Modern smartphones of the brand Xiaomi and their sub-brands Redmi Mobile phones have long ceased to be mere calling devices, becoming powerful tools for work and entertainment. One of the most sought-after features for many users remains the ability to turn the device into a fully-fledged mobile router. This is especially useful when landline internet is down and a laptop or tablet urgently needs internet access.
The process of activating modem mode on devices with a shell MIUI or new HyperOS The interface may differ from standard Android, which often raises questions among owners. The settings interface has been redesigned to save battery life and improve user experience, but the basic principles remain the same. In this article, we'll cover all the nuances of creating a wireless network in detail.
You'll learn not only how to quickly enable a hotspot but also how to configure its settings for maximum security and speed. We'll cover frequency selection, traffic limits, and troubleshooting common errors users encounter when trying to connect to other devices.
Basic access point setup
To get started, go to your device's main settings menu. Find the section usually labeled "Wi-Fi Hotspot" or "Personal Hotspot." The path to it may vary slightly depending on the firmware version, but the logic remains consistent across the entire ecosystem. Xiaomi.
Once you enter the menu, you'll need to activate the power slider. The system will automatically prompt you to select a standard. Wi-Fi, which will be used to broadcast the signal. By default, the 2.4 GHz band is most often set, which provides good compatibility with older devices, but does not always provide maximum speed.
It's important to set a strong password right away to prevent unauthorized access to your traffic. You can also change the network name (SSID) in the access point settings menu, making it recognizable among surrounding signals. Remember that strong passwords protect your personal data from interception.
- 📱 Open Settings and select Wi-Fi Hotspot.
- 🔐 Create a complex password of letters and numbers to protect your channel.
- 📡 Select a security standard WPA2-PSK for better protection.
- 📝 Change the network name to something unique to avoid confusion in the list of available networks.
Using the Quick Menu and Widgets
It's not always convenient to delve into deep settings menus every time, especially if you need to share your internet connection urgently. MIUI Offers convenient widgets and controls that allow you to activate tethering mode with a single click. This significantly speeds up the process and saves the user time in critical situations.
To access quick settings, simply swipe down to open the notification shade. Among the many icons, look for the symbol resembling a chain or antenna. If you don't see it on the first screen, swipe right or tap the edit button to add it to the panel.
Another option is to use the "Hot Spot" widget on your home screen. You can add it through the widget menu by long-pressing an empty space on the screen. This allows you to monitor the number of connected devices and the amount of data used directly from the home screen, without having to go into settings.
- ⚡ Swipe down from the top edge of the screen to open the Control Center.
- 🔍 Find the "Access Point" icon and tap on it to activate it.
- 🖥 Add a widget to your desktop for quick access to statistics.
- ⏱ Use the widget to instantly disable distribution without entering the menu.
Setting up frequency and safety standards
One of the key features of setting up an access point on Redmi is the ability to select a frequency range. In the access point settings menu, often hidden under the "Access Point Settings" button, you can switch from 2.4 GHz to 5 GHz. This is critical for modern devices that support the standard. 802.11ac or ax.
The 5 GHz band offers significantly higher data transfer speeds, which is useful when watching high-definition video or downloading large files to a connected laptop. However, it has a significant drawback: a shorter range and poorer wall penetration compared to 2.4 GHz.
⚠️ Attention: Some older laptop and tablet models may not detect the network if it's operating in the 5 GHz band. If your device can't find the access point, try switching to the 2.4 GHz band.
The broadcast channel is also configured here. In automatic mode, the system automatically selects the least congested channel, but in dense urban areas, it sometimes makes sense to manually select a specific number. This helps avoid interference from neighboring routers and stabilize the connection.
☑️ Check security settings
The table below compares the main characteristics of the two frequency ranges available for tuning:
| Parameter | 2.4 GHz | 5 GHz |
|---|---|---|
| Maximum speed | Up to 150-300 Mbps | Up to 866 Mbps and higher |
| Range | High (up to 50 m) | Medium (up to 20-30 m) |
| Permeability of walls | Good | Low |
| Compatibility | Universal | Only modern devices |
Traffic limitation and connection control
Mobile internet often has limits, so it's important to monitor your data usage. In your hotspot settings Xiaomi There's a "Traffic Limit" feature. You can set a limit in megabytes or gigabytes, after which data sharing will automatically stop.
