This article provides a comprehensive guide that takes into account the specifics of popular brands (Samsung, LG, Sony, Xiaomi) and solutions for non-standard situations.

1. Preparing the router: what settings to check before connecting

Before setting up your TV, make sure your router is ready for a wireless connection. Router configuration errors are the cause of 70% of connection problems. Smart TVPay special attention to the following parameters:

✅ Wi-Fi standard: TVs older than 2018 may not support Wi-Fi 6 (802.11ax)In your router settings, select mixed mode. 802.11a/b/g/n/ac or 802.11n/ac for compatibility. On new models (Samsung QLED 2023+, LG OLED C3) you can leave it Wi-Fi 6, but provided that the router supports WPA3.

✅ Channel and bandwidth: Automatic channel selection often causes interference. Manually set the channel in the range 1–11 (for 2.4 GHz) or 36–48 (for 5 GHz) and bandwidth 20 MHz (for stability). Width 40/80 MHz will give higher speed, but may cause connection breaks on a weak signal.

• 📡 Network name (SSID): Make sure it does not contain Cyrillic, spaces or special characters (for example, #, $). Optimal format: MyWiFi_5G or HomeNetwork.
• 🔒 Security type: Use WPA2-PSK (AES) or WPA3-PSK. Outdated WEP not supported by modern TVs.
• 🔄 DHCP: Must be enabled (automatic IP address distribution). If the TV is not receiving an IP address, check the address range in the router settings (e.g. 192.168.1.100–192.168.1.200).

⚠️

Attention: If you have a dual-band router, disable the feature. Smart Connect (automatic switching between 2.4 GHz and 5 GHz). Some TVs (Sony Bravia 2019–2021) do not work correctly with this option and lose connection.
