Unlike premium brands like Samsung or LG, interface Dexp may seem less intuitive, especially if you are setting it up for the first time Wi-Fi on TV.

In this article, we'll cover all possible connection methods—from the standard method via the settings menu to alternative solutions for older models or weak signals. You'll learn how to avoid common mistakes (for example, Authentication error or IP address not received), which router parameters affect connection stability, and what to do if the TV "doesn't see" the network. We'll cover this separately. Wi-Fi optimization for streaming - so that the films in 4K didn't "slow down" and online games didn't lag.

Before you move on to your TV settings, make sure the problem isn't with your router or the network itself. Here's mandatory checklist:

• 🔌 The router is turned on and indicator Wi-Fi (usually green or blue) is on without blinking. If it blinks, reboot the device.
• 📶 The signal is strong enoughThe TV should be no more than 10 meters from the router (without obstructions such as concrete walls). Use your smartphone to check: if it shows 1-2 bars of signal, the signal is too weak.
• 🔒 The Wi-Fi password is known and entered correctly (case-sensitive!). If you forgot, look it up on the router sticker or in your provider's account.
