Modern Xiaomi and Redmi smartphones have long since ceased to be just call devices, becoming powerful tools for work and entertainment. One of the key features that ensures mobility is the ability to use the gadget as a router. This allows you to instantly provide Internet to a laptop, tablet or other phone anywhere there is coverage of the cellular network. However, standard settings are not always obvious, and hidden parameters can dramatically affect the speed and stability of the connection.
Owners of devices with a MIUI shell or a new HyperOS often face the nuances that distinguish their smartphones from pure Android. The settings interface here is more detailed, offering a choice of frequency ranges, traffic limits management and energy saving settings. Understanding these parameters will not only help to distribute the network quickly, but also optimize battery life, and secure the data channel from unauthorized connections.
In this article, we will take a closer look at the entire configuration process, from basic powering to advanced 2.4GHz and 5GHz manipulations. You will learn how to hide your network, set up automatic shutdowns and solve typical problems when other devices simply can’t see the hotspot created.
Basic mode activation through settings
The easiest and most obvious way to start the Internet distribution is in the system menu. First, you need to lower the notification curtain and find the Access Point icon. If it is not on the first screen, click on the edit pencil and drag the icon to the active area. Once activated, the system will automatically turn on the Wi-Fi module if it was turned off, and begin broadcasting the network with a name consisting of your phone model.
However, a deeper setup is required to work properly. Go to Settings menu → Connection and Sharing → Wi-Fi Access Point. This shows the network name and default password. By clicking on these fields, you can change them to more convenient and difficult combinations. Using a simple password like “12345678” is highly undesirable, as it opens up access to your traffic to any passer-by.
In the same section, you need to pay attention to the Hide Device Switch, which if you activate this feature, your phone will stop broadcasting the network name on the air, other users will not be able to find your hotspot in the general list of available networks, you can only connect to it manually by entering the exact name (SSID) and password, which is a great way to protect in crowded places where there is a high risk of man-in-the-middle attacks.
Also on the "Allow Sleeping Connection" switch is here. By default, Xiaomi's system can turn off the hotspot to save power if the smartphone screen goes out. If you plan to download large files to a connected laptop, this option must be activated, otherwise the download will stop after a few minutes of phone downtime.
Choice of frequency range: 2.4 GHz or 5 GHz
One of the most important things that affects data speed is the choice of frequency range. In the access point menu, look for "Access Point Frequency Range." Here you will be given a choice between 2.4 GHz, 5 GHz or automatic mode, and understanding the difference between them is critical for stable work.
The 2.4 GHz range is more common and compatible. It provides better coverage and the signal's ability to bend obstacles like walls or furniture. However, this range is often overloaded: microwaves, Bluetooth devices and neighborhood routers run, which can lead to slowing speeds and increasing ping. If you're in an apartment building, this option may not be the most productive.
The 5GHz range offers significantly higher speeds and less interference, because there are more channels and they are less busy. However, it has a smaller range and it penetrates hard obstacles less easily. If the laptop is in the same room as the phone, choosing 5GHz will give you maximum performance for streaming or online gaming.
Automation allows the system to make its own decisions based on the connected devices. If the old gadget does not support 5 GHz, the phone will switch to 2.4 GHz. For most users, this is the best option, but if you want guaranteed high speed for a particular device, you better prioritize manually.
⚠️ Warning: When switching to 5GHz, older devices (released more than 10 years ago) may simply not see your network.If a laptop doesn't find an access point, try forcefully setting 2.4GHz.
Security setting and management of connected devices
The security of your mobile Internet is not only a complex password. There are several layers of protection in the settings of the Xiaomi hotspot. First of all, make sure you choose the type of WPA2 PSK encryption or the more modern WPA3 if your device supports.Outdated protocols like WEP or open networks without a password make your data vulnerable to interception.
An important feature is the "White List" of devices, and by activating it, you only allow the connection to those gadgets whose devices are not connected. MAC-Adding a device is a regular way to connect it, and then clicking on Connected Devices in the access point menu and selecting the access restriction option.
