Getting the Internet with Xiaomi Redmi Note 8 on PC via USB-cable

In situations where the stationary router has failed, and the Wi-Fi signal in the room is absent or extremely unstable, mobile Internet comes to the rescue. For owners of Xiaomi Redmi Note 8 smartphones, the issue of stable and fast data transfer to other devices remains relevant. Use of the USB-cable for this purpose is the most reliable solution, as it provides not only high connection speeds, but also eliminates battery loss, which is inevitable when working through a Wi-Fi access point.

This method is especially useful for Redmi Note 8 owners whose motherboards or Wi-Fi modules may not support a 5GHz handout or when you want to minimize ping for online gaming on your computer. Unlike wireless, wired USB connectivity is virtually free of external interference and provides a stable communication channel, which turns your smartphone into a full-fledged external modem with high bandwidth.

In this detailed guide, we’ll take you through all the steps of setup, from hardware preparation to solving specific driver problems in Windows, how to activate hidden developer functions when standard methods don’t work, and how to optimize data transfer speeds. It’s important to understand that the function works correctly not only on the phone’s settings, but also on the quality of the cable used.

Before you start setting up, make sure that your Xiaomi device has mobile data enabled and has an active balance or traffic pack. USB-A cable, preferably original or certified, capable of transmitting data rather than just charging the battery. Cheap "charging-only" cables often lack internal contacts to transmit information, making setting up impossible.

Advantages USB-modem before Wi-Fi access point

Using the Redmi Note 8 smartphone as a USB-The modem has a number of advantages over the standard Wi-Fi hotspot function. First, it is energy efficiency. When using the Wi-Fi radio module of the phone consumes a significant amount of energy, causing the housing to heat up and discharge quickly. A wired connection allows you to simultaneously transfer data and charge the device from a computer or power bank, which is critical for long sessions of work.

Second, data security: wireless signals can be intercepted by attackers using weak encryption protocols or simple passwords. USB-The connection is a physically isolated channel that only connected devices can access, making it ideal for handling sensitive information or banking from a computer that does not have antivirus protection.

Third, connectivity stability and speed. Wi-Fi signals are subject to wall attenuation and interference from neighboring networks, microwave ovens and Bluetooth devices. Cable data transmission provides direct contact, which reduces latency (ping) and increases overall channel capacity. For the Redmi Note 8, this means the ability to unleash the full potential of 4G/LTE networks.

⚠️ Attention: When in use USB-In the modem, operators can see that the traffic is not from a smartphone, but from a computer. Some plans limit the distribution of Internet services or require a separate payment for this service.

It is also worth noting the lower load on the smartphone processor. Wi-Fi signal processing requires constant calculations to encode and decode radio waves. With wired connection, this load is minimal, which reduces the heat of the device. Xiaomi Redmi Note 8, equipped with a Snapdragon 665 processor, will work in a more gentle mode, which will positively affect its durability.

Equipment preparation and cable inspection

The success of the operation depends on the quality of the physical connection. Many users have a problem when the phone is charging, but the computer does not see the device. Most often the reason lies in the cable itself. To transfer data from the Redmi Note 8, you need a Micro-USB cable, because this is the connector used in this model. USB Type-C cables are not suitable here without adapters, which can also cause interference.

Visually inspect the connectors for oxidation, dust or mechanical damage. Dirt in the port of the phone is a common cause of poor contact. Carefully clean the connector with a dry toothbrush or a wooden toothpick. Do not use metal objects to avoid closing contacts. If the cable has visible cavities or bends, it is better to replace it, since the veins responsible for data transmission may have been damaged inside.

Check it out. USB-It is recommended to connect the cable directly to the ports on the motherboard (back of the system unit), rather than to the front panel or USB-Hub. The ports on the front may not be giving enough voltage or have poor contact. USB 3.0 (usually blue), they provide better data transfer speeds compared to the previous USB 2.0.

