I was recently debating / arguing with someone about if Wi-Fi was just as good wired for connection for slow internet. The speed we were debating over is only 15mbit/s pushed over the 5ghz band. The computer is sitting also right beside the access point. For the sake of simplicity ignore how easy it is to just plug in to the access point. Obviously at higher speeds a wired connection would be superior, but at speeds this slow would it really make a noticeable difference to be plugged in?
