Modern smartphones have long ceased to be just devices for calls, becoming full-fledged mobile offices and entertainment centers. Xiaomi Redmi 8, despite its budget status, has all the necessary features to create a personal area of wireless Internet access, this is especially true in situations where a fixed router is not available, and a laptop or tablet urgently needs access to the network.
The MIUI modem feature is quite convenient, but users often have questions about security settings and frequency range. Unlike more expensive flagships, there are nuances that must be taken into account for stable distribution. The correct configuration will not only provide Internet to other gadgets, but also optimize battery consumption.
In this guide, we will take a closer look at the whole process of turning your smartphone into an access point, touch on the technical aspects of frequency selection, password settings, and consider possible problems with customer connection, and understand these mechanisms will help you use the power of mobile traffic in the most efficient way.
Device preparation and network settings check
Before you activate the modem modem, you need to make sure that the basic parameters of mobile communication are configured correctly. SIM-A map with data on, because that's the channel that's going to be broadcasting the Internet. Check the status of the connection at the top of the screen where the icon should be on. 4G or+.
It is also important to consider the current signal level, because the quality of the distributed Wi-Fi depends on the quality of reception by the phone itself. If the signal indicator shows one division or constantly jumps, the speed on the connected devices will be low, in such cases it makes sense to find a place with better coverage or use an external antenna, if the design of the case allows.
Uncontrolled distribution of traffic on a laptop can quickly exhaust the limits of the package, as computers often begin background updates or synchronization of cloud storage. Make sure you have unlimited tariff or sufficient gigabytes for planned tasks.
⚠️ Note: Before turning on the access point, make sure that your tariff plan does not have a restriction on the access point. P2P-traffic or distributions, otherwise the operator may block access or write off additional funds.
To enter network settings, use the standard path through the control panel, which will quickly check the current status of the connection and if necessary, switch the network mode. Sometimes it takes a few seconds for the system to register with the network after turning on air mode, so do not rush to activate the distribution.
Activation of Wi-Fi access point in the MIUI menu
The process of turning on the modem in the MIUI shell is based on a logical menu structure that is accessible even to beginners. The first step is to go to the basic settings of the device, where the Located partition is responsible for all kinds of wireless connections, and here are the key parameters for managing the Internet connection.
Find Wi-Fi Access Point in the list of available options. In some firmware versions, it may be called a Portable Wi-Fi Router or have a similar name depending on localization. Once you click on this section, you will see a master switch that activates the distribution function.
Once the switch is turned on, the smartphone will start broadcasting a wireless signal. By default, the system will suggest using a standard network name that usually contains a device model, such as Redmi 8. This name will be seen by other users when searching for available networks within range.
☑️ Pre-insertion check
The smartphone switches to receiving mode only over the mobile network, becoming a gateway for other devices, which is standard behavior for most Android devices.
Set up network name and security parameters
The security of your personal network is a critical aspect that cannot be ignored. By default, Xiaomi Redmi 8 can offer weak protection or a standard password that is easy to pick up. Go to the access point settings to change the network name (SSID) to a unique one, by which you easily recognize your device in the list of available ones.
The WPA2 PSK encryption protocol is recommended to protect data. This standard provides reliable encoding of transmitted traffic, preventing passwords and personal information from being intercepted by attackers. Older protocols, such as WEP, are considered outdated and do not provide the proper level of protection.
The password should be complex enough to be unguided by brute force, but easy to enter on guest devices. The optimal length is 8 to 15 characters, including different case letters and numbers. Avoid using simple sequences like "12345678" or date of birth.
⚠️ Warning: Don't use a public network without a password in public places. Anyone in range will be able to connect to your traffic and potentially access data on your phone.
You can also hide SSIDs in the settings menu, making the network invisible to general search, in which case you have to manually type the network name on the client device to connect, which adds an additional layer of privacy, although it makes it a little more difficult to connect new gadgets.
Choice of frequency range: 2.4 GHz or 5 GHz
One of the important settings in Xiaomi Redmi 8 is the choice of broadcast frequency.The smartphone allows you to switch between the 2.4 GHz and 5 GHz bands, each of which has its own advantages and disadvantages. Understanding the difference between the two will help you optimize the speed and range of the signal.
The 2.4 GHz band is more common and compatible with almost all devices, including older laptops and tablets. It has better penetration through walls and floors, providing a stable signal at a greater distance from the phone. However, this range is often overloaded with signals from neighboring routers and household appliances.
5 GHz offers significantly higher data rates and is less prone to interference, ideal for watching high-resolution video or online gaming, but the range of such a signal is smaller and it travels through obstacles less, so devices should be close to the phone.
