Smartphones of the series Redmi Note from the company Xiaomi have remained one of the most popular devices on the market for many years, offering excellent value for money. Model Redmi Note 7Despite its age, it's still actively used by millions of people thanks to its reliable hardware and up-to-date MIUI user interface. One of the key features of this modern gadget is the ability to turn it into a mobile router, which is especially useful when traveling or without wired internet.
The process of activating the modem mode in the system Android with shell MIUI While it's designed to be as simple as possible for the end user, it hides a number of important security and performance settings. Many owners simply enable the feature without considering frequency band selection or data limits, which can lead to rapid battery drain or unauthorized connections. In this article, we'll walk you through all the setup steps so you can use your phone as a fully-fledged hotspot.
It's important to understand that distributing internet is an energy-intensive process that also affects the device's temperature. When actively distributing Wi-Fi, the Redmi Note 7 body may become hotter than usual due to the simultaneous operation of the signal receiving and transmitting modules. Properly configured settings will help minimize the load on the battery and processor, ensuring a stable connection for connected devices.
Preparing your smartphone to work in router mode
Before activating the hotspot, make sure your device is ready to use as a modem. First, check your SIM card status and mobile data connection, as this is what will be used for data transfer. If the SIM card is locked with a PIN or the account balance is zero, the hotspot will not work, even if all settings are correct.
It's also worth paying attention to the battery level. Access point mode Wi-Fi Consumes significantly more power than normal standby or surfing mode. It's recommended to keep the battery above 50% or connect the phone to an external battery if you plan to use it for extended periods. Ignoring this advice can result in the device running out of battery at the most inopportune moment.
- 📱 Make sure you have a SIM card inserted with an active tariff plan and data package.
- 🔋 Check the battery charge level - preferably more than 40-50%.
- 📶 Make sure you have a stable mobile network (4G/LTE or 3G icon).
- ⚙️ Check if Airplane mode is enabled, which blocks all wireless interfaces.
Another important aspect is the version of the operating system and shell. Owners Redmi Note 7 could update the device to different versions MIUI (from 10 to 12 and above), and the settings interface may differ slightly. However, the basic logic of the system remains unchanged, and menu items retain their names and locations in most cases.
⚠️ Note: If you're using a custom firmware or an unlocked bootloader, the default menu paths may differ. In such cases, we recommend consulting the documentation for your specific firmware build.
Activating the access point through system settings
The primary method for enabling internet tethering is in your smartphone's system settings. This is the most secure method, allowing you to configure all necessary security settings at once. First, unlock your phone's screen. Redmi Note 7 and find the "Settings" icon, which usually looks like a gear, on your desktop or in the application menu.
In the menu that opens, find the section responsible for wireless connections. Depending on your interface language, it may be called "Connection and Sharing" or simply "Wi-Fi Hotspot." This is where all the controls for your device's network interfaces are located.
Find the item Wi-Fi hotspot and tap it. This will open the modem management menu. Here you'll see a switch, which is set to "Off" by default. Toggle it on. After this, your phone will begin generating a wireless network, the default name of which will include your device model, for example, Redmi Note 7.
☑️ Pre-launch check
Once enabled, you'll see a notification in the status bar indicating the hotspot is active. The number of connected devices will also be displayed here. This is a basic setup, but for security reasons, we recommend changing the default settings, which will be discussed in the next section.
Setting up a network name and security password
Using the factory default network name and password is a recipe for security problems. The default network name often contains your phone model, giving potential attackers information about your device. The default password may be too simple or well-known, so changing it is essential.
To change the settings, go to the menu Wi-Fi hotspot settings (This option is often located directly under the power switch or in the "Access Point Settings" submenu.) Here you'll see the "Access Point SSID" or "Network Name" field. Enter any convenient name that will make it easy to identify your network in the list of available connections, such as "Home_Router_7" or "My_Redmi_Net."
Next, you need to set a strong password. The system will prompt you to select the encryption type. To Redmi Note 7 the standard is WPA2 PSK, which provides sufficient security for home use. In the password field, enter a combination of letters and numbers at least 8 characters long.
- 🔒 Use a combination of uppercase and lowercase letters to make your password more complex.
- 🔢 Add numbers and special characters if your keyboard allows them.
- 🚫 Avoid simple sequences like "12345678" or "password".
- 📝 Write down your new password in a safe place so you don't forget it.
Why is it important to change SSID?
Changing your network name (SSID) not only helps hide your device model from prying eyes but also avoids confusion if you have other Redmi Note 7 phones nearby with factory settings. A unique name will make it easier to find your network in public places.
After entering all the information, be sure to click the "Save" button or the checkmark in the upper right corner of the screen. Your phone may briefly interrupt the connection to apply the new security settings. Your network is now protected from accidental connections from your neighbors.
Selectable frequency range: 2.4 GHz or 5 GHz
One important setting that is often overlooked is the choice of frequency range for the signal being broadcast. Redmi Note 7 Supports dual band operation: 2.4 GHz and 5 GHz. Understanding the differences between them will help you optimize connection speed and stability for your connected devices.
