What to do if your Xiaomi TV doesn’t see Wi-Fi

When Xiaomi’s smart TV stops seeing or refuses to connect to a wireless network, it is one of the most common problems in the operation of Android TV. The user can face this suddenly: yesterday the device worked properly, today the list of available networks is empty, or the connection is constantly interrupted. This can occur both after a planned firmware update, as a result of a router failure or a change in security settings.

Most of the time, the problem isn't with hardware failures in the Wi-Fi module, but with software conflict or incorrect router parameters. The Android TV system on which Mi TVs and Redmi TVs are based is sensitive to frequency bands and encryption protocols. Before you bring a device to a service center, you should conduct a comprehensive diagnostics that helps restore the wireless interface to work on your own in 90% of cases.

It is important to understand that the lack of response of the TV to the network can be caused by overheating of the communication module or static electricity. Often it is enough to complete a full cycle of rebooting the equipment to reset the accumulated errors, below we will discuss in detail all possible causes and provide a step-by-step algorithm for correcting the malfunction.

Primary diagnostics and router inspection

The first step should always be to check the source of the signal. If a Xiaomi TV does not see Wi-Fi, it does not always mean that the TV itself is malfunctioning. It may be that the router has stopped broadcasting SSID (network name) or is operating in a mode that is incompatible with the TV receiver. You need to make sure that other devices in the house, such as smartphones or tablets, are stable connections to the Internet through the same access point.

Notice the frequency range. Many of the older Mi TVs. TV only support the range 2.4 GHz and cannot physically see networks 5 GHz.If your router is set to work only in the range 5 GHz or using Smart Connect technology, which combines both bands under a single name, the TV may behave incorrectly. In router settings, you should try to separate networks by giving them different names, for example,"Home_2.4" and"Home_5".

⚠️ Note: If you have changed your router settings (channel, channel width, or encryption type), be sure to reboot your router completely by removing it from the outlet. 10-15 Seconds before trying to reconnect the TV.

It is also worth checking whether the router is not enabled filtering by MAC-If you activate this feature, the TV won't be able to access the network, even if you have the right password. MAC-TV address in the "About System" or "Network" section and add it to the white list of allowed devices in the router's admin panel.

Basic reset and power reset

The simplest, but often ignored, method is a full power reset (Cold Boot). Unlike a conventional remote shutdown, when the TV goes into standby mode, a full power reset clears RAM and restarts all system processes, including the drivers of the network module, you need to turn off the TV, disconnect the power cord from the socket and wait at least 2-3 minutes.

While the TV is off, it is also recommended to turn off the router. Turn on the router first and wait for the operating system to fully load it (usually 1-2 minutes), only after that turn on the TV. This sequence of actions ensures that the network TV module will search for a fully ready-to-work network, which eliminates timeouts when connecting.

If the problem is software-based and caused by Network Manager freezing on Android, this procedure often resolves the problem instantly, and in some cases, it may be necessary to repeat the shutdown cycle 2-3 times in a row to reset the static charge from the board.

Setting up Wi-Fi settings on the TV

If the basic reboot didn't work, you should go into the settings of the Xiaomi TV itself. Sometimes the system saves the wrong configurations of the previous connection. Go to the Settings → Network and Internet menu. Find your network in the list, select it and click "Forget Network" or "Delete." After that, try to find the network again and enter the password.

An important parameter is the installation of static IP-Addresses, in mode DHCP (Automatic settings may not be able to get the correct address from the router due to conflicting addresses. IP-To do this, in the Wi-Fi settings, select your network, go to the advanced settings and change the type. IP s"DHCP" on "Static".

Use it as an address. IP For example, if the router addresses 192.168.1.1, ask the TV 192.168.1.150. DNS Use the same router address or use public DNS This is often used by Google (8.8.8.8) to help bypass protocol errors. DHCP.

⚠️ Attention: When manually adjusted IP-Make sure that the number you select (the last digit) is not occupied by another device on your local network, otherwise there will be a conflict. IP-address.

Change of region and time zone

One of the specific features of Xiaomi TVs is that content and some system functions are region-specific. If you select a region in your system settings where certain Wi-Fi frequency channels are prohibited or work differently, the TV may not see your network, for example, in some regions channels 12 and 13 may be limited.

Try changing the region in your TV settings. Go to Settings → General → Region (the path may vary depending on the PatchWall version or pure Android). Changing the region from China to Russia or India can reconfigure the device's network stack. Once the region is changed, the TV will automatically restart.

Also check the correct setting of time and date. Inconsistency of system time with real time can lead to login errors on the network, especially if you use secure protocols with certificate verification, set automatic time synchronization over the network or set correct values manually.

Updating and flashing the system

Software bugs in the Android TV operating system or PatchWall shell often cause unstable Wi-Fi module. Manufacturers regularly release updates containing security fixes and driver patches. Check for updates in Settings → About TV → System Update.

If automatic updates are not possible due to lack of network, you can try to update the system manually through the USB-Download the current firmware for your model from the official website, write the file to a flash drive (in the root of the disk, the file system). FAT32) And if you turn it on, you can actually suggest that you upgrade.

In extreme cases, if the problem occurred after the last update, a rollback to the previous version or a full reset to factory settings (Factory Reset) can help. This action will delete all your apps and accounts, returning the TV to the "out of the box" state. → On TV. → Reset.

💡

Before performing the reset to factory settings, be sure to take screenshots of important parameters or write down logins from applications, since it will be impossible to restore them automatically after resetting.

Hardware problems and the use of adapters

If none of the software methods worked, there is a high probability of hardware failure, which could be a Wi-Fi module failure, a leakage of the antenna plume inside the housing, or a problem with the motherboard, in which case the built-in Wi-Fi may no longer be determined by the system at all.

The easiest and most efficient solution for older or faulty models is to use an external USB Wi-Fi adapter. Xiaomi TVs support most standard adapters on Ralink, Mediatek or Realtek chips. You will need to purchase a compatible adapter (often sold as a "Wi-Fi receiver for Smart TV").

After connecting the adapter to USB-The port, the TV should define it as a priority network device. In some cases, you may need to install drivers if they are not built into the system, but modern versions of the device are not built into the system. MIUI TV Usually, the device is automatically picked up.

If the built-in Wi-Fi module burned, buying a new TV is not necessary - external USB-adapter-by-adapter 500-1000 RUB fully restores the functionality of Smart TV.
