Every smartphone owner faces situations where they urgently need to provide internet access to a second device. Often, it is devices of the brand Xiaomi And Redmi become a lifesaver, allowing you to turn your mobile internet into a full-fledged access point. Modern operating systems based on Android with shell MIUI provide flexible tools for managing network connections, but their configuration sometimes raises questions among users.
You might need to share your data while traveling, in an office with poor coverage, or simply to save data on your tablet at home. The process of activating tethering on devices Redmi The developers have simplified the process as much as possible, but it conceals a number of subtleties that affect connection stability. Understanding these nuances will help you avoid common connection issues and ensure maximum data transfer speeds.
In this guide, we'll walk you through every setup step, from simple activation to advanced security settings. You'll learn how to choose the right frequency band, limit the number of connected devices, and protect your network from unauthorized access. This knowledge will help you effectively utilize your device's capabilities in any environment.
Preparing the device and checking network settings
Before you activate the modem mode, you need to make sure that your Redmi Ready to use as a router. The first step is to check for an active SIM card with an active data plan. Without this step, further steps are pointless, as the device simply has nothing to share.
Pay attention to the signal strength at the top of the screen. For stable hotspot operation, a strong 4G or LTE network is recommended. If the indicator shows EDGE or GPRS, the data transfer speed will be critically low, making internet use virtually impossible on the connected device.
It's also worth checking your mobile account balance or remaining data plan in advance. Many carriers automatically cut off network access when the limit is reached, which could interrupt your hotspot at the most inopportune moment. Make sure your account has sufficient funds and your data plan allows for use. modem mode.
It's important to note that some carriers may block or limit speed when using a phone as a router. This is a technical limitation of the provider, which can be circumvented by changing the value. TTL, but requires more in-depth knowledge. For basic use, simply ensuring the network is available is sufficient.
The classic activation method is through settings.
The most reliable and complete method for setting up a hotspot is to use the system menu. This method allows you to not only enable the feature, but also configure all the necessary security and performance settings. To begin, unlock the screen of your Redmi and find the application icon Settings.
In the list of options that opens, you need to find the section responsible for wireless networks. Depending on the shell version MIUIIt may be called "Access Point & Modem" or located under the "Connection and Sharing" tab. This is where all the internet connection controls are located.
Once you've navigated to the desired section, you'll see the "Wi-Fi Hotspot" toggle. Enable it by sliding the slider to the "On" position. The system will automatically create the network, but it's highly recommended to set up a name and password before connecting another device for the first time.
- 📱 Click on the name of the created network to change its identifier (SSID) to something recognizable.
- 🔒 Select "Password" and enter a complex character combination to protect against hacking.
- 📡 Set a safety standard WPA2-Personal for maximum compatibility and protection.
⚠️ Warning: Using an open network without a password allows any device within range to connect to your internet and potentially intercept your data.
After saving the settings, your smartphone will begin broadcasting a signal. Now, on the second device, open the list of available networks, find the name you created, and enter the password you set. If all steps are completed correctly, you will be connected successfully.
Quick activation via the notification shade
For users who need to quickly share internet on the go, there's a simpler method. It allows you to activate the hotspot with just a few taps, without having to delve into the depths of the system menu. This method is ideal for regular use.
To use this feature, swipe down from the top of the screen to open the control center. In the grid of icons, look for the antenna- or chain-like symbol labeled "Hot Spot." Tapping it instantly activates tethering mode.
If you don't see the icon you need in the first row, try swiping left or tapping the panel's edit button (usually a pencil or three dots). You can add a hotspot shortcut to the list of available widgets for quick access in the future.
☑️ Check before quick activation
It's worth noting that quick activation uses the last saved settings. If you've previously changed the network name or password, they will remain in effect. However, if this is your first time doing this, the system will use the default values, which are best changed through the full settings menu.
Setting up frequency range and safety standards
shell MIUI Provides the ability to select a frequency range, which is critical for signal speed and range. The 2.4 GHz band is often used by default, providing broad coverage but can be congested by neighboring networks.
For modern devices that support the standard 5 GHz, it's recommended to switch to this frequency. This will allow for significantly higher data transfer rates and reduce interference. However, the range of this network will be shorter, and the signal will have poorer penetration through walls.
