The modern smartphone has long since ceased to be just a device for making calls and has become a fully-fledged control center for your digital life. When a fixed router is unavailable or your home ISP is down, Android gadgets become a real lifesaver. Brand devices Xiaomi, including the popular line Redmi, are equipped with a powerful wireless module that allows you to instantly turn your phone into a full-fledged access point Wi-Fi.
This feature is especially useful for laptops, tablets, and game consoles that don't have their own cellular module. The process of activating tethering mode in the shell MIUI or HyperOS The developers have simplified the interface as much as possible, but it hides a number of advanced settings. These allow you to optimize data transfer speeds and ensure connection security from unauthorized access by third parties.
Before we dive into the detailed steps, it's worth noting that the quality of your future connection directly depends on the cellular network signal strength in your location. If your smartphone screen displays 3G or E, then high data transfer speeds will be unavailable regardless of the phone's antenna power. For comfortable internet browsing, stable coverage is desirable. 4G or 5G.
Distributing traffic via a wireless interface drains the battery charge significantly faster than in normal standby mode. Energy consumption Increases due to the radio module constantly transmitting. Therefore, if you plan to use your phone as your primary router for an extended period, it is recommended to connect the device to a power source or external battery. Power Bank.
Activating the hotspot via the notification shade
The fastest way to launch tethering is to use the quick access panel. This is a standard procedure that doesn't require diving deep into the system settings menu. Simply unlock your device's screen and swipe down from the top edge of the display to open the control center.
In the list of shortcuts that opens, find the icon labeled "Access Point" or "Hotspot." In some firmware versions, this item may be labeled "Portable Hotspot." If you don't see the icon you need on the first page, swipe right to reveal the full list of available widgets.
⚠️ Note: When you first launch the system, you may be asked to confirm that you want to enable Bluetooth and geolocation modules, as they are used to determine the location and pair devices.
After tapping the icon, it will light up, indicating successful activation. Other devices can now detect your phone in the list of available networks. However, the default settings often have a default name that easily identifies your phone model, which isn't always safe in public places.
Deep configuration of network settings in the menu
To ensure maximum security and ease of use, you should change the default network settings. Go to the main menu and select Settings, then go to the item Wi-Fi hotspotHere you will find a full range of tools for customizing the connection.
The first thing that catches your eye is the ability to change the network name (SSID). The standard name often contains the phone model, for example, Redmi Note 10It's recommended to rename the network to something neutral or difficult to recognize to prevent others from trying to guess the password to your device.
Next, you need to set a strong password. The system suggests using encryption like WPA2 PSK, which currently offers the optimal balance between compatibility with older devices and security. Avoid using simple combinations of numbers; it's better to use a combination of letters and symbols.
- 📡 Frequency range: Choose 2.4 GHz for better compatibility with older laptops or 5.0 GHz for maximum data transfer speeds.
- 🔒 Hiding the network: Enable this option if you want the network to be visible only to those who know its exact name.
- ⏱️ Sleep timer: Set up your hotspot to turn off automatically if no one is connected to it for a certain period of time.
☑️ Configuring access point security
Frequency range selection and compatibility
One of the key parameters affecting the speed and stability of the connection is the choice of operating frequency. In the access point settings menu, Xiaomi A choice between the 2.4 GHz and 5 GHz bands is often offered. Understanding the differences between them is critical for proper configuration.
The 2.4 GHz band is the most common and compatible. It penetrates walls better, but is often overloaded with signals from neighboring routers and household appliances like microwaves. This can lead to unstable ping and reduced speeds in apartment buildings.
The 5 GHz band offers significantly higher throughput and is less susceptible to interference. However, its range is shorter and it penetrates obstacles less effectively. If you are in the same room as the receiving device, 5 GHz is the optimal choice.
⚠️ Note: Some older laptops and tablets may simply not see the network if it operates in the 5 GHz range, since their network cards do not physically support this standard.
In new versions of the shell HyperOS A "Smart Band Selection" feature has been added, which automatically switches frequencies depending on the connected device. This eliminates the need for users to manually reconfigure settings every time they change devices.
Technical nuances of ranges
The 2.4 GHz band has 13 channels, of which only 3 are non-overlapping (1, 6, 11). The 5 GHz band offers many more non-overlapping channels, reducing interference in densely populated areas.
Managing connected clients and limits
Controlling who uses your internet traffic is a crucial part of security. In the access point menu Xiaomi We've implemented functionality that allows you to see a list of all connected devices in real time. You can monitor their activity and block unwanted users if necessary.
