4. Solving typical connection errors

Even with the correct router and TV settings, problems can still occur. Let's look at the most common errors and how to fix them:

Error: "Unable to connect to the network"

Reasons and solutions:

• 🔄 Incorrect password. Make sure you're entering the exact password that's on the router sticker or that you changed. Try entering it on another device (like your phone) to check.
• 📡 Weak signal. If the TV is far from the router, use Wi-Fi repeater or switch to the 2.4 GHz frequency (it has a longer range, but lower speed).
• 🔒 MAC address blocking. Some routers restrict connections based on MAC address. Find your TV's MAC address in Settings → Network → Advanced and add it to the whitelist on the router.

Error: "IP address not received"

This issue is related to the DHCP server on the router. Solutions:

• 🔧 Manually set the IP address for your TV. To do this, select "Network" in the network menu. IP settings → Manual and enter:

  IP: 192.168.0.100 (or another free one in your network)
  Mask: 255.255.255.0
  Gateway: 192.168.0.1 (your router's address)
  DNS: 8.8.8.8

• 🔄 Restart your router and disable the "Fast Roaming" feature in its settings.

Error: "No Internet Access" when connected to Wi-Fi

The TV is connected to the network but cannot open YouTube or Netflix? Check:

• 🌍 DNS servers. Replace them with 1.1.1.1 or 8.8.4.4 in manual network settings.
• 🔗 Proxy parameters. Make sure that in Settings → Network → Advanced Proxy server is disabled.
• 📵 Parental control. Your router may be blocking access to certain websites. Check the settings in the section Firewall or Access Control.
