Why Xiaomi TV is not connected to the Internet: a full analysis of the causes and solutions

Introduction: Why the Connection Issues Are So Common

Xiaomi TVs are some of the most popular Smart TV It's a combination of price, functionality and integration with the Mi Home ecosystem, but even flagship models like the Mi are also available. TV Q2 75" or Mi" TV P1 Internet connection problems occur periodically, and service centers say that about 30 percent of all calls are due to network failures, from the banal “does not see Wi-Fi” to authentication errors or endless reception. IP-address.

The reasons can be in the settings of the TV itself, and in external factors, from outdated firmware to conflict with the router. TV Stick and full Mi TV 4S will be different – for example, consoles are more likely to suffer from overheating of the Wi-Fi chip, and TVs – from failures in the module BCM4356 (In this article, we will discuss all possible scenarios, including rare cases such as lockdowns. MAC-Provider address or failure in Xiaomi Cloud service.

Before you go to the instructions, answer one question – this will help narrow the range of possible problems:

1. Checking the basic parameters of the network

Start with the basics: make sure that the problem isn't with the router or the ISP, and often people blame the TV when the Internet is actually off in the whole house.

• 📶 Reboot the router. Turn it off for 30 seconds, then turn it on again. Wait for full load (indicators should burn steadily).
• 📱 Check the Internet on other devices. If no gadget (smartphone, laptop) is connected, the provider has a problem.
• 🔌 Test different types of connections. If Wi-Fi doesn't work, try connecting the TV to the router via an Ethernet cable (even temporarily).
• 🔄 Change the Wi-Fi range. In router settings, switch from 5 GHz to 2.4 GHz (or vice versa).Some Xiaomi models don't work well with 5 GHz due to a weak module.

If other devices are connected normally and the TV is not, move on to the next section. If the problem is global, check:

• 💰 balance of the personal account with the provider (sometimes disconnected for non-payment without notice).
• 📡 For example, Rostelecom or Beeline may have an accident — see the coverage map on the website.
• 🛠️ Router settings. It might be on. MAC-filter DHCP.

💡

If you have Mi. TV 4A or 4C (2018-2019), try connecting to a network with a name without Cyrillic and special characters. SSID.

2. Wi-Fi settings on Xiaomi TV

If the basic checks didn't work, let's look at the settings on the TV itself, and let's start with the obvious thing: getting your password right, and it's a trivial thing, but according to Xiaomi Service, 15% of all Internet searches are solved this way.

How to check and change your Wi-Fi settings:

1. Open Settings → Network and Internet → Wi-Fi.
2. Select your network. If it's not on the list, click Update (button in the upper right corner).
3. Enter your password. Make sure the letter register matches (password and password are different!).
4. If the connection does not occur, click on Additional settings and select Forget Network, then reconnect.

If the TV sees the network but doesn’t connect, try:

• 🔑 Change the encryption type on the router — WPA2-PSK (AES). WPA3 It may not be supported by older Xiaomi models.
• 📶 Reduce the channel width in the router settings. Instead of auto or 40 MHz, install 20 MHz, which will increase stability.
• 🔄 Disable the Quick Connection feature (if any) in the TV's Wi-Fi settings. It sometimes conflicts with TP-Link routers and ASUS.

If after these manipulations the TV still does not connect, move to the next section – perhaps the problem is in the firmware or hardware.

3. Update firmware and reset settings

Outdated firmware is one of the most common causes of network failures. TV 4S beforehand MIUI TV 3.0.15 was a bug with a connection to networks with WPA3, A in the Mi Box S to Android TV 9.0 - problems with IPv6.

How to update firmware:

1. Go to Settings → About TV → System Update.
2. Click Check Updates. If a new version is available, install it.
3. If the update is not available, try connecting to the internet via Ethernet or a mobile hotspot.

If the update doesn’t help or the TV doesn’t connect to the network at all, reset your settings:

1. Open Settings → Device → Reset and Recovery.
2. Select Reset all settings (not to be confused with Reset to factory – it will delete all data!).
3. After the reboot, try connecting to Wi-Fi again.

