Hi all I new. This maybe a silly question but trying to get my head round wiring or staying WiFi. Now with Wifi I have to put a password in to connect to my router to get internet. But with a wired connection just plug a ethernet cable in the back then to a switch and off to as many other devices as I want. So how is having a wired connection more secure? ( If someone was at the box down the road wouldn't they be able to plug into the wire that comes to my house, then gain access to all my computers connect to my router).
