Modern smartphones line Xiaomi Redmi long ceased to be just devices for calls, becoming a full-fledged control center of the digital space, including the function of distribution of the Internet. Situations when you urgently need to provide access to a laptop or tablet, and a stationary router at hand, occur everywhere: in the train, cafe or temporary interruptions at the provider. Built-in modem devices with the shell of MIUI or the new HyperOS allows you to instantly turn the smartphone into an access point, but the default settings do not always provide maximum speed or security.
Unlike many other manufacturers, Chinese engineers have introduced advanced wireless interface management capabilities into their devices, which are often hidden in the depths of the system menu. The user can not only specify the network name and password, but also choose the frequency range, limit the number of devices connected, or even hide the network from prying eyes. Understanding these nuances will help you not only distribute the Internet, but also make this process as efficient and secure for your data.
In this guide, we will take a look at all aspects of creating a mobile hotspot on Redmi Note, Redmi Pro and other models of the brand. We will touch on the technical features of the communication modules, the difference between 2.4 GHz and 5 GHz, and also look at ways to optimize power consumption. Deep immersion in settings will allow you to avoid the typical errors when devices see the network but can not connect, or when the connection speed drops to unacceptable values.
Basic activation of the access point through the curtain and settings
The fastest way to activate modem modem mode is to use the control panel, which is accessed by swipe down from the top edge of the screen. In a standard set of icons, there is usually an access point element, which, when pressed, instantly triggers the distribution process. If the icon is absent in the visible area, you need to click on the edit button (usually a pencil icon or a tripodle) and drag the desired module into the active zone. This method is ideal for situations where you need to quickly give access to guests without going into fine settings.
However, for the initial configuration or change of security settings, you will need to go to the system menu. The path may vary slightly depending on the firmware version, but the general logic remains: you need to open Settings, find the Connection and Sharing section (or simply “Additional Features” in older versions of MIUI), and select the Wi-Fi Access Point. This is where the key switches determine who can use your traffic and how.
When you first turn on, the system will prompt you to specify a network name (SSID) and password. It is recommended that you immediately change the standard name containing the phone model to something less informative for outsiders. The password should be complex, contain letters of different registers and numbers to prevent you from selecting the encryption key by brute-force. Once you save the changes, the smartphone will begin to broadcast the signal, and other devices will be able to detect it in the list of available networks.
⚠️ Note: When activating the access point, the mobile Internet switches to a constant data transfer mode, which can lead to rapid battery discharge and heating of the device body, especially when using cases with poor heat transfer.
Security setting and management of connected devices
Security of data is a priority, so the menu of the access point Xiaomi provides a choice of encryption protocol. by default, WPA2 PSK is usually installed, which provides reliable protection for most use cases. New models with support for modern standards may have the option WPA3, providing an even higher level of crypto-resistance, but older devices (released more than 10 years ago) may simply not see your network when choosing this protocol.
The white list function (or filtering by MAC-It allows you to create a list of devices that you can connect to, and all other gadgets, even if you know the right password, can't log in, and it's a very useful option in public places where you can theoretically go through passwords. You can see a list of all current connections at the bottom of the access point settings menu, where the device names and the amount of traffic they consume are displayed.
To maximize privacy, it is possible to hide the access point, in which case the network will not appear in the general list of available connections on other devices. To connect to the hidden network, the user must manually enter the exact name (SSID) in the Wi-Fi settings on the client device and select the type of security, which creates an additional barrier for casual users looking for free Internet.
☑️ Network security check
Technical parameters: frequency choice 2.4 GHz or 5 GHz
One of the most important settings affecting connection speed and stability is the choice of frequency range. In the Access Point Settings menu -> Frequency range, the user can choose between 2.4 GHz and 5 GHz. The 2.4 GHz range has better penetration and compatibility: it “breaks through” walls and is supported by absolutely all devices, including old laptops and budget tablets. However, this range is often overloaded with signals from neighboring routers, microwaves and Bluetooth headsets, which can reduce real speed.
The 5GHz band provides significantly higher data rates and is less prone to interference, as it has more channels and is less crowded. It is the ideal choice for watching 4K video, online gaming or downloading large files to a laptop in the vicinity of a smartphone. The downside is the shorter range and the worse ability to bend obstacles: a single concrete wall can significantly weaken the signal.
Some modern Redmi models support smart switching or network mapping, but more often, you should make the choice manually depending on the situation. If you are in a dense urban development or apartment building, experimenting with switching to 5 GHz can give a noticeable increase in performance. If the devices are in different rooms, it is better to stay at 2.4 GHz to maintain the stability of the connection.
Why does 5GHz work faster?