This prevents unexpected charges or speed reductions from your telecom provider. The system also allows you to see a list of all currently connected devices. You can monitor in real time who is using your network and block unwanted users if necessary.
Hidden limit settings
In some versions of MIUI, you can set not only a general limit, but also a limit for each device separately. However, this feature is not available in all regions and depends on the firmware version.
The "Whitelist" feature allows connections only to pre-defined devices based on their MAC addresses. This is the most secure method of protection, as even with the password, an unauthorized person won't be able to connect unless they're on the allowed list.
- 📉 Set a daily or monthly traffic limit in the hotspot settings.
- 👁 Check the list of connected devices through the control menu.
- 🚫 Block unknown devices with one click in the client list.
- ✅ Activate the whitelist to allow only trusted devices.
Troubleshooting connection and visibility issues
Sometimes it happens that the access point is turned on, but other devices don't see it or can't connect. Power saving is often the primary reason. HyperOS It can aggressively limit background processes, considering the access point as an unnecessary load if the smartphone screen is turned off.
To fix this, go to battery settings and find the app responsible for the hotspot (often called "HotSpot Services" or something similar). Allow it to run in the background and disable power saving. This will ensure stable operation even when the screen is off.
⚠️ Attention: Carrier interfaces and plan types may vary. Before actively sharing, make sure your plan doesn't block using your phone as a router or require a separate fee for this service.
Another common issue is an IP address conflict or a full network settings cache. In this case, resetting the network settings or simply restarting the smartphone can help. It's also worth checking that airplane mode isn't enabled, as it can block Wi-Fi, even if it appears active.
In rare cases, the issue lies with the hardware or drivers after a system update. If all else fails, reset all network settings to factory defaults, but keep in mind that this will delete saved passwords for other Wi-Fi networks.
Sharing via USB and Bluetooth
It is not always convenient or safe to use wireless data transmission. Protocol USB It allows you to not only transfer data but also charge your smartphone, which is crucial for long-term use. Simply connect your phone to your computer via a cable and select the appropriate mode in the "USB Modem" menu.
The computer automatically detects a new network connection. This is ideal for desktop workstations where connection stability and minimal latency (ping) are essential. Speed in this mode is limited only by mobile internet speed and cable bandwidth.
A Bluetooth modem is an option for very old devices or specific situations where the Wi-Fi module is faulty. Speeds will be significantly lower, and setup is more complicated, as it requires pairing the devices. However, it works as a backup when other options are unavailable.
- 🔌 Connect your smartphone to your PC using a cable and select the "USB modem" mode.
- 🔋 Use a wired connection to charge the battery simultaneously.
- 📉 Use a Bluetooth modem only as a backup option due to low speed.
- ⚙ Bluetooth requires mandatory pairing of devices before transmitting internet.
Why doesn't my laptop detect the Xiaomi hotspot?
Most often, the problem stems from incompatible security standards or frequency bands. Try changing the encryption protocol from WPA3 to WPA2 in your phone's hotspot settings, and switching the frequency band from 5 GHz to 2.4 GHz. Also, check that the network name (SSID) isn't hidden in the privacy settings.
Does your phone's battery drain significantly when using Wi-Fi?
Yes, hotspot mode is one of the most power-hungry processes. The Wi-Fi module operates at maximum power, constantly transmitting and receiving data. It's recommended to keep your phone charged or use a power bank if you plan to share the internet for extended periods.
Is it possible to share Wi-Fi if your phone doesn't have a SIM card?
No, to share mobile data, you need an active SIM card with a data plan. However, if your phone is connected to a Wi-Fi network, some models can rebroadcast this signal (repeater mode), but this feature is often blocked on stock Xiaomi firmware.
