A:Answer You don't need a Roku with the Smart tv if you have a wireless router. The tv will automatically pick up the router signal so you can access Netflix, Hulu, and the other apps on the tv. You will just need the router's password, which is the WI- FI Security Key. This info is on your router or paperwork that came with it. Very easy to enter this info on the tv as it goes step by step in the initial set up.
