Connecting your TV to Wi-Fi: Step-by-step instructions for all models

Connecting your TV wirelessly to the internet gives you access to streaming services, online cinemas, and even cloud gaming. But what if Smart TV doesn't see the network or constantly loses connection? This article will help you understand the nuances of setting up Wi-Fi on TVs of different brands, from budget Xiaomi to bonuses Sony Bravia.

We won't limit ourselves to the basic instructions in the user manual. Here you'll find Unique solutions for cases where the TV does not connect to the 5G network or requires manual DNS configurationAnd if your router supports mesh systems, you'll learn how to optimize your connection for stable 4K streaming.

Before you begin, check two key points: whether the internet works on other devices (smartphone, laptop) and whether your TV model supports wireless networks. You can always check the latest compatibility information on the manufacturer's website, especially for models older than 2018.

1. Preparation: What to check before connecting

Experience shows that 60% of problems with connecting a TV to Wi-Fi are not related to the device itself, but to router settings or physical interference. Before accessing the TV menu, follow these steps:

• 📶 Check the coverage areaThe TV should be no further than 10 meters from the router (for the standard 802.11n) or 15 meters for 802.11acConcrete walls or metal partitions can reduce this radius by 2-3 times.
• 🔄 Reboot your equipmentUnplug your router and TV for 30 seconds. This will reset the DHCP cache and often resolve issues with obtaining an IP address.
• 🔒 Make sure there is no MAC filteringSome routers (especially TP-Link And ASUS) block new devices by default. Log into your router's control panel at 192.168.1.1 or 192.168.0.1 and check your security settings.

Pay special attention network operating modeIf your router broadcasts two networks simultaneously (2.4 GHz and 5 GHz), some TVs (especially older models) Samsung J series) can only "see" 2.4 GHz. In this case:

⚠️ Attention: If your Wi-Fi network name contains suffixes like _5G or -plus, this indicates operation in the 5 GHz band. Try connecting to a network without this suffix (2.4 GHz) or combine the networks in the router settings.
