Always been an ethernet man myself, but does anyone actually game over WiFi? When I tried it back in the day it felt slower and less stable than a wired connection. How is it these days? How do speeds compare to a wired connection?
You can, but don't..
Avoid powerline too.
My WiFi is just as good as my gigabit ethernet, but then I do have a decent router (Asus RT-N66U).
