Modern smartphones such as Xiaomi Redmi 8, have powerful functionality that allows them to be used not only for communication but also as a full-fledged mobile router. This feature, known as "Wi-Fi Hotspot," turns your device into an internet source for laptops, tablets, or other gadgets that don't have their own SIM card. For owners Redmi 8 This is especially important since the model supports dual-band networks and has a capacious battery, which is critical when actively working in modem mode.
The process of activating Internet distribution in the shell MIUI It's quite user-friendly, but many users aren't aware of hidden settings that can significantly improve connection stability and data transfer speeds. Default settings often limit the number of connected devices or use outdated security protocols, which can lead to low speeds or connection issues with certain devices. Understanding the intricacies of the system mobile hotspot will help you avoid common mistakes.
In this article, we'll cover everything from enabling the basic feature to advanced frequency band settings and managing traffic limits. You'll learn how to protect your network from prying eyes, why some devices can't detect your access point, and how to extend battery life when running in router mode for extended periods. This knowledge will transform your Xiaomi Redmi 8 into a reliable tool for work and entertainment anywhere in the world.
Basic hotspot activation via settings
The first step to setting up a wireless network is to properly enable the feature in the system menu. Unlike some other manufacturers, Xiaomi Provides advanced access to settings directly from the notification shade or the main settings menu. To get started, unlock the screen and find the icon Settings, which usually looks like a gear. Inside the menu, find the section responsible for wireless connections, which in different firmware versions may be called "Wi-Fi Hotspot" or located under "Connection and Sharing."
Once you navigate to the desired section, you'll see a switch that activates tethering mode. However, simply enabling it isn't enough to ensure secure operation. Network name (SSID) By default, it often contains the phone model and a random set of characters, which isn't always convenient for searching on a client device. It's recommended to immediately rename the network to something recognizable, such as "My_Redmi8_Hotspot," to avoid confusion when searching for available connections in public places.
Particular attention should be paid to the password. Security system WPA2-PersonalThe default password is secure enough for home use, but it should be complex. Avoid simple combinations like "12345678" or your date of birth, as modern password-guessing programs can crack such protection in minutes. The ideal password contains mixed-case letters, numbers, and special characters.
⚠️ Attention: When changing the security type from WPA2 to open mode (no password), all transmitted data will be visible to anyone connecting to your network. Never conduct banking transactions over an open access point.
After configuring the basic settings, the access point is ready to use. Other devices can now detect your Redmi 8 in the list of Wi-Fi networks and connect using the specified password. The system will automatically assign the connected device an IP address from the internal range, providing full internet access via your operator's mobile network.
Advanced range and security protocol settings
For users looking for maximum speed or compatibility with older devices, Xiaomi Redmi 8 offers a choice of frequency bands. The "Access Point Settings" menu hides the "AP Band" option, where you can choose between 2.4 GHz and 5 GHz. Choosing the right band is critical, as it directly impacts signal range and data transfer speed. 2.4 GHz Provides better coverage and penetration through walls, but often suffers from interference in multi-family buildings.
Range 5 GHz, supported Redmi 8, offers significantly higher speeds and less interference, but its range is significantly shorter. If you plan to share internet with your laptop in the same room, 5 GHz is optimal for watching 4K video or playing online games. However, if your devices are far away or behind several walls, it's better to switch to 2.4 GHz for a more stable connection.
You can also configure SSID hiding in this section. If you enable the "Hide Device" feature, your access point will no longer appear in the general list of available networks on other devices. To connect, you'll need to manually enter the network name on the client device. This adds an extra layer of security, as random users won't even know your network exists, although this isn't a significant obstacle for hackers.
| Parameter | 2.4 GHz | 5 GHz |
|---|---|---|
| Transfer speed | Up to 150 Mbps | Up to 400+ Mbps |
| Range of action | High | Medium/Low |
| Penetration ability | Good | Bad |
| Interference level | High | Short |
Please note that the 5 GHz band may not be available in some regions due to regulatory restrictions. In this case, the system will automatically switch to available standards. Available channels can be checked and their load can be assessed using third-party Wi-Fi analyzer apps, which will help you select the least crowded frequency.
Why is 5GHz faster?
The 5 GHz band has wider data transmission channels and is less susceptible to interference from household appliances such as microwave ovens and Bluetooth devices that operate in the 2.4 GHz frequency.
Managing connected devices and limits
Controlling who is connected to your network is a crucial part of security and traffic management. In the interface MIUI The "Connected Devices" feature displays a real-time list of all devices using your internet connection. You can see the device name, MAC address, and data transfer volume, allowing you to quickly identify "unwanted guests" and disable them with a single tap.
To prevent unauthorized access, there's a "Whitelist" feature. By activating this mode, you allow connections only to devices whose MAC addresses are on the trusted list. All other connection attempts will be automatically blocked, even if the attacker knows the password. This is the most reliable protection method, although it does require initial manual configuration of each authorized device.
An important aspect is controlling mobile traffic consumption. Xiaomi Redmi 8 Allows you to set data transfer limits. You can set a maximum value, such as 1 GB or 5 GB, after which data tethering will automatically stop. This will protect you from unexpected bills from your carrier, especially if you don't have an unlimited plan.
- 📱 Identification: Each device has a unique MAC address, which can be used to accurately determine the type of gadget (iPhone, Windows, Android).
- 🚫 Blocking: The ability to instantly disconnect from a specific device without shutting down the entire access point.
- 📊 Statistics: View the amount of traffic used by each connected client during the current session.
Regularly checking the list of connected devices helps maintain high internet speeds. If you spot a device you don't recognize, immediately change the hotspot password and reconnect your devices with the new security key.
