Situations often arise when a laptop or tablet is disconnected from the internet and there's no wired internet connection. In such situations, the hotspot function becomes a real lifesaver, turning your device into a mobile device. router.
The process of creating a coverage area on MIUI-based devices is quite convenient, but it has its own nuances that should be taken into account for stable operation. You won't need third-party apps or complex settings, as all the necessary functionality is built into the system. AndroidAll you need to do is activate the mode correctly and configure the security settings.
In this article, we will take a detailed look at how to share the Internet with Redmi 9, what alternative connection methods exist, and how to optimize data usage. We'll cover the standard Wi-Fi method, as well as lesser-known but useful options for transferring data via USB cable and Bluetooth. Understanding these mechanisms will allow you to effectively manage connections in any environment.
⚠️ Attention: The MIUI interface may vary slightly depending on the firmware version and regional build. If you can't find the menu item, try searching through the settings or updating the software to the latest available version.
Preparing your smartphone for modem mode
Before you start broadcasting a signal, you need to make sure your device is ready for heavy loads. Sharing the internet is a power-intensive process that heavily utilizes communication module and processor. Make sure the battery is charged Redmi 9 is at least 30-40%, otherwise the phone may quickly discharge or go into power saving mode, which will interrupt the connection.
The second critical requirement is an active mobile internet connection. Check that data transfer is enabled in the notification shade and that it is working correctly on the smartphone itself. Without a stable signal from your carrier, 4G/LTE or 3G creating an access point does not make sense.
- 📱 Check your SIM card balance and whether you have an active data plan.
- 🔋 Make sure Power Saving Mode is disabled so that it doesn't block background processes.
- 📡 Make sure that your phone is not in Airplane mode, which blocks all wireless modules.
It's also worth considering security upfront. By default, the system may offer simple passwords or not require them at all, which leaves your network vulnerable. It's best to install a strong one from the start. encryption protocolto prevent third parties from connecting to your channel and wasting your traffic.
Standard Wi-Fi hotspot setup on Redmi 9
The most basic and common way to share the internet is to create a wireless network. To get started, unlock your phone's screen. Redmi 9 and find the "Settings" icon. You're looking for the section usually called "Tethering & Hotspot" or "Connectivity and Sharing." Different versions MIUI The names may vary, but the essence remains the same.
In the menu that opens, select "Wi-Fi Hotspot." You'll see a toggle switch here that you need to enable. However, before you enable it, tap the network name or the "Configure Hotspot" button. This will allow you to change the default device name (e.g., Redmi 9) to something more descriptive and set a strong password.
Please note the frequency range. The system will offer a choice between 2.4 GHz and 5 GHz. Range 5 GHz Provides higher data transfer rates, but has a shorter range and is less effective at penetrating walls. For most scenarios involving devices in close proximity, 5 GHz is the optimal choice if the receiving device supports it.
☑️ Setting up an access point
After saving the settings, turn on the access point toggle switch. Now your Redmi 9 Broadcasts a signal. On another device (laptop or tablet), open the list of available networks, find the name you specified, and enter the password. After a successful connection, a special icon will appear in the phone's status bar indicating the number of connected clients.
⚠️ Attention: When actively distributing Wi-Fi, the phone may become significantly hot. This is a normal physical reaction when the antennas are operating at high power, but try not to cover the device with a cloth or leave it in direct sunlight to prevent overheating of the components.
Alternative distribution methods: USB and Bluetooth
A wireless connection isn't always the best solution. If you need maximum stability and minimal latency (ping), you should consider a wired connection. For this, you'll need the USB cable that comes with your device. Redmi 9Connect your phone to your computer and enable USB tethering in the "Access point & tethering" menu.
The advantage of this method is that the phone simultaneously shares the internet connection and charges from the computer. This solves the problem of rapid battery drain. The computer will recognize the connection as a new network card, and internet access will be available automatically, without the need to enter passwords.
The third option is to use Bluetooth modemThis method is suitable for older laptops or devices with no Wi-Fi and busy USB ports. Data transfer speeds will be significantly lower than over Wi-Fi or USB and are better suited for loading text pages or messaging apps, but not for watching videos.
- 🔌 USB modem provides the most stable connection and no radio interference.
