A modern Smart TV is no longer a full-fledged media center without access to the global network. Often, there is a situation when your home Wi-Fi router suddenly stops working, the traffic on the tariff runs out, or you are in a rented apartment where access to the router is limited. At such moments, your smartphone becomes the lifeline, especially if it is a device from Xiaomi, which has flexible network configuration capabilities.
Using a mobile phone as a modem is not just a temporary solution, but a complete alternative to wired connectivity for those who value mobility. The MIUI system installed on Xiaomi smartphones has built-in tools to quickly create an access point that are more stable and faster than third-party applications. You don't need to have the skills of a system administrator to set up the distribution of the Internet.
In this article, we will take a look at all the steps of connecting your TV to the network via your smartphone, we will look at standard methods, nuances of working with frequency bands and ways to solve typical problems, you will learn how to manage traffic and protect your data from unauthorized access during a communication session.
The principle of operation of the mobile access point on Xiaomi
Fundamentally, the process of turning a smartphone into a router is called Tethering, or creating a Wi-Fi Hotspot. When you activate this feature, your Xiaomi wireless module switches to receiving a signal from a cell tower (3G, 4G or 5G) and then relaying it to other devices.
It is important to understand that with such a connection, the smartphone creates a local network, assigning an internal TV to the connected TV. IP-All traffic is through a mobile connection, which imposes certain limits on the speed and volume of data consumed. MIUI undertakes the tasks of routing data packets, ensuring stable exchange of information between TV and the Internet.
Current models of Xiaomi phones support two bands: 2.4 GHz and 5 GHz. The choice of range affects the range of the signal and its penetrating capacity, as well as the maximum data rate. For a TV that is usually in the same room with the phone, it is preferable to use a higher speed range if it is supported by both devices.
- 📡 The smartphone acts as a gateway between the cellular network and the local network of the TV.
- ⚡ Activation of the function occurs at the level of system services of the Android kernel.
- 🔒 Encryption of the connection is carried out by protocols WPA2 or WPA3.
⚠️ Attention: With an active access point, the phone consumes significantly more power and can get very hot.
It is worth noting that some carriers may limit the speed or block the distribution of traffic to third-party devices, if not provided for by your plan. In such cases, the TV may connect to the network, but the pages in the browser or applications will not load.
Preparation of the smartphone and checking the settings
Before trying to connect your TV to the Internet, make sure your Xiaomi is ready to run in modem mode. SIM-maps and signal level of the cellular network. For comfortable viewing of video in high resolution, it is recommended to have a stable signal. 4G (LTE) higher.
Go to your mobile Internet settings and make sure that the data is activated. Try opening any page in your browser or running a video in your app to make sure that the Internet is running directly on your phone. Without a working mobile connection, it is technically impossible to distribute the Internet to your TV.
Streaming services consume a lot of data: one hour of watching Full HD video can eat up to 3 GB of traffic. If you have a limited rate, it is better to set limits in advance or monitor the flow to avoid unexpected write-offs.
Remember to charge your smartphone battery to at least 50-60%. Access point mode is one of the most energy-intensive processes in the MIUI system. If the phone runs out during setup or viewing, you will have to start the connection procedure again, which can take time.
- 🔋 Charge your smartphone battery to at least 60% before a long session.
- 📶 Make sure the badge 4G/LTE displayed in the status bar stably.
- 💰 Check the remaining gigabytes through the operator’s app or USSD-team.
In some regions or some firmware, you may need to manually configure access points. APN. They usually come automatically with operator settings, but if the internet doesn’t work, go to the mobile networking section and check if the correct profile is selected for your mobile network. SIM-This is a critical parameter for getting online.
Step-by-step instruction for activating the access point
The process of enabling modem modem on Xiaomi devices is standardized, but the location of menu items may vary slightly depending on the version of the MIUI shell. The algorithm of actions is the same for most models, from budget Redmi to flagship Mi and Xiaomi.
Open the main settings menu for your smartphone. Find a section that is usually called Wi-Fi Access Point or Connect and Share. In newer versions of the interface, this item is often displayed in a separate menu, "More" or "Additional Features", if it is not placed on the main settings screen.
☑️ Pre-launch checks
Inside the hotspot settings menu, you need to set a network name (SSID) and password. The network name is how your TV will "see" the phone in the list of available connections. The password should be complex enough that neighbors can't connect to your Internet, but convenient for entering from the TV remote.
Settings -> Wi-Fi Access Point -> Setting up the access pointOnce you have set the settings, just turn the Wi-Fi hotspot switch into the active position, and the screen of your smartphone may go out or a special icon in the top panel will appear to indicate that the Internet distribution is running, and the phone is now visible for search by external devices.
