The modern smartphone has long since ceased to be a mere means of communication, becoming a full-fledged control center for the digital world, and the Internet distribution function is one of the most popular features. Owners of Xiaomi, Redmi and Poco devices often use their gadgets as mobile routers to provide Wi-Fi access to laptops, tablets or other phones when traveling, offices or places with poor coverage of a stationary provider.
The process of activating modem modem on the shell of MIUI or HyperOS is implemented quite intuitively, but hides a lot of subtleties that are not known to all users. From the choice of signal frequency to the setting of the traffic limit, each parameter affects the stability of the connection and data transfer speed. The correct configuration helps not only to quickly connect to the network, but also to optimize the battery consumption of the smartphone.
In this article, we will take a look at all the available ways to distribute the Internet, explain the difference between protocols and frequencies, and also consider the frequent errors that occur when connecting third-party devices. You will learn how to set up a guest network, secure your data and what to do if your laptop “does not see” the access point. Understanding these nuances will turn your Xiaomi into a reliable tool for work and entertainment.
Basic setting of the Wi-Fi access point
The most common and convenient way to share the Internet is to create a wireless hotspot. You need to go to the settings menu of your device. On modern versions of the MIUI shell, the path usually looks like: Settings → Wi-Fi Access Point. In some cases, this item may be called a Portable Hotspot or located under Connection and Sharing.
Once you log in, you'll see a switch that activates the handout mode, but simply turning it on isn't enough to work safely. The first thing you need to do is click on the network name (it often contains a phone model by default, like the Redmi Note 10), and change it to any name you like so you don't get confused about the network list.
A critical step is to set a password.Use a combination of numbers and letters at least 8 characters long so that outsiders can't connect to your traffic without permission.The standard WPA2 PSK encryption protocol is the optimal choice for most situations, providing a balance between compatibility and security.
☑️ Set up a secure access point
Remember that active Wi-Fi distribution significantly increases the load on the processor and radio module of the smartphone. If you plan to use the access point for a long time, it is recommended to connect the device to a charging or external battery.
Frequency and range settings: 2.4 GHz or 5 GHz
One of the key settings that is often ignored is the choice of frequency range. In the menu of the Xiaomi access point, there is an option “Access Point Frequency Range” where you can choose between 2.4 GHz and 5 GHz. Understanding the difference between them will help you achieve maximum speed or better coverage depending on the situation.
The 2.4 GHz band is more versatile and compatible. It provides a signal that travels through walls better and is captured even by older devices that don't support the new standards. However, the data speeds here are lower, and the range itself is often "clogged" with signals from neighboring routers, microwave ovens and Bluetooth devices, which can cause interference.
Choosing a 5GHz band is relevant if you want high speed and minimal latency, such as for online gaming or watching 4K video. This range is less crowded but has a shorter range and is worse at penetrating obstacles. Also, many older laptops and budget gadgets simply won’t see a network running at this frequency.
- 📶 2.4 GHz: Better coverage and compatibility, but lower speed and more interference.
- 🚀 5 GHz: High speed and stability, but shorter range.
- 📱 Compatibility: Check if the receiving device supports 5GHz before switching.
If you're not sure which range to choose, leave the Preferred or Auto setting and the system will try to find the best option for you. However, in an apartment building where the air is crowded, manual switching to 5 GHz often works wonders with Internet speed.
Why 5GHz might not work?
Distribution of the Internet through USB-cable
When the wireless connection is unstable or maximum lossless speed is required, a wired connection comes to the rescue. USB-The modem not only allows you to transmit the Internet, but also to charge your smartphone at the same time, which solves the problem of fast battery discharge, a method that is especially popular among owners of desktop computers that do not have Wi-Fi modules.
To activate this mode, you will need a proper USB-cable, preferably original or certified, capable of transmitting data, not just current. Connect your smartphone to your computer, then go to the Settings menu. → Wi-Fi hotspot. There you'll find a hotspot «USB-modem that will become active only after a successful connection to the PC.