In the access point settings menu, find the "Access point frequency band" option. Select 5.0 GHz for maximum performance, or leave it at 2.4 GHz if the connecting device is far away or has an older Wi-Fi module.
| Parameter | 2.4 GHz | 5.0 GHz |
|---|---|---|
| Speed | Average | High |
| Range | High | Average |
| Penetration | Good | Low |
| Workload | High | Low |
You can also configure the number of connected devices in this section. Limiting the number of clients helps conserve battery life and prevent speed drops when the connection is overloaded. Set the limit according to your actual needs.
Managing connected devices and limits
Controlling who exactly uses your internet is an important part of digital hygiene. In the hotspot menu Redmi There's a "Connected Devices" section that displays all active clients. Here you can see the MAC addresses and names of connected devices.
If you notice an unknown device, you can immediately block it. To do this, simply click on the corresponding item in the list and select the block option. This action will terminate the connection and prevent re-authorization from this MAC address.
The system also allows you to set a traffic limit. You can set a data cap, after which the hotspot will automatically shut down. This is a useful feature for preventing unexpected charges if you don't have an unlimited data plan.
What is MAC filtering?
MAC filtering is a network access control method based on unique network interface identifiers. Unlike a password, which can be shared with others, a device's MAC address is more difficult to change. In the Redmi hotspot settings, you can create a whitelist of devices that are allowed to connect, even if they know the password. Other devices will be ignored by the security system.
Regularly checking the list of connected devices will help keep your personal network secure. Don't forget to change your password periodically, especially if you frequently use public spaces or share internet with large groups.
Energy optimization and troubleshooting
Hotspot mode is one of the most power-hungry processes for a smartphone. Active data transfer, high-power radio operation, and constant data packet exchange quickly drain the battery. To extend battery life, it's recommended to connect the phone to a charger.
If you encounter an issue with your access point turning off by itself, check your power saving settings. In some scenarios, the system MIUI may aggressively limit background processes. Add the hotspot service to the battery optimization exceptions.
A common issue is the inability to connect to a second device despite the correct password. In this case, try resetting the radio module: turn the access point off and then back on. Resetting the network settings on the receiving device also helps.
⚠️ Caution: Extended use in tethering mode can cause the smartphone to become significantly hot. If the device becomes hot, take a break or remove the protective case to improve heat dissipation.
To minimize heat, try not to use your phone while tethering for heavy tasks like gaming or video recording. The combined load on the processor and modem creates peak heat output, which can lead to throttling and reduced speed.
Alternative distribution methods: Bluetooth and USB
In addition to classic Wi-Fi, smartphones Redmi Support internet sharing via Bluetooth and USB cable. These methods can be useful in specific situations when the Wi-Fi module is faulty or maximum connection stability is required.
Sharing via a USB cable (USB tethering) provides the most stable connection with minimal latency. This method is ideal for desktop use with a laptop. Simply connect your phone to your computer via a cable and enable the corresponding toggle switch in the "Access Point & Tethering" menu.
A Bluetooth modem offers low data transfer rates but consumes significantly less power. It's a good option for transmitting small amounts of text information or using instant messaging apps when the battery is critically low.
Switching between these modes occurs in the same settings menu. The computer will automatically detect the new network connection and install the necessary drivers if they haven't been installed yet. Bluetooth requires pairing the devices first.
Why doesn't my phone see the access point from Redmi?
Most often, the problem lies in incompatible frequency bands. If the broadcast is on 5 GHz and the receiving device only supports 2.4 GHz, there will be no connection. Try changing the band in the access point settings. Also, check that the network name (SSID) isn't hidden in the privacy settings.
Is it possible to share Wi-Fi if the phone is connected to Wi-Fi?
On most modern models Redmi With Android 10 and above, the "Wi-Fi Repeater" or "Wi-Fi Sharing" feature is available. It allows you to receive internet via Wi-Fi and distribute it further, creating a new network. However, this feature is not available on all models and depends on the version. MIUI.
How do I find out who is connected to my Wi-Fi?
Go to your access point settings and select "Connected devices." This will display a list of all active clients with their names and MAC addresses. If you see an unfamiliar device, change the password immediately and block the offender.
Does Wi-Fi sharing affect mobile internet speed?
Yes, it does. The bandwidth is shared between all connected devices. If several devices are connected to the access point and they're actively consuming data (for example, watching video), the speed on each device will decrease proportionally to the load. The broadcasting process itself also places a slight load on the phone's processor.
