The modern smartphone has long ceased to be just a means of communication, becoming a universal tool for work and entertainment. Owners of the popular Xiaomi Redmi 8 model often face the need to provide access to the network to other devices, whether it is a laptop, tablet or phone of a friend. The function of the access point in this model works stably, but has its own configuration features in the shell of MIUI, which must be considered for proper operation.
Internet distribution requires not only the activation of the appropriate switch, but also the correct configuration of the frequency range, security password and, if necessary, limit the traffic consumed. Incorrect setup can result in connected devices simply not seeing the network or not being able to access the network. IP-In this article, we will discuss all the nuances in detail so that you can quickly organize your personal Wi-Fi zone anywhere in the world.
It is important to understand that modem activation significantly affects battery power consumption. Redmi 8 has a 5,000 mAh battery, which allows you to run in router mode for quite a long time, however, the processor and communication module will work under increased load. Before you start setting up, make sure that you have mobile Internet enabled and have an active tariff plan with enough traffic.
Basic activation through the notification curtain
The fastest way to launch an access point is to use the Quick Access Bar. To do this, swipe from the top edge of the screen down to open the notification curtain. Among the icons, find a symbol resembling an antenna or a key that is signed as "Access Point" or "Hotspot." If you don't see this icon right away, try swiping left or clicking on the menu edit button (usually a pencil or three dots).
Once you click on the icon, the system will automatically turn on the Wi-Fi module in the handout mode. However, if you launch the feature for the first time, Android may request confirmation or offer to adjust security settings. Without a password, outsiders will be able to connect to your network, which will lead to traffic leakage and reduced connection speed. So even with a quick activation through the curtain, it is strongly recommended to go to the full settings at least once to set a reliable access key.
Some versions of MIUI firmware may have a pop-up when turned on through the curtain, suggesting you choose a frequency range. By default, the system often chooses 2.4 GHz for maximum compatibility, but if your devices support 5 GHz, it's better to switch to this standard for higher data rates. This is especially true when watching high-resolution video on a connected tablet.
Configure the access point parameters in the menu
For deep configuration, go to the main settings menu of your smartphone. Find Settings → Wi-Fi Access Point. In some versions of the shell, this item may be inside the Connection and Sharing or Additional Features category. This is where all the controls of your wireless network, including name, password and hidden settings, are located.
The first thing that catches your eye is the SSID or Access Point Name field, which contains a phone model like the Redmi 8 by default, but you can change it to any name you like using Latin letters and numbers. The password box below is a mixed type of WPA2 PSK encryption, which provides the best balance between security and compatibility with older devices.
☑️ Checking security settings
The "Frequency Range" item deserves special attention. If you choose 5.0 GHz, the data rate will be higher and the interference from neighboring networks will be less, but the range of the signal will be significantly reduced. The 2.4 GHz range is better penetrates walls and works at a greater distance, but can be loaded with other devices, such as microwaves or Bluetooth headsets. The choice depends on your current conditions and speed requirements.
⚠️ Warning: Don’t use simple passwords like “12345678” or date of birth, and attackers can quickly pick up the combination and use your connection for illegal activities, as well as overload the channel, which will cause your phone to warm up a lot.
Traffic Limitation and Connection Management
MIUI not only allows you to distribute the Internet, but also to control its consumption. This is critical for tariffs with a limited package of gigabytes. In the menu of the access point, find the item "Limit traffic" or "Limit traffic", Here you can set a limit value, after which the distribution will automatically cease.
It also allows you to see a list of all the devices that are currently connected, so you can track in real time who is hanging on your network, and if necessary, block unknown gadgets. IP-address and volume of data transferred, which helps to identify “heavy” users downloading large files.
| Setup parameter | Recommended value | Impact on work |
|---|---|---|
| Frequency range | 2.4 GHz (universal) | More radius, more interference. |
| Encryption | WPA2-Personal | Protection against password cracking |
| Time out | 10 minutes. | Savings in battery life without customers |
| Max. Connections. | 4-5 devices | Reducing the load on the processor |
It's also useful to set up an automatic shutdown of the hotspot if no one's connected to it for a long time, called "Time Out," which helps to keep the battery power if you forget to turn off the modem mode after use, usually setting a 5-10 minute value.

Distribution of Internet via USB and Bluetooth
Apart from classic Wi-Fi, the Xiaomi Redmi 8 supports Internet connection transmission via USB cable or Bluetooth protocol, which are less popular because of the slower speed, but can be indispensable in situations where the computer's Wi-Fi module is faulty or requires maximum stability of the connection without radio interference.
For activation USB-Modem connect your phone to your computer with a cable. From the access point settings menu, select the item «USB-The modem (it will only be active when the cable is connected) will recognize the phone as a new network device, and the advantage of this method is that the phone will simultaneously charge from the PC port, offsetting the energy costs of data transfer.
The Bluetooth modem is slower and requires device pairing. After pairing your phone and laptop in the Bluetooth settings on your computer, select the "Connect through" option → "Access Point." The speed here rarely exceeds 1-2 Mbps, which is enough only for texting or navigation, but not for multimedia.
💡
In the case of USB-Try to use the original cable or high-quality analogue with data support. Cheap cables "only for charging" will not allow you to activate the modem modem, and the computer will simply start charging the phone.
Connection problems and their solution
Despite the reliability of the system, users sometimes face a situation where other devices can not connect to the created network or the connection is there, but the Internet does not work. Most often the problem lies in the wrong frequency range. If an old device tries to connect to a 5 GHz network, it may simply not see it. Switching to 2.4 GHz in the access point settings usually solves this problem.
Another common cause is conflict. IP-In this case, it helps to simply restart the communication module: turn on and off Flight Mode or just restart the smartphone. It is also worth checking whether the antivirus or firewall has a ban on incoming connections for system processes.
If the internet on the connected device is slow, check the cellular signal level on the Redmi 8 itself. In access point mode, the phone is more intense than in normal use, and with a weak signal (1-2 division), the speed can drop to a minimum.
⚠️ Warning: Long-term access point operation with poor cellular signal causes a strong heating of the case. If the phone gets hot, remove the protective case and put it on a hard surface for better heat sink to avoid trottling the processor.
Impact on battery and optimization
Modem mode is one of the most energy-intensive smartphone scenarios. The radio module is constantly on receiving and transmitting large amounts of data, which quickly consumes the battery of the Xiaomi Redmi 8. Although the capacity of 5000 mAh allows you to withstand several hours of active distribution, it is recommended to monitor the level of charge, especially if you are away from the outlet.
To minimize energy consumption, turn off unused functions: turn down the screen brightness, turn off geolocation and Bluetooth (if they are not used for distribution), close background applications. Also, limit the maximum number of users connected to the access point settings - the fewer clients, the less the load on the processor and radio part.
If you plan to use your phone as a fixed router for a long time, you better connect it to the power source. However, watch the temperature: simultaneous charging and active data transfer can lead to overheating, in such conditions, it is better to remove the dense protective case and not put the phone on soft surfaces that block the heat sink.
💡
The optimal balance between speed and power consumption is achieved by using the 2.4 GHz band and limiting the number of connected devices to 3-4 pieces.
Understanding the hotspot’s principles allows you to turn your smartphone into a full-fledged mobile office, and setting up security and traffic settings correctly ensures that you’re always online without worrying about data security or unexpected communication costs.
