"the realtek network controller was not found. If Depp sleep mode is enable diconnect the cable"

Firstly, check it's not become disabled in the BIOS.  You might also want to consider resetting your BIOS to factory defaults (as long as you know the details of any non-default settings that you'll need to reconfigure after!)

It can also happen that motherboard component dies.  I've seen a dead NIC on a Dell desktop PC board before.

What you could try is using a bootable Linux CD (eg Ubuntu) and see if it can see and use the NIC.  If it can, then you know the hardware itself is OK.

I'd try this NIC controller on another machine and see if it is recognised there.  If it isn't then return it to Dell.

One more thing.  If it's there on boot but disappears later, there are some weird power-saving things that make the NIC appear completely disconnected on some newer laptops.  Your post does mention "deep sleep" - did you do what it says - does the NIC come back?
