The modern smartphone has long ceased to be just a means of communication, turning into a universal tool for solving work tasks anywhere in the world. Model Redmi Note 7Despite its age, the Wi-Fi router remains a popular device thanks to its balanced performance and high-quality display, making it an excellent choice for a portable router. Situations often arise when you urgently need to connect a laptop or tablet to the Internet, but a wired connection or a separate router is not available.
In such cases, the function comes to the rescue Wi-Fi hotspots, built into the MIUI shell. Enabling this option allows you to broadcast 4G or LTE mobile internet to other devices, creating a local network. The setup process is Xiaomi has its own nuances that differ from pure Android, so it is important to know where to look for the required switches.
In this article, we'll detail the steps for creating a wireless connection, including security settings and frequency bands. You'll learn how to optimize your access point for maximum speed and minimal battery drain. Redmi Note 7.
Basic Wi-Fi hotspot setup
To get started, you need to go to the corresponding operating system settings menu. On smartphones Xiaomi with shell MIUI The path to this feature may not be obvious to a beginner, as it is hidden deep within system settings. Open the app. Settings on the home screen or in the notification shade.
In the list that opens, find the section that is usually called Wi-Fi hotspot or Personal hotspotIn some firmware versions, this item may be located inside the menu. Additional functions or Connection and sharingBy clicking on this item, you will see the main switch that activates the modem mode.
⚠️ Important: Before turning on the hotspot, make sure that the mobile Internet is enabled on the SIM card and there is available traffic, otherwise the connected devices will not be able to access the network.
Once the slider is activated, the phone will begin broadcasting a signal. However, the default settings may not be optimal: the network name often contains the phone model, and the password may be too simple or too difficult to enter manually. Therefore, immediately go to the configuration menu to change the default settings.
Here you can ask a new one SSID (network name), which will be displayed when searching on other devices. It is recommended to use Latin letters and numbers for better compatibility with older devices. A password is also set in this menu; it must be at least 8 characters long to ensure basic security.
Selecting a frequency range and safety standards
One of the key features of setting up an access point on Redmi Note 7 is the ability to select a frequency range. A switch between bands is often available in the Wi-Fi configuration menu. 2.4 GHz And 5 GHzUnderstanding the difference between them is critical to connection stability.
The 2.4 GHz band is more versatile and has a longer range. It provides coverage over a larger area, allowing you to be further away from your phone, but data transfer rates are lower, and the airwaves are often clogged with signals from neighboring routers and Bluetooth devices. This option is ideal for older laptops or if your phone is kept in your bag.
The 5 GHz band offers significantly higher speeds and is less susceptible to interference, but its range is significantly shorter. The 5 GHz signal penetrates walls and obstacles less effectively. If you need maximum speed for downloading files or streaming, choose this band, but keep your devices close together.
It is also important to select the correct encryption protocol in the security settings. Redmi Note 7 standards are relevant WPA2 PSKUsing an open network or outdated WEP encryption makes your data vulnerable to interception. Always set a password, even if you share the internet with only your own devices.
Managing connected devices and limits
You can control who's connected to your network through the client list in the access point menu. The MAC addresses and names of connected devices are displayed here. This is a useful feature for identifying "neighbors" who might have guessed your password.
The system allows you to limit the number of connected devices. By default, the limit can be set to 10 clients, but to save data and battery life Redmi Note 7 It's best to reduce this value to 2-3. Exceeding the limit will prevent new devices from logging in.
Some MIUI versions offer a "Blacklist" feature or the ability to block specific MAC addresses. If you spot an unknown device, you can block its access with one click. Once blocked, the device will be unable to connect, even with the correct password, until the restriction is lifted.
Advanced users can set a sleep timer. You can set the hotspot to automatically turn off if no one is connected for a certain amount of time (e.g., 1, 5, or 10 minutes). This prevents unnecessary battery drain when you forget to turn off tethering.
| Parameter | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Transfer speed | Up to 150-300 Mbps | Up to 400-800+ Mbps |
| Range | High (up to 30-40 m) | Medium (up to 15-20 m) |
| Penetration ability | Good | Low |
| Airtime congestion | High | Low |
Sharing the Internet via USB and Bluetooth
Although Wi-Fi is the most popular method of distribution, Redmi Note 7 It also supports alternative methods that can be useful in specific situations. For example, a USB modem allows you to simultaneously charge your phone and provide a stable wired connection to your computer.
To activate the USB modem, connect your phone to the PC with a high-quality cable. The Wi-Fi hotspot menu item will become active. USB modemThe computer recognizes the phone as a new network connection (Ethernet). This method ensures minimal latency (ping) and doesn't drain the smartphone's battery.
