3. If the router only distributes 5 GHz, also enable 2.4 GHz in its settings (section Wireless → Basic Settings).

6. Alternative ways to connect to the Internet

If connecting via Wi-Fi is not possible (for example, due to incompatibility or a weak signal), consider alternative options:

🔌 Powerline adapters (Internet over electrical wiring)

These devices transmit the internet signal via the electrical network. Simply connect one adapter to the router and the second one to the TV (in the same outlet). Speeds reach 500-1000 Mbps, and the stability is higher than that of Wi-Fi.

Pros:

• ⚡ Stable connection without packet loss.
• 🏠 No cabling required.

Cons:

• 💰 Additional costs (from 2000 ₽ per set).
• 🔌 Depends on the quality of the electrical wiring.

📶 Mobile Internet (USB modem or smartphone)

Some TVs (Samsung, LG) support connection via USB modem (3G/4G). You can also share internet from your smartphone:

1. Turn it on on your phone Modem mode (or Access point).
2. On your TV, select the created network and enter the password.

Restrictions:

• 📶 Low speed with a weak mobile network signal.
• 🔋 Smartphone battery drains quickly.

🔗 Direct connection to the router (if Wi-Fi is not working)

If the TV's Wi-Fi module is broken, but there is a port Ethernet, use network cableEven if the router is located far away, you can run the cable along the baseboard or use flat cable (less noticeable).
