Redmi or PocoHowever, the system's operating logic remains consistent across the entire ecosystem, allowing the methods described below to be used on most current devices. Before beginning the procedure, ensure that your data plan is enabled and has sufficient traffic.
Preparing your smartphone and checking your mobile internet connection
Before setting up the hotspot, you need to make sure your primary data connection is working properly, as this is the mobile internet that will be broadcast to other devices. Open the notification shade and check if the icon is lit. 4G or 5G next to the cellular network signal indicator. If the icon is missing or grayed out, there may be a problem with the SIM card or carrier network settings.
It's recommended to first open any browser and load a test page to confirm an active connection. This will rule out situations where the hotspot is working but the connected laptop has no internet access due to blocking by the provider. It's also worth checking your account balance, as some providers automatically suspend access when your balance is zero.
⚠️ Attention: Before actively tethering, be sure to check the terms of your plan with your mobile operator. Many plans limit the amount of data you can tether or require a separate fee for using your smartphone as a modem.
Make sure the wireless module is enabled on your device, even if you only plan to use it for outgoing connections. In some cases, the system may require activation. GPS or other geolocation services to correctly determine the network type, although this is rarely necessary for basic data sharing. Checking these parameters takes less than a minute and will save time on future troubleshooting.
Step-by-step instructions: enabling hotspot on Xiaomi
To activate the modem mode on smartphones Xiaomi There are several ways, from the quick menu to deep system settings. The fastest method is to use the control panel: swipe down from the top to open the control center and find the icon Access pointClicking on it will activate the feature, but will not allow you to change security settings or the network name.
A more reliable method is to use the settings menu, where all the necessary parameters for configuring the connection are available. Go to the section Settings, then select the item Wi-Fi hotspot, which is usually located in the Connections or Portable Devices settings group. In the menu that opens, click the switch Turn on Wi-Fi hotspot, after which the smartphone will start broadcasting the signal.
☑️ Check before switching on
Once enabled, a notification will appear on your smartphone's screen, and a green icon will light up in the status bar. You can now search for the created network in the list of available connections on your laptop. The default network name usually includes the device model, for example, Mi 11 or Redmi Note 12, but it can be easily changed in the settings.
Setting up security and network settings
The default settings offered by the system may not provide sufficient security or optimal connection speed. To change the settings, tap on Setting up an access pointHere you can set a new network name (SSID) that will be displayed when searching on other devices.
A critical element is the selection of a security protocol and the setting of a complex password. It is recommended to use the standard WPA2 PSK or WPA3If your devices support this standard, they provide encryption of transmitted data. The password must contain at least 8 characters, including upper- and lower-case letters and numbers, to prevent guessing.
| Parameter | Recommended value | Description of impact on work |
|---|---|---|
| Frequency range | 5 GHz (if supported) | High speed, less interference, but shorter range |
| Security protocol | WPA2/WPA3 Personal | Maximum protection against password hacking |
| Shutdown timeout | 10 minutes / Do not turn off | Saves battery when no clients are connected |
| Maximum connections | 1-3 devices | Limit the number of users to maintain speed |
This menu also allows you to set an automatic shutdown timer. If no one connects to the hotspot within the specified time, the smartphone will automatically turn off the tethering module to save battery life. This is a useful option if you tend to forget to turn off tethering after use.
Selectable frequency range: 2.4 GHz or 5 GHz
One of the key settings that affects connection speed and stability is the frequency band selection. In the access point settings menu, find the option Access point frequency rangeBy default, the system can select a range automatically or use the standard 2.4 GHz, which is compatible with all devices.
Range 2.4 GHz It has a longer range and penetrates walls better, but it's often overloaded with signals from nearby routers, microwave ovens, and Bluetooth devices. This can lead to unstable ping and reduced speed, which is especially noticeable during video calls or online gaming on a connected laptop.
⚠️ Attention: When switching to the 5 GHz frequency, older laptops or tablets may no longer see your network. Make sure the receiving device's network adapter supports the standard. 802.11ac or newer.
Range 5 GHz provides significantly higher data transfer speeds and operates in less noisy airwaves. If your laptop and smartphone Xiaomi If the phones are in close proximity to each other, choosing this band will allow for maximum mobile internet performance. However, the signal range will be shorter in this case.
Why is 5GHz faster?
The 5 GHz band uses wider data transmission channels and has more free frequencies, which allows more information to be transmitted per unit of time without collisions with other devices.
Connecting a laptop to a Xiaomi network
Once the hotspot on your smartphone is activated and configured, you need to connect to it on your laptop. Open the list of available Wi-Fi networks on your computer, usually by clicking the wireless network icon in the system tray (Windows) or the menu at the top (macOS). Find the name you specified on your smartphone in the list.
Click the button Connect and enter the previously set password. Please be careful when entering: the system is case-sensitive, so spelling errors will result in access being denied. After successful authorization, the connection status will change to "Connected," and a notification indicating the number of active clients will appear in the phone's status bar.
If your laptop isn't detecting the network, try refreshing the list of available connections or moving the devices closer together. It's also worth checking that Airplane Mode isn't enabled on your laptop, which blocks all wireless interfaces. In rare cases, restarting the computer's network adapter can help.
Advanced features: traffic limitation and whitelist
shell MIUI provides users with advanced tools for managing connected clients, which is especially useful when using public transportation or in crowded areas. In the access point menu, you can find a section Connected devices, which displays all the gadgets that are currently using your Internet.
Function Whitelist Allows connections only to specific devices whose MAC addresses are included in the database. This is the most secure method of protection: even if someone learns your password, they won't be able to connect because their device isn't authorized. To add a device, you need to know its MAC address, which can be found in the network properties of the device you're connecting to.
A traffic limitation option is also available, allowing you to set a data limit for tethering. You can set a maximum amount, such as 1 GB, after which the hotspot will automatically turn off. This prevents unexpected data consumption and helps you manage your mobile phone costs.
Solution: The laptop does not see the network or there is no Internet.
Despite the ease of setup, users may encounter a situation where the laptop detects the network, but the internet connection doesn't work, or the network is completely absent from the list. One common cause is incompatibility of security standards or frequency bands, as discussed above. Try temporarily switching the band to 2.4 GHz and changing the encryption protocol to WPA2.
Another common problem is the mobile operator's blocking of data sharing. Some providers block or slow down connections when they detect data sharing, using analysis. TTL (Time To Live) packets. In such cases, standard phone configuration methods won't solve the problem; changing the TTL at the system level or using specialized apps is required.
⚠️ Attention: The settings interface and menu item names may change with shell updates. HyperOS or MIUIIf you can't find the item described, use the search in your phone settings by entering the keyword "Hot Spot" or "Modem."
If the issue persists, reset the network settings on your smartphone or restart both devices. Sometimes deleting the saved network on your laptop ("Forget the network") and re-establishing the connection from scratch helps. Also, make sure that power-saving modes aren't enabled on your phone, as these can aggressively limit background processes and communication modules.
What is TTL and how does it affect?
TTL is a data packet parameter that decreases by one each time it passes through the router. The operator sees the decrease in value and understands that you're sharing internet.
