However, many users encounter difficulties when setting up Wi-Fi for the first time: the network can't be found, the password doesn't work, or the connection keeps dropping.

In this article, we'll cover all possible connection methods—from the basic one via the set-top box menu to alternative methods using WPS or an Ethernet adapter. We'll pay special attention to common mistakes, which interfere with stable operation: weak signal, incompatible encryption standards, IP address conflicts. You will also find up-to-date information on supported frequencies (2.4 GHz vs. 5 GHz) and router requirements for different firmware versions. Big TV.

If you've already tried connecting and nothing worked, don't rush to call support. In 90% of cases, the problem can be solved by configuring the router or resetting the set-top box. And for those who just unpacked the device, we've prepared a solution. A step-by-step checklist with interface photos (valid for firmware versions from 2023–2026)to avoid typical mistakes made by beginners.

1. Preparing to connect: What to check before setting up Wi-Fi

Before you configure your set-top box, make sure your home network is ready for the new device. Connection issues are often not caused by the set-top box itself, but by incorrect router settings or a congested channel.

Here's what you need to do in advance:

• 📶 Check your Wi-Fi coverage areaThe set-top box should be no more than 10 meters from the router (without any concrete or metal obstructions). Use a smartphone to test: if the signal is weak (1–2 bars), the set-top box will also be unstable.
• 🔒 Make sure the network is not hidden (SSID broadcast is enabled)Some routers hide the network name by default, so the set-top box simply won't see it.
• 🔄 Reboot your routerUnplug it for 30 seconds, then plug it back in. This will clear the temporary DHCP errors.
• 📱 Check the number of connected devicesIf more than 10 devices are already connected to the router, the set-top box may not receive an IP address.

Pay special attention encryption standard. Prefixes Big TV (all models, including SML-5285TBK And SML-5284T2C) support only WPA2-PSK (AES)If your router uses WPA3 or mixed mode WPA/WPA2, the connection will be unstable or impossible. To change the settings:

1. Go to the router's web interface (usually at 192.168.0.1 or 192.168.1.1).
2. Find the section Wireless Network → Security Settings.
3. Select WPA2-Personal and encryption type AES.
4. Save the changes and reboot the router.

⚠️ Attention: If you have a dual-band router (2.4 GHz + 5 GHz), it is better to connect the set-top box to the network 2.4 GHzThe 5 GHz band may not be supported or may work unstable on older models of set-top boxes (manufactured before 2022).

2. Step-by-step instructions: connecting via the set-top box menu

The most reliable connection method is through the set-top box's built-in menu. The interface may differ slightly depending on the firmware version, but the general logic remains the same.
