Every user has experienced situations where their desktop computer or laptop is left without wireless internet, or their router suddenly stops working. In such moments, a smartphone, which can instantly transform into a fully-functional router, becomes a lifesaver. Devices from the brand Xiaomi and their sub-brands Redmi, MIUI shell (or new one HyperOS) which provides flexible tools for managing network connections.
Internet distribution via Wi-Fi hotspot A Wi-Fi modem isn't just a copy of a modem's functionality; it creates a fully-fledged local network where your PC accesses the global network via your phone's mobile data. This method is often more stable and faster than a Bluetooth modem, and much more convenient than searching for a USB cable when your laptop's battery is dead. However, to ensure the connection operates at maximum speed and doesn't drain your device's battery in just a couple of hours, it's important to properly configure the signal broadcast settings.
In this article, we'll detail the process of activating tethering mode on various Redmi models, explore the nuances of choosing a frequency band, and answer questions about data security. You'll learn how to avoid common connection errors and why your computer might not see the network, even though it appears correctly on other devices.
⚠️ Note: The settings menu interface in MIUI and HyperOS may vary slightly depending on the Android version and regional firmware. If you can't find the item described, use the settings search (magnifying glass at the top of the screen) and enter the keyword "Modem."
Preparing your Redmi smartphone for router mode
Before you start broadcasting a signal, you need to make sure that the internet source itself is working properly. First, check that the mobile network module is activated and that your carrier has network coverage. Without a stable signal 4G/LTE or 5G Creating an access point makes no sense, since the computer will only receive a local network without Internet access.
Traffic control is an important aspect. Many tariff plans have high-speed internet usage limits, after which the speed may be significantly reduced. When connecting a PC to a phone's hotspot, traffic is consumed significantly faster than when using a smartphone due to background Windows updates and heavy applications running. It is recommended to check the remaining gigabytes in your operator's application in advance.
Power consumption is also a consideration. Hotspot mode significantly impacts the device's processor and radio module, causing the device to heat up and drain quickly. If you plan to use it for extended periods, it's best to keep the phone connected to a charger or power bank to avoid unexpected network outages.
- 📱 Make sure mobile data is turned on and the button is not grayed out.
- 📡 Check the signal level in the status bar - it should be at least 2-3 divisions.
- 🔋 Charge your smartphone battery to at least 40-50% before starting distribution.
- 📉 Disable background synchronization of large files (photos, videos) during the session.
⚠️ Please note: Mobile operators may block or limit the speed of internet sharing with other devices (TTL filters). If the speed on your PC is significantly lower than on your phone, contact your carrier's support to clarify the terms of your plan.
Activating the access point in the system settings
The process of starting the modem mode in smartphones Redmi It's standardized, but has its own specific features depending on the operating system version. The classic route is through the main settings menu. You need to open the section usually called "Wi-Fi hotspot" or "Portable Wi-Fi modem."
Within this menu is a switch that activates broadcast mode. However, before enabling it, it's highly recommended to go to the access point settings subsection. Here, you can change the network name (SSID) to something more recognizable to avoid confusion with neighboring networks, and set a secure password.
Using the default system password is unsafe in public places, as it can be guessed or intercepted. Create a combination of letters and numbers at least 8 characters long. After saving the settings, you can activate the enable slider.
☑️ Pre-launch check
An alternative and faster way to activate it is to use the notification shade. Swipe down twice from the top to reveal all quick access tiles. Find the "Wi-Fi Hotspot" icon. If it's not on the first screen, swipe left or tap the edit tile button to add it to your active set.
Setting up frequency and safety standards
One of the key settings that affects compatibility and speed is the choice of frequency band. In the access point menu Redmi Two options are typically offered: 2.4 GHz and 5 GHz. Each has its own advantages and disadvantages that must be considered when connecting a computer.
Range 2.4 GHz is the most versatile. It provides good range and penetration through walls, which is useful if your phone is in one room and your PC in another. However, this range is often overloaded with signals from neighboring routers, microwave ovens, and Bluetooth devices, which can reduce actual speed.
