• 🔄 Router operating mode: In the settings ASUSWRT must be enabled Wireless Router Mode (Not Repeater or AP Mode).
• 🔒 Encryption type: Televisions Sony Bravia 2018-2020 do not connect to networks with WPA3 - use WPA2-PSK.
• 📡 Channel and frequency: On 5 GHz some models LG lose connection. Try 2.4 GHz or channels 36-48 on 5 GHz.

Also check:

• ⚡ Router power supply: Plug it into a UPS - power surges reset the settings DHCP.
• 📱 Other devices: If 10+ gadgets are already connected to the router, the TV may not receive IP address. Disable unnecessary ones.

⚠️ Attention: If your router ASUS works in mode AiMesh (mesh network), the TV can only connect to the main node. Secondary nodes often block multimedia traffic.

2. Method 1: Connecting via WPS (fastest)

Technology WPS (Wi-Fi Protected Setup) allows you to connect devices without entering a password. Compatible with all models. ASUS with a button WPS and televisions no older than 2015.

2. Go to Wireless Network → WPS.
3. Activate PBC (Push Button Configuration) and press Start.

The WPS button on the router is flashing green|The TV shows the "Connected" status|The IP address is displayed in the TV network settings|The connection speed is at least 50 Mbps-->

⚠️ Attention: Some TVs Samsung (series JU6400, KU6000) do not support WPS On firmware versions older than 2019. In this case, use method 2 or 3.

3. Method 2: Manually enter the Wi-Fi password

For routers ASUS with firmware ASUSWRT-Merlin (For example, RT-AC86U):

• 🔧 Go to Local Network → DHCP Server.
• Make sure that Enable DHCP server activated.
• 📌 Book now IP address for TV by MAC address (you can find it in the TV network settings).

4. Method 3: Connecting via Ethernet (for stability)

If Wi-Fi is slow or often turns off, use LAN cableThis method guarantees maximum speed (up to 1 Gbps) and minimal delays for 4K HDR and online games.
