If you are a lucky owner of a Xiaomi Mi TV TV Or the Redmi Smart series. TV, I probably noticed on the back of a small plastic connector with the inscription LAN. This port, despite its modest size, plays a key role in ensuring a stable Internet connection – especially if you like watching movies in the Internet. 4K, Playing online games or using Smart TV-But what is it really about, and why is it that the manufacturer didn't just limit itself to Wi-Fi?
In this article, we will explain why you need LAN-The connector in the Xiaomi TV, how to connect it correctly (including the choice of cable and router), what settings optimize the network, and what to do if the Internet through the cable does not work. LAN Wi-Fi and which cable to choose at the same time 8K-And the content, and why wired connections sometimes seem to be slower than wireless connections.
What is it? LAN-The connector and why you need it in the TV Xiaomi
LAN-A local area network connector is a physical port for connecting a TV to the Internet or a LAN via an Ethernet cable, and unlike Wi-Fi, where the signal is transmitted through the air, the data is transmitted over a wire, which has several key advantages:
- 🔌 Connection stability: no interference from other devices (microwaves, neighbouring routers) or thick walls.
- 🚀 Maximum speed: up to 1 Gbps (in theory) against 300-600 Mbps for most Wi-Fi routers.
- 🎮 Minimum ping: critical for online gaming (e.g., via Google Stadia or Google Stadia) NVIDIA GeForce NOW).
- 📺 No loss of quality: in streaming 4K HDR or 8K cable excludes the "hanging" of the picture.
In Xiaomi TVs (e.g. Mi) TV Q2 75" or "Redmi Smart" TV X55) LAN-The connector is usually located on the back panel next to HDMI-It's a port and a power connector. RJ-45 Compatible with any Cat Ethernet cable 5e But why didn't the manufacturer abandon it in favor of wireless technology:
- 📶 Network congestion: if many devices are connected to the router (smartphones, laptops, smart lamps), the speed on the TV can sag.
- 🏠 Distance to router: in large apartments or houses, the Wi-Fi signal weakens, and the cable guarantees stability.
- 🔒 Security: wired connections are harder to crack than Wi-Fi networks.
But LAN There are also downsides: the need to run a cable (sometimes across the room) and depend on the quality of the router. For example, if your router gives a maximum of 100 Mbps over the wire, then the TV will not get more - despite the support of 1 Gbps / with the port itself.
Which cable to choose for connection: Cat 5e, Cat 6 or Cat 7
Not every Ethernet cable is suitable for a Xiaomi TV if you want maximum speed and stability.
| Cable category | Max, speed. | Frequency | What tasks are suitable for | Price (for 5 m) |
|---|---|---|---|---|
| Cat 5e | 1 Gbps | 100 MHz | Stream Full HD, websurf | 150–300 ₽ |
| Cat 6 | 10 Gbps (up to 55 m) | 250 MHz | 4K HDR, Online games, large files | 300–600 ₽ |
| Cat 6a | 10 Gbps (up to 100 m) | 500 MHz | 8K, profession | 800–1500 ₽ |
| Cat 7 | 10 Gbps (up to 100 m) | 600 MHz | Future standards are redundant for TV | 1200–2500 ₽ |
For most of the Xiaomi users TV Cat 6 is optimal – it provides speed margin (even if your Internet is 100-200 Mbps) and is better protected from interference than Cat. 5e. Cat 7 and higher cables are redundant for TVs as their port LAN Physically limited to 1 Gbps.
When buying a cable, pay attention to:
- 🛡️ Screening: better to choose STP (foil screen) or FTP — This will protect against electromagnetic interference.
- 🔌 Connectors: must be properly compressed, without backlash. Bad clamp is a common cause of "breakdowns" of the connection.
- 📏 Length: don't take "with a margin" - the longer the cable, the higher the signal attenuation. Optimum up to 10-15 meters.
⚠️ Warning: Don't use cheap "no-name" cables from Chinese stores.They often don't fit the stated category and can limit speeds to 100 Mbps, even if labeled as Cat 6.
Step-by-step: how to connect Xiaomi TV to the Internet LAN
Connection through LAN-The connector only takes a few minutes, but there are nuances that will help to avoid problems:
- 🔌 Connect the cable at one end to the LAN-The port of the TV, the other to the free port on the router. Make sure the connectors are latched (the characteristic click should be heard).
- ⚙️ Turn on the TV and go to Settings → The Internet and the Internet → Wired network.
- 🔄 Select the type of connection: DHCP (automatic IP) — recommended for most users. IP — Only if your provider requires manual settings.
📶 Wait for the connection. The screen will show a message "Network is connected" and the current speed (for example, 100 Mbit / s or 1 Gbit / s).
If the TV is not connected:
☑️ What to do if LAN doesn't work
On some models (e.g., Mi) TV 4S) Additional adjustments may be required MAC-If your ISP links the Internet to a particular device, copy it. MAC your PC (where the internet works) and type it in your TV settings along the way:
Settings → Network and Internet → Wired network → Additional → Clone MAC- address⚠️ Note: If the speed is lower than expected after the connection (for example, 100 Mbps instead of 1 Gbps), check: Cable - must be Cat 5e Port on router - some budget models are limited to 100 Mbps. TV settings - in Settings → Network → Select the 1000 Mbps mode (Full Duplex).
