Why Wi-Fi is not connected on Xiaomi TV: full diagnostics and fix

You've turned on the new Xiaomi TV Or did you update your firmware but your TV refuses to connect to Wi-Fi? Or is it a grid that's always breaking? This is a problem that many owners of smart TVs of the brand, from budget Mi TVs, are familiar with. TV 4A before the flagship Xiaomi OLED Vision: 80% of the time, it’s not hardware faults that are to blame, but configuration errors, protocol conflicts, or firmware bugs.

In this article, we will discuss all the possible reasons why Xiaomi is a great company. TV It doesn't connect to Wi-Fi, from the banal (incorrect password) to the exotic (5GHz channel conflict), you'll get step-by-step instructions with illustrations from real TV menus, router compatibility tables, and proven diagnostic methods. Particular attention will be paid to the hidden settings of the developer, which the manufacturer does not advertise, but which often solve the problem.

If you've tried rebooting your router and TV before, don't waste your time. Start with the diagnostics section, where we can determine the exact cause of your problem in 3 minutes. TV 9+ A separate block about the new restrictions of Google on connecting to open networks was added.

1. Quick Diagnostic: Determine Your Problem in 3 Steps

Before you go through the settings, answer three questions. This will narrow down the possible causes of the problem. 12 before 2-3:

1. Does your TV not see your network at all (it is not on the list of available Wi-Fi)?
2. The network is visible, but when connected, it gives an error (for example, “Authentication failed” or “Receiving” IP-address")?
3. The connection passes, but the Internet does not work (Wi-Fi icon is active, but the Internet is not working). YouTube/browser not loaded)?

Each of these scenarios has unique solutions, such as if the TV doesn't see the network at all, the problem is more likely to be the router settings (hidden). SSID, Incompatible Wi-Fi standard, and if an authentication error occurs, it's the security protocol or password that's the fault.

For convenience, we have collected the symptoms and probable causes in a table:

If your case didn’t make it to the table, check out the Rare Causes section, where we deal with firmware issues, hardware malfunctions, and conflicts with other devices on the network.

2.The TV doesn't see the Wi-Fi network: 4 proven ways to fix

If your network does not appear in the list of available connections on Xiaomi TV, The problem lies in one of the four parameters:

• 🔍 Hidden SSID — router does not broadcast the network name (frequent security settings).
• 📡 Incompatible Wi-Fi standard – TVs do not support modern protocols (e.g. Wi-Fi 6 on older models).
• 🔌 Unplugged. DHCP — router doesn't give away IP-address.
• 🛡️ Filtration by MAC-address – in the settings of the router is blocked MAC television.

Let’s start with the simplest – checking the hidden SSID.

2.1 How to connect to a hidden Wi-Fi network on Xiaomi TV

If your router is configured to covertly broadcast the network name (SSID), The TV won't show it on the list:

1. Open Settings → Network and Internet → Wi-Fi.
2. Select "Add Network" (or "Connect to Hidden Network").
3. Enter the exact network name (SSID) register-based and password-based.
4. In the Security field, select the encryption type (usually WPA2-PSK).

Get the exact name. SSID (Ask the provider or look at the router sticker)

Check the letter register in the network name

Choose the Right Security Protocol (WPA2-PSK router)

Reboot the router after adding the network-->

If after entering the data connection does not occur - check whether the router is not enabled filtering by MAC-We'll talk about this in section 2.4.

2.2 Wi-Fi standards compatibility issues: what to do

Xiaomi TVs of different generations support different Wi-Fi standards:

• Mi TV 4A/4S (2018-2019): only 802.11n (Wi-Fi 4), maximum speed 150 Mbit/s.
• Mi TV 4X/4C (2020-2021): 802.11ac (Wi-Fi 5), before 867 Mbit/s.
• Xiaomi OLED Vision / Q2 (2022+): 802.11ax (Wi-Fi 6, up to 1200 Mbps.

