The pace of life dictates its rules, and access to the global network becomes a necessity at any moment. Situations when you urgently need to transfer a large file, check your email on a tablet or simply provide a stable connection to a friend's laptop, arise regularly. Owners of Xiaomi, Redmi and Poco devices often wonder how to activate the Internet distribution function as efficiently as possible, so as not to waste battery power and ensure high data transfer speeds.
MIUI, the operating system that underpins the interface of the brand’s smartphones, has powerful network connectivity management capabilities that allow you to not only turn on the access point, but also fine-tune its parameters, limit the number of devices you connect to, and even hide the network from prying eyes. Understanding these nuances will help you become a true master of mobile communication.
In this article, we will take a closer look at all the ways to activate modem mode, explore the hidden features of the interface, and answer the most common questions users have, learn how to optimize settings for better performance and what to do if other devices do not see your network.
Preparation of the smartphone to work in the router mode
Before you start setting up, make sure your smartphone is ready to work as an internet source. First of all, check the cellular signal strength and the tariff plan balance. Traffic distribution, especially in 4G or 5G format, can consume megabytes very quickly, so make sure you have an unlimited package or sufficient data.
Also worth paying attention to the battery charge: the access point mode significantly increases power consumption, since the radio module is in a high mode. If the battery charge is below 20%, it is recommended to connect the device to the charger before handing out.
- 📱 Make sure mobile data is enabled in the notification curtain.
- 🔋 Check the battery level, it should be above 30%.
- 📶 Make sure you are in a network signal receiving zone.
- ⚙️ Update your operator’s settings if you have recently changed SIM-map.
⚠️ Warning: When the hotspot is active, the phone may feel appreciably warmer. This is normal physical, but if the temperature becomes critical, the device can automatically turn off the communication module to protect components.
To work smoothly, it is advisable to close the background applications that actively use the network, such as file downloaders or streaming services on the phone itself, which will allow you to direct the entire channel to the connected devices.
Standard activation of the Wi-Fi access point
The most common way to share the internet is by using a built-in Wi-Fi module. MIUI offers several ways to enable this feature, making the process easy for anyone to use. The standard procedure takes only a few seconds.
The first and fastest method is to use a notification curtain, swipe down from top to top to open the control center, and find the Access Point icon (often looks like two connected circles or an antenna), which will activate the mode, and the long one will throw into the settings menu.
If you prefer a classic menu, follow the following steps:
☑️ Pre-insertion check
Click on the Settings icon on your desktop or app menu. In the list that opens, look for Wi-Fi Access Point. In some versions of the firmware, it may be inside the Connect and Sharing menu. Move the slider to the active position.
You can change the network name and password here, and by default, the system generates a random name, but for personal use, you'd better give a clear name, like, for example, a name that's not a random name, «My_Xiaomi_Net». Passwords should be complex enough so that neighbors can’t connect to your traffic without permission.
Advanced settings and hidden capabilities
Many users don’t realize that the standard menu is just the tip of the iceberg. Deep in the Android settings based on MIUI, there are parameters that allow you to manage the frequency range and security protocols, this is especially true if the connected devices are old or, conversely, very modern.
In the access point menu, find "Setting up the access point" or "More." There's a choice of frequency range available. The default is often "2.4 GHz," which provides good range but less speed. Switching to "5 GHz" will significantly increase data speed, but the signal range will decrease, and older devices may simply not see the network.
What gives a 5GHz range?
You can also set the maximum number of connected users here, so if you only give out the Internet for one laptop, limit the number to 1 or 2, which will prevent unauthorized connection of unnecessary gadgets and save battery power.
- 🔒 Security Protocol: Choose from the WPA3-Personal Maximum protection if the devices are supported.
- ⏱️ Shutdown timer: set to automatically shut down the access point if no one is connected to it within 10 minutes.
- 📱 White List: In some versions MIUI The connection permission function is available only for specific MAC-address.
And the AP Band is a big consideration, and if you're having problems with speed on a connected device, try to force that to change, and often the automatic choice is not optimal in a noisy apartment building.