Range 5 GHz Offers significantly higher data transfer speeds and is less susceptible to interference. It's an ideal choice for watching 4K video, playing online games, or downloading large files. However, it does have a significant drawback: shorter range and poorer penetration through obstacles. If there's a wall between the phone and the computer, the signal may drop out.
| Parameter | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Speed | Average (up to 150 Mbps) | High (up to 800+ Mbps) |
| Range | Big | Medium/Small |
| Penetration of walls | Good | Low |
| Workload | High (a lot of interference) | Low |
| Compatibility | Works on all PCs | Only modern adapters |
⚠️ Note: Older laptop models (manufactured before 2013-2014) and budget USB adapters may not support the 5 GHz standard. If your computer doesn't see the network after switching to 5 GHz, reset the setting to 2.4 GHz.
It is also recommended to select an encryption standard in the security settings. WPA2 PSK or WPA3, if your device supports it. This ensures that the data you transmit (passwords, correspondence, banking transactions) is protected from simple interception.
Connecting a computer to the Redmi network
Once the hotspot on your phone is activated, we move on to setting up your computer. The process of searching for a network on Windows 10/11 or macOS It's almost identical to connecting to a regular home router. You need to open the list of available wireless networks.
Find in the list the name (SSID) that you set earlier (or the standard model name of your Redmi). Click on it and press the "Connect" button. The system will ask you to enter a security key. Enter the password you set in your phone settings, making sure to be capitalized.
After successful authentication, the system will assign an IP address, and a connection icon will appear in the system tray (near the clock). If the status changes to "Connected, Secure," the internet connection should be working. Open your browser and try visiting any website to check.
⚠️ Note: If your computer says "Can't connect to this network," try selecting "Reset settings" in your phone's hotspot settings or simply turning your mobile internet off and on again, then restarting your hotspot.
Sometimes Windows may detect a network as "Public," which activates stricter firewall rules. This is usually fine for a home network, but if you plan to transfer files between devices or use a printer, you may need to change the network profile to "Private" in the corresponding Windows menu.
Using a USB modem as an alternative to Wi-Fi
If your wireless connection is unstable or the speed isn't working for you, connecting via a USB cable is a great solution. This method, known as USB modem, allows you to not only transmit Internet, but also charge your phone at the same time, which solves the problem of rapid discharge.
To implement this method, connect your phone and computer with a high-quality cable that supports data transfer (not all cables are suitable for this, some are only for charging). Then, in the access point menu on Redmi Select "USB modem" and activate it.
The computer will automatically recognize the new network device and install the necessary drivers. The advantage of this connection is that it provides a more stable ping and is protected from external radio interference, which is critical for online gaming or video conferencing.
- 🔌 Use the original cable or a certified equivalent with data support.
- 🔋 This method allows you to save your smartphone's battery while working.
- 🛡️ The connection is physically protected from external signal interception.
- 🚀 Data transfer speeds are often higher and more stable than Wi-Fi.
⚠️ Note: When connected via USB, your phone may request permission to access data. Select "Charging Only" or "File Transfer" mode, but the internet connection will still work via USB tethering, which must be enabled separately in the settings menu.
Solving common connection problems
Despite the simplicity of setup, users may encounter a number of difficulties. One of the most common issues is that the computer sees the network, but the internet doesn't work. This is often due to mobile data not being enabled on the phone, or the carrier blocking tethering.
Another common issue is constant connection drops. This can be caused by energy-saving algorithms. MIUI, which aggressively disable background processes. To avoid this, go to battery settings and set the system processes responsible for the hotspot to "No restrictions."
It's also worth checking whether the limit on connected devices has been reached. You can limit the number of clients in the hotspot settings. If the limit is reached, new devices (like your PC) won't be able to connect until one disconnects.
Hidden APN settings
If your internet isn't working, your carrier's Access Point Name (APN) settings may be out of order. Go to Settings -> SIM cards & mobile networks -> Access Point Names (APN) and tap "Reset to default settings."
In rare cases, changing the broadcast channel helps. If all the neighbors in an apartment building are on channel 6, interference will occur. In the advanced settings of the access point (if your model Redmi (This allows) try manually changing the channel to 1 or 11.
Frequently Asked Questions (FAQ)
Why can't my computer see my Redmi's Wi-Fi network?
You most likely selected the 5 GHz band, but your computer's network adapter is too old and doesn't support this standard. Switch your access point to the 2.4 GHz band in your phone's settings. Also, check that the network name (SSID) isn't hidden in the visibility settings.
