In today's world, mobile internet has become an integral part of the digital ecosystem, and situations often arise when a desktop computer or laptop requires internet access but a wired connection is not available. Smartphone owners Xiaomi And Redmi Users can easily turn their gadget into a full-fledged router using the built-in access point function. This solution is especially useful for remote work, travel, or when a home provider is temporarily unavailable, allowing you to quickly set up a local network.
The setup process on devices with a shell MIUI or HyperOS It's extremely simplified and doesn't require any third-party software. However, despite its apparent simplicity, there are many nuances that affect connection stability and data transfer speed. Correct configuration It allows you not only to connect, but also to ensure secure data exchange, minimizing the risk of traffic interception by intruders.
In this article, we'll detail the steps for activating tethering mode, discuss choosing the optimal frequency band, and examine common mistakes users encounter. You'll learn how to extend your smartphone's battery life when actively tethering and which hidden menu settings might be useful for advanced users.
Activating hotspot in MIUI settings
The first step to setting up a wireless connection is to enter the system network management menu. On smartphones Xiaomi This process is standardized, but the layout of the elements may vary slightly depending on the firmware version. You need to open the application Settings and find the section responsible for connecting to the outside world.
Next you should select the item Wi-Fi hotspot, which is usually located at the top of the list or inside a tab Connection and sharingThis is where the switch that activates router mode is located. Once activated, the phone will begin broadcasting a signal that can be detected by any Wi-Fi receiver.
- 📱 Open the notification shade and press and hold the hotspot icon to quickly access the menu.
- ⚙️ In the classic menu, the path looks like this:
Settings→Wi-Fi hotspot. - 🔒 Check the password you set immediately to avoid unauthorized connections.
⚠️ Note: When you first enable the system, you may be asked to confirm whether you want to use mobile data for tethering. Make sure you have a data plan with sufficient gigabytes, otherwise you may be unpleasantly surprised by the charges.
It's important to set up a network name (SSID) right away to easily identify your phone among the many other signals in an apartment building. By default, the device uses the smartphone model, but it's best to set a unique name, such as Home_Xiaomi_5GThis will make it easier to find the device on your computer and increase security.
Setting up security and selecting a frequency range
A critical step is choosing the encryption protocol and frequency range. In the access point menu Xiaomi A band setting is available, allowing you to choose between 2.4 GHz and 5 GHz. The choice depends on the standards supported by your computer and environmental conditions.
Range 2.4 GHz has greater penetration power and is compatible with all devices, even very old ones, but it is often overloaded with signals from neighboring routers and household appliances. The range 5 GHz It provides significantly higher data transfer rates and is less susceptible to interference, but its range is shorter and older network cards may simply not see it.
In the security section, the protocol must be selected. WPA2-Personal or WPA3, if available. Using an open network or outdated encryption WEP makes your data vulnerable. Your password should be complex, containing mixed-case letters and numbers to prevent brute-force attacks.
| Parameter | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Transfer speed | Up to 150-300 Mbps | Up to 400-800+ Mbps |
| Range of action | High (up to 30-40 m) | Medium (up to 15-20 m) |
| Penetration ability | Good (through walls) | Low (walls muffle the signal) |
| Compatibility | 100% of devices | Only modern adapters |
You can also set a traffic limit or access point operating time in this menu. Function Auto power off This is useful if you forget to turn off tethering when your computer no longer needs the internet. This helps conserve battery life and prevents background data usage.
Connecting a computer to a smartphone's network
Once the access point is on Xiaomi activated and configured, you need to pair it with your computer. On a PC with an operating system Windows You need to click on the Wi-Fi icon in the tray (lower right corner of the screen) and wait for the list of available networks to appear.
Find the name you set earlier or the default phone model name in the list. Click the button ConnectThe system will prompt you to enter a security key. Enter the password you set in your phone settings, making sure to be capitalized. If the information is entered correctly, the "Connected" status will appear after a few seconds.
- 💻 Make sure your computer's Wi-Fi is turned on (there's often a physical switch or keyboard shortcut
Fn + F2). - 🔍 If the network is not displayed, try moving your phone closer to the computer or rebooting the wireless module.
