Modern smartphones have long since become universal tools that allow you to stay online in any situation. The device Xiaomi Redmi Note 7Despite its age, it remains a popular choice for those looking for a reliable gadget for everyday tasks, including creating a hotspot. Mobile Internet via Wi-Fi router from a phone often becomes the only way to connect a laptop or tablet when a fixed network is unavailable.
The process of activating modem mode on the shell MIUI It may seem simple, but there are nuances that affect connection speed and stability. Many users encounter network visibility issues or low data transfer rates without realizing the hidden settings. Understanding the technical aspects of a wireless module will help avoid common mistakes when configuring the system.
In this article, we'll cover every step of turning your smartphone into a fully-fledged internet source. We'll cover security, frequency band selection, and power consumption optimization. Proper setup will allow you to use mobile traffic as efficiently as possible, ensuring comfortable operation of connected devices.
Preparing the device and checking network settings
Before activating the data sharing function, you need to make sure that the smartphone itself has a stable connection to the operator's network. Without an active mobile Internet (3G, 4G, or LTE) hotspot creation is not possible. Check your SIM card balance and ensure data is enabled in your cellular network settings.
An important step is checking the signal strength. If the indicator shows one or two bars, the upload speed will be low and the connection will be unstable. In such cases, it is recommended to move to an area with better reception or use an external antenna, if the device's design allows it.
⚠️ Important: Before enabling the hotspot, make sure your plan allows internet tethering. Some carriers block this feature or require a separate subscription.
It's also worth paying attention to the battery's condition. Hotspot mode significantly increases power consumption, so make sure the battery level is sufficient for extended operation. If the battery is low, it's best to connect the device to a power source.
Step-by-step instructions for enabling the access point
To start the process, you need to go to the main system settings menu. On the shell MIUI This path is standardized, but may vary slightly depending on the firmware version. Open the section Settings and find the item Wi-Fi hotspot.
Inside the menu, you'll see a switch that activates tethering mode. Once enabled, your smartphone will begin broadcasting a wireless signal. By default, the network will be named after your model, for example, Redmi Note 7, which may not always be convenient for identification among many other signals.
☑️ Check before switching on
To change the network name and password, click on the corresponding fields in the configuration menu. complex password (WPA2 PSK) will protect your network from unauthorized connections. Avoid using simple combinations like "12345678."
Setting up frequency range and safety standards
One of the key settings that affects speed and compatibility is the frequency band selection. In the access point menu Xiaomi Often, you can choose between 2.4 GHz and 5 GHz. The 2.4 GHz band has a longer range but is susceptible to interference from household appliances.
The 5 GHz band offers higher data transfer rates and lower latency, but has a shorter range and is less able to penetrate walls. If you plan to connect modern devices near your smartphone, it's preferable to choose 5 GHz.
| Parameter | 2.4 GHz | 5 GHz |
|---|---|---|
| Speed | Up to 150 Mbps | Up to 866 Mbps |
| Range | High | Average |
| Penetration ability | Good | Low |
| Compatibility | All devices | New devices only |
In the security section, be sure to select an encryption protocol. WPA2-PersonalOlder standards, such as WEP, are outdated and do not provide adequate data protection. Modern encryption algorithms ensure that transmitted information cannot be intercepted.
Managing connected devices and limits
shell MIUI provides a convenient tool for monitoring connections. The access point menu displays a list of all devices currently using your internet connection. You can see the MAC addresses and device names.
The connection limit feature prevents bandwidth congestion. If you set a limit of, say, 3 devices, a fourth user won't be able to connect, even if they know the password. This helps conserve bandwidth. Internet speed for basic tasks.
⚠️ Note: The menu interface may change depending on MIUI system updates. If you don't see the items described, check for firmware updates or refer to the help section in Settings.
To disconnect a specific user, you can block them by MAC address. This will blacklist the device, making it impossible to reconnect without resetting the access point. Regularly monitoring the client list improves the security of your network.
Sharing the Internet via USB and Bluetooth
In addition to classic Wi-Fi, Redmi Note 7 Supports alternative data sharing methods. A USB modem allows you to share your internet connection with your computer via a cable. This method provides a more stable signal and simultaneously charges your smartphone.
To activate USB modem, connect your phone to your PC using a cable, go to the hotspot settings, and select the appropriate option. The computer will recognize the device as a network adapter. This method is ideal for desktop workstations where connection reliability is essential.
Why isn't my USB modem working?
A common cause is using a charging-only cable that doesn't support data transfer. Replace the cable with a high-quality one that supports Data Transfer.
Bluetooth modem is less commonly used due to its low data transfer speed, but can be useful for connecting older devices or specialized equipment. While speed in this mode is limited by the Bluetooth protocol, battery consumption is lower than using a Wi-Fi module.
Optimization of work and elimination
Sometimes users encounter a situation where the hotspot is enabled, but the internet is not working. This is often due to the carrier's APN settings. Check that the hotspot access fields in your mobile network settings are correct.
Device overheating is another common problem. When actively distributing CPU The phone and radio module are operating at their maximum capacity. Remove the case if it interferes with heat dissipation, and avoid placing the phone under pillows or on soft surfaces.
If connections are dropping after certain periods of time, check your power saving settings. The system may be forcibly disabling the hotspot to save battery. Add the "Hotspot" app to the exceptions list or set it to "Unrestricted" mode in the battery settings.
Frequently Asked Questions (FAQ)
How many devices can be connected to Redmi Note 7 at the same time?
Officially, MIUI allows for up to 10 simultaneous device connections. However, the actual number may be lower and depends on processor load, Android version, and data usage.
Why does the battery drain quickly when the hotspot is turned on?
Modem mode requires the radio module to operate continuously at high frequencies and actively transmit data, which is energy-intensive. For extended use, it's recommended to keep the phone connected to a charger.
Is it possible to share Wi-Fi if the phone is connected to a Wi-Fi network?
On most modern versions of Android and MIUI, this feature (Wi-Fi Repeater) is unavailable or requires root access. Typically, a smartphone can either receive Wi-Fi or share mobile data, but not both.
How to hide your network name from strangers?
In the access point's advanced settings, you can enable the "Hide Device" feature. This will prevent the network from appearing in the general list, and connecting will require manually entering the SSID and password on the client device.