Advanced MIUI settings and hidden features
The MIUI shell that is installed on Xiaomi smartphones offers a number of unique features that are not available in pure Android. For example, you can set a traffic limit for the access point. You can set a limit, after which the Internet distribution will automatically turn off, which saves from inadvertently spending all packet traffic if you forgot to turn off modem mode after you finish.
Another useful feature is a shutdown timer. If you only need the Internet for a short time, you can set up an automatic shutdown of the access point after 10, 30 or 60 minutes of downtime or work. This helps save battery power, since the Wi-Fi module in the handout mode consumes energy much more actively than in the reception mode.
Owners of Wi-Fi 6-enabled devices (802.11ax standard) may notice improved performance in a multitude of connected clients. OFDMA protocol, used in Wi-Fi 6, allows you to more effectively manage data flows, reducing delays (ping) when multiple devices are running simultaneously.
| Parameter | 2.4 GHz | 5 GHz |
|---|---|---|
| Transmission speed | Up to 150-300 Mbps | Up to 400-800+ Mbps |
| Radio of action | Tall (up to 50 m) | Medium (up to 20-30 m) |
| penetrating ability | Good. | Low. |
| Level of interference | High-pitched | Low. |
Solving Common Connection Problems
Often users are faced with a situation where the laptop sees the network, but can not connect to it, issuing an error “failed to connect” or endlessly trying to get a network. IP-The first step in diagnosis is always to check the password format and encryption type, sometimes it helps to temporarily disable the password to check the health of the channel, after which the protection should be returned immediately. Also, make sure that the smartphone is not activated power saving mode, which can aggressively limit the background operation of the Wi-Fi module.
Another common problem is that devices are connected, but the Internet is not working, although the mobile network catches perfectly. APN (access points) on the mobile Internet. Sometimes operators block the distribution of traffic to certain types of devices or require special profile settings. 4G/LTE on 3G and back to initiate reconnection to the operator gateway.
If none of the methods works, the effective solution is to reset the network settings. This action will delete all stored Wi-Fi passwords and Bluetooth settings, but often eliminates software conflicts in network modules. The path to reset: Settings -> Connection and Sharing -> Reset Wi-Fi, mobile networks and Bluetooth. Once the phone is rebooted, you will need to re-enter passwords from known networks.
⚠️ Note: Some mobile operators may block or charge separately traffic that goes through modem modem modem (Tethering).Be sure that your plan allows you to do this without additional payments before actively distributing.
Optimization of energy consumption and work in the background
Wi-Fi distribution is one of the most energy-intensive processes in a smartphone. The communication module runs at maximum power, the processor processes network packets, and the screen is usually turned off, which prevents the user from seeing status. To extend battery life, it is recommended to reduce the brightness of the screen before handing out, or use the “Do not turn off the screen” function only when you need control.
The MIUI system can force the access point to be turned off if it thinks it's not being used to save battery life, and to avoid that, you need to go to the battery settings, find the Access Point app (or the system process that controls the hotspot), and set background activity limits in No Limits mode, which will prevent the system from strangling the distribution process to save energy.
If you're working in modem modem for a long time, the phone can get warmer. This is a normal physical reaction, but critical overheating can lead to trottling (decreased performance) or a temporary shutdown of the module. If you plan a long session, it's best to remove the case from the phone and put it on a cool surface, avoiding direct sunlight. Using the original cable and power supply (if the phone is connected to charging) will also help stabilize the temperature regime.
💡
For maximum stability during long-term operation in modem modem, turn on Flight mode for 5 seconds, and then turn it off. This will restart all radio modules and update the registration in the operator's network.
Alternative ways of distributing: USB and Bluetooth
If the Wi-Fi module is damaged or the most stable connection with minimal latency is required, you can use the device. USB-To do this, just connect the smartphone to the computer with a cable, go to the menu Access Point and modem and activate the item. USB-The computer recognizes the phone as a wired network device, and the advantage of this method is that the phone charges at the same time, and the connection speed is limited only by the capabilities of the device. USB-port and mobile Internet speed, without loss on the radio channel.
A Bluetooth modem is the least productive, but sometimes the only option possible. It's suitable for sending small amounts of text or mail when other methods are not available. The speed here will be low, and the setup will require pairing devices via a Bluetooth menu and then selecting the "Internet Access" option in the properties of the connected device. For video or games, this method is categorically not suitable due to high ping and low bandwidth.
The choice of method depends on your current tasks and equipment condition: Wi-Fi is versatile and user-friendly for a group of devices, USB is ideal for stationary work with a laptop, and Bluetooth is an emergency option. Understanding the differences allows you to flexibly manage the connection in any environment.
💡
USB-The modem provides not only a stable connection without radio interference, but also prevents the discharge of the smartphone, since the power comes from the computer.