LAN Wi-Fi: What’s best for Xiaomi TV
Many users are wondering if you should mess with wires if you have Wi-Fi, and let's compare the two options in key terms:
| Parameter | LAN (wire) | Wi-Fi (wireless network) |
|---|---|---|
| 📈 Speed. | Up to 1 Gbps (in practice 900–950 Mbps) | Up to 600 Mbps (on Wi-Fi 5) or 1-2 Gbps (on Wi-Fi 6) |
| 🕒 Stability | Nearly 100% (no interference) | Depends on distance, walls, other devices |
| 🎮 Ping (delay) | 1-5 ms | 10–50 ms (can gallop) |
| 📺 streaming 4K/8K | No loss of quality | Possible "suspend" with a weak signal |
| 🔌 Convenience | We need to lay the cable. | Out of the box, no wires. |
Conclusion: LAN definitely better:
- 🎬 streaming 4K HDR or 8K (no buffering).
- 🎮 Online Games (fewer lags).
- 💾 Download large files (such as software updates).
Wi-Fi is suitable if:
- 🏡 The router is next to the TV (signal) ≥70%).
- 📱 Your Internet is slower than 100 Mbps (there will be no difference).
- 🔌 Cable laying is not possible (for example, a TV hangs on the wall).
💡
If you have a router with Wi-Fi 6 (e.g. Xiaomi) AX3600), The TV supports this standard (like the Mi). TV Q2), difference LAN It's going to be minimal. 8K-content is better to use the wire anyway.
Common problems with LAN Xiaomi TV and their decisions
Even after connecting correctly, users sometimes encounter errors, and let’s look at the typical problems and ways to fix them:
1.The TV doesn't see the wired connection
Reasons:
- 🔌 Poor contact in the connector (check if the connector is bent).
- 🔄 Faulty cable or port on the router.
- ⚙️ Unplugged. DHCP on the router (you need to enable in the settings of the router).
Solution: Try another cable or port on the router. If it doesn't work, reset the network settings on the TV:
Settings → System → Reset → Reset Network settings2.Cable speed is lower than Wi-Fi.
Reasons:
- 📉 Cat cable 5 Cat 5e/6.
- 🔌 Port on the router is limited to 100 Mbps.
- ⚙️ In the settings of the TV, the mode is 100 Mbit / s instead of 1 Gbit / s.
Solution: Check the characteristics of the router (for example, TP-Link) TL-WR840N If the router is old, consider replacing it with a model with gigabit ports (for example, Xiaomi Mi Router). 4A Gigabit).
3.The Internet through LAN It works, but there is no access to some sites.
Reasons:
- 🔒 Blocking at the provider level (for example, Roskomnadzor).
- 📡 Wrong. DNS-server.
- 🛡️ Parental Controls on the router are included.
Solution: Change. DNS In the settings of the TV set at 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare):
Settings → Network and Internet → Wired Network → Additional → DNS⚠️ Attention: If after the shift DNS The Internet is gone completely, return the default settings and reboot the router. Your ISP may be blocking third-party devices. DNS.
4.The TV itself is disconnected from LAN
Reasons:
- 🔋 Energy savings (in some Xiaomi models, the port is turned off when it is simple).
- 🔌 Poor contact or damaged cable.
- ⚡ Power surges on the grid.
Solution: Turn off the energy saving mode:
Settings → Power supply → Power saving mode → DisconnectCan I use it? LAN Wi-Fi at the same time on Xiaomi TV
Xiaomi TVs do not support simultaneous use LAN Wi-Fi and Wi-Fi to increase speed (unlike some smartphones or PCs), but there are two scenarios where both connections can work in parallel":
- 🔄 Backup connection: If the main connection (LAN) If the TV is interrupted, it will automatically switch to Wi-Fi (if it is configured), which is useful if the cable sometimes leaves.
- 📡 Some applications (such as Mi Home for smart home management) can use Wi-Fi even if the main traffic is through a cable.
To set up a backup connection:
- Connect your TV to Wi-Fi (even if the cable is already plugged in).
- Go to Settings. → The Internet and the Internet → Wired network → Priority of connection.
- Select a Wired Network as a priority.
Important: when active LAN-Wi-Fi connection will be disabled for most tasks (for example, streaming Netflix or YouTube.
💡
If you want maximum stability, use only LAN. Wi-Fi as a backup only if the cable is often leaving or the router is unstable.
How to optimize network settings for streaming 4K/8K
If you're watching high-resolution movies or playing cloud games, standard network settings may not provide enough speed.
1. Enable Game or Media mode on the router
Many modern routers (for example, Xiaomi) AX6000 or ASUS RT-AX88U) Have special modes to prioritize traffic:
- 🎮 Game Mode – Reduces ping for online gaming.
- 📺 Media Mode – Prioritizes streaming (e.g. Netflix or Disney)+).
Activated in the router’s web interface (usually at 192.168.1.1 or 192.168.0.1).
2. Set up QoS (Quality of Service)
QoS allows you to distribute bandwidth between devices, for example, you can give a Xiaomi TV the highest priority:
Router settings → QoS → Add rule → Specify MAC- TV address → Priority: High3. Disable background updates
Xiaomi TVs can automatically update software or apps in the background, which eats up speed.
Settings → Applications → Auto Update → Disable4.Use static IP-address
Dynamic IP (down DHCP) It can change, sometimes causing the connection to break. IP:
Settings → Network and Internet → Wired Network → Additional → Set up IP manuallySpecify an address from your local network range (e.g. 192.168.1.100 if the router distributes addresses from 192.168.1.2 to 192.168.1.254).
⚠️ Note: If after the appointment of static IP The Internet is gone, check if it conflicts with another device on the network. Use the ping command in Windows Command Prompt to make sure the address is free: ping 192.168.1.100 If you get an answer, you're going to get a ping command. IP busy - choose another.
