Modern smartphones of the Xiaomi brand and its sub-brand Poco have become universal tools for work and entertainment, allowing you to stay online anywhere in the world. Often there is a situation when a laptop or tablet requires a connection to the global network, and the only available source is mobile traffic of your device. Owners of Poco F5, X5, X6 and other current gadgets may encounter some features of the shell MIUI or HyperOS, which hide the advanced modem settings.
Turning on the router mode is not a complicated process, but standard system algorithms sometimes block the connection of other devices or quickly land the battery. The correct configuration of the access point allows you not only to share traffic, but also to optimize power consumption, and improve data speed by choosing the right frequency range. In this article, we will discuss in detail all the nuances of the configuration, from basic inclusion to hidden engineering menus.
Before we get into the technical details, it’s worth noting that the menu interface may vary slightly depending on the firmware version. However, the logic of the system remains the same for the entire Xiaomi ecosystem. We’ll look at both standard methods and solutions for cases where the standard handout does not work or works unstable.
Basic activation of the access point through settings
The most obvious and common way to start modem modem modem is in the system menu. The user needs to lower the notification curtain and find the Access Point or Wi-Fi icon (depending on the version of the interface). However, to fully configure the security settings and the network name, it is better to go to the deep menu of the system through Settings → Wi-Fi Access Point.
Here you'll see a status switch, as well as a list of connected devices. At the top of the screen, the network name and default password are usually displayed. Changing the password is the first thing you recommend doing immediately after you buy a smartphone to prevent unauthorized access to your traffic.
In the same section available QR-This is especially useful if you need to connect a laptop or tablet that has a camera but doesn't have a physical keyboard to type a long password. Simply scan the code with another device’s camera and the connection will be established automatically without manual data entry.
⚠️ Warning: Do not use simple passwords like "12345678" or date of birth. Attackers can pick them up in seconds and use your connection to illegal activities, which will lead to blocking. SIM-card-holder.
The interface for setting up the access point in MIUI 14 and HyperOS has become more informative, now it displays not only the number of connected gadgets, but also the amount of data transferred per current session, which helps to control traffic consumption if you do not have an unlimited tariff plan.
Advanced setting: 5 GHz frequency and safety standards
For owners of modern models such as the Poco F5 Pro or Poco X6 Pro, the choice of frequency range is critical. By default, the system often sets the 2.4 GHz band, which has greater range, but is significantly inferior in speed and is subject to interference from household appliances. Switching to 5 GHz allows you to achieve the maximum speeds supported by your tariff.
To change this setting, you need to go to the Setting up Wi-Fi hotspot menu. → Frequency range. You can choose 5GHz here, preferably, which will force your smartphone to broadcast the network in a faster range. However, it's worth remembering that older devices may not see the network because they don't physically support this standard.
Another important aspect is the security protocol. In modern versions of Android and shells, Xiaomi recommends using WPA3-Personal or mixed WPA2/WPA3 mode. The older WPA2 standard is still relevant, but less protected from hacking. If you have very old gadgets that don't connect, you may have to temporarily reduce the level of protection to WPA2.
💡
Use the 5GHz band only in close proximity to your smartphone. At a distance of more than 10 meters, the signal can become unstable, especially if there are walls between devices.
In some cases, when the frequency changes, the devices may stop seeing the network, which can be done by rebooting the Wi-Fi module or completely resetting the network settings on the plug-in, and also check if the power saving mode on the Poco itself is on, which can limit the transmitter power.
Use of the USB-modems and Bluetooth panoramas
It's not always convenient to use a wireless connection, especially if you want to have a stable ping in games or a maximum download speed. USB-This method allows you to broadcast the Internet from phone to computer via cable, while charging your smartphone, which solves the problem of fast battery discharge.
To activate this mode, connect your smartphone to your PC with a cable. Then go to Settings → Wi-Fi hotspot → USB-The switch will only be active if there is a physical connection, the computer will recognize the device as a new network card and automatically install the required drivers.
An alternative, but less popular, method is a Bluetooth modem, which is activated in the same settings menu, and the data transfer speed is much lower than on Wi-Fi or USB, and rarely exceeds 1-2 Mbps. However, this method consumes minimal energy and can be useful in emergency situations when you need to send a text message or light mail.
