How to turn it on USB-Modem Xiaomi Redmi Note: full guide

Using a smartphone as an Internet access point for a laptop or desktop computer is a scenario that has become commonplace in the absence of stable Wi-Fi. Owners of Xiaomi devices often face the need to quickly distribute mobile traffic, and a wired connection here is the most reliable option, USB-The modem provides a stable data transfer speed and simultaneously charges the gadget, which is critical for long-term work.

Many users are unaware that activating this feature requires several preconditions to be met, without which the system is not fully functional. MIUI It's not going to allow you to use your phone as a network adapter, and often it's not software failures that are the problem, but it's just a simple lack of access rights or a mischosen mode. USB-Understanding these nuances will save you time and nerves when trying to connect via mobile Internet.

In this article, we will take a closer look at the setup process, from checking your SIM card to fine-tuning your network settings. You will learn how to bypass typical connection errors and why your computer may not see your Redmi Note even if the cable is working.

Preparation of the device and checking the SIM card

The first and most obvious step is to physically check the hardware readiness. Make sure your Redmi Note has a SIM card installed by an operator that provides 4G or at least 3G coverage at your location. Without an active connection to the base station, further setting up the modem mode makes no sense. Also check your account balance, as some operators block the distribution of traffic on unlimited Internet rates unless a special option is connected.

It is important to understand the difference between normal mobile internet use and distribution. TTL-If you plan to use your phone as your primary PC Internet source, make sure your data plan allows it, otherwise the speed may be artificially limited by the provider to the minimum, regardless of the signal quality.

⚠️ Attention: Some operators automatically detect the connection of the computer and may block access or charge an additional fee. check the terms of your plan before activating the handout to avoid unpleasant surprises with the bill.

Don't forget the state of your own. USB-Cheap cables, bundled with budget electronics or bought separately, often only support charging and have no internal contacts to transmit data. USB-If the computer makes the device's connection sound but doesn't define it as a network adapter, try replacing the cord with an original or certified analogue.

Activation of the developer mode and debugging via USB

In the Android operating system that runs the MIUI shell, port management functions are often hidden from the average user. To access them, you need to activate a hidden menu. Go to Settings → About your phone and find the MIUI version string. Click on it quickly 7-10 times in a row until a pop-up notice that you have become a developer appears.

Once you activate the hidden menu, go back to the main settings menu and select Additional (or Advanced Settings) where you will find a new Developer section. In the options list, find and activate the USB Debugging Switch, which allows the computer to access the phone’s system functions more deeply, which is necessary to emulate the network interface.

When you first connect to a PC with debugging enabled, the smartphone screen will request permission to debug from that computer. Be sure to click OK or Allow, pre-check "Always Allow from this computer." Without confirmation of this action, the phone will only charge, ignoring the commands to transfer data.

It’s worth noting that turning on the developer mode can affect the performance of some banking or anti-cheat apps, as they see debugging as a sign of a potential security threat. Once you set up the modem, if you no longer plan to use the developer tools, this feature can be disabled to improve system security.

Setting up the access point and USB-modem

The main process of activation is in the network settings menu. Go to Settings → Wi-Fi Access Point. In some versions of MIUI, this item may be simply called Access Point or located in the Connectivity and Sharing section, and this is where all the tools for distributing the Internet are concentrated.

In the menu you will see the option. USB-Note that this item will be inactive (grey) if the phone is not connected by cable to the computer or if debugging is done by the computer. USB Once you connect the devices with a high-quality wire, the switch becomes active. Turn it on, and in a few seconds the system should recognize the new network connection.

After enabling the function on the smartphone screen, a notification may appear that it is running. USB-modem: A computer in the tray (near the clock) should have a new network connection icon, usually indicated by a monitor icon with a cable. Windows will automatically install the necessary drivers if it has access to the Internet through another channel, or uses standard drivers. RNDIS.

Solving driver problems in Windows

The most common problem when connecting Xiaomi to a computer running Windows 10 or 11 is the lack of correct drivers. The system can identify the device as an “Unknown device” or charger, in which case you need to manually update the network adapter driver through Device Manager.

Open Device Manager, find a device with a yellow exclamation mark or device in the Network Adapters section called RNDIS or Remote NDIS. Right-click, select Update Driver, then Search for drivers on this computer, and Select a driver from the list of available. From the manufacturer list, select Microsoft, and from the model list, Microsoft USB RNDIS Adapter or Android USB Ethernet/RNDIS.

If the automatic installation doesn't work, you can try installing the official Mi PC Suite utility, although it's often unstable on newer versions of Windows. A more reliable way is to use Google USB Driver universal drivers via the Android SDK, but this requires more in-depth knowledge. In 95% of cases, manual selection of the RNDIS driver solves the problem.

Configure APN and mobile Internet settings

Even if you successfully connect a device, the Internet may not work, and this is often due to the wrong settings of the access point. APN. The carriers require these parameters to be specified precisely to log in to the network. → SIM-maps and mobile networks → Choose yours. SIM-map → Access points (APN).

If the internet is not working, click the Reset button (usually three dots in the corner or the button at the bottom) to restore factory profile settings. Some operators, especially virtual ones (MVNOs), may need to manually create a new access point with an exact input of the name and address of the APN, which can be found on the operator's website.

Special attention should be paid to the type of APN protocol. In modern networks, IPv4/IPv6 mode works best. If you have problems accessing certain resources, try changing this setting. Also make sure that there is no proxy server and port installed in the access point profile, unless your operator explicitly requires it.

⚠️ Attention: When manually adjusted APN Check the letter register carefully. Some operators require a match, such as the Internet instead of the Internet, although this is rare.

Additional settings and speed optimization

To ensure stable employment USB-modem on Xiaomi Redmi Note is recommended to disable energy savings for system processes responsible for the network. → Battery → Settings and make sure that the power saving mode does not limit the background activity of network services. MIUI may break the connection when the screen is blocked.

It is also worth checking whether 2G/3G Only is activated in your preferred network type settings. For maximum speed, choose LTE or 5G if your tariff and coverage allow. Using outdated communication standards will significantly reduce download speeds and increase ping, which is critical for video calls or online gaming.

💡

If the connection speed is unstable, try to switch the phone to flight mode for 10 seconds and then turn it off.This will force the device to re-register on the network and often helps find a looser base station.

Remember that when you're actively spreading the Internet, your smartphone can get a lot of heat. This is the normal physical reaction of the processor and modem to high load. However, if the temperature becomes critical, the system can automatically turn off the modem to protect the hardware. Use your phone on a hard surface or remove the case for better heat sink during long sessions.
