Xiaomi TV doesn’t connect to Wi-Fi: A complete troubleshooting guide

Does your Xiaomi TV stubbornly refuse to connect to Wi-Fi, even though other devices in the house work without problems? TV, Especially after a firmware update or a router change, the reasons can lie in the settings of the TV itself, and in the parameters of the network, from the wrong wireless dot mode to the conflict. IP-address.

In this article, we will look at all possible scenarios: when the TV does not see the network at all, when it sees but does not connect, and when the connection is cut off after a few minutes. Particular attention will be paid to the models of 2020-2026 (Mi TV Q2 75, Mi TV 5X, Mi TV P1, etc.), where Wi-Fi problems are often associated with the features of the MIUI TV firmware. You will receive step-by-step instructions with illustrations of key steps, a table of routers compatibility and answers to frequent questions.

Before you start settings, make sure that the problem is not on the ISP side - check if the Internet is working on other devices (smartphone, laptop).

1. Basic checks: router, cables and power

Start with the obvious -- sometimes the problem isn't with the TV, it's with the surrounding infrastructure. Turn off the router for 30 seconds, then turn it back on. DHCP It can resolve conflicts. IP-If you have a dual-band router (2.4 GHz) + 5GHz), try to disable 5GHz in the settings - many Xiaomi models (especially Mi) TV 4A) more stable in the 2.4 GHz range.

Check the physical connections:

• 🔌 Make sure the router's power cable is tightly inserted into the socket and the device itself.
• 📡 If you use a repeater, try connecting directly to the router – sometimes the problem is with repeater settings.
• 🔄 Reboot the TV: press the power button on the remote for 5-10 seconds, then turn it on again.

Important! If your router supports Wi-Fi 6 (802.11ax) and your TV only supports Wi-Fi 5 (802.11ac) (relevant to Mi TV 4S and older), try turning off 802.11ax or enabling compatibility mode in your router settings, which can solve the problem of persistent connection breaks.

2. Wi-Fi setup on Xiaomi TV: step-by-step instruction

If the basic checks didn't work, we'll go to the settings of the TV itself. Go to the Settings menu → Network and Internet → Wi-Fi. Here you can expect three scenarios:

1. The TV doesn’t see any networks – a problem with the Wi-Fi module or antenna.
2. The TV sees the network but doesn’t connect to yours – an authentication error or router settings.
3. The TV is connected, but the internet is not working – a problem with DNS or routing.

For the first case, try manually adding the network:

1. From the Wi-Fi menu, select Add Network Manually.
2. Enter the network name (SSID) exactly to the point, including the register (large/small letters).
3. Select the security type: This is usually WPA2-PSK (if you’re not sure, look at the router settings).
4. Enter the password and save it.

If the TV sees the network but it gives an error "Unconnected" or "Authentication failed", try:

• 🔑 Make sure the password is entered correctly (try entering it on your smartphone to check it out).
• 🔄 Change the type of router security with WPA3 on WPA2-PSK (Many Xiaomi models do not support WPA3).
• 📶 Switch Wi-Fi channel in router settings to 1–11 (avoid automatic selection).

3. Reset network settings and update firmware

If the TV used to connect to Wi-Fi but now refuses to, resetting the network settings can help, which removes all the stored networks and returns the settings to the factory settings to make the reset:

1. Go to Settings → System → Reset and Recovery.
2. Select Network Reset (not to be confused with a full reset!).
3. Confirm the action and restart the TV.

Once reset, try reconnecting. If the problem persists, check the firmware's relevance. Outdated software often contains compatibility errors with modern routers.

1. Go to Settings → About TV → System Update.
2. If you have an update, download it and install it. Don't turn off the TV during the process!
3. After the update, reset the network settings again.

Critical information: 2023 Mi TV Q1E and Mi TV Q2 models were found to have a bug in MIUI TV 3.0.12 firmware that caused TVs to lose Wi-Fi connection after sleep, and the solution is to upgrade to version 3.0.15 or higher.

Manual modification DNS and IP-address

If the TV connects to Wi-Fi, but the Internet does not work (pages do not load, applications give an error), the problem may be in the Internet. DNS-servers IP. Try to manually prescribe. DNS from Google or Cloudflare:

1. Go to Settings → Network and Internet → Wi-Fi.
2. Click on your network name and select Change Network.
3. In the DNS section, select Manual and type 8.8.8.8 8.8.4.4 (or 1.1.1.1 for Cloudflare).
4. Save the settings and restart the TV.

If there is a conflict IP-addresses (type error "IP-Address already used, set static IP:

1. In the same network settings, select IP-address → Manually.
2. Specify IP from your subnet (for example, if the router has 192.168.1.1, select 192.168.1.100).
3. The gateway and subnet mask must match the router settings (usually 255.255.255.0).

5. Firmware problems and hardware malfunctions

If none of the previous methods worked, the problem may lie in the firmware or hardware. On Xiaomi models 2019-2020 (for example, Mi TV 4S 55) there was a bug in which after the update, Wi-Fi support disappeared, the solution is to roll back the firmware or reflash manually.

For manual flashing:

1. Download the official firmware for your model from the Xiaomi Support website.
2. Unpack the archive and copy the update.zip file to the flash drive (FAT32 format).
3. Insert the flash drive into the TV, go to Settings → About TV → System Update → Local Update.
4. Select a file and wait for the process to be completed.

If the problem is hardware (for example, the contact of the Wi-Fi module fell off), contact the service center.

• 📉 The TV doesn't see any network, even after the reset.
• 🔧 Settings menu → On TV. → Wi-Fi status is displayed as “Disable” or “Unavailable".
• 🔌 After physical exposure (such as moving the TV), the problem appears/disappears.

⚠️ Warning: If you decide to take apart a TV to check your Wi-Fi module, remember that this voids the warranty. The module is usually located on the main board and connected via a connector. M.2 Without soldering experience, it's not recommended to interfere!

6. Alternative ways of connecting to the Internet

If you can’t solve the problem with Wi-Fi, consider alternative connectivity options:

1. Connection via Ethernet cable

Most Xiaomi models (except the thinnest ones like the Mi TV Q1E 55) have a LAN port. Buy an Ethernet-to-USB adapter (if there is no port) and connect the cable directly from the router, which will give a more stable connection than Wi-Fi.

2.Use of USB-modem

Some Xiaomi TVs support USB-4G modem connectivity.

1. Buy a modem that supports NDIS (e.g. Huawei E3372).
2. Put it in. SIM-free-rate.
3. Connect the modem to USB-port of the TV and select in the settings of the network Mobile Internet.

3.Configuring the bridge through a smartphone

If you have a Xiaomi smartphone, you can distribute the Internet from your phone:

1. Activate modem modem mode on your smartphone (Settings → Network and Internet → Access Point).
2. Connect the TV to the access point created.
3. To save traffic, turn off automatic updates of apps on TV.

💡

If you are using Mi TV Stick or Mi Box, try connecting them through the USB-Hub with an external Wi-Fi adapter (for example, TP-Link) TL-WN725N). Some users solved the problem with connection breaks this way.

7. Compatibility of routers and TVs Xiaomi

Not all routers work equally well with Xiaomi TVs, for example, Mi TV 4A and Mi TV 4S often clash with ASUS RT-AX88U routers due to aggressive power saving settings.

If your router is not on the list, try:

• 🔧 Disable in router settings WMM (Wi-Fi Multimedia – sometimes it helps with connection breaks.
• 📡 Reduce the channel width from 40 MHz to 20 MHz (in wireless network settings).
• 🔒 Disable the protection. WPS — It can conflict with Xiaomi’s authentication algorithms.