☑️ Pre-insertion check USB-modem
It is important to note that when using a wired connection, speed can be limited by the bandwidth of the cable.Use original or certified Xiaomi cables to get the declared speed and safe charging current.
Hidden functions and engineering menu
The MIUI shell is famous for its hidden features, available through special codes. One useful tool is the engineering menu, which allows you to fine-tune the parameters of the radio module. To enter it, you use the code ##4636## typed in the Phone application.
Once you enter the code, you'll open a test menu, select Phone Information, and you'll find the network type you prefer, and while direct access point control is limited, you can force the phone to LTE Only or 5G Only, which can sometimes help stabilize the connection when the base station signal is bad.
Codeset: ##4636##
Phone Information → Set Preferred Network TypeThere is also a separate Wi-Fi menu available through ADB commands or special apps from GetApps, but it requires root rights. Without superuser rights, the options are limited to standard settings, which, however, cover 95% of the needs of the average user.
Is it dangerous to change the settings in the engineering menu?
Be careful when using third-party apps that promise to “boost the signal.” Often they simply reset the connection to the base station, forcing the phone to look for a new tower, which creates the illusion of improvement, but in practice only increases battery consumption.
Traffic Limitation and Management of Connected Devices
The Internet can quickly run out of your data packet if you don't set limits. The Xiaomi and Poco hotspot settings have a Traffic Limit function. Going to Settings → Access Point → Traffic Limit, you can set a limit value, such as 1 GB or 5 GB.
When the limit is exhausted, the distribution of the Internet will automatically shut down, which saves from unpleasant surprises in the form of bills for additional megabytes, and also allows you to adjust the period for which the limit is valid (monthly, daily or once).
In the Connected Devices section, you can see a list of all the gadgets that are using your Internet right now. MAC-If you notice a device with an unfamiliar name, lock it immediately and change the password.
| Parameter | Description | Recommended value |
|---|---|---|
| Frequency range | Choice between 2.4 GHz and 5 GHz | 5 GHz (for speed) |
| Security | encryption protocol | WPA2-PSK / WPA3 |
| Device limit | Maximum number of clients | 3-5 devices |
| Time out | Disconnection in the absence of customers | 10 minutes. |
⚠️ Attention: Setting the limit of connected devices to "1" is useful if you only distribute the Internet to your laptop.This will prevent other people's gadgets from connecting, even if they know the password until you remove the restriction.
Solving the Problem: Why the Distribution Is Not Working
Sometimes users are faced with a situation where the access point is turned on, but the Internet on connected devices does not work. The most common reason is the lack of mobile Internet on the smartphone itself.
The second common problem is conflict. IP-addresses or errors DHCP. In this case, a simple but effective method helps: turn on Flight Mode for 10 seconds, and then turn it off. This will restart all network modules. SIM-card ban on the use of tethering (distribution) by the operator.
If the problem persists, try resetting the network settings.This action will delete stored Wi-Fi passwords and Bluetooth settings, but often resolve deep software conflicts.The path to reset: Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth.
💡
If the internet does not work on a connected device, 80% of the time the problem is solved by switching the frequency range from 5 GHz to 2.4 GHz on the receiving device.
In rare cases, the culprit is an antivirus or firewall installed on your smartphone, try temporarily disabling third-party security apps and checking the network.
Effect of Distribution on Battery and Overheating
Active Wi-Fi distribution is one of the most energy-intensive processes for a smartphone. The communication module runs at maximum power, which leads to rapid discharge and heating of the case. Owners of Poco models with a plastic case can notice heating at the top of the device.
To minimize battery damage, it is recommended to use the Time Out function, in the settings of the access point, you can set an automatic shutdown if no one is connected to the network for 1, 5 or 10 minutes, this will prevent the module from running in vain.
If you plan a long session of handing out, for example, to work a laptop in a cafe, it is better to connect the smartphone to the charger. However, watch the temperature: the combination of fast charging and active Wi-Fi distribution can cause thermal trottling, which will artificially reduce the speed of the processor and modem.
Use of the USB-modem in conjunction with charging is the most gentle mode for the battery, since it eliminates energy loss for radio waves. In this case, the smartphone warms much less, and the battery even charges during operation.