Distribution of Internet via USB and Bluetooth
While Wi-Fi is the most popular method, there are situations where wireless connectivity is not possible or desirable, such as when the phone’s battery is critically low, or maximum connection stability is required to operate.
USB-A modem is a great choice for connecting a laptop or a desktop computer, in which case the smartphone not only transmits the Internet, but also charges from the computer port, which solves the problem of autonomy. To activate, connect the phone with a cable to the PC, wait for the driver installation (if required) and turn on the switch in the access point menu «USB-modem».
The system will automatically turn off Wi-Fi on the phone and redirect traffic through the cable, which is usually faster and more stable than over the air, and the delays (ping) are minimal, which is important for online games or video conferencing.
💡
Use the original cable to connect USB-Cheap charging-only cables have no data lines and will not allow modem modem activation.
Bluetooth panning is an older, slower method, but it can save you in an emergency when you need to send a little text or mail and the Wi-Fi module is damaged or busy, and the speed here is limited by the Bluetooth protocol, so you can't watch video.
To set up a Bluetooth connection, you first need to pair between devices in the Bluetooth menu, and then turn on the “Bluetooth modem” in the access point settings. On the receiving device, you will also need to choose how to connect via a Bluetooth LAN.
Troubleshooting and troubleshooting
Despite the system's fine-tuning, users sometimes run into problems: the phone doesn't give out the Internet, the devices don't see the network or the connection is there, but the pages don't load, most often due to APN settings or a temporary radio failure.
If other devices see the network, they can’t get it. IP-address, try changing the security type. WPA3 on WPA2/WPA Mixed often solves the problem of compatibility with old gadgets, and also helps a simple reboot of the smartphone-distributor.
| Problem. | Possible cause | Decision-making |
|---|---|---|
| Devices don't see the network | Frequency range incorrect | Change in settings from 5 GHz to 2.4 GHz |
| No Internet access | Wrong APN settings | Reset the settings of the access point to the factory |
| Low speed. | Lots of connected devices | Limit the number of users on the menu |
| The battery goes down fast. | High power mode | Use it. USB-modem or power bank |
Another common reason is that the carrier has blocked distribution, some plans prohibit the use of the phone as a router or require a surcharge for this service, check the terms of your tariff in the operator's personal account.
⚠️ Note: If you have changed your settings APN and the Internet is gone completely (even on the phone itself), find the button "Reset" or "Restore by default" in the settings menu of the mobile network.
Traffic security and control
When you turn your Xiaomi into an access point, you become a mini-network administrator. It's important to keep track of who's connected to your site. The access point menu always shows a list of active customers from their sites. MAC-address.
Check this list regularly. If you see an unfamiliar device, change your password immediately. Using a complex password is the first and foremost line of defense. Don't use simple combinations like "12345678" or date of birth.
Also worth remembering is traffic consumption: A connected laptop can start updating the operating system or downloading games in the background, considering the connection to be free home Wi-Fi. This can lead to a rapid exhaustion of the limit of your mobile package.
- 👁️ Check the list of connected devices in the curtain or settings regularly.
- 🚫 Turn off the access point immediately after use.
- 📉 Keep track of traffic consumption in the Security app or in settings SIM-map.
💡
The main principle of security is a complex password and constant monitoring of the list of connected devices.
For additional control, you can use third-party applications from Google Play, which are able to block network access for specific devices. MAC-The address, even if they know the password, is standard. MIUI Usually enough for basic protection.
Impact of Distribution on the Battery and System
The access point mode puts a high strain on the processor and radio module of the smartphone, which leads to increased heat generation, and in the summer or when in the sun, the phone can heat up to temperatures at which the system will begin to artificially underestimate performance (trottling), which will affect Internet speed.
To minimize battery wear, try not to keep your phone in active distribution mode for hours without interruption. If you need a long-term connection, it is better to use it. USB-modem with connection to the power network or purchase a special portable router (MiFi), which is created for such tasks.
Why does the phone warm up when handed out?
Owners of fast-charging models may not be as worried if they use the USB-modem, because the power is offsetting the energy costs, but wireless distribution on weight or in a case with poor heat transfer can lead to overheating.
