Ok so i was doing some looking around on the web and i seen a video about a dude that piggybacked off someone and he only had a low/very low connection frist off how could you play games or download at like what 15 to 30 percent lol plus he had a wifi adapter is this true that the owner of the wifi couldnt know a lag on there wifi if you had a low/very low connection lol i just think why not just buy wifi and have a 100 percent but really how do people not notice this stuff the reason of this question is im getting wifi lol and im using a wpa but someone explain what this guy was doing thanks
