In this article, we'll look into these issues. all stages of setup — from preparing the router to solving typical errors, taking into account firmware features Hyundai 2020–2026.

It is important to understand that the connection algorithm may differ slightly depending on TV models (For example, Hyundai H-LED43S5900 vs Hyundai QLED55Q70) and firmware version. We'll focus on the general steps, but if your TV is behaving unusually, check Settings → Support → TV Info and check the official documentation. Also keep in mind that some budget models Hyundai (for example, series H-LED32T3700) may not support 5 GHz - more on this in the section on choosing a network.

Before you begin, make sure that:

• 📶 The router is turned on and distributing Wi-Fi (the network indicator is green/blue).
• 🔐 You know the exact password for your network (if you forgot it, look on the sticker on your router or in your provider's personal account).
• 📺 The TV is in a strong signal reception area (no further than 10 meters from the router, with no obstacles).
• 🔄 The "Hidden Network" mode is disabled on the router (if it is enabled, you will have to enter the SSID manually).

1. Preparing the router: optimal settings for Smart TV

Connection problems Hyundai Smart TV In 80% of cases, Wi-Fi issues are related to incorrect router settings. Before accessing your TV's menu, check the following settings:

Network frequency (2.4 GHz vs 5 GHz): most televisions Hyundai (especially those released before 2022) are only supported 2.4 GHzIf your router distributes two networks (for example, MyWiFi_2G And MyWiFi_5G), choose the first one. Exception: 2023-2026 QLED series models (e.g. Hyundai QLED65Q800B) also work with 5 GHz, but can “lose” the connection when the signal is weak.

Channel width: in the router settings (section Wi-Fi → Wireless Network Settings) set the channel width 20 MHz for 2.4 GHz. Wide channels (40 MHz) may cause interference, especially in multi-apartment buildings.

Security mode: televisions Hyundai compatible with WPA2-PSK (AES)If you have WPA3 or mixed mode WPA/WPA2, try switching temporarily to WPA2 - this often solves the problem with the "endless password request".

⚠️ Attention: If your router issues IP addresses in the range 10.0.0.x or 172.16.x.x, not the standard one 192.168.x.x, the TV may not connect. In this case, manually configure the DHCP pool in the router settings, for example, 192.168.1.100–192.168.1.200.
