I while ago I bought a webcam, plugged it in and entered my wifi password. I little bit later I realized that it had reconfigured my router and was broadcasting to the internet. Wow, I'm all for easy to install, but that's crazy. I couldn't believe that my router was configurable automatically without entering the password.
