Is Windows 7 sleep mode supposed to turn off the NIC card?

Here is my problem: I have a Dell Optiplex 745 with Windows 7 Pro installed on it. When the computer goes to sleep, the NIC card also turns off. I know this because when coming out of sleep, I see the network icon on the bottom right hand corner with a red X on it. After maybe 15 seconds, the connection is restored and I can see my network and network drives again.
My question is, is sleep mode supposed to turn off the NIC card? I did not find anything that says it isn't supposed to turn off the NIC card.

I have updated to the latest BIOS version from Dell. I have the latest NIC card driver (Broadcom 57XX gigabit) from Broadcom. I unchecked the box that says "allow for comptuer to turn off this device to save power". I even tried the registry hack found in this thread (https://www.experts-exchange.com/Software/Development/Management_Debug/Deployment/Q_25010351.html) and it did not work. There arent many options in BIOS but I did change the sleep power setting to S1 (saves least amount of power).

I am out of ideas to try. Or is sleep working correctly and I am just wasting my time?