The computer recognizes the phone as a new network device. In Windows Device Manager, this can be displayed as "Remote NDIS based Internet Sharing Device." If the drivers are not installed automatically, the system may take several minutes to find and install them, after which the Internet should appear automatically.
| Parameter | Wi-Fi access point | USB-modem | Bluetooth modem |
|---|---|---|---|
| Speed. | High (depending on range) | Maximum (stable) | Low. |
| Battery consumption | High-pitched | Charging the device | Medium. |
| Number of devices | Up to 10 and more | Only 1 PC. | Only 1 device. |
| Convenience | Wireless. | Cable required | Tough setup |
It is important to note that when using USB-Some antivirus or enterprise security policies may block the connection, perceiving the phone as a potentially dangerous network device.
💡
USB-The modem is the only way to simultaneously get the maximum speed of the Internet and charge the phone, avoiding overheating during wireless transmission.
Using Bluetooth to distribute the network
Although this method is considered obsolete due to the low data rate, it can still be useful in emergency situations when the Wi-Fi module is damaged or you need to connect a device that does not support standard protocols.The speed of the Bluetooth modem rarely exceeds 1-2 Mbps, which is enough only for instant messengers or download simple web pages.
The setup process requires pairing devices. On a Xiaomi smartphone, turn on Bluetooth and search for devices on your computer or tablet. Once you create a pair and confirm the security code, on a computer in the list of Bluetooth devices, you need to select your phone and click Connect via» → «Access point».
On the phone itself, you also need to activate the appropriate switchboard in the access point menu. Unlike Wi-Fi, you don't need to enter a password every time, since authorization occurs at the interface level, but the range of this connection is extremely small and rarely exceeds 5-7 meters of line of sight.
The main disadvantage of this method is that it uses very little power, and the processor has to keep the connection active, converting data packets, which leads to rapid heating, and use this method only when other options are physically unavailable.
Traffic Limits and Connected Device Management
Mobile Internet is rarely unlimited, so controlling traffic consumption becomes the number one task. The MIUI shell provides built-in monitoring tools. The access point menu allows you to set a traffic limit: when a given amount of data is exhausted, the distribution will automatically turn off, saving your balance from unpleasant surprises.
You can also see a list of all the connected devices in real time, which shows the names of the gadgets and the amount of traffic they consume, and if you notice an unfamiliar device, you can lock it with a single click, changing the password to prevent unauthorized access.
To fine-tune it, you can use the Timer feature, which allows you to set the time at which the access point will turn off automatically, which is useful if you give the Internet to a friend for a short time or want to make sure you don't forget to turn off the distribution at night.
- 📊 Monitoring: Regularly check the list of connected customers.
- ⏱ Timer: Set automatic shutdown to save charge.
- 🚫 Blacklist: Block suspicious devices instantly.
⚠️ Note: When setting a traffic limit, keep in mind that system updates to apps on connected devices can eat the entire package in minutes. 10-15%.
Solving Connection Problems and Errors
Despite Xiaomi’s stability, users may experience a situation where devices can’t see the network or can’t connect. IP-In this case, it helps to reboot the network on the smartphone or forget the network on the client device, followed by re-entering the password.
Another common problem is channel range: Some older network cards don't support channels above 11 or specific channel widths. If the laptop doesn't see the network, try the advanced access point settings (via an engineering menu or third-party utilities if the standard menu doesn't give you a choice) to change the channel to a lower one, for example, from 36 to 1.
If there is internet on the connected device, but the pages do not load, check the settings. DNS. Sometimes the mobile operator's provider will block requests that are not coming from the phone itself, in which case it may help to turn on flight mode for 10 seconds to reconnect to the tower with the update. IP-address.
💡
If the access point spontaneously shuts down after 10 minutes without connections, this is normal. In the battery settings, set the "Access Point" mode for the "No Limits" process so that the system does not "kill" the background service.
