In today's digital world, situations where a laptop is left without internet access, and all you have at hand is a smartphone with mobile data, are common. XiaomiAs a market leader, MIUI offers users extensive personal networking capabilities. This feature, known as "Access Point" or "hotspot," allows you to turn your mobile device into a fully-fledged router.
Configuration process in the shell MIUI or HyperOS may differ from standard Android, which sometimes raises questions among users. We'll cover not only the basic activation steps but also the subtleties that will help ensure a stable connection and maximum data transfer speed. You don't need to be a tech expert to complete these steps.
Using your smartphone as a modem is a temporary solution, but it requires proper security and power management settings. Incorrect configuration can lead to rapid battery drain or slow page loading on the connected computer. Let's break it down in detail.
Preparing the device and checking network settings
Before you start creating a hotspot, you need to make sure that your smartphone Xiaomi Ready to use as a modem. The first step should always be checking your mobile internet status. Make sure your SIM card is active, your data plan allows data sharing, and the icon in the corner of the screen is lit. 4G or 5G.
It's also worth paying attention to the signal strength. If the network is poor at your current location, your Wi-Fi connection will also be unstable. In some cases, it might be worth moving closer to a window or to an open area to improve the connection to the carrier's base station.
⚠️ Please note: Mobile operators may limit the speed or data volume when sharing internet with other devices. Check your plan terms in the operator's app to avoid unexpected blocks or charges.
It's also important to check whether "Data Saver" or "Power Saver" modes are enabled on your phone, as they can interfere with the hotspot's operation. These features often aggressively limit background processes and data transfer, which is critical for maintaining a stable connection to your laptop.
Step-by-step activation of access point in MIUI and HyperOS
Settings interface in phones Xiaomi While it's highly customizable, the modem activation logic remains the same. To get started, swipe down from the top of the notification shade and find the "Tethering" icon. This is the fastest way to activate the feature.
If you prefer deeper control over your settings, head to the settings menu. The path typically looks like this: Settings → Wi-Fi HotspotIn some firmware versions, this item may be located under the "Connection and Sharing" section. Here you'll see a switch for the module's status.
☑️ Check before switching on
Once the slider is activated, the smartphone will begin broadcasting a signal. By default, the network may be open or have a default name, so it's crucial to immediately configure security. Avoid leaving your network open in public places, as this creates the risk of data interception.
In the access point settings menu, you can change the network name (SSID) and set a strong password. It is recommended to use encryption. WPA2-Personal, as it provides a balance between compatibility with older devices and the level of protection of transmitted data.
Connecting a laptop to the created network
After the phone Xiaomi started to emit a signal, you need to pair it with your laptop. On a computer running Windows Click on the Wi-Fi icon in the tray (usually on the screen) and find the name you set on your phone in the list of available networks.
Enter the password you set earlier. Please pay attention to the case of letters, as the security system is sensitive to these details. After successful authentication, Windows will confirm the connection, and the network status will change to "Connected, Secure."
| Parameter | Default value | Recommended value | Impact on work |
|---|---|---|---|
| Frequency range | 2.4 GHz | 5 GHz (if supported) | Signal speed and range |
| Security protocol | WPA2-Personal | WPA2/WPA3 | Data protection level |
| Max. number of devices | 10 | 1-3 | Speed stability |
| Shutdown timeout | 10 minutes | No restrictions | Autonomy of operation |
If your laptop isn't detecting the network, try refreshing the list of available connections or restarting the computer's Wi-Fi module. Sometimes, simply turning the wireless adapter off and on in Device Manager or using a hotkey helps.
What should I do if my laptop sees the network but doesn't connect?
Try forgetting the network on your laptop and reconnecting. Also, check if there's a MAC address restriction in your phone's hotspot settings. In rare cases, resetting the network settings in Windows with the netsh winsock reset command helps.
Frequency range adjustment and speed optimization
One of the key settings that affects performance is the choice of frequency band. In the access point settings Xiaomi You can choose between 2.4 GHz and 5 GHz. Range 2.4 GHz has better penetration ability, but is often overloaded with neighboring routers and devices.
Range 5 GHz Provides significantly higher data transfer rates and is less susceptible to interference, but has a shorter range. If your laptop is close to your phone, switching to 5 GHz makes sense for comfortable work with heavy content.
