How to turn on the modem on Xiaomi Redmi: step-by-step setting

Modern smartphones in the Redmi and Xiaomi series have long ceased to be just devices for calling, becoming powerful tools for organizing mobile Internet anywhere in the world. Gadget owners often wonder how to turn on a modem on Android to use a 4G/LTE SIM card connection to connect to the network on a laptop or tablet. This is especially true on trips where there is no stable Wi-Fi and wired Internet is not available.

The MIUI or the new HyperOS allows you to turn your phone into a full-fledged router in minutes, you can use a wireless connection over Wi-Fi or connect your device with a cable for more stable and faster data transfer. Understanding the intricacies of settings will help you avoid common errors and ensure maximum download speed.

In this guide, we will discuss in detail all the available ways to activate modem modem, from basic interface settings to hidden features for advanced users. USB-cables, settings APN and methods of circumventing the restrictions of mobile operators, which will make your smartphone a universal tool for work.

Basic setting of the Wi-Fi access point

The most common and easiest way to distribute the Internet is to create a wireless hotspot. You need to go to your device's settings menu first. On most Xiaomi and Redmi models, this path looks standard: open Settings, then find the Wi-Fi hotspot section. In some firmware versions, this item may be hidden inside the Connect and Sharing menu.

Once you log in, you'll see a switch that activates modem modem. However, before you start, it's important to set up security settings so that no outsiders connect to your network. Click on your network name or Setting Up an Access Point button to change your name (SSID) and set a strong password. WPA2-Personal encryption standard is recommended, as it provides the optimal balance between speed and data protection.

Pay attention to the frequency range. By default, the system can offer a frequency of 2.4 GHz, which has a longer range but less speed. If your laptop or tablet supports the 5 GHz standard, it is better to switch the access point to this range for maximum performance, this is especially important when watching high-resolution video or online games.

💡

If you distribute the Internet to a laptop that is next to your phone, always choose the 5GHz band – this will significantly reduce ping and increase connection stability.

Remember to monitor the list of connected devices. The access point menu has a Connected Devices section that displays all the gadgets that are using your traffic. If you notice an unknown device, immediately change your password and deny access to unauthorized customers.

Regime. USB-modem: wired connection

Use of the USB-Internet cables are the choice of professionals who care about connection stability and minimal latency. Unlike Wi-Fi, the wired method is not subject to radio interference and does not drain the smartphone battery as quickly as the device receives power from the computer at the same time. To activate this mode, first connect your phone to your PC with a quality cable capable of transmitting data, not just charging.

After the physical connection, go to the Wi-Fi Access Point menu in the Android settings. USB-The modem will become active (no longer gray) only after the system detects the cable. Turn on this switch. Windows or macOS should automatically determine the new network connection and install the necessary drivers.

It's worth noting that in wired mode, the phone can request permission to access data. On the screen of the smartphone, a system window will appear with a question about the mode of operation. USB. Make sure you choose the option of File Transfer (MTP) or USB-If the computer can't see the Internet, try changing the modem. USB-port or cable, as cheap wires often don't have lines to transmit data.

⚠️ Attention: In active mode USB-The speed of transferring files between the phone and the computer can be limited, since the channel is occupied by Internet traffic.

Setting up APN and operator profiles

A key element of mobile Internet is the access point settings (APN). If these parameters are set incorrectly, the phone will show the network, but the Internet will not work. Usually Xiaomi automatically tightens the correct settings when installing a SIM card, but in case of failures or the use of rare operators, they will have to be manually registered.

To enter the settings APN Go along the way: Settings → SIM-maps and mobile networks → Choose your SIM card → Access points (APN). Here you'll see a list of available profiles. If none of them work, create a new hotspot by clicking on the plus or menu button. You'll need to enter the data that you can find on your carrier's official website.

It is important to fill in the APN fields, Username and Password correctly. Often, it is enough to only specify the name of the access point (for example, Internet or mts), leaving the remaining fields blank, but this depends on the tariff plan. Once you save the settings, be sure to restart the smartphone so that the changes take effect.

Use of Bluetooth modem

Although this method is considered obsolete due to the low data rate, it can still be useful in emergency situations where a small amount of text information needs to be transferred and other methods are not available.

To activate, you must first pair your smartphone with a computer or other device via Bluetooth. Go to Settings → Bluetooth, turn on the module and search for devices. After successful pairing, return to the Wi-Fi Access Point (or Connect and Share) menu and activate the Bluetooth modem.

On the computer side, you have to go to Bluetooth device settings, find your Redmi phone, and select a network connection option (PAN profile), which rarely exceeds 1-2 Mbps, so you don't have to rely on comfortable surfing or video, but it's a solution that's purely for light data or server management via SSH.

Operators’ Decisions and Limitations

Many users face a situation where the modem on Xiaomi is turned on, but the Internet on the connected device does not work, most often due to restrictions from the mobile operator, which blocks the distribution of traffic on tariffs without the appropriate option. Operators analyze the parameter TTL (Time to Live) passing data packets.

By default, Android value TTL When you plug in a laptop, that parameter decreases by one (it becomes 63), which signals the operator to distribute the Internet. TTL This requires obtaining superuser rights (Root) or using special applications that do not require root rights, but work through the creation of locally available data. VPN-tunnel.

If you have Root rights, you can change the system file. /proc/sys/net/ipv4/ip_default_ttl, fixation 65. The operator will then be able to reach the package with TTL 64, It will assume that the Internet is being used on the smartphone itself, and you can also try changing the User-Agent in the access point settings if your Redmi model allows you to do this through hidden menus.

⚠️ Warning: Changing network system settings can cause mobile internet to be unstable.Before making changes to the registry or system files, make sure you understand the risks, or create a restore point.

Optimizing energy consumption and safety

Modem mode, especially Wi-Fi, is one of the most energy-intensive processes in a smartphone. Active data transfer heats up the processor and the Xiaomi radio module, which leads to a rapid battery drain. To extend battery life, it is recommended to reduce the brightness of the screen or turn off the display after setting up, and close the background applications that consume traffic.

The MIUI hotspot settings have a useful shutdown timer feature, which you can set up to automatically shut down the modem if no one is connected to it for 5 or 10 minutes, which will save you from a situation where the phone has gone down to zero while you were busy doing other things.
