The modern smartphone has long ceased to be just a device for calls, becoming a universal tool for Internet access anywhere in the world. Owners of the popular Xiaomi Redmi 7 model often face the need to share mobile traffic with a laptop, tablet or phone of a friend when there is no wired Internet. Turning the device into a full-fledged wireless router is a regular feature of the MIUI operating system, which works stably and does not require the installation of third-party software.
The modem activation process takes just a few seconds, but there are important safety and power nuances to be aware of. Wi-Fi significantly increases battery load, so it’s important to monitor battery levels while the access point is active. In this article, we’ll go into detail about all the adjustment steps, signal optimization, and how to solve typical problems that users may encounter.
Understanding the wireless network will not only allow you to quickly connect your gadgets, but also to protect your data from unauthorized access. We will look at frequency settings, managing the list of connected devices and hidden menu features that are often overlooked.
Preparation of the device and checking the settings
Before you activate the hotspot, make sure your Redmi 7 has mobile data enabled.Without an active internet connection from the carrier, traffic distribution will be impossible even if the Wi-Fi indicator is on. SIM-Make sure your plan allows you to use your smartphone as a modem, as some carriers may block this traffic or require a separate payment.
Also worth paying attention to the current battery level. hotspot mode is one of the most energy-intensive processes in the Android system. If the battery is discharged below 20-30%, it is recommended to connect the device to the charger before starting active distribution of the Internet to avoid sudden shutdown.
☑️ Check before starting the access point
It is important to determine in advance what type of security will be used. By default, the system offers the most reliable encryption protocol that protects the communication channel from interception of data. Do not neglect to set a complex password, especially if you are in a public place where unauthorized users may be nearby to intercept traffic.
Step-by-step activation of the Wi-Fi access point
To start the router mode, you need to go to the main settings menu of the system. Find the Settings section and select the Wi-Fi Access Point. In some versions of the MIUI firmware, this item may be called Portable Hotspot or located inside the “More” menu in the wireless network group.
Once you log in, you'll see a switch that needs to be activated. The system can alert you that when the access point is turned on, your current Wi-Fi connection will be severed, because the wireless module cannot simultaneously receive and broadcast the signal at the same frequency.
💡
Use the widget in the notification curtain to quickly turn on the access point. To do this, lower the top bar and find the Wi-Fi Access Point icon, then hold your finger to go to the advanced settings.
Once activated, an icon will appear next to the signal indicator to notify you of modem operation. Other devices can now detect your Redmi 7 in the list of available networks. The default network name usually contains the device model, but it can be easily changed in configuration settings for easy identification.
Setting up security settings and network name
The security of your personal network depends on the right password and type of encryption. From the access point settings menu, go to the "Setting up the access point" section, where you can change the SSID (network name) to any word you like using Latin letters and numbers.
For the type of security, be sure to choose WPA2 PSK. This is a modern encryption standard that provides strong protection for transmitted data. Using an open network or an outdated WEP protocol makes your traffic vulnerable to third-party viewing, which can lead to theft of passwords from social networks or banking applications.
⚠️ Warning: Never set simple passwords like “12345678” or “password.” Attackers can pick up this combination in seconds and use your mobile traffic for illegal activities.
The password should contain at least 8 characters, including letters of different registers and numbers. Remember or write down the invented combination, because each time you connect the device, you will have to re-enter it. If you forget the password, you can always look at it or change it in the same settings menu.
Managing Connected Devices and Limits
One of the important features in Xiaomi Redmi 7 is the ability to control connected customers. The access point menu has a section called Connected Devices, which displays a list of all the gadgets that use your Internet in real time. You can see the name of the device and the amount of data transferred.
To prevent unauthorized access, it is recommended to set a limit on the number of users connected. Usually, the system allows you to choose a value from 1 to 10 devices, setting a limit of 3-5 devices is optimal for personal use and helps to maintain the connection speed.
Also available is the function “Black list”, which allows you to block specific devices on their MAC-If you notice an unknown device in the list of connected, immediately change the password and add the intruder to the blacklist to prevent reconnection.
Additional settings: frequency and timeout
In advanced settings (Access Point Settings → Additional), you can select the frequency range. Redmi 7 supports 2.4 GHz band, which provides better signal penetration, but can be congested in apartment buildings. The choice of frequency affects the stability and range of the network.
A useful feature is a timeout shutdown. You can set up an access point to automatically shut down if no device is connected to it for a certain time (1, 5 or 10 minutes), which helps save battery power if you forgot to turn off modem mode.
Why isn’t 5GHz running on Redmi 7?
Some users are trying to find the settings IP-address DHCP-In the standard shell. MIUI These parameters are hidden and configured automatically to make it easier to use. Manual interference with network settings without special knowledge can lead to the failure of the access point.
Typical problems and ways to solve them
Despite the stability of the work, users can face a situation where devices see the network but can not connect, or the connection is there, and the Internet does not work. Often the problem lies in the wrong date and time on the connected device or in the failure of the network settings of the smartphone itself.
If the Internet is not running on a connected laptop, try switching mobile data to 4G only on the Redmi 7 itself via an engineering menu or network settings. Sometimes the automatic choice of communication standard works incorrectly at low signal speeds.
| Problem. | Possible cause | Method of decision |
|---|---|---|
| Devices don't find the network | Hidden SSID or module failure | Reboot your smartphone, check visibility |
| The “failure to connect” error | Wrong password | Forget the network on the client and enter the password again |
| No Internet access | No traffic on SIM | Check the balance and settings of the operator's APN |
| Low transmission speed | Weak 4G signal | Move to the best coverage area |
In case of persistent errors, it is recommended to reset your network settings. Go to Settings → Advanced Settings → Restore and Reset → Reset your Wi-Fi, mobile networks and Bluetooth settings. This action will not delete your personal data, but will return network settings to factory values.
Optimizing energy consumption during work
The constant operation of the radio module in broadcast mode leads to heating of the case and fast battery discharge. Xiaomi Redmi 7 is equipped with a battery capacity of 4000 mAh, which allows you to work in router mode for several hours, but the intensity of screen use also affects the overall battery life.
To minimize energy consumption, it is recommended to turn off the smartphone screen and close background applications that consume traffic during the Internet distribution, and it is also worth turning off geolocation and Bluetooth if they are not used to reduce the overall load on the system.
💡
Using the original charger during the Wi-Fi distribution will prevent battery degradation due to heating and cooling cycles.
Watch the temperature of the device. If the case of the smartphone becomes too hot, take a break from use or remove the protective case for better heat sink. Overheating can lead to trottling of the processor and reduced data transfer speed.