Effect of frequency on battery
When choosing a frequency, be guided by the capabilities of the receiving device. If your laptop supports only the old standard, turning on 5 GHz on the phone will not work - the gadget simply will not see the network. In most cases, for universal compatibility, it is better to leave the standard value of 2.4 GHz.
Managing Connected Devices and Limits
Shell MIUI It provides a convenient tool to monitor those who are connected to your access point. The access point menu displays a list of active customers from their MAC-This allows you to control who is using your Internet and, if necessary, block unknown devices.
To prevent congestion, you can set a limit on the number of devices you can connect. Usually, the default is a limit of 10 devices, but for a smartphone with mobile Internet, this is too much. It is recommended to reduce this parameter to 3-5 devices to ensure a comfortable speed for each user.
There's also a whitelist that only allows pre-approved devices to connect, which is the maximum level of control that even if you know your password, you can't get a third party to connect without your permission in the settings. MAC-addresses of each permitted gadget.
| Parameter | Recommended value | Impact on work |
|---|---|---|
| Max. Devices. | 3-4 pcs. | Keeps the speed up for every customer |
| Range. | 2.4 GHz | Better compatibility and range |
| Time out | 10 minutes. | Automatic shutdown to save battery |
| Encryption | WPA2 PSK | Protection of data from interception |
Check the list of connected devices regularly, especially if you are sharing the Internet in a public place. The presence of an unfamiliar gadget in the list may indicate that your password has been compromised or matched, in which case you should immediately change your password and reconnect your devices.
Optimizing energy consumption and time out
The hotspot mode is one of the most energy-intensive processes for a smartphone. The Wi-Fi module is in constant data mode, causing the housing to heat up and quickly drain the battery. On the Redmi 8 model with its capacious battery, this is less critical, but still requires attention.
The hotspot settings have a Time Out hotspot feature that allows you to automatically turn off the Wi-Fi distribution if no one is connected or active within a given time (e.g. 10 or 15 minutes) to the network, a useful option that saves charge if you forgot to turn off the modem manually.
To minimize heat, it is recommended to remove a dense case from your smartphone during prolonged Internet distribution. Overheating can lead to trolling (reduced processor performance), which will adversely affect the processing speed of network packets. Also try not to leave the phone under direct sunlight.
💡
If you plan to give out the Internet for a long time, connect your phone to a charger, which compensates for the high power consumption and prevents a sudden shutdown.
Using an energy-saving system mode can limit background activity, but sometimes it also reduces the power of the Wi-Fi transmitter. If you notice a drop in signal speed or range, try turning off the tight power saving restrictions for the access point service.
Solution: If devices can't see the network
Sometimes users are faced with a situation where a laptop or tablet does not detect the network created, although it is active on the phone. Most often the problem is incompatible encryption standards or frequency. Try changing the type of security from WPA3 to WPA2, as older Wi-Fi drivers may not support new protocols.
Another common reason is the network settings cache on the connected device. If you've previously connected to the network with the same name but different parameters, the gadget may try to use the old stored data. The solution is simple: select the network on the client and click "Forget the network", then try to connect again.
In rare cases, a failure can occur on the Android system itself, which can be helped by resetting the network settings or a banal smartphone reboot, and also check if the Invisibility mode (hidden SSID) is turned on, which requires manually entering the network name.
⚠️ Note: If after all the manipulations the Internet on the connected device is, but the pages do not load, check the settings DNS. Try to prescribe static DNS (For example, from Google: 8.8.8.8) in the Wi-Fi settings on the client device.
Make sure that the browser is open on the phone and any page loads. Sometimes the access point is working, but the mobile Internet is blocked by the operator due to the completion of the package or technical work. The “No Internet access” indicator on the client often indicates exactly the problem with the source of traffic.
Alternative ways to distribute the Internet
In addition to the classic Wi-Fi, Xiaomi Redmi 8 supports other methods of transferring Internet connection. USB-The modem allows you to transfer the Internet to your computer via cable, which provides a more stable connection and charges the phone at the same time.
Bluetooth modem is another option that consumes significantly less power than Wi-Fi. The data transfer speed here will be lower, making the method suitable only for surfing in text mode or working with messengers. To activate, you need to create a pair between devices and include the corresponding switchboard in the modem menu.
Each method has its own use cases: Wi-Fi is convenient for connecting multiple gadgets quickly, USB is reliable for work, and Bluetooth is economical in critical situations.
💡
USB-Modem is the best choice for long-term work behind a laptop, as it eliminates signal loss and charges the phone, unlike Wi-Fi distribution.
In conclusion, the smart hotspot setting turns your Redmi 8 into a powerful tool to work anywhere in the world, and following security rules and optimizing your settings will allow you to stay online without unnecessary hassle and cost.