You can set a limit on the number of connected devices. The default limit is usually 10 users, but you can lower it to 1-2 if you're sharing internet only with your laptop and tablet. This will prevent someone from hogging your network and consuming all your bandwidth.
The whitelist feature is also useful (Whitelist). If you activate this mode, only devices whose MAC addresses are added to the allowed list. All other connection attempts will be automatically rejected by the system, even if the attacker has the correct password.
| Parameter | Description | Recommended value |
|---|---|---|
| Max clients | Limit of simultaneous connections | 3-5 devices |
| Time-out | Time until auto-off | 10 minutes |
| Encryption | Data Protection Protocol | WPA2-Personal |
| Range | Operating frequency of the signal | 5 GHz (if supported) |
Saving traffic and optimizing battery
Using a smartphone as a router puts a heavy load on the hardware components. The processor and radio module operate in an enhanced mode, which leads to the case heating up and rapid battery drain. To minimize these effects, MIUI Special optimization tools are provided.
In the hotspot settings, you can find the "Data Saver" option. When enabled, the system will block background syncing and automatic app updates on connected devices when they're not actively being used. This helps conserve data usage if you don't have an unlimited data plan.
The standby time setting deserves special attention. The automatic hotspot shutdown feature helps conserve battery if you forget to turn off the hotspot after finishing your work. It's recommended to set the interval to 5 or 10 minutes to prevent your phone from running idle.
⚠️ Note: Menu interfaces and item names may vary slightly depending on the Android version and specific Redmi model. Always check your device's current settings.
It's also worth remembering that when actively sharing Wi-Fi, it's not recommended to run heavy games or navigation apps on the smartphone itself. This can cause processor overheating and throttling, resulting in a drop in internet speed for all connected clients.
Solving common connection problems
Despite a well-functioning system, users may encounter situations where devices cannot see the network or obtain an IP address. Most often, the problem stems from incompatible security protocols or a full network settings cache.
If your laptop says “Cannot connect to this network”, try changing the encryption type on your phone from WPA3 on WPA2Newer security standards sometimes don't work correctly with older network card drivers. A full factory reset of the access point also helps.
If the connected device has internet access but pages aren't loading, check your DNS settings. You can configure static DNS addresses on the receiving device, such as those from Google (8.8.8.8) or Cloudflare (1.1.1.1). This often solves problems with accessing websites.
- 🔄 Reboot: Simply turning the mobile internet off and on often solves the problem of a frozen module.
- 📶 Change channel: If there are many networks in the room, try manually changing the broadcast channel in the advanced settings.
- 📱 Network reset: As a last resort, you can reset the network settings in the phone menu, but this will delete saved Wi-Fi passwords.
Hidden codes for diagnostics
In the Android engineering menu (not available on all firmware versions), you can check the signal strength using the code ##4636##By selecting "Phone Information," you can see the RSSI signal level in dBm.
Alternative ways to distribute Internet
In addition to classic Wi-Fi, smartphones Xiaomi Other internet connection sharing options are available. A USB modem allows you to share internet with your computer via a cable, ensuring a stable connection without speed loss and saving your phone's battery since it charges from your PC.
A Bluetooth modem is another option, albeit significantly slower. It's suitable for transferring small amounts of data or for connecting older devices that don't support Wi-Fi. Speeds in this mode rarely exceed 1-2 Mbps, which is only sufficient for instant messaging apps.
To connect to Smart TVs or gaming consoles that do not have an on-screen keyboard for entering a password, it is convenient to use the function WPS (if supported by the client router) or a QR code. A QR code is generated on the phone screen in the access point menu. By scanning it, the guest will instantly connect to the network without manually entering characters.
How to connect via USB cable?
Connect your phone to your computer using a cable. Go to your hotspot settings and turn on the "USB tethering" switch. Your computer will automatically detect the new network connection. This method ensures minimal latency (ping) and no radio interference.
Why isn't 5 GHz sharing working?
Not all regions and not all device models support 5 GHz access points due to regulatory restrictions or chipset hardware. If the option is unavailable or grayed out, it means your device or firmware does not support this feature.
Is it possible to share Wi-Fi if it is already connected?
Yes, most modern smartphones Xiaomi They can simultaneously receive and broadcast Wi-Fi, acting as a repeater. However, in this mode, speed may be lower, and the battery will drain faster due to the double load on the radio module.
How do I find out who is connected to my network?
The "Wi-Fi Hotspot" -> "Connected Devices" menu displays a list of all active clients. It shows the device name, its MAC address, and the amount of data transferred. You can block any device directly from this list.
