Bought a Samsung UE49NU7500 only 3 months ago. Everyday the WiFi disconnects and there is no issue with my router (It engineer), I simply have to go to settings and reset network then reconnect to WiFi typing password each time.
I reset everyday now, I watch a lot of Netflix.
Before posting here I tried heaps of solutions.