Attention: on Mi models TV 4A and 4C If you have firmware older than 2020, resetting your settings may result in the loss of licenses for preinstalled services (such as Netflix or Prime Video), in which case you will need to re-activate via Xiaomi Account.

4.Problems with DHCP manually IP

If the TV is infinitely IP-address or make an error such as "failed to receive" IP", The problem may be in the server. DHCP This is especially true for networks with a large number of connected devices (more than 10-15 devices).

What to do:

1. Go to Settings → Network and Internet → Wi-Fi.
2. Select your network, then click on Additional Settings.
3. Scroll down and select Settings. IP.
4. Switch from DHCP static IP And you enter it manually:

After you save the settings, restart the TV. DHCP, The connection should be earned.

💡

If, after manual adjustment, IP The TV is not connected anyway, check if the one you choose conflicts. IP To do this, type 192.168.0.100 (or the one you specified) in your computer browser. If the router login page or other device opens, change the last octet (for example, to 192.168.0.101).

Hardware malfunctions and diagnostics

If none of the previous methods worked, the problem could be hardware, and most often, it fails.

• 📡 Wi-Fi modules (especially Mi models) TV 4 and Mi Box S after 2-3 years of service).
• 🔌 Ethernet port (contact oxidation or physical damage).
• 🔋 Power supply (insufficient voltage on the communication module).

How to diagnose a hardware malfunction:

1. Check the indicators: If the network indicator on the TV doesn't blink at all when connecting to Wi-Fi, it's likely that the module has burned out. If the indicator flashes red, there's a power problem or a motherboard problem.
2. Check the physical connection: For Ethernet, check the port for bent contacts. Try another cable. For Wi-Fi, hold the router as close to the TV as possible (1-2 meters away). If the signal appears, there is a problem in the TV antenna.

Test another power source

Mi TV Stick

Mi Box

If you suspect a hardware malfunction but are not sure, use the diagnostic mode:

1. Turn off the TV.
2. Press the Menu button on the remote and, holding it, connect the power.
3. Wait for the service menu to appear (usually in 10-15 seconds).
4. Select Network Test and follow the logs, and if you see errors like "Wi-Fi chip not found" or "Ethernet port failure," it confirms a hardware problem.

💡

On the Mi models TV The 5 Pro and the newer diagnostic menu can be blocked, and you’ll need a service remote (sold on AliExpress) or special software like Xiaomi to open it. ADB Tools.

6. Conflicts with the router and the provider

Sometimes the problem isn't with the TV, but with the router or the ISP's limitations.

• 🚫 Lockdown MAC-Some providers (e.g. MTS or Beeline) link the Internet to MAC-If you connect the TV directly (without the router), the Internet may not work. MAC-Router address on TV or call in support of the provider.
• 🔒 Device limit: Some tariffs have a limit (e.g. no more than 5 devices at a time.
• 🌍 Geo-blocking. If you're using VPN On a router or TV, some services (such as YouTube or Netflix) may block the connection. VPN And check the Internet.
• ⚡ Speed limit: The provider can artificially limit the speed for certain devices (e.g., Smart devices). TV). Check this with a speed test on your TV and compare it to other devices.

How to check the lockdown MAC-address:

1. Find out. MAC-TV address: Settings → On TV. → Status → MAC-address Wi-Fi/Ethernet.
2. Call the provider and check if the Internet is connected to the MAC-router.
3. If yes, ask for an addition. MAC-Address to the list of allowed TVs or clone MAC router to the TV (if such a function is in the network settings).

If the problem is in the router, try:

• 🔄 Change the Wi-Fi channel in router settings. Automatic selection can lead to conflicts with neighboring networks.
• 🛡️ Disable DDoS protection (if any) sometimes it blocks legitimate devices.
• 📡 Update the router's firmware, and outdated software may conflict with today's TVs.

7. Specific problems of Xiaomi models

Different Xiaomi TV lines have their own "diseases":

If your model is not listed in the table, check the error log:

1. Connect the TV to the router via Ethernet.
2. Go to Settings. → Support → Journal of the system.
3. Find the tagged records. [WiFi] or [Network]. Usually, there is an error code, for example, ERROR_0x1234).