• 🔌 Use the original cable from the Xiaomi Redmi Note 8 kit to guarantee compatibility.
• 🧹 Clean the Micro-USB port of dust with compressed air or dry brush before connecting.
• 💻 Connect the cable to the ports USB 3.0 on the back of the PC for maximum speed.
• 🚫 Avoid using cheap "charging only" cables without shielding.

If you can, test the cable with another device, like connecting your phone to another PC or trying to move files. If the files are transferred, then the cable is good and the settings are not good. If you don't, replacing the cable is the first step to solving the problem. Don't neglect the quality of the accessories, because a bad cable can damage the phone's power controller.

Setting up USB-modem MIUI 11 and newer

The MIUI shell interface on the Redmi Note 8 has its own menu features. The modem activation process is simple enough, but requires care. First make sure that the mobile Internet is on. Then connect the phone with a cable to the computer. Android can request permission to access data if you connect to this PC for the first time - click "Allow" or "Trust".

Next, go to the settings menu. → Connection and sharing. In some versions of firmware, this item may be simply called Connection and Sharing, or it may be in the "More" section. This is where all the data tools are located. Find the switch. USB-If the cable is connected correctly and the computer recognizes the device, this switch will become active (not grey).

Activate the slider. The system can issue a warning that Wi-Fi will be turned off, which is normal behavior as the phone goes into wired distribution mode. The phone will display a USB icon or a symbol indicating an active connection on the status bar on the phone screen, the drivers should be installed on the computer at this time, and a new adapter will appear on the network connection list.

⚠️ Attention: If, after activation, USB-If you don't have an Internet modem on your computer, try to turn off and reconnect the cable without turning off the slider in the settings. Sometimes Windows requires re-initialization of the device.

It is important to note that in the USB-The modem on Xiaomi can be limited to the number of devices connected simultaneously (usually one). Also, the phone screen can go out to save energy, but the connection must be maintained. If the screen goes out and the internet goes down, check your power saving settings and make sure the Settings app or system processes are not limited in the background.

Installation of drivers and problem solving in Windows

Windows 10/11 usually automatically finds and installs the drivers for the Redmi Note 8. However, if you see an unknown device with a yellow exclamation mark or a device called "RNDIS" in the Device Manager, you will need to install manually, which often happens on older versions of Windows or when using non-original cables.

For manual installation, go to Device Manager. Find your device (may be called Android, Xiaomi, or Unknown Device). Right-click and select Update Driver.

Optimizing speed and eliminating common errors

Even with the right connection, internet speeds may be lower than expected.Redmi Note 8 is worth checking settings APN (Access points. Go to Settings. → SIM-maps and mobile networks → Access points (APN). Make sure your operator's access point is selected with the right settings. APN to factory (Reset menu button) helps restore top speed.

Also, the speed is affected by the network signal. If you're in a sensitive reception zone, the phone will waste resources on maintaining communication, and the speed will drop. Try switching network mode in the settings: Choose Preferably 4G over 5G or 3G if the 4G signal is more stable. In some cases, manual selection of the carrier gives a better result than automatic.

Typical errors include blocking a new network connection with antivirus. Check the Windows firewall and make sure the network is defined as "Private" rather than "Public" to allow data sharing. Also check if the "Traffic Saving" mode on Windows is enabled, which may restrict background data transfers.

• 🚀 Reset the access point settings (APN) Updating operator network parameters.
• 📶 Select the network with the best signal manually (LTE/4G) sim card settings.
• 🛑 Turn it off. VPN Proxy servers on the phone and PC at the time of diagnosis.
• 🔄 Restart both devices if the connection speed has dropped to zero.

If the internet is working but pages load slowly, check the background on the phone. MIUI is known for its aggressive optimization, but some apps can consume traffic. Close all unnecessary apps and leave only the minimum you need. Also make sure that the phone does not run system or application updates in the background.