- 🔄 If you experience connection errors, use the "Forget network" function and try entering the password again.
In some cases, especially on corporate laptops, security policies may block connections to mobile hotspots. If you see the network but can't connect, check your firewall or antivirus settings on your PC. The network may be marked as "Public," which limits some file sharing features, but internet access should still work.
☑️ Connection checklist
Troubleshooting visibility and connectivity issues
A situation where the computer does not see the access point XiaomiThis is quite common and can be caused by a variety of reasons. One of the most common is incompatibility with security standards or frequency ranges, as discussed above. If the laptop is old, it will physically be unable to detect the 5 GHz network.
Another possible cause is a hidden SSID. Your phone's settings include an option called "Hide Device," which makes the network invisible to public searches. To connect in this case, you'll need to create a new connection manually in Windows, entering the network name and encryption type yourself.
⚠️ Note: The MIUI interface is constantly being updated. If you don't find the options described above, use the settings search (the magnifying glass at the top of the screen) and search for "Access Point" or "Tethering."
Problems can also be caused by an overcrowded DHCP client list. If many devices have previously connected to your phone, some may be stuck in the modem's memory. In this case, a simple reset of the hotspot function helps: turn off the slider, wait 5 seconds, and turn it back on.
Hidden Engineer Settings
In the Android engineering menu (accessible via dialing ##4636##) You can change the Wi-Fi signal strength, but you should do this with caution, as this may lead to overheating of the module or unstable operation of the system.
Optimizing power consumption and speed
Sharing the internet is a power-intensive process that quickly drains your smartphone's battery. Wi-Fi modem This creates a constant load on the processor and radio module, which leads to heating of the casing. To minimize risks, it is recommended to keep the phone connected to a charger during active use.
To improve data transfer speed, close background apps on your phone that may consume data (cloud syncs, game updates, streaming services). It's also a good idea to turn off Bluetooth when not in use, as it operates in the same 2.4 GHz frequency range and can cause interference.
There's a myth that turning on airplane mode and then switching to Wi-Fi only will help share the internet. This is incorrect: in airplane mode, the cellular radio is disabled, and the phone has no internet connection to share. Mobile data must be active.
Alternative distribution methods: USB and Bluetooth
If your wireless connection is unstable or you need maximum speed with minimal latency, consider a wired option. Connecting via USB cable not only allows for high-speed data transfer but also charges your phone simultaneously, reducing power consumption.
To activate the USB modem, connect your smartphone to your computer with a cable, then select the item in the access point menu USB modemThe computer will automatically detect the new network connection. This method is ideal for desktop PCs without a Wi-Fi adapter.
- 🔌 The USB cable must be of high quality and support data transfer, not just charging.
- 🛡️ A wired connection is more secure because it eliminates the possibility of signal interception over the air.
- ⚡ USB 3.0 speeds can exceed even the 5 GHz band.
A Bluetooth modem is the least efficient option and should only be used in extreme cases when other methods are unavailable. Speeds rarely exceed 1-2 Mbps, which is sufficient only for text messaging or loading light pages, but not for working with heavy content.
Why does my computer say "No Internet access" even though Wi-Fi is connected?
Most often, the problem lies in DNS settings or a lack of mobile data on the SIM card. Try entering Google's DNS servers (8.8.8.8 and 8.8.4.4) in the IPv4 properties on your computer. Also, check whether your account is full or your gigabyte limit has been reached.
Is it possible to share Wi-Fi if the phone is connected to a Wi-Fi router?
On most modern smartphones Xiaomi With Android 10 and above, the repeater (amplifier) feature works: the phone receives Wi-Fi and broadcasts it further. However, on older models or in some regions, this feature may be blocked by the manufacturer. In this case, the phone will offer to use mobile data instead of extending the network.
How many devices can be connected simultaneously?
Technically the shell MIUI Allows you to connect up to 10 devices simultaneously. However, the actual number depends on the processor load and the phone's RAM. If more than 3-4 active users are connected, the speed on each device will noticeably drop, and the phone may become very hot.
