So, My Network got Hacked

TL;DR; Seperate your data / laptop / desktops from your IoT devices. Came home from a conference, you know, one of those I'm not allowed to name. Suspicion Anyway, I was working the next day and suddenly, I had no internet access. It seemed odd, as my Sonos continued to play music from SomaFM. So, I went to another machine and it had access, just my work machine. I rebooted my work Macintosh, and still no access to the network.