If your router is running in mode 802.11ax (Wi-Fi 6) and TV older than 2022 - the network may not show.Solution:

1. Go to the router settings (usually 192.168.0.1 or 192.168.1.1).
2. Find the Wireless section → Wireless Mode (or "Wireless Network Mode").
3. Set up a mixed mode: 802.11n/ac or 802.11b/g/n.
4. Save the settings and restart the router.

💡

If the Internet speed has dropped after the change of mode, return the settings back and try to connect the TV via cable (Ethernet) or through the Powerline adapter.

2.3. DHCP Disconnected: How to Assign Static IP manually

If the router settings are disabled DHCP-The server won't get the TV IP-The address will automatically not see the network. IP:

1. From the TV's Wi-Fi menu, select "Add Network Manually".
2. Indicate. SSID password.
3. In the additional settings, select "Show additional parameters".
4. Install: IP-address: 192.168.0.X (where X is a number from 100 to 254 not occupied by other devices. Gateway: 192.168.0.1 (or 192.168.1.1). Subnet mask: 255.255.255.0. DNS: 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).

To find out the free ones IP-Addresses in your network, use the command in Command Prompt (Windows):

Filtration by MAC-How to Add a TV to a White List

Some routers block the connection of new devices MAC-To unlock Xiaomi. TV:

1. Find out. MAC-TV address: Go to Settings → On TV. → Status, find a line. MAC-address (Wi-Fi) - usually format 00:1A:2B:3C:4D:5E.

Wireless mode → Filter MAC-address

whitelist

⚠️ Note: Some routers (e.g. TP-Link) have filters MAC It works backwards, it blocks everything except the devices that are allowed by default, and if the TV isn't on the list, it won't connect.

3. "Authentication failed" error: 5 ways to get around

The message "Authentication failed" or "Incorrect password" appears when the TV cannot confirm the authenticity of the connection.

• 🔑 Incorrect password (yes, this is the most common reason).
• 🔒 Incompatible security protocol (e.g, WPA3 old-timer).
• 🌍 Regional restrictions (TV from China does not work with Russian routers).
• ⏳ Time synchronization failure (important for businesses with certificates).
• 📱 Conflict with another device (e.g., repetitive) IP).

Let's start with a password check -- it takes 10 seconds and solves 60 percent of cases.

3.1 How to Reset Your Wi-Fi Password If You Forgot

If you are not sure about the password:

1. Look it up on the router sticker (usually on the bottom panel).
2. If the password has changed, reset the router to factory settings: Press and hold the Reset button on the router. 10-15 Login/password will become standard (usually) admin/admin).

3.2 Safety protocol WPA3: Why the TV doesn't support it

Modern routers often use protocol. WPA3 For protection, but many Xiaomi TVs (especially until 2021) only support the same. WPA2. To correct:

1. Go to the router settings. → Wireless network → Security settings.
2. Change it. WPA3 on WPA2-PSK (ormixed WPA2/WPA3).
3. Save the settings and reconnect the TV.

⚠️ Note: If your router is running WPA3-Enterprise (With certificates, Xiaomi TV will not connect – this protocol is designed for corporate networks and is not supported by household appliances.

Regional restrictions: why Chinese TVs don't work in Russia

Xiaomi TVs released for the Chinese market (models with suffix) CN), They may block the connection to foreign routers because of:

• Restrictions on Wi-Fi (other frequencies are allowed in China)
• Lockdowns MAC-address.
• Lack of certification for Russian standards (for example, 802.11ac channel 165).

Decisions:

1. Change the router region to China (in wireless network settings).
2. Use the channels. 1-11 (They are universal for all countries).
3. Update your TV firmware to the global version (instructions in Section 6).

4. Wi-Fi connects but connection breaks: causes and fixes

If the TV is connected to the network, but through 1-2 The connection is broken, it's my fault:

• 🔄 Conflict IP-Addresses (two devices with the same address) IP).
• 📶 Weak signal (distance to router) >10m, obstacles).
• 🎛️ Channel overload (many devices on one channel).
• ⚡ Energy savings (TV turns off Wi-Fi in standby mode).

