I just built this system and when I power it up from cold the network card will not initialize. It won't even show up in the network manager. If I reboot the system it works fine. The drivers initialize and the network card works perfect. I downloaded the latest Intel drivers and played around with some of the power settings but it didn't help.

Right click mypc, then properties, device manager and then right click your network adapter. I don't have a pc in front of me now but i think that's the correct route. Any power saving options should be disabled.

I'm going to call Asus on Monday. I had already tried to disable all the options as you can see in the picture I posted. I also disabled the only LAN option I found in the BIOS. I can't believe that it's a bad NIC chip since it works perfect after reboot. There has to be some driver load issue on a cold startup.
I understand what you were asking qdemn7. I turned off those options and you can see by the picture that they're off. I also went into the BIOS and the only option is to either enable or disable the LAN chip, no other options. I called ASUS today and tech support is working to help me resolve the problem.
