How to distribute the Internet with Xiaomi Redmi 9: a step-by-step guide

Modern smartphones have long since ceased to be just devices for calls, becoming powerful tools for work and entertainment. Xiaomi Redmi 9 model from the Chinese manufacturer has proven to be a reliable device with good autonomy, making it an ideal candidate for the role of a mobile router. In situations where a stationary provider is unavailable or there was a failure in the work of home equipment, the ability to distribute the Internet becomes a critical feature.

The process of organizing a wireless network Hotspot Wi-Fi based on the operating system Android with the shell MIUI intuitively, but has a number of nuances. Users often face restrictions on the number of connected devices or problems with network visibility by other gadgets. In this article, we will discuss in detail all available methods of traffic transmission, including wired options that ensure the stability of the connection.

Redmi 9 owners should consider that active data distribution significantly affects battery power and body temperature. Properly configuring security parameters and frequency range will help minimize the risks of overheating and unauthorized access. Next, you will find comprehensive instructions that will allow you to turn your phone into a full-fledged network control center in minutes.

Setting up a classic Wi-Fi access point

The most common and convenient way to share the internet is to create a wireless hotspot. First, go to the main settings menu of your Redmi 9. Find the section, which is usually labeled as Connections and Sharing or simply Access Point, depending on the version of the MIUI firmware.

After you log in, select "Wi-Fi Access Point." Here you need to activate the power slider. Before connecting other devices, it is crucial to configure security settings. Click on your network name to change your SSID (name) and set a complex password using WPA2 PSK encryption.

⚠️ Note: Do not leave your access point open without a password in public places, as attackers may intercept your data or use traffic for illegal activities.

The same menu also includes the option of “Dual-band access point.” Switching to 5 GHz will provide a higher data rate, but the signal range will be less than that of the 2.4 GHz standard. For most use cases indoors or outdoors, 5 GHz will be the optimal choice if the receiving device supports this range.

Distribution of the Internet through USB-cable

When you want maximum connection stability, or you need to charge your phone while you're working, the best solution is a wired connection. USB Tethering, which allows you to transfer Internet traffic from Xiaomi Redmi 9 to a computer or laptop via cable. USB-Port quality and the quality of the cable.

To activate the function, connect your smartphone to your PC using a serviceable cable. On the phone screen, a request for mode of operation may appear. USB, Select "Charge Only" or "File Transfer" although this is not always critical for the distribution itself. Next, on the phone, go to the access point settings menu and find the switch «USB-modem».

The computer automatically recognizes the new network connection and installs the necessary drivers. Unlike Wi-Fi, wired connections eliminate interference from other wireless devices, which is especially true in apartment buildings with many neighbor networks. Also, when connected via USB, the phone can charge faster than when running in Wi-Fi router mode, since some of the energy is transmitted directly.

⚠️ Attention: When in use USB-Make sure that the computer has the latest drivers for mobile devices, otherwise the system may not see the Internet.

It's worth noting that you can't normally distribute Wi-Fi and USB to different devices from the same phone at the same time, but for a stationary workplace, it's the best option for stable ping and fast download speeds.

Using Bluetooth to Transfer Data

Although this method is considered obsolete due to its low speed, it can be a lifeline in emergency situations when other options are not available.Bluetooth PAN technology allows you to create a network between two devices with minimal power consumption. The speed here rarely exceeds 1-2 Mbps, which is enough for messengers or navigation, but not enough for streaming video.

To set up the connection, first pair Redmi 9 with a receiving device (such as a tablet or laptop) through the standard Bluetooth menu. Make sure both devices have visibility enabled. After successfully pairing on the phone in the access point menu, activate the "Bluetooth modem" option.

On the receiving device, you need to find your phone in the list of available Bluetooth devices, select it and click Connect through -> Access Point. The connection process can take up to 30 seconds. This method is good because it practically does not heat the smartphone case and consumes little power.

Managing Connected Devices and Limits

The MIUI shell provides enhanced capabilities to monitor who is using your Internet. In the hotspot menu, you can always see a list of connected customers. It displays the names of the devices and the amount of traffic they consume, allowing you to quickly identify freeloaders.

To prevent unauthorized access and overspending, you should set a limit. In the access point settings, look for “Traffic Limit” or “Disposable Limit”; you can set a volume of data that will automatically stop being used up, which is especially useful if you have a limited gigabyte packet rate.

Also available is the function “White list”, allowing you to allow connection only predefined devices on their MAC-This is the most reliable way to protect, because even if you know the password, an outsider will not be able to connect to your Xiaomi network.

Solving Connection Problems

Sometimes users are faced with a situation where the access point is turned on, but other devices do not see the network or cannot access it. IP-First, check if the Redmi 9 is running the mobile internet, and without an active connection to the operator's network, the phone will not be able to broadcast the data any further.

Another common reason is bandwidth incompatibility. If you set your 5GHz settings and your old laptop or tablet only supports 2.4GHz, it simply won't detect the network. Try switching to the standard 2.4GHz band in the hotspot settings.

⚠️ Warning: If the phone gets too hot during the handout, remove the protective case and put the device on a hard surface for better heat sink.

In some cases, network resets help. Go to Connections and Sharing, find the reset button, or just turn off and turn on flight mode. Also make sure the phone doesn't have antivirus apps or firewalls that can block incoming connections from other devices.

Optimizing energy consumption and safety

Internet distribution is an energy-intensive process that quickly lands the battery. To extend the time of the Redmi 9 in router mode, reduce the brightness of the screen or turn it off altogether. In the access point settings, be sure to activate the automatic shutdown function if no one is connected to the network for 5-10 minutes.

From a security perspective, never use simple passwords like 12345678. Use a combination of different register letters and numbers. Change your password periodically, especially if you've been giving the Internet to strangers. Also keep an eye out for MIUI updates, as they often contain security patches for network modules.

💡

For maximum charge savings, turn on Invisibility mode in the access point settings – then only those who know the exact network name (SSID) can connect.

Remember that the Wi-Fi module can be constantly running at high frequencies, and if you plan a long session, it’s best to use a flight mode with only Wi-Fi on (if your version of Android allows) or a connected USB to minimize your cellular network search.

💡

The combination of the right frequency selection, strong password, and control over connected devices makes your Redmi 9 a secure and efficient mobile router.