Let’s start with the simplest thing: checking the strength of the signal.

4.1 How to check the signal level of Wi-Fi on Xiaomi TV

To find out the strength of the signal:

1. Open Settings → Network and Internet → Wi-Fi.
2. Choose your network (don’t connect!).
3. Pay attention to the signal level indicator (usually displayed as stripes or percentages).

Optimal values:

• ✅ Great: 70-100% (3-4 stripes).
• ⚠️ Acceptable: 50-70% (2 stripes).
• ❌ Bad: <50% (1 stripe or “Weak signal").

If the signal is weak:

• 📍 Move the router closer to the TV (ideally within a 5-meter radius without walls).
• 🛠️ Use a Wi-Fi repeater (e.g. Xiaomi Mi Wi-Fi Repeater 2).
• 📡 Change the channel on the router (instruction below).

4.2 How to change Wi-Fi channel on router for stable connection

If you have a lot of Wi-Fi networks in your home, they can interfere with each other to find a free channel.

1. Install the Wi-Fi Analyzer (Android) or NetSpot (iOS) app on your smartphone.
2. Look at the channels that are occupied by the neighbors.
3. In router settings (192.168.0.1), find a wireless network → Canal.
4. Select the least loaded channel (e.g. 1, 6 or 11 for 2.4 GHz).

For 5 GHz, we recommend 36, 40, 44, 48 channels – they are least susceptible to interference.

💡

If you have a dual-band router, try connecting your TV to a 5GHz network – there’s less interference, but the signal is worse through walls.

Conflict IP-Addresses: How to Assign Static IP

If two devices on the network have the same IP, The router will break the connection to check:

1. Open the Command Prompt on your PC and type: ping 192.168.0.100 (replace 100 with 100) IP your TV set).
2. If you get a response from another device, it’s a conflict.
3. Solution: Assign a static TV set IP (instruction in section 2.3).

4.4. Turn off Wi-Fi energy savings

Some Xiaomi TVs turn off the Wi-Fi module in standby mode to save power.

1. Go to Settings. → Energy conservation.
2. Find the item "Stop Wi-Fi in Sleep mode" and deactivate it.
3. If there is no such item, update the firmware (instructions in section 6).

5. Wi-Fi is connected, but the Internet is not working: 4 reasons

If the TV is connected to the network, but the pages are not loaded, and the applications give an error, the problem lies in one of four components:

• 🌐 DNS-servers (incorrect or blocked).
• 🚫 Lockdown MAC-provider.
• 🔧 Restrictions of Parental Controls on the Router.
• 📡 Gateway failure (router does not transmit traffic further).

Let's start with the simplest thing: shifts. DNS.

5.1 How to change. DNS Xiaomi TV speed up the Internet

If DNS-The servers of the provider are slow or blocked, replace them with public ones:

1. Open Settings → Network and Internet → Wi-Fi.

3. In the DNS field 1 enter 8.8.8.8 (Google), in DNS 2 - 1.1.1.1 (Cloudflare).
4. Save and reconnect.

Recommended DNS for Russia:

• 8.8.8.8 Google (fast, but may be blocked by some providers)
• 1.1.1.1 Cloudflare (private, no logs).
• 77.88.8.8 - Yandex (optimized for Runet).

Checking the lock MAC-provider

Some providers (for example, Beeline or MTS) link the Internet to the Internet. MAC-If you connect the TV directly or change the router, access may be blocked:

1. Call the provider and ask for a new one. MAC-address.
2. Clone. MAC-Address of the old router to the new one (option) MAC Clone in settings).
3. Use the router in bridge mode.

Parental controls and access restrictions

If the router has parental controls on, it can block the TV from accessing the Internet to check:

1. Go to the router settings. → Parental Control or Access Control.
