Modern smartphones have long ceased to be just devices for making calls, turning into universal tools for work and entertainment that require constant access to the network. Model Xiaomi Redmi 7, despite its age, remains a popular device that can effectively perform its function mobile router in the field. This feature becomes critical when landline internet is unavailable and a laptop or tablet urgently needs a connection.
The process of activating modem mode in the shell MIUI It's implemented intuitively, but it hides a number of settings that affect connection stability. Device owners need to understand the difference between a normal power-on and a proper one. frequency configurationto ensure maximum data transfer speed. Below, we'll detail each setup step and any potential nuances.
Using your smartphone as an internet source requires paying attention to battery consumption, as the module Wi-Fi In access point mode, the device consumes a significant amount of power. Properly preparing your device will prevent unexpected shutdowns at the most inconvenient moment. Let's move on to the practical part and configure your device for efficient operation.
Preparing the device and checking the tariff
Before you begin configuring the software, you need to make sure your device is physically ready to transmit data. First, check for the presence of SIM cards in the appropriate slot and make sure the data service is activated. Without a working mobile internet connection, sharing the data connection with other devices will not be possible, even if the sliders in the menu are enabled.
Pay special attention to the terms of your mobile operator's plan. Many providers impose limits on the amount of data that can be used while connected. access points, or even block this feature on certain plans. If the internet on a connected laptop doesn't work after enabling data sharing, the problem is often due to restrictions imposed by the service provider.
⚠️ Note: Some carriers may automatically detect traffic distribution based on the TTL value and block the connection. Before purchasing additional packages, make sure your plan allows you to use your smartphone as a modem.
It's also recommended to check the signal strength in the location where you plan to work. For stable distribution to multiple devices, it's important to have a strong network connection. 4G/LTEIf the signal is weak, the speed on connected gadgets will be low, and the battery Redmi 7 will discharge faster due to the module's constant attempts to find a network.
Activating a Wi-Fi hotspot
The basic process of enabling modem mode in the system Android shell-based MIUI It only takes a few seconds. First, unlock your smartphone and go to the main settings menu. This can be done in two ways: via the gear icon on the home screen or via the quick actions panel, which is accessed by swiping down from the top.
If you chose the Settings option, find a section called "Wi-Fi Hotspot" or "Personal Hotspot." Depending on your firmware version, this option may be under the "Connections and Sharing" category or in a separate menu. Tap the toggle to activate the feature, after which your smartphone will begin broadcasting the network.
☑️ Check before starting distribution
Once activated, a special icon will appear at the top of the screen indicating that the hotspot is active. Now any device within range will be able to detect your network by name. However, to prevent unauthorized access, password must be installed without fail.
Setting up security and network name
Data security is a top priority when using public or private networks. By default, the system suggests setting a standard network name, which often includes the phone model, for example, Redmi 7_XXXXIt is recommended to change this name to something more neutral or personalized to avoid attracting unnecessary attention from outsiders.
To change the settings, click on the name of your access point or select "Configure access point." In the menu that opens, you can set a new network name (SSID) and a strong password. The system supports various encryption types, but the standard is the optimal choice. WPA2 PSK, which provides reliable protection against hacking.
The password must contain at least 8 characters, including uppercase and lowercase letters and numbers. Avoid using simple combinations like "12345678" or your date of birth, as these can be easily guessed automatically. Save your changes by clicking the checkmark in the upper-right corner of the screen.
Why can't the network be left open?
An open network allows anyone within range to connect to your internet. This will not only reduce speed but also potentially expose your devices on the local network to attacks by malicious users who can intercept unencrypted data, such as passwords for websites without HTTPS.
Select 2.4 GHz or 5 GHz frequency range
One important setting, often overlooked by users, is frequency band selection. In the access point menu Xiaomi An option to "Use the 5 GHz band" is often present. By default, the 2.4 GHz band is enabled, which provides a longer signal range but is slower and susceptible to interference from other devices.
The 5 GHz band offers significantly higher data transfer rates and less interference from nearby routers and appliances. However, it has a shorter range and is less effective at penetrating walls. If you're in the same room as the device you're connecting to and speed is important (for example, for watching 4K video), it's best to switch to 5 GHz.
Keep in mind that older laptops or tablets may not support the 5 GHz frequency. In this case, the device simply won't detect your network. If you're unsure of the specifications of the device you're connecting to, stick with the standard 2.4 GHz for maximum performance. compatibility.
Managing connected devices
You can control who's using your internet through the access point's management menu. Accessing this section will show you a list of all currently connected devices and their MAC addresses. This allows you to monitor in real time who's hogging your bandwidth.
If you spot an unfamiliar device, you can immediately block it by clicking the corresponding button next to its name. This menu also often includes a "Whitelist" feature, which allows connections only to pre-approved devices. This provides a higher level of security, preventing password guessing.
The system also displays the amount of data transferred via the access point. Regularly checking these statistics helps you manage your traffic consumption, especially if your plan has a limited number of gigabytes. Statistics can be reset manually at the beginning of each billing cycle.
| Parameter | 2.4 GHz band | 5 GHz band | Recommendation |
|---|---|---|---|
| Transfer speed | Up to 150-300 Mbps | Up to 400-800+ Mbps | For videos and games |
| Range | High (up to 50 m) | Medium (up to 20 m) | For large spaces |
| Wall permeability | Good | Bad | For different rooms |
| Compatibility | 100% of devices | New devices only | For old laptops |
Battery optimization and energy saving
Hotspot mode is one of the most power-hungry processes for a smartphone. The wireless module operates in constant active transmission mode, which causes the device to heat up significantly. Redmi 7 and rapid charge loss. A lithium-ion battery degrades faster under such loads if it's frequently allowed to overheat.
To extend battery life, we recommend reducing screen brightness to a minimum or turning off the display completely after enabling hotspot sharing. You should also close background apps that may be consuming processor resources. You can enable power saving mode in the battery settings, but make sure it doesn't disable the hotspot itself.
⚠️ Caution: If you plan to use your phone as a stationary router for an extended period of time, remove the protective case for better heat dissipation and, if possible, connect the device to an external power source.
There's an "Access Point Timer" feature that automatically turns off the hotspot if no one is connected for a certain amount of time. This is a useful feature that prevents you from forgetting to turn off the hotspot and leaving your phone with a completely dead battery.
