Modern Smart TV from Xiaomi (Mi) TV, Redmi TV) These are powerful multimedia centers, but their functionality depends on the quality and stability of the Internet connection. In situations where wired Ethernet is not available, and the Wi-Fi signal is too weak or unstable, users often think about direct connection. USB-This seems logical, but it faces the software limitations of the Android operating system. TV, which does not always have built-in drivers for recognizing mobile networks.
Before we start to physically connect devices, we need to understand the architecture of the connection. 4G-modem USB-Xiaomi TV port in 90% of cases will not work without root-rights or special firmware, as the system does not automatically switch to mobile Internet via the Internet. USB-But there are effective workarounds that allow you to distribute the Internet to your TV using a modem as a signal source. In this article, we'll look at all the working methods, from setting up a router to software crutches.
The main problem is that the TV perceives USB-The port is primarily a storage for media files. Network hardware requires PPPoE protocol support or specific drivers in the core. Most standard Mi Box S models or diagonal TVs. 43-55 Inches don't have this functionality out of the box. So our challenge is to create an environment where the TV gets the Internet without requiring it to work directly with the modem at the hardware level.
Compatibility analysis USB-modems and ports of television
The first step is to check the hardware. USB-The modem is suitable for interaction with the Xiaomi ecosystem. TVs run on the basis of Amlogic or MediaTek processors, which have a limited set of supported modem vendors. Most often, out of the box or with minimal configuration, devices from Huawei are determined, ZTE and some of the Alcatel models.
It is important to consider energy consumption. USB-The TV port usually gives a current of 0.5 Ampere (less often than 1A), which may not be enough for full operation. 4G-modem, especially when searching for a network or transmitting large amounts of data, in which case the device may be constantly restarted or simply not detected by the system. USB-feed-in.
The list of the most compatible modem models that have a chance to earn (often require a switch to modem modem):
- 📡 Huawei E3372 (A popular model often requires switching modes)
- 📡 ZTE MF833V (Supports HiLink mode, which makes it easier to set up)
- 📡 Alcatel Link E5377 (A mobile router that can be used as an adapter)
- 📡 AnyDATA (Rare Models That Require Driver Checking)
⚠️ Note: Attempt to connect a modem that requires installing drivers with CD-disc (virtual) CD-ROM inside the modem, to a TV without a computer is doomed to failure.
You should also pay attention to the version. USB-The back of Xiaomi TV often has ports. USB 2.0 and USB 3.0. For modems, it is preferable to use the port USB 2.0 (usually white) as it provides better peripheral compatibility and less power consumption in standby mode.The blue port (3.0) is better reserved for hard drives or flash drives with movies.
Method 1: Using a router as an intermediary (The most reliable)
The most stable and professional way to connect a modem to a Xiaomi TV is to use an intermediate link – a Wi-Fi router or a mobile phone. 4G-In this scheme, modem only works with the router, and the TV receives a ready-made, stable Internet channel via Wi-Fi or cable. LAN. This takes the load off the TV's processor and eliminates driver problems.
To implement this method, you will need any router with support. USB-modems (e.g. models from Keenetic, TP-Link, Asus or MikroTik) The setup procedure is as follows: you insert SIM-map to modem, modem connect to USB-router port.Next, via the router's web interface (usually available at 192.168.0.1 or 192.168.1.1), you activate the mode of operation. USB-modem.
☑️ Setting up the Router-Modem bundle
Once the router has successfully connected to the operator's network, it creates a local network. Xiaomi TV in this case connects to the router in the standard way: through Wi-Fi settings or via Ethernet cable. The benefits of this approach are obvious: the router takes over all negotiations with the cell tower, automatically reconnects when communication breaks down and distributes the Internet to all devices in the house.
If you do not have a separate router, but have an Android smartphone, you can use it as a router. USB-A modem for a router (if the router supports tethering) or distribute Wi-Fi directly to the TV. However, the phone's charge consumption will be high, and connection stability may suffer with incoming calls.
Method 2: Direct Connection and HiLink Mode
There is a class of modems that operate in HiLink (or Stick Mode) mode, in which a modem, when connected to any device (computer, TV), immediately creates its own Wi-Fi network or virtual network interface without requiring the installation of drivers, the TV sees it as a regular wired network (Ethernet over USB) or as a Wi-Fi point.
If your modem supports HiLink mode, the algorithm of actions is simplified. USB-The port of the Xiaomi TV. Android system TV can identify him as"USB Ethernet" or network adapter. in this case in network settings (Settings → Network and Internet: A new type of connection that can be activated.
