Hello, i recently bought a Samsung UE50RU7102KXXH. This model has an mt7668u wifi adapter integrated. This adapter is dual band and it supports both 2.4GHz and 5GHz wifi according to the manufacturer. The problem is my tv only discovers 2.4Ghz wifi signals. Changed 3 routers and any imaginable setting, with no luck. I called the local (Greek) Samsung support and after some generic tips (change your router etc) and a denial to connect me to a technician they concluded that the tv supports only 2.5GHz signals and thats that. Anyone has any clue about this? Is it possible that even thought the tv's wifi adapter has the capability, i am being denied of using what i paid for from samsung?
