I prefer wired connections. Wifi is vulnerable from outside whereas wired needs physical access. Wifi is convient, but you suffer lower speeds and interference. I use wifi for my laptop, tablet, phone so I do use it. To make my connection more secure I make sure that no defaults exist have a 20+ character non dictionary wifi passcode with a mac filter, and no remote management options with a stong router passcode. Even if someone takes a handshake from me, good luck cracking