Optimizing power consumption and battery
Hotspot mode is one of the most power-consuming processes for a smartphone. Xiaomi Redmi 8 The device has a 5000 mAh battery, which is a good value, but active Wi-Fi data transfer and 4G/LTE operation simultaneously can drain the battery in 3-4 hours of intensive use. To extend battery life, it is recommended to reduce screen brightness or turn off the display completely after activating tethering.
System MIUI has built-in power-saving mechanisms that can aggressively limit background processes. To ensure the hotspot works reliably and isn't turned off by the system after a certain period of inactivity, you need to add the "Hospitality" app to the battery exception list. This is done through the menu. Settings → Battery → App power management, where you need to select the "No restrictions" mode for the system Internet distribution service.
It's also worth considering the case's heat. When using the modem for long periods of time, especially when using 4G/5G networks, the phone's processor and radio module can become significantly hot. This is normal, but if the temperature reaches critical levels, the system may reduce data transfer speeds or temporarily disable the Wi-Fi module to protect components. It's recommended to remove the protective case during extended tethering sessions.
⚠️ Attention: Don't cover your phone with fabric or other materials while using Wi-Fi. This interferes with heat dissipation and can lead to overheating and reduced battery life.
Using power-saving profiles, if available in your firmware version, can also help. Some users recommend disabling the search for other devices (Bluetooth, GPS) while sharing Wi-Fi to reduce the overall load on the smartphone's power system and focus resources on maintaining a stable internet connection.
☑️ Battery optimization
Solving common connection problems
Despite the reliability Xiaomi Redmi 8, users may encounter a situation where devices are unable to connect to the access point, or are connected but the internet is not working. Often, the problem lies in an incorrectly set frequency range. If a laptop or old tablet isn't seeing the network, try forcibly switching the AP band. 2.4 GHz in the access point settings, since many older receivers do not support the 5 GHz standard.
Another common cause is an ARP table overflow or an IP address conflict. A simple Wi-Fi reboot helps: turn off the access point, turn it on Airplane mode for 10 seconds, then turn it off and enable sharing again. This action will force the device to re-register with the operator's network and reset the network stacks.
If the problem persists, it's worth checking your mobile operator's APN (Access Point Name) settings. Sometimes, after a firmware update or SIM card change, these settings can become reset. Go to Settings → SIM cards & mobile networks → Select SIM → Access point names (APNs) and press the reset button to default settings. Correct APN settings are critical for internet access over a mobile network.
- 🔄 Reboot: A complete reboot of the smartphone often solves software failures of the communication module.
- 📡 Signal: Make sure your phone has a strong 4G/LTE signal; in areas with weak signal, Wi-Fi will be unstable.
- 🔒 Safety: Check if there is a MAC address filter installed that is blocking your device.
In rare cases, the issue may be with the carrier, blocking traffic distribution (TTL). Bypassing such restrictions requires more complex manipulations of the TTL at the system level, which may require root access, but in most cases, the default settings are sufficient.
Alternative distribution methods: USB and Bluetooth
In addition to classic Wi-Fi, Xiaomi Redmi 8 Supports internet tethering via USB cable and Bluetooth. USB tethering is the most stable and fastest data transfer method, as it provides a direct wired connection, eliminating speed loss over the air and conserving battery life by simultaneously charging the phone from the computer.
To activate USB modem, connect your phone to your computer using a cable, then select "USB modem" in the access point menu. The computer will recognize the device as a new network card. This method is ideal for desktop workstations where maximum speed and minimal latency (ping) are important, such as during video conferencing or online gaming.
Bluetooth modem is used much less frequently due to its low data transfer speed, but it can be useful in emergency situations when you need to transfer a small amount of text or connect a device without a Wi-Fi module but supporting the Bluetooth DUN profile. Speeds in this mode rarely exceed 1-2 Mbps, which is sufficient only for instant messaging apps.
⚠️ Attention: When using a USB modem, make sure the cable is working properly and supports data transfer, not just charging. Cheap "charge-only" cables will not allow tethering.
The choice of distribution method depends on your current needs. Wi-Fi is convenient for mobile devices and groups of users, USB is for working on a computer, and Bluetooth is a backup option for specific tasks. Flexibility Redmi 8 allows you to easily switch between these modes depending on the situation.
Why does my phone's battery drain quickly when using Wi-Fi?
Wi-Fi distribution requires both the receiver (to receive internet from the base station) and the transmitter (to create the local network) to operate simultaneously. This places a high load on the processor and radio module, resulting in high current consumption. Furthermore, converting the 4G signal to Wi-Fi and encrypting the data requires computing resources, which also consumes power.
Is it possible to share Wi-Fi if there is no SIM card on the phone?
No, to share mobile data, you need an active SIM card with a data plan. However, if your phone is connected to another Wi-Fi network, some versions of Android allow you to rebroadcast that signal (Wi-Fi repeater), but Xiaomi Redmi 8 in standard firmware it usually requires a mobile network to create an access point.
How many devices can be connected to Redmi 8 at the same time?
Technically, MIUI allows you to connect up to 10 devices simultaneously. However, the actual number depends on processor load and signal strength. Connecting more than 5-6 active devices may significantly reduce internet speed on each device, and the phone may become very hot.
Does Wi-Fi sharing affect the speed of mobile internet on the phone itself?
Yes, it does. The connection bandwidth is divided between the needs of the phone itself and the connected clients. If connected devices start downloading large files or watching videos, page loading speeds on the smartphone itself may drop, and ping (latency) will increase, which will be noticeable for online gamers.
