WiFi for Nvidia Gamestream

[IAR117]

Hi, I really didn't know which topic to put this is in, so don't go on about me putting it in the wrong topic.

Recently I was looking up the requirements for gamestream as I own a shield tablet. Most people just give me the same"GTX 650 or better answer." However Nvidia claims that this technology is lag free, or close to it. I then became curious about WiFi recommendations, however all I got was"Get a dual band router."

Basically my question is will my WiFi- 18 down and 1 up- be ok for gamestream

Also here is my router

Thanks in advance

 

Sorry forgot to add this, I will be using this mostly on other networks, outside of my home in my grandparents house which has 2-3 up and 30-40 down and my pc is conencted via ethernet
