Strange issue just came up and thought I'd ask for advice. I'm staying at a hotel connected to its wifi network. For the last few days, I've been getting random Airport Setup popup windows, which I've never seen before, and so I've just closed out of the window without continuing on. Anyway, this morning, my wife calls me and tells me that my another guest in the hotel calls our room and says that he can see all our files on the network and that everything is compromised. What the heck?! I told her to shutdown the MBP. But does anyone know what is going on?
