI Automatically limit the speed of distribution.
- π Reboot your smartphone before a long hand (this resets the cache of network settings).

5. Typical errors and their solutions
Even with the right setup, Redmi 9T users are faced with specific errors, and we have collected the most common and ways to fix them:
Error 1: βCannot turn on the access pointβ (message appears when activated)
- πΉ Check if mobile data is enabled (sometimes) MIUI Blocks distribution when the Internet is disconnected).
- πΉ Make sure you donβt have 0 bytes of traffic (some operators block the distribution at zero balance).
- πΉ Reboot the smartphone β it resets the network settings of the kernel.
Mistake 2: Devices are connected, but the internet is not working
- πΉ Check it out. APN-settings of your operator (settings) β SIM-maps and mobile networks β Access points (APN)).
- πΉ Turn it off. VPN or Proxy if they are active.
- πΉ Turn on the mode. LTE in network settings (sometimes) 3G/2G jeopardise).
β οΈ Attention: On firmware MIUI 13+ Background Limitation is available to save traffic, and if it's enabled, some applications on connected devices may not work. β SIM-maps and mobile networks β Background restriction.
6. Hidden MIUI features for advanced users
Redmi 9T has hidden settings that allow you to fine-tune your Internet distribution.
- Turn on Developer Mode: Go to Settings β About Phone and click on MIUI Version 7 times.
- Back to Settings β Additionally. β For developers.
- Find the option Wi-Fi Configuration and select Region β set up the US or Europe to unlock additional 5GHz channels.
Other useful options:
- π§ Debugging by USB β It is necessary to diagnose problems with USB-modem.
- π‘ Always turn on Wi-Fi search β speeds up device reconnection.
- π Channel aggregation β improves speed by 5GHz (enable if supported by your router).
π‘
Changing the Wi-Fi region in a developerβs settings can increase the number of available 5GHz channels from 4GHz to 14, which is especially useful in multi-family homes with more networks.
7. Alternative distribution methods (for experienced users)
If the standard methods do not work, you can use workarounds:
Method 1: Distribution applications (e.g., NetShare or PdaNet+)
These utilities bypass carrier restrictions on distribution (relevant to modem-locked tariffs), and note that they require root rights or ADB activation to work:
adb shell settings put global tether_dun_required 0Method 2: Distribution through ADB Reverse (for developers)
Allows you to redirect internet traffic with Redmi 9T PC-free USB-modems, commands:
adb tcpip 5555
adb connect [IP- smartphone address]:5555
adb reverse tcp:8080 tcp:8080β οΈ Note: Using alternative methods may violate the terms of your plan. Some operators (for example, MTS or Beeline) block such connections and impose penalties.
