I bought a MP 2012 12 core. It is a little overkill for what I do (adobe) but I wanted something upgradable. I bought it thinking that I could hook my modem straight up to it and then run all my other devices off of it. I initially hooked up through my existing router as not to disturb the internet of my roommates. I tried today to hook up the modem to my MacPro and then back to my existing router. It seemed to work for a bit. When I called Applecare to trouble shoot it they recommended that I do not hook up straight to the modem and that I hook up to a router first. My internet was so much faster when I was hooked up to my modem first. How can they say that the Mac Pro has Airport Extreme in it if it should not be hooked up Just like the hardware version of the Airport extreme? ---------- Does the airport extreme that comes in a new Mac Pro really not have a firewall? How can it be advertised as such if it does not do what the Airport extreme in the box at local retailers do? Is it not a built in router in my MP? It seemed to work. Would hooking up my MP straight to my modem really leave my machine vulnerable??
