So I was messing around today and opened up this program called Apple Remote Desktop on my Mac. (It pretty much monitors and manages all the computers on my network.) So I have all my computers set to have Static IP addresses increasing from 2 (ex. 192.168.1.2, 192.168.1.3, 192.168.1.4, etc.) So today I noticed a device label 192.168.1.105 (This number was automatically assigned by the router) I went around the house to make sure no one was using a work computer or a friend had brought over a laptop... Nothing was on... So in a panic I shut off the Wifi and the user was dropped. I couldn't figure out how someone could have gotten through my WPA password protection? So I just left the Wifi off for the night... Hopped on my Wii a few minutes ago to check out the weather channel and it said it could not connect to the network.. I had forgotten the Wii connects to my wireless router... Turns out I am just a paranoid dummy.
