It also really helps to be wired if you download videos to the net like Youtube. WiFi often just doesn’t cut it. Too many halts and drop outs.
Eventually I’m going to run Ethernet to the Roku’s. They are in a tough location but it’s probably a good idea.
We have an Xbox, PS3, 2 tablets, 2 desktops, 2 laptops, 2 rokus, 2 android phones running on wireless. At any given time we are playing a game and streaming at least one video source (netflix, amazon, youtube, etc). No problems. Runs like a charm.
WiFi doesn’t cut it fr MMO gaming either.
Also, when my wife downloads big programs they recommend you to be connected to wifi router.
