First i want to describe the Situation:
We got a Telekom Speedport at the ground floor at my dads office.
I got in my room (in the third floor) a TL-WR1043ND. Those to routers are linked via Lan because the distance for wifi is to large.
Now i got a AC3200. I want to you the AC3200 instead of the TL and use the TL as a Repeater.
I want to us the TL in combination with the TV.
I Have a Computer Screen and a TV-Box as a TV. so i need to link the TL with the TV box via Lan.

Is this possible?

here a small outline of our house and the situation





thank you for your help!
