TCL Roku losing network connection.

Everyday when I streaming I lose connection and my what I'm watching keeps dropping. I reconnect on the TV but by the next day it starts again. It looks like my TV is connected to the router I am just losing internet from there. I am having no problem connecting to the internet from any other devices.

Router: Arris DG3450A

TV: TCL 6-Series R625

I'm connected to the 5GHz network on my router. The router is roughly 20 feet away from my TV.