However, if the modem is defined as a drive (flash drive) rather than a network device, it will be necessary to switch its mode. On the computer this is done through the modem web interface (address often 192.168.8.1), where in the settings you need to select "Modem Mode" or disable "Drive Mode".
What to do if HiLink mode is not turned on?
It is worth noting that even if a modem is successfully identified as a network card, the TV may not know how to handle the PPPoE connection that is often required to access the Internet (login and password from the provider).
Software Solutions: PPPoE Setup and Third Party Applications
If the modem is determined, but the Internet has not appeared, most likely, authorization is required. Mobile operators rarely require login and password (authentication is used by the username). IMSI SIM cards, but some corporate rates or home internet via 4G-Gateways may require PPPoE settings.
In the standard interface Xiaomi TV (MIUI for TV) There is no menu for entering PPPoE data when connecting via USB. Here to help third-party applications from the Google Play store or installed through the APK-One of the popular solutions is the application. PPP Widget (requires root rights) or various"USB Modem Dialer".
To install such applications, you will need:
- 📱 The flash drive APK-file of the desired application (for example, the X-Plore file manager and the dialer distribution)
- 🔓 Superuser rights (Root) obtained through ADB orthologies
- ⚙️ Included debugging by USB Settings menu → About the device → Assembly (7 times)
Without root rights, there's limited options. You can try installing an app. USB Camera (paradoxically, but sometimes helps to skip the net) or specialized launchers, but success is not guaranteed. ADB-commands to force the network interface to be enabled if the modem driver is still loaded.
adb shell netcfg
adb shell ifconfig usb0 up
adb shell dhcpd usb0These commands are entered from a computer connected to the same network as the TV (or over the phone). USB-Male-to-male cables, if the TV supports ADB through USB). The netcfg command will show you a list of interfaces. usb0 or eth0 condition DOWN, But again, without a deep knowledge of Linux, it can be difficult.
Table of comparison of connection methods
To make it easier for you to choose the best option, we have prepared a summary table that compares the methods considered by key parameters, which will help you to weigh the pros and cons before buying equipment.
| Parameter | Through router (Recommended) | Direct USB (HiLink) | Direct USB (Normal Mode) | Smartphone as modem |
|---|---|---|---|---|
| Stability | Tall. | Medium | Low. | Medium |
| Difficulty setting up | Low. | Medium | Tall. | Low. |
| The need for a Root | No. | No (most often) | Yeah (almost always) | No. |
| TV resource expenditure | Minimum | Medium. | High-pitched | Low. |
Solving Connection Problems and Errors
Even if you follow all the instructions, you can have a problem, and one of the problems that is common is that the TV sees the modem as a flash drive and tries to scan it for photos and videos, and then the notifications might have a "File system is damaged" error, or just a gallery opens, and the solution is to switch the modem to "Modem Only" modem via the computer.
Another problem is the weak signal. The TV is usually far from the window, and the device body (especially if it is metal or on a metal cabinet) can shield the signal.
💡
Use it. USB-Extension cord, connect the modem through a short USB-extensioner (0.5 - 1 You can take his antenna out to the open, closer to the window. 2-3 once.
If the Internet is available, but it is slow (video slows down, quality drops), check the settings. DNS. In the settings of the Xiaomi TV network, you can prescribe static DNS-Addresses such as those from Google (8.8.8.8) or Cloudflare (1.1.1.1) often speed up interface response and application launches.
⚠️ Note: If the TV stops seeing the network after connecting the modem, try to disable the Auto Switch to Mobile Network function in the TV settings (if there is one in your firmware version) to avoid interface conflicts.
Speed optimization and DNS setup
Once connected successfully, it is important to ensure a comfortable speed for streaming in 4K. Mobile Internet is prone to pings and packet losses. To minimize buffering in applications like YouTube, Netflix or ivi, it is recommended to change the DNS settings directly on the TV.
Go to Settings. → Network and Internet → Network. Select your connection (Wi-Fi or Ethernet). IP Select "Static" (or "Manual"). IP-address and gateway (if already registered by the router), find the fields DNS 1 and DNS 2.
Recommended values for fast work:
- 🚀 DNS 1: 8.8.8.8 (Google)
- 🚀 DNS 2: 1.1.1.1 (Cloudflare)
- 🚀 Alternative: 77.88.8.8 (Yandex - may be faster in Russia)
It’s also worth checking if the modem (if possible through its web interface) has a speed limit or traffic savings on it. If you are using a Keenetic router, it has a Game Priority or QoS function where you can prioritize your router. MAC-TV addresses, which will allocate more channel resources for it.
💡
Use of static DNS-Servers are the easiest way to speed up Smart response TV and eliminate application download errors when using the mobile Internet.