- 🔋 With a wired connection, your smartphone's battery charges, not discharges.
- 📉 Bluetooth connection consumes less energy, but has a low data transfer rate.
To set up a Bluetooth modem, you must first pair it Redmi 9 with the receiving device via the Bluetooth menu. After successful pairing, enable "Bluetooth tethering" in the access point settings. On your computer, select your phone in the Bluetooth settings and click "Connect via" → "Access point."
Why doesn't the computer see the USB modem?
If your computer doesn't respond when you connect the cable, check the cable itself. Some cables are designed for charging only and don't have data lines. Use the original cable that came with the cable or a high-quality, supported replacement. You may also need to install drivers, which Windows usually downloads automatically, but this can be a problem if your PC doesn't have internet access.
Managing connected devices and limits
shell MIUI Provides convenient tools for monitoring who uses your internet. In the access point settings menu, you can see a list of connected devices. This allows you to monitor who is using your network in real time and block unknown users if necessary.
An important feature is setting a traffic limit. You can set the maximum amount of data that can be used via the hotspot. For example, if you have a plan with a 10 GB limit, you can set an 8 GB limit for sharing. Once this limit is reached, Redmi 9 will automatically turn off the hotspot, keeping your main data package.
| Setting parameter | Function Description | Recommended value |
|---|---|---|
| SSID (Network Name) | Name visible to other devices | A unique name without personal information |
| Security | Password encryption type | WPA2 PSK or WPA3 |
| Frequency range | Radio signal frequency | 5 GHz (for speed) or 2.4 GHz (for compatibility) |
| Time-out | Shutdown time when there are no clients | 10 minutes (to save battery) |
A "Whitelist" feature is also available, which allows connections only to pre-approved devices based on their MAC address. This is the highest level of security, ensuring that even with the password, an unauthorized person will not be able to connect to your network. Wi-Fi.
Optimizing traffic and battery consumption
Sharing the internet is a resource-intensive task. To ensure your Redmi 9 To make your phone work longer and more efficiently, it's worth disabling background app refresh on your phone while sharing. Heavy apps can silently consume the data you're sharing, reducing the speed of your primary device.
The smartphone screen is also one of the main energy consumers. If you've set up a hotspot, you can turn off the screen. However, be careful not to let the phone go into deep sleep, as this interrupts the connection. You can add apps you use to exceptions in the battery settings to prevent the system from "killing" the hotspot.
- 📉 Disable photo and cloud syncing while actively sharing.
- 🌙 Reduce screen brightness or use the "Keep screen on while charging" mode if your phone is connected to a PC.
- 🚫 Close heavy apps that consume traffic in the background (navigators, streaming).
Another tip concerns choosing a carrier. If you're in an area with poor coverage, your phone will constantly search for a network, which will drain the battery quickly and cause it to overheat. In such cases, it's best to switch the network mode in the settings (Settings → SIM cards & mobile networks → Preferred network type) on 3G or 2G, if high speed is not required. This will stabilize the connection and conserve battery power.
⚠️ Attention: Mobile carriers' data pricing terms may vary. Some plans may block or charge separately for data tethering (TTL filters). Before actively using the hotspot feature, check your plan's terms in your operator account to avoid unexpected charges.
Troubleshooting connection issues
Sometimes users encounter a situation where the access point is enabled, but the internet on the connected device is not working. A common cause is a network service outage. AndroidIn this case, simply restarting the smartphone or switching to Airplane mode for 10 seconds helps.
Another common issue is an IP address conflict or incorrect DNS settings. On the receiving device (e.g., a laptop), try manually entering DNS servers, such as those from Google (8.8.8.8). Also, make sure that your phone doesn't have data saving mode enabled, which can block background data transfer for other devices.
If devices don't see the network Redmi 9, check if the network name (SSID) is hidden in the privacy settings. It's also worth resetting the network settings on your phone (Settings → Connection and sharing → Reset Wi-Fi, mobile networks, and Bluetooth). This action will not delete your personal data, but will return your network settings to factory defaults.
In rare cases, the problem may lie in the antenna hardware or a software glitch after a firmware update. If all else fails, consider performing a system rollback or contacting a service center, especially if the phone is new.