To change this setting, go to Access Point Settings → Access Point Configuration → AP Frequency BandSelect the desired option and save the changes. Your phone may reboot the Wi-Fi module, which will temporarily disconnect the connection.
⚠️ Note: Not all older laptops support the 5 GHz band. If your computer no longer sees the network after switching, revert back to 2.4 GHz.
It's also worth limiting the maximum number of connected users. If too many devices connect to your hotspot, the internet speed on each of them will drop to an unacceptable level. Ideally, keep this setting to 1-3 devices.
Sharing the Internet via USB and Bluetooth
If your wireless connection is unstable or you need maximum speed, you can use a wired connection. To do this, connect your phone Xiaomi Connect to your laptop via a USB cable. In the access point menu, select "USB tethering."
This method has several advantages: the phone is simultaneously charged by the laptop, which is critical for long-term use, and it also ensures a more stable connection without packet loss. The computer recognizes the device as a new network connection.
A Bluetooth option also exists, but it's significantly slower and only suitable for transferring small amounts of text information or using instant messaging apps. It's activated in the same hotspot settings menu but requires pairing the devices via the Bluetooth menu.
When using a USB modem, make sure that the necessary drivers are installed on your computer. Usually Windows 10 And Windows 11 They are found automatically, but in some cases it may be necessary to install proprietary software Mi PC Suite or ADB drivers.
Troubleshooting and optimization
Users often encounter a situation where they have internet access on their phone, but pages won't load on their laptop. This may be due to incorrect settings. DNSTry manually entering DNS servers (for example, Google's: 8.8.8.8) in the network connection properties on your laptop.
Another common problem is the hotspot turning off automatically. In the settings Xiaomi There's a "Turn off the hotspot" feature if no one is connected for a certain amount of time. Make sure this timer is set to "Never" or a longer period if you plan on a long session.
⚠️ Caution: When using Wi-Fi hotspots, your phone may become very hot. Avoid exposing your device to direct sunlight and remove any thick case for better heat dissipation to prevent processor throttling.
If your connection speed remains slow despite a strong signal, check the apps running on your phone. Background downloads of updates or photo syncing can be consuming your bandwidth. Close unnecessary apps using the task manager.
Security and control of connected devices
Controlling who is connected to your network is a crucial aspect of security. In the access point menu Xiaomi There's a "Connected Devices" section that displays all active clients. You can block an unknown device at any time.
Using a strong password is your first line of defense. Avoid simple combinations like "12345678" or your date of birth. A combination of mixed-case letters, numbers, and special characters, at least 10 characters long, is best.
Hiding the network name (SSID) is another measure that will make your access point invisible to passersby. However, to connect a laptop, you'll have to manually enter the network name the first time you pair it, as automatic detection won't detect it.
Change your access password regularly, especially if you've used a public hotspot. This will minimize the risk of data stored on other people's devices allowing someone to access your traffic in the future.
Is it possible to hide the network name (SSID) on Xiaomi?
Yes, there's a "Hide Device" option in the access point's advanced settings. When enabled, the network won't appear in the general list, and you'll need to manually enter the exact network name (SSID) on your laptop to connect.
Why doesn't my laptop detect my Xiaomi phone's hotspot?
Most often, the problem lies in the frequency range. If your phone uses the 5 GHz Wi-Fi band, but your laptop's network card is old and only supports 2.4 GHz, the devices won't see each other. Switch the frequency range in the access point settings.
Does your phone's battery drain significantly when using Wi-Fi?
Yes, hotspot mode is one of the most power-hungry modes. The Wi-Fi module operates at increased power, and the processor is constantly processing data packets. It's recommended to keep your phone charged while using tethering mode.
Is it possible to share Wi-Fi if VPN is enabled on the phone?
By default, Android and MIUI don't forward the VPN connection to a hotspot. For a laptop to work through a phone's VPN, root access and special apps are required, or a VPN client needs to be configured directly on the laptop.
How can I find out how much traffic my connected laptop has used?
It's difficult to track the traffic of each connected device in detail using MIUI's built-in tools. It's best to use traffic monitoring apps on your laptop or monitor usage through your mobile operator's app, which displays the total amount of data transferred.
Why does the speed drop when connecting a second device?
Mobile internet shares bandwidth among all clients. If one device starts downloading a large file, the other gets less bandwidth. The smartphone's processor power is also limited when encrypting traffic for multiple clients.
