Modern Xiaomi and Redmi smartphones have long since ceased to be mere calling devices, becoming powerful tools for work and entertainment. Situations often arise when a desktop router is unavailable, but internet access on a tablet or laptop is vital. It's in these moments that the "Internet" feature mobile hotspot becomes a lifesaver, allowing you to instantly share traffic with other gadgets.
The MIUI interface on Redmi devices offers numerous hidden features and settings that aren't always immediately obvious. Properly configuring tethering will not only ensure a stable connection but also significantly save your device's battery. In this article, we'll cover all the details, from basic setup to advanced security settings.
Xiaomi device owners often face the issue of optimizing power consumption when the communication module is actively operating. Android system can aggressively close background processes, leading to connection drops if you don't set the appropriate priorities. Understanding these mechanisms will allow you to use your smartphone as a fully functional device. mobile router without the risk of sudden client disconnection.
Before setting up, make sure your device has mobile data enabled or is connected to a different Wi-Fi network that you plan to relay. It's also a good idea to check your current data balance if you're not on an unlimited plan to avoid unexpected charges. Now let's move on to activating the feature.
Basic activation of the access point via the curtain
The fastest way to enable tethering is to use the control panel, accessible by swiping down from the top. In most cases, the system will automatically select the optimal settings, but for initial setup, it's best to browse the menu. Find the icon labeled Access point or Hotspot and tap on it to turn it on.
If the icon is inactive or grayed out, your mobile data may be disabled or airplane mode may be on. Some firmware versions require you to press and hold the icon to access advanced settings, where you can change the network name and password. This action will open a menu. Settings → Wi-Fi Hotspot.
It's important to understand that the default system-generated password may be difficult to remember, but it provides basic security. You can change it to something more convenient, but it's not recommended to leave the network open without a password. This will protect your data from unauthorized access in public places.
Deep configuration of network settings in the menu
For more detailed settings, go to the section Settings, then select the item Connection and sharingThe menu is located here. Wi-Fi hotspot, where all the necessary settings for personalizing your network are available. This is where you can change the default device name (e.g., Redmi Note 10) to something more descriptive.
Particular attention should be paid to the frequency range. Modern Redmi models support two bands: 2.4 GHz and 5 GHz. The 5 GHz band provides higher data transfer speeds, but has a shorter range and is less able to penetrate walls. The 2.4 GHz band is more versatile and compatible with older devices.
⚠️ Important: When selecting the 5 GHz band, make sure the devices you're connecting to (laptop, tablet) support this standard. Older devices may simply not see your network in the list of available connections.
This menu also offers a feature for limiting the number of connected devices. You can set a limit of, for example, 3 or 5 clients to control the load on your smartphone's processor and data usage. This is especially useful if you're in a crowded area and want to avoid unauthorized connections.
☑️ Check before switching on
Selecting a security and encryption protocol
Data security is a critical aspect when setting up a wireless network. Redmi hotspot settings usually prompt you to select a security protocol from a list of available options. The most modern and reliable standard currently available is WPA3-Personal, which provides maximum protection against hacking.
However, if your clients include devices running outdated software, they may not support new encryption protocols. In this case, you should choose WPA2-Personal, which has been the gold standard for compatibility and security for many years. Using an open network or the WEP protocol is strictly not recommended.
When changing the security type, the system may require you to re-enter your password or warn you about a temporary connection loss. This is normal behavior, as the handshake algorithms between devices are changing. Always set a complex password containing mixed-case letters and numbers to make it more difficult to guess the key.
Why can't I set up open Wi-Fi?
An open network allows any attacker within range to intercept your traffic. This can lead to the theft of website passwords, personal photos, and correspondence. Always use WPA2 or WPA3 encryption.
Energy saving and sleep timer
Sharing Wi-Fi is a power-hungry process that quickly drains your smartphone's battery. To prevent the battery from draining completely at the wrong time, Redmi has implemented a smart sleep timer. It allows you to configure the hotspot to automatically turn off if no one is connected to it for a long time.
Find the parameter Turn off the access point in the settings menu and select a time interval, such as 10 minutes. If no devices connect to your network within this time, or all clients are disconnected, the Wi-Fi module will go into sleep mode. This will help conserve battery power for important calls or navigation.
Additionally, it's worth disabling power saving mode for the hotspot process itself, if it's available in your MIUI version. Sometimes the system may mistakenly consider an active hotspot as a background process that needs to be limited. Check your battery settings and ensure there are no hard limits on the hotspot service.
Frequency Band Comparison: 2.4 GHz vs. 5 GHz
Choosing the right frequency directly impacts connection speed and stability. To help you decide on the right settings, we've prepared a comparison chart of the characteristics of both bands. This will help you choose the best option based on your current needs and environment.
| Characteristic | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Transfer speed | Average, up to 150 Mbps | High, up to 800+ Mbps |
| Range | Large, better at avoiding obstacles | Smaller, sensitive to walls |
| Workload | High (many neighboring networks) | Low (less interference) |
| Compatibility | Works with all devices | Requires 5 GHz support |
If you live in an apartment building, the 2.4 GHz band can be heavily polluted by neighboring signals. In this case, switching to 5 GHz will provide a noticeable speed boost, even if you're not right next to your smartphone. However, for simple tasks like checking email, the difference may not be as noticeable.
For online gaming and 4K video viewing, 5 GHz is preferable due to its lower ping and higher throughput. If you need to share the internet with a smart light bulb or an old printer, choose 2.4 GHz for guaranteed compatibility.
Solution: If the access point does not work
Sometimes users encounter a situation where the hotspot is enabled, but other devices can't connect or don't see the network. The first step is to try restarting your smartphone—this is a classic tip that resolves 90% of software issues with communication modules. Android.
Check if you have a traffic limit set in your hotspot settings. If you previously set a limit, for example, 1 GB, and the limit is reached, sharing will automatically stop. Reset the statistics or increase the limit in the corresponding settings menu.
⚠️ Note: The settings interface may differ depending on the MIUI version (12, 13, 14) and regional ROM (Global, China, EU). If you can't find the item, try searching for "Hotspot" in the settings.
The problem may also be related to a static IP address. Ensure that the access point's DHCP server settings are not incorrect. In most cases, selecting automatic IP configuration is sufficient, allowing the system to automatically distribute addresses among clients.