Range 2.4 GHz is more versatile. It provides better signal penetration through walls and has a longer range. However, this range is often congested due to microwave ovens, Bluetooth devices, and neighboring routers, which can reduce actual data transfer speeds.
Range 5 GHz Offers significantly higher speeds and is less susceptible to interference. It's ideal for watching high-definition video or online gaming. However, its range is shorter, and the signal penetrates obstacles less effectively. Furthermore, older devices may simply not detect the network in this range.
| Parameter | 2.4 GHz | 5 GHz |
|---|---|---|
| Transfer speed | Average | High |
| Range | Big | Less |
| Permeability of walls | Good | Average |
| Compatibility | Maximum | New devices only |
You can change the band in the access point settings menu by selecting "AP Band." The default setting is often "2.4 GHz" for maximum compatibility. If you're only sharing internet with a modern laptop or tablet, it might make sense to switch to 5 GHz.
Managing connected devices and limits
Shell functionality MIUI Allows you to not only share your internet connection but also control who connects to it. This is a useful feature if you want to limit the number of users or block an unknown device that has somehow learned your password.
The access point menu usually displays a list of connected clients. By clicking on the device name or the settings icon next to it, you can view detailed information, including the IP address, MAC address, and the amount of data transferred. Some firmware versions allow you to block specific devices directly from this list.
You can also set a connection limit. You can set the maximum number of devices allowed to connect simultaneously (usually up to 10). This will prevent overloading your phone's processor and data connection if someone tries to connect to your network en masse.
- 👥 Check the list of connected devices regularly.
- 🚫 Block unknown devices through the client management menu.
- 🔢 Set a reasonable user limit (3-5 devices is optimal).
- 📊 Track the amount of traffic spent in statistics.
⚠️ Note: The interface for managing connected clients may vary depending on the MIUI version. In some builds, the detail is limited to the total number, without the ability to block by MAC address.
Don't forget about traffic limits. You can set a data transfer limit in the hotspot settings. Once the limit is reached, data sharing will automatically turn off. This will protect your data plan from unexpected charges if you forget to turn off the hotspot.
Alternative distribution methods and quick activation
In addition to deep diving into the settings, the system Android offers quicker ways to activate tethering. The most common is using the notification panel (or shade). Swipe down from the top of the screen to open the control center and find the "Wi-Fi Hotspot" icon.
A long press on this icon in the notification shade usually takes the user directly to the corresponding settings menu, bypassing the main "Settings" menu. This saves time when quickly checking a password or changing a network name. Many users also use widgets on their desktop for instant access.
Another method is to share the internet via a USB cable. This is a great option if you need to share the internet with your computer but its Wi-Fi module is faulty, or if you want to save your phone's battery (since the phone can charge via the cable). To do this, connect Redmi Note 7 to the PC with a cable and select "USB modem" in the access point menu.
Using a USB modem also provides a more stable connection without packet loss, which is critical for video calls or online streaming. However, in this mode, the phone will not be able to simultaneously share Wi-Fi with other devices.
Common problems and their solutions
Despite the simplicity of setup, users may encounter various difficulties. One of the most common issues is when other devices see the network but are unable to connect, or when the connection is established but the internet is not working. This is often due to APN settings or operator blocking.
If the internet isn't working on connected devices, check that mobile data is enabled on your phone. Sometimes the system allows you to enable a hotspot even if data is disabled, but in this case, there won't be anything to transmit. Also, try restarting your smartphone—this is a classic but effective solution for temporary network module failures.
Another issue that can arise is rapid battery drain. As mentioned earlier, hotspot mode generates significant heat. If the phone overheats, the system may forcefully disable the Wi-Fi module to protect its components. In hot weather, avoid covering the phone and keep it in an open area.
Why won't my phone let me turn on the hotspot?
This most often happens if a SIM card isn't inserted, or if mobile data is disabled in the settings. Also, check if there are any restrictions in your parental controls or antivirus software.
Is it possible to share Wi-Fi if the phone is connected to Wi-Fi?
Most smartphones, including the Redmi Note 7, cannot simultaneously receive and broadcast Wi-Fi. The phone must switch to the mobile network to broadcast. However, there are advanced root-based methods that can bypass this limitation.
How many devices can be connected to Redmi Note 7 at the same time?
Technically, MIUI allows you to connect up to 10 devices. However, the actual number depends on the processor load and carrier signal stability. For a comfortable experience, we recommend no more than 3-4 active users.
Does Wi-Fi sharing affect mobile internet speed?
Yes, the speed is shared among all connected clients. If one device starts downloading a large file, the speed on other devices will drop. Furthermore, the signal broadcasting process itself places additional load on the radio module.
In conclusion, it is worth noting that Redmi Note 7 It has all the necessary tools for full-fledged operation as a mobile hotspot. Properly configured settings will allow you to effectively use mobile internet in any setting, whether it's an office, a café, or a country house.
