The Realtek Network Controller was not found. If Deep Sleep Mode is enabled Please Plug the Cable.
This just happened yesterday and we tried all the posted remedies. Pulling out the RAM chips for up to 10 minutes, unplugged the power supply to the motherboard, fiddled in the BIOS settings to disable/enable the on-board LAN, patted our heads and rubbing our belly. Nothing worked, same stupid error. (Sure, pulling out the RAM chips and such might work for some of you, but didn’t work for us)
Short of having to re-image the drive, we decided to strip out all the cards off the motherboard. Pulled off the USB card, video card, sound card, PCI Express card and the RAM chips. Cleared off the motherboard! (we left the power supply cables attached)
Put back in the RAM chips ONLY and booted it back up. Ok, the realtek network controller is now loading correctly. So we started adding back the cards to identify the culprit. (Which turned out to be The PCI-Express to PCI Adapter Card)
We were unable to reassign the IRQ for that device so we just left it out and VOILA! SOLVED.
Once you get it up and running again be sure to do the following:
Open Device Manager:
1. Go to Start
2. Click Control Panel
3. Choose System and Security
4. Click Device Manager (under System)
Open Network Controller properties:
1. Double-click Network adapters to expand it
2. Double-click the Realtek Network Controller
Turn off Deep Sleep mode:
1. Choose the Power Management tab
2. Untick “Allow the computer to turn off this device to save power”

I had this problem with a Realtek on a Dell Vostro 3700. Tried most of the methods recommended from internet searches. The one that worked for me was very simple -in device manager right click on network adapters and select “scan for hardware changes” -this found it -then select update driver-install new driver from internet.

Thanks David. Good call to update driver first to see if that fixes the issue.

This is a very common problem with very varied solutions. I have been fighting with this problem on a Gigabyte MB without any sol to date having tried almost every solution found on the internet.

Didn’t work for me. Been having this problem for quite a while. After sleep mode, it can take anywhere from 10 seconds to 3 hours for network adapter to start. Says that there is no wire plugged in, but cabling is fine.

What didn’t work? Did you remove everything off your motherboard? Cards, memory etc? Once it wakes up do you Turn Off Deep Sleep Mode as posted above?

there is no network controller in device manager, when i checked network properties “Local Area network ” is missing , any idea ?

Check http://support.microsoft.com/kb/825826 to troubleshoot missing network connections. (presuming you have XP) Otherwise, sounds like the network card has failed. Replace it.

Install a new network card in an empty PCI-E slot and forgo Realtek.

I solved this problem like this:
– Disable Intel SpeedStep (if any) in BIOS
After I did that Windows just installed the driver when I booted the next time.
