Many Xiaomi users experience situations where a desktop or laptop requires immediate access to the network and no wired connection is available. The built-in smartphone modem can turn your gadget into a full-fledged router, providing stable access to the global network for other devices, a solution that is especially relevant when traveling, when there are interruptions with the provider or in offices with limited infrastructure.
The process of activating modem modem in the shell MIUI or HyperOS implemented as intuitively as possible, but has a number of hidden settings that affect speed and security. Proper configuration of the access point will not only access sites, but also optimize traffic consumption. Below we will discuss in detail the algorithm of actions that will help you quickly establish a connection.
Before we get to the point, it’s important to note that the quality of the handout is directly dependent on the level of the cellular signal and the battery charge of your device. Using a smartphone as a router is a resource-intensive task that requires attention to energy saving parameters. Understanding these nuances will help to avoid sudden connection breaks at the most inopportune time.
Basic settings of Wi-Fi hotspot on Xiaomi
The first step to create a network is to go to the system settings menu. You need to find the section responsible for wireless connections. In modern versions of Xiaomi firmware, the path to the desired functionality is standardized, which makes it easier for even beginners to search. Open the Settings app and select Wi-Fi Access Point.
In the menu that opens, you'll see a switch that activates the modem, but it's not enough to run safely. You need to specify the network name (SSID) that will be displayed on your computer when you search for available connections. By default, the system suggests the name of the phone model, but it's better to change it to a unique one to avoid confusion in places with large crowds.
☑️ Pre-launch checks
The key element of security is password. The default system generates a complex combination of characters, which is recommended to be saved or changed to a memorable but reliable. Using open networks without a password is strongly discouraged, as this exposes your data to intercept. Make sure that the encryption standard is set to WPA2 PSK, as this provides the best balance of compatibility and protection.
⚠️ Warning: Do not use simple passwords like “12345678” or dates of birth. Attackers can quickly pick up this combination and use your traffic for illegal activities.
Advanced settings and frequency range selection
For users who want to make the most of their hardware, Xiaomi provides access to additional options. The access point menu often hides the option of selecting the frequency range. By default, the smartphone can operate in the 2.4 GHz band, which has greater range but less speed and is subject to interference from neighboring routers and microwave ovens.
Switching to 5 GHz allows you to significantly increase the data rate, which is critical for watching high-resolution video or downloading large files on a computer. However, it is worth remembering that the signal range at this frequency is smaller and it penetrates walls worse. If the computer is near the phone, choosing 5 GHz will be the best solution.
What is the difference between 2.4 GHz and 5 GHz?
Also, in advanced settings, you can change the maximum number of connected devices. Although theoretically a phone can serve up to 10 customers, real performance will begin to fall after 3-4 active users.
Connecting a computer to a smartphone network
Once the access point on Xiaomi is activated and configured, you need to pair with your computer. On a Windows PC, you need to click on the Wi-Fi icon in the tray (usually in the lower right corner of the screen). In the list of available networks, find the name you asked earlier.
Click on the Connect button and enter the password you previously set. The system will remember that connection, and in the future, the connection will happen automatically when you are within range. If you use macOS, the algorithm is similar: select the network in the Wi-Fi menu at the top of the menu and enter the security key.
It is important to monitor the connection indicator on the smartphone itself. At the top of the screen (in the notification curtain), an icon should appear indicating the number of connected devices or active distribution, which confirms that the data is transmitted correctly.
💡
If the computer can't see the network, try temporarily turning off the access point on the phone and re-energize it, which will update the signal and make the network visible to the PC's Wi-Fi adapter scanner.
Traffic Control and Data Limits
Mobile Internet, unlike home wired Internet, often has traffic limits. Uncontrolled distribution to a computer can lead to a quick exhaustion of a gigabyte packet, since the PC operating system is prone to background downloading updates and synchronizing cloud storage. Xiaomi offers built-in tools to monitor this process.
You can set a traffic limit in the access point settings, you can set a data limit, after which the distribution will automatically stop, it is effective protection against unintended deep down or slowdown by the operator, and you can also set a time limit, for example, turn off the distribution after 30 or 60 minutes of operation.
| Setup parameter | Recommended value | Impact on work |
|---|---|---|
| Traffic limit | Depends on the tariff (eg 2 GB) | Prevents overspending of money |
| Timer of shutdown | 30-60 minutes. | Saves battery life |
| SSID cover-up | Off (for home) | Increases safety in crowded areas |
| Range. | 5 GHz (if supported) | Increases loading speed |
In addition to software limits, consider the behavior of the computer itself, and it is recommended to disable automatic game updates on Steam, Epic Games or Windows updates before connecting, these processes can stealthily “eat” your entire data packet in minutes.
Connection problems and how to solve them
Despite the system’s fine-tuning, users may experience connection errors, and one common problem is the “No Internet” status of successful Wi-Fi connections, often indicating problems with carrier data transfers or incorrect APN settings that must be broadcast to the connected device.
In such cases, rebooting the communication module helps. 10-15 This action will force the phone to reconnect to the operator's base station and update it. IP-If the problem persists, check if the operator has blocked tethering, which is sometimes found in unlimited Internet tariffs.
⚠️ Note: Some carriers determine the distribution of traffic by value TTL. Bypassing this restriction requires root rights and system files to be modified, which may result in the loss of device warranty.
Another cause of failure may be energy saving: Aggressive MIUI settings can kill the distribution process to save energy. Go to the battery settings and make sure that the system services responsible for the access point have a "No restrictions" limit, which will allow the network to work steadily even with a locked screen of the phone.
The effect of Wi-Fi on battery and heating
The hotspot mode is one of the most energy-intensive for a smartphone, and the Wi-Fi module is constantly transmitting data at high frequencies, which leads to significant heating of the case, and prolonged operation in this mode can accelerate the degradation of the lithium polymer battery.
If you plan a long session, it is recommended to keep the phone connected to the charger, but in this case there is a risk of overheating, since the charging process also releases heat, it is optimal to remove the protective case and put the device on a hard, cold surface, such as glass or metal, for better heat sink.
💡
For a long Internet distribution, remove the case from your phone and put it on a cool surface to avoid trottling and battery overheating.
Watch the temperature of the device. If the phone gets hot to the touch, take a break or reduce the brightness of the screen, as the display also contributes to the overall heating. Modern Snapdragon and MediaTek processors used in Xiaomi have protection against overheating, but it is better not to bring the system to the limit values.
Alternative ways to connect: USB and Bluetooth
If the quality of the wireless signal leaves much to be desired or maximum stability is required, it is worth considering the wired option. USB-The cable allows you to charge your phone and transmit the Internet to your computer at the same time, which eliminates speed losses due to radio interference and provides minimal ping, which is important for online gaming.
For activation USB-modem connect the phone cable to the PC, go to the settings of the access point and select the item «USB-The computer automatically recognizes the new network connection, which is also preferred if the computer is malfunctioning or lacks a Wi-Fi adapter.
A Bluetooth modem is the least productive option, but it can save you in an emergency when other methods are not available. The transfer speed is much lower here, but it can be enough for texting or working with light web pages. It activates in the same connection settings menu.
