Modern smartphones have long ceased to be just devices for calls, becoming full-fledged mobile routers that can provide access to the network laptops, tablets and other gadgets. Owners of Xiaomi and Redmi devices often face the need to quickly distribute Wi-Fi, while on the road or in the area without wired Internet. The function of the access point in the shell of MIUI is implemented conveniently, but has a number of hidden settings that not all users know.
In this article, we will discuss in detail the process of activating modem mode, configuring connection security and optimizing power consumption for long-term work. You will learn how to avoid typical errors when connecting third-party devices and what parameters should be changed for a stable data transfer rate. Competent setting will allow you to use your phone as a full-fledged source of Internet without the risk of quickly draining the battery or exhausting traffic.
We will focus on the nuances of operating with different frequency bands and the limitations that your mobile operator can set, and understanding these aspects is critical for those who use a smartphone as their primary channel for work or study, followed by detailed instructions that will help you adjust all the parameters in a few minutes.
Activate the access point through quick settings
The fastest way to start the distribution of the Internet on Xiaomi smartphones is to use the control panel. You just need to unlock the screen and swipe from top to bottom to open the notification curtain. Among the shortcuts, you need to find an icon that says "Access Point" or an antenna image.
If the standard icon is not on the first screen, press the edit button (usually a pencil or three dots in the corner) and drag the desired module into the active zone. Once the icon is turned on, the icon will light up, indicating a successful launch of the service. However, this method activates the distribution with factory parameters that may not be safe.
To change your network name or password, you need to go to the advanced settings. Press and hold your finger on the activated access point icon in the notification curtain. This action automatically takes you to the Settings menu → Wi-Fi Access Point, where you can change the network SSID and set a strong password.
Important: By default, the system often suggests using WPA2 PSK, but older devices may need to choose a compatible mode.Don't leave the network open, as any nearby user will be able to connect to your traffic.
☑️ Checking before handout launch
Configure network and security settings in MIUI
Deep access point settings allow you to tailor your smartphone to specific tasks. In the Settings menu → Wi-Fi Access Point → Adjustment of the access point allows you to access key parameters. Here you can change not only the network name (SSID), but also select the frequency range.
The 2.4 GHz range provides better compatibility with older devices and longer coverage distance, but the speed is lower here.The 5 GHz range gives you a high data rate, however, the signal range will be smaller, and many older laptops may just not see the network. The choice depends on which device you plan to connect.
Special attention should be paid to the “Hide the Network” option, which if you activate this feature, your device will not broadcast the network name on the air. To connect, other users will have to manually enter the SSID and password, which significantly improves security, but reduces the usability among friends.
⚠️ Note: when choosing a 5GHz band, make sure that the connected devices support this standard. Otherwise, the phone will be visible, but you will not be able to connect to it, which often confuses users.
Also in this section you can set a limit of connected users. Limiting the number of devices (for example, to 3-4 pieces) will help prevent unauthorized access and reduce the load on the smartphone processor, which will positively affect battery life.
💡
Use the 5GHz band only for large files or video streaming. For instant messengers and documents, you should choose 2.4GHz to save charge.
Use of the USB-modem and Bluetooth panel**
It is not always convenient or possible to use Wi-Fi to distribute the Internet, and alternative methods are available on Redmi and Xiaomi smartphones: USB-Modem and Bluetooth panels, which are often ignored but can be a lifeline in critical situations.
USB-The modem allows you to transfer the Internet from phone to computer via cable, it provides a stable connection without loss of speed and at the same time charges the battery of the smartphone. → Wi-Fi hotspot → USB-modem and activate the switch.
The computer automatically recognizes a new network connection, ideal for stationary jobs where maximum speed and minimum latency are important, and USB cannot be used as a neighbor because physical contact is required.
The Bluetooth panel is slower but consumes significantly less power than the Wi-Fi module. Turn on Bluetooth on both devices, pair, and then select a Bluetooth modem from the access point menu on the phone. On the computer in Bluetooth settings, you need to select your phone and click “Connect through» → «Access point».
| Parameter | Wi-Fi Access Point | USB-modem | Bluetooth modem |
|---|---|---|---|
| Speed. | High (up to 150 Mbps) | Maximum (depending on the network) | Low (up to 2-3 Mbps) |
| Battery consumption | High-pitched | Charging the phone | Low. |
| Range. | Up to 15 meters. | Cable length | Up to 10 meters. |
| Number of devices | 10. | 1 | 1 |
Traffic and data limits management
Uncontrolled Internet distribution can lead to a rapid exhaustion of the tariff plan. MIUI provides built-in tools to monitor and restrict traffic. In the access point menu, find the item "Limit traffic" or "Limit traffic".
You can set a data limit here, and then you can automatically shut down the distribution, which is a useful feature for those who are not on unlimited rates or are roaming, and it will alert you when 80 percent and 100 percent of the limit are spent.
Also worth paying attention to the One-Time Access Point feature, which, when turned on after the last connected device is turned off, the Internet distribution will stop automatically after a specified period of time, which prevents situations where you forgot to turn off the hotspot, and the phone wastes charge and traffic.
Usage statistics show how many megabytes were transferred through an access point, and checking this indicator regularly helps to identify “voracious” applications on connected devices or unauthorized access.
What to do if the limit does not work?
Solution: The phone doesn't give away the internet or see the network**
Despite Xiaomi's stability, users may face problems, and one of the most common is that devices see the network but can't connect, giving an error: "Failed to get a hold of the network." IP-This is most often solved by changing the type of encryption.
Try changing the protocol from WPA2 PSK to WPA PSK or vice versa in the security settings (Security), some old network cards conflict with modern encryption standards, and resetting the access point to the factory also helps.
Another problem is that the connected device has Internet, but the pages don't load, so check if the data transfer is on on the smartphone itself, and sometimes after you upgrade or reboot the dataset, it can turn off and the access point is running idle.
If the problem persists, try turning off power saving for system processes. Aggressive MIUI optimization can kill the Wi-Fi distribution process to save charge. Go to Settings → Battery → Settings and turn off super-saving mode.
⚠️ Warning: Some mobile operators are blocking or slowing down the distribution of the Internet (Tethering), determining the TTL In such cases, standard methods may not work without the use of special applications or root rights, which requires separate technical training.
Optimizing the work to save the battery**
Access point mode is one of the most energy-intensive processes in a smartphone. Wi-Fi is running at high power, and the processor is actively processing network requests. To keep your phone from running out in an hour, follow simple optimization rules.
First, turn the screen down or turn off the display after the handoff is triggered. The screen is the main power consumer, and it does not make sense to run in standby mode with an active hotspot. Second, close the background applications that can consume traffic (email updates, photo sync).
Use the original cable and power supply if you are working over USB. Unstable voltage can lead to constant reconnections, which even faster puts the battery down. In the battery settings, you can turn on "No Limits" mode for system processes associated with the network so that the system does not artificially try to limit speed for the sake of saving.
Critical: If you run in router mode for a long time, your smartphone can get very hot. Remove the case if it's dense, and put the device on a hard surface for better heat sink. Overheating leads to trottling (decreased performance) and accelerated battery wear.
💡
Reducing the screen brightness to a minimum and turning off background synchronization can extend the access point’s operating time by 30-40%.
