How to set up an access point on Xiaomi

Modern smartphones have long ceased to be just devices for calls, becoming full-fledged portable entertainment centers and work tools. Owners of Xiaomi, Redmi and POCO devices often face the need to quickly provide access to the network to other gadgets, whether it is a colleague’s laptop or a child’s tablet. The function of the access point in the shell of MIUI and HyperOS is implemented as conveniently as possible, but hidden settings can confuse the inexperienced user.

In this article, we will take a look at all the aspects of building a Wi-Fi network based on your smartphone, how to change your default password, choose the optimal frequency for stable operation, and what to do if devices can’t see the network, and the right configuration of these parameters directly affects the data rate and battery life of your device.

Sometimes standard methods don't work because of software failures or carrier-specific settings. We'll look at not only the basic algorithm of actions, but also advanced problem-solving methods that will help you stay online in any situation. A deep understanding of how mobile hotspot works will allow you to effectively manage traffic and connected devices.

Basic settings through the settings menu

The easiest and most reliable way to activate modem modem is to use the system's regular menu. First, you need to go to the Settings section, which is usually represented by the gear icon on the home screen or in the notification curtain. In the list that opens, look for the Wi-Fi Access Point, which is often in the group of connection settings or wireless networks.

Once you go to this section, you'll see a switch that allows you to activate or deactivate the function. However, before you turn on, it's advisable to configure security settings. Click on your network name or the Access Point Settings button to change the device name (SSID) and set a strong password. Using WPA2 or WPA3 encryption protocol ensures that unauthorized persons will not be able to connect to your traffic without your knowledge.

⚠️ Note: Do not use simple combinations of numbers as a password, as they are easy to pick up with automatic programs.

You can also limit the number of devices you can connect to, which can help control traffic, so you can set a limit of, say, 5 or 10 customers, and then you can block new connections, and this is especially true when you use packets with limited data.

Selection of frequency range and Wi-Fi standard

One of the key features of modern Xiaomi smartphones is support for two frequency ranges: 2.4 GHz and 5 GHz. By default, the system can choose the range automatically, but to achieve maximum performance, it is better to adjust this parameter manually. The 2.4 GHz range has a longer range and better penetrates walls, but it is often overloaded with neighboring routers and household appliances.

If you want high data rates for streaming video or games, it is recommended to switch to 5 GHz. To do this, in the access point menu, find the frequency range and select the appropriate value. It is worth considering that older devices may not support this standard and simply will not see your network, in which case you will have to go back to a more compatible but slow range.

You can also choose Wi-Fi in advanced settings. The new models support Wi-Fi 6, which provides not only high speeds but also lower power consumption for multiple connections. If you distribute the Internet on a modern laptop or flagship smartphone, using the latest standard will give a tangible increase in performance.

Managing Connected Devices and Limits

Controlling who uses your Internet is a critical aspect of security and cost savings. MIUI A convenient list of connected customers is implemented, where they are displayed MAC-Addresses and device names: You can see in real time who is consuming your traffic, and if necessary, block unwanted users with a single click.

To fine-tune it, you can set a traffic limit. You can set a data limit, and then the access point will automatically shut down, and you can avoid unexpected communication bills if you accidentally leave the distribution on for a long time. You can set it up in Traffic Limit or Data Limit.

And then there's the whitelist feature, which allows you to only allow pre-approved devices to connect, which is the maximum level of security that even if you know the password, you can't get a third party to log in. MAC-Addresses of trusted gadgets and make them in the appropriate list in the settings.

Regularly checking the connection list helps you detect anomalies in traffic consumption. If you notice a device you are not familiar with, immediately change the password of the access point. This action will break all current connections and require re-entering the key on your personal gadgets.

Distribution of Internet via USB and Bluetooth

While Wi-Fi is the most popular way to distribute, in some situations it is more appropriate to use a wired connection or Bluetooth. USB-The modem provides the most stable connection with minimal delays, which is ideal for stationary work behind a laptop.In addition, with this connection, the smartphone simultaneously charges from the computer, which solves the problem of fast battery discharge.

For activation USB-In the modem, connect the phone to the computer with a cable and go to the access point menu. USB-The system will automatically install the required network adapter drivers. If the computer can't see the network, try replacing the cable with the original or better cable, since cheap wires often only support charging.

A Bluetooth modem is an option for emergencies where you need to transfer a small amount of text or data, and the Wi-Fi module is damaged or busy. The transfer speed is much lower here, and the setting requires pairing devices. However, the power consumption in this mode is minimal, which can be a decisive factor in a critical situation.

⚠️ Attention: When in use USB-The antivirus modem on your computer may perceive a new network connection as potentially dangerous. USB "Only Charge or Transfer Files before activating the modem if the automatic determination fails.

Advanced settings and hidden functions

The MIUI shell hides a few useful features for power users, one of which is the ability to change the timeout of the shutdown. By default, the access point turns off after 10 minutes of inactivity to save charge. In the engineering menu or through special applications, you can increase this interval or turn off auto-turning altogether.

Also, you should pay attention to the APN settings (Internet access points). If the Internet on connected devices is unstable or pages are partially loaded, the problem may be in the operator's settings. Go to Mobile Network → Access Points (APN) and make sure that the correct profile of your operator is selected. Sometimes it helps to create a new access point with manually entering parameters obtained on the operator's website.

For those who like to experiment, there is a possibility of changing hidden parameters through the engineering menu. By entering special code in the dialer, you can access the Wi-Fi signal power settings of the module. However, changing these parameters without accurately understanding the consequences can lead to unstable operation of the communication module or its complete failure, so it is recommended to proceed with extreme caution.

Solving common problems and errors

Despite the stability of the system, users may encounter a situation where the access point is turned on, but the Internet is not working, or devices can not see the network. Often the reason lies in a failure of the network stack. The first thing you try to turn on and off the flight mode (air mode), this action will restart all the radio modules of the smartphone and update the registration in the operator's network.

If the problem persists, check the date and time settings. Incorrect system time can cause security certificate errors, which can cause the system to fail. HTTPS-Sites will not open on connected devices. Set up automatic time synchronization over the network to eliminate this error.

In rare cases, network resets help. Note that this action will remove stored Wi-Fi passwords and Bluetooth pair settings, but often returns the modules to work. Path to reset: Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth.

💡

The most common cause of access point problems is not phone settings, but a weak signal from the mobile network or a lock on the distribution from the operator.
