Ive looked at all the options for the best connection with my internet. Ethernet is better then most of my wifi speeds, but i only have 1 cable for 2 consoles (ps4 and xbox 1) the cable didnt really work on my ps4, it stopped giving me internet, so i checked it and it was starting to melt (that was a shock, it never happened on xbox). It took ages to take out (30 mins of trying to unplug it, damm awkward ps slots!), and plugged it in my xbox. Works fine there. Now ps is on my fastest wifi, and i rarely have problems. Sure the lags there, but its there with the ethernet as well. In fact, wifi seems to be better.
