I have a Smart TV Model 40PFL6606D/77 and I can't connect it to Net TV service. When I try to access to the service it says "Conectando..." (Connecting...) forever.

I have updated the firmware today to the last one.
It is connected to the home network using UTP cable. It has IP, maks, DG, DNS, etc. I do can connect PC to the TV using Wi-Fi Media Connect. My PC can access to Internet correctly.
Both PC and TV are connected to the same network.
I tried also using Wi-Fi dongle but I coudln't connect.

Do you know if Net TV service is working? May a have something wrong in configuration?

Thank you very much in advance.
