Stream Video via router topic

Hi I have a Samsung smart TV wired direct to my wireless router
Using Samsung link on TV I could stream video or pictures to my TV via wireless network on my tab 2
But When I try to do it with my g pad it shows connect to TV when playing Video but when it connects and plays it switches Bluetooth on and plays via that
Is there a program that I can use to watch the same way as my as my tab 2
