Connecting Two Windows 7 PCs with a crossover cable

#1
Okay, I recently upgraded to Windows 7 from XP, (Completely wiped and reinstalled)
I'm having a problem connecting two PCs with a crossover cable. They're in the same domain, and they're in the same homegroup. My setup is like this:


My more powerful system is connected via straighthrough cable to the router, and the secondary system is connected via wireless card. I need the wireless card before Christmas, because I'm going to be using it in another computer for my brother's room. I have two network interface cards in the main system, and one physical in the secondary. I've attached them via crossover, and all I'm getting is a response of that basic network as a public and unidentified network. I've tried searching for resolutions, and I need to say this:

The networks names and interfaces are not clickable. Where it says "Public network" is just text, I can't click it to change it to a home network. Anyone who can help, PLEASE do.

I'm thinking of calling Microsoft soon if I have to.