A Bluetooth modem is an extremely energy-efficient option, but offers very low data transfer rates (no more than 1-2 Mbps). It's only suitable for text messaging or messaging when other methods aren't available. It requires pairing devices via Bluetooth.
⚠️ Note: When using USB modem, make sure you have ADB drivers or standard Android drivers installed on your computer, although Windows 10/11 usually installs them automatically.
Another advantage of a wired connection is the absence of radio interference. If you're in a densely populated area and the airwaves are clogged with hundreds of Wi-Fi networks, a USB cable will be the only way to get a stable connection without packet loss.
☑️ Checking readiness for distribution
Hidden Network and Advanced SSID Settings
In the access point settings Xiaomi there is an option Hide device (or "Hidden Network"). When you enable this option, your Redmi Note 7 Stops broadcasting the network name (SSID). Other users won't see your access point in the list when searching for available Wi-Fi.
To connect to a hidden network, you must manually enter the network name (SSID) and password on the receiving device. This adds a layer of security through obscurity, but it doesn't provide complete protection against hackers using traffic sniffers. However, it does eliminate unnecessary connection requests from neighbors.
Use this feature only if you really want to hide your network from prying eyes.
If you have forgotten the name of the hidden network, you can find it in the access point settings on the phone itself in the field SSIDYou can also disable the privacy feature at any time, making your network visible to everyone around you.
Energy optimization and overheating
Hotspot mode is one of the most power-consuming processes for a smartphone. Redmi Note 7 It is equipped with a 4000 mAh battery, which is a good indicator, but active data transfer via Wi-Fi can drain the battery in 3-4 hours of continuous operation.
The main cause of rapid battery drain and possible overheating is operating the radio module at maximum power, especially in the 5 GHz band or when the cell tower signal is weak. The phone begins to heat up in the camera area and the top of the case.
To minimize the consequences, follow these recommendations:
- 📶 Reduce screen brightness or turn off the display, as it is the second largest energy consumer.
- 🔋 Remove the protective case if it is thick and interferes with heat dissipation, especially in hot weather.
- 📵 Disable background apps that may consume traffic (updating email, syncing photos).
If your phone reaches a temperature where the system warns of overheating, the hotspot may be automatically disabled to prevent damage to components. In such cases, take a break or connect the device to an external cooling source (a fan).
Why does my phone get hot when using Wi-Fi?
When using modem mode, the smartphone's processor and radio module operate in an enhanced mode. The radio frequency signal generates heat, and active data encoding and decoding places a strain on the CPU. This, combined with charging (if the phone is connected to a PC), increases the heat output. This is normal, but prolonged overheating can reduce battery life.
Common problems and solutions
Despite the stability of work MIUI, users may encounter common issues. For example, devices connect, but the internet doesn't work ("No internet access"). This is most often resolved by reconnecting the mobile data connection or restarting the phone.
Another common issue is the inability to find a network in the 5 GHz band on older laptops. In this case, you need to force the access point to switch to wireless mode. 2.4 GHz in the settings. Resetting the network settings on the receiving device also helps.
If your data transfer speed is extremely low, check your cellular signal strength. Modem mode cuts the speed in half because the radio module is transmitting and receiving simultaneously. Placing your phone near a window or on a higher surface may improve the situation.
In rare cases, resetting the access point to factory settings may help. This will delete saved passwords and network names, but will return the system settings to their original state, eliminating software conflicts.
Why isn't Wi-Fi hotspot working on my Redmi Note 7?
There could be several reasons: your data plan has run out, data saving mode is enabled, there's a radio module malfunction, or the service provider is blocking your data (check your plan's terms). Also, make sure there's no limit on the number of connected devices.
Is it possible to share Wi-Fi if the phone is connected to Wi-Fi?
On most smartphones Xiaomi Modern versions of Android and MIUI offer a Wi-Fi Sharing feature that allows you to broadcast your Wi-Fi data connection further. However, on older firmware versions, this feature may not be available, and your phone will prompt you to use mobile data.
How do I find out who is connected to my Wi-Fi?
Go to your phone's Wi-Fi hotspot settings. You'll see a list of connected devices with their names and MAC addresses. If you see an unfamiliar device, change the hotspot password—this will disconnect all users.
How many devices can Redmi Note 7 work simultaneously?
Technically, MIUI allows you to connect up to 10 devices simultaneously. However, actual performance will depend on processor power and cellular network signal strength. For stable operation, it is recommended to limit the number of active clients to 3-4.