- 📱 Open “Settings” on the home screen or in the notification curtain.
- 📶 Go to the section "Wi-Fi hotspot).
- 🔐 Set a strong password and set a clear network name.
⚠️ Warning: Do not use special characters in your network name or password if your TV is an old model. TV Badly recognize signs like “@”, “#” or gaps in the network name.
Frequency range and security setting
One key point that users often ignore is the choice of frequency range. The access point settings menu on Xiaomi often has the option of choosing between 2.4 GHz and 5 GHz. Older TVs may simply “not see” the network if it is running at 5 GHz, since their Wi-Fi modules only support the 2.4 GHz standard.
If you’re not sure about your TV’s performance, start with a 2.4GHz band that offers better compatibility and longer range, albeit slower speeds. If your TV supports the current 802.11ac standard, switching to 5GHz will give you a more stable picture when watching 4K content.
When it comes to security, it’s important to choose the right encryption protocol. In the access point settings, look for “Security” or “Security Type.” It’s recommended to choose WPA2 PSK or WPA3 PSK. WEP protocols or open networks provide no protection, allowing attackers to intercept data that your TV is transmitting.
| Parameter | 2.4 GHz | 5 GHz |
|---|---|---|
| Transmission speed | Up to 150-300 Mbps | Up to 800+ Mbps |
| Range of action | High (up to 50 m) | Medium (up to 20 m) |
| Penetrability | Good (over walls) | Low (walls muffling) |
| Compatibility | All devices. | Only new devices. |
You can also set a limit on the number of devices you can connect to your security settings, set a "1" to allow only your TV to connect to your access point, and this will prevent other gadgets in the house from accidentally connecting, which can start downloading updates and slowing down viewing.
Why 5GHz is better for video?
The process of connecting the TV to the network
Once the hotspot on Xiaomi is activated, go to the setup of the TV itself. Take the remote control and log into the main menu of your Smart platform (be it Android TV, Tizen, WebOS or the manufacturer's own shell).
Select the Wireless or Wi-Fi connection type. The TV will start scanning the surrounding space. In a few seconds, the name you set on the phone should appear in the list of available networks, select it and press the confirmation button (usually OK or the center button).
A virtual keyboard will appear on the screen. Enter the password you set in the access point settings. Be careful when you type: the register of letters has a value, and the characters on the TV keyboard can be arranged outside the box. After you type in, select Connect or Ready.
- 📺 Go to the TV menu and select the "Network" section».
- 🔍 Find the name of your access point in the list (SSID).
- ⌨️ Enter the password and wait for the message "Connected».
If the connection is successful, the TV usually shows the status of "Connected" and signal level. Often the system automatically runs a test of Internet connection speed, if the test is passed, you can run YouTube, Netflix or other applications to check the quality of the stream.
⚠️ Warning: If the TV writes “Connection Error” or “Incorrect Password”, try forgetting the network on the TV and creating the access point again with a new simple password (numbers only).
Solution and optimization of speed
Even if you set it up properly, you can have problems. The most common one is that the TV sees the network but it doesn't connect, or the connection is there, but the Internet doesn't work. First of all, try rebooting the Wi-Fi module on your phone: turn off the hotspot and turn it on again. IP-Addresses and resets temporary errors.
Another common problem is slow speed, which can be caused by a weak signal from the cellular network, try moving the phone closer to the window or lifting it higher, and also make sure there are no massive metal objects between the phone and the TV that shield the signal.
💡
For maximum stability, place your phone down next to the TV, but not on it, to avoid overheating from the heat of the panel.
If nothing helps, try to change. APN. Go to the mobile network settings, select your SIM-map, then “Access points (APN)». Click the menu (three dots) and select Reset to defaults. Sometimes operators change server settings, and the old profile stops working correctly with the handout function.
In some cases, change helps. MAC-On Android TVs. TV You can try to change it. MAC-Wi-Fi address in the extended network settings on "Random" or vice versa, on MAC-This helps bypass some of the restrictions on the part of the ISP or router if they block unknown devices.
- 🔄 Restart both devices: the phone and the TV.
- 📶 Check if the phone is “traffic saving».
- ⚙️ Reset the network settings on the TV to factory.
Remember that image quality is directly dependent on the stability of the 4G signal. If the signal jumps, the video will constantly stop for buffering, in such cases it is better to reduce the quality of playback in the application (for example, from 4K to 1080p) to ensure smooth viewing.
💡
The stability of the connection depends not only on the phone settings, but also on the physical location of the devices and the signal level of the cell tower.