It also lets you see who is using your traffic right now, and the Connected Devices menu displays a list of all active customers, with the name of the model and the amount of traffic you consume, and if you notice an unknown device, you can instantly lock it by clicking on the appropriate button, which will break the connection and prevent re-authorization.
Don't forget traffic limits. You can set a data limit in your settings, and then the access point will automatically shut down, which will save you from unintended packet megabytes of consumption if you're watching high-resolution video over a mobile network.
☑️ Network security check
Solving Visibility and Connection Problems
Sometimes users are faced with a situation where the access point is turned on, but other devices can not see it or can not connect. IP-In this case, a simple but effective method helps: turn on flight mode for 10 seconds, and then turn it off.
Another common problem lies in the settings. APN (If the Internet on the phone itself works but is not being distributed, check the settings of the mobile network. APN Or, conversely, reset them to factory values. → SIM-maps and mobile networks → Access points (APN).
Also, consider that some mobile carriers’ tariffs prohibit or restrict the distribution of the Internet (tethering technology). The operator can determine the distribution by the TTL parameter. In this case, the connection may occur, but the pages will not load. To circumvent this restriction, more complex manipulations are required with changing the TTL in the engineering menu, which is beyond the standard setting.
If the devices are connected but there is no internet, try the Forget Network on the receiving device and reconnect, and make sure that the phone that distributes the internet does not have a traffic saving mode that can block background data transfers to other devices.

Comparison of Distribution Methods: Wi-Fi, USB and Bluetooth
In addition to the classic Wi-Fi, Xiaomi smartphones allow you to use the USB-And each method has its own advantages and disadvantages, which should be considered depending on the situation. Below is a table comparing these technologies by key parameters.
| Parameter | Wi-Fi Access Point | USB-modem | Bluetooth panorama |
|---|---|---|---|
| Speed. | High (up to 100+ Mbps) | Maximum (stable) | Low (up to 2 Mbps) |
| Energy consumption | High. | Low (PC charge) | Average. |
| Convenience | Wireless, up to 10 devices | Only 1 device, you need a cable. | Wireless, complex setup |
| Delay (Ping) | Medium | Minimum | Tall. |
USB-The modem is the perfect solution for stationary work behind a laptop, not only provides a stable Internet without loss of packets, but also charges the phone at the same time, it is the best choice for gamers or those who need to download a large file without the risk of draining the smartphone.
Bluetooth is rarely used today because of its low speed, but can be useful in emergency cases where you need to transfer a small text file or message and the Wi-Fi module is damaged. → Pairing. → Internet access.
The choice of method depends on your priorities: speed and stability (USB), mobility and multiconnection (Wi-Fi) or resource savings in the last resort (Bluetooth).
💡
Use quality. USB-Cheap gas cables often only support charging and don't transmit data, making it impossible for the computer to see modem.
Optimizing energy consumption and extending work
Internet distribution is one of the most energy-intensive processes for a smartphone. Active operation of two radio modules (receiving 4G/5G and transmitting Wi-Fi) causes strong heating and fast battery discharge. To minimize losses, the settings of the access point Xiaomi has a shutdown timer.
The "Switch Off hotspot" feature allows you to set a time interface (e.g., 1.5 or 10 minutes) through which the system will turn off the hotspot if no one is connected to it, preventing you from forgetting to turn off the distribution and the phone will run out of your bag in a couple of hours.
It's also worth disabling unnecessary features during the handout: closing background apps, reducing screen brightness and turning off GPS This will help reduce the overall load on the processor. USB-modem, the phone will charge from the computer, but if the charging speed is lower than the discharge speed (which happens with old ones). USB-Port 2.0, battery will still lose charge, albeit slower.
It's important to monitor the temperature of the case. If the phone overheats, the system will force the data rate to slow down or completely turn off the communication modules to protect the hardware. In hot weather, it's better to remove the case and put the phone on a cool surface or in front of the fan.
💡
Optimal strategy: use a timer auto-disconnect and connect the phone to the charger for long periods of operation in router mode.
