Anyone who says Wifi is internet is a perfect example of why this is misinformed. And Ive heard it elsewhere as well
Wifi does not mean internet. All Wifi is , is a wireless network connection. If you connect to the network and there is internet on it AND you have the encription password then you will have internet. So if you neighbor has Wifi and it goes into your house (and frequently is does especially in a place like Brooklyn) and you have wifi on your laptop, Unless you have the Wifi Password (or the neighbor has unencrptyped internet) it is useless to you or anyone else
