Securing that wireless network

I stumbled across thisĀ helpful article from Connected Home that explains how to secure a wireless network: https://www.connectedhomemag.com/HomeControls/Articles/Index.cfm?ArticleID=49176. The most important thing here is to enable WPA (or WPA2 if you have new hardware). Without this sort of encryption your network will remain as wide open as a crocodile at the dentist.
