Posted on by admin



As I’ve noticed a fair bit of visitors interested in my post of Windows 7 and Network Controller Deep Sleep Mode problem, I thought I should write a “clean” version of the post (basically the fix for the problem minus my ramblings 🙂 )

This package installs the software (Ethernet Controller driver) to enable the following device. Device name - Ethernet Controller Device name in the Device Manager - Realtek PCIe GBE Family Controller. Common Stock Quote. Shareholder's meeting. Dividend and Capital Information. Contact for stock transfer and register. News about Realtek( Company code:2379).

Realtek Ethernet Problems in Network and Sharing I have tried to set up Win 10 on my desktop,however, Win 10 conflicts with my Realtek Ethernet, I can not make the program to connect with the net, however, my lap top coneects (via WiFi) with no problems. Realtek’s 2nd Generation 2.5G Ethernet solutions are the lowest power consumption (Ethernet products. Option Two: Change Settings in Network Adapter Properties. 1) Press Windows key and X at the same time, then choose Device Manager. 2) Locate and click the arrow to expand category Network adapters. 3) Then right click Realtek PCIe GBE Family Controller option and chose Properties.

The problem starts when the computer goes into sleep/standby mode, a few components of the PC including the network controller (or adapter) are turned off. The issue occurs when the PC wakes up and power to everything is restored. The network controller doesn’t come on and as per Realtek installation message:

The Realtek Network Adapter/Controller was not found.
If Deep Sleep Mode enabled Please Plug the Cable

The best fix is to reset the motherboard and the best way to reset your motherboard is to remove your RAM chips. Leave them out for some time (in my case 30 seconds) and put them back in. And that is all! The motherboard will be reset and the network controller will come out of deep sleep mode!

Note: If this doesn’t work, leave the RAM out for good 10 minutes. Leaving the RAM out longer has worked for some people (see comments below).

Note 2: For laptops, removing the battery for 5-10 minutes has worked for a few.

Cards

Note 3: If nothing works, turn off the system and plug in a external hard drive (or a USB thumb drive) and then turn the computer on. Once on the desktop, Windows will try to install the external hardware. This, in some cases, has worked and wakes up the network controller.

Note 4: Some people have reported that “Loading Default Settings” in the BIOS solves the issue as well. You will need to go into the BIOS at start up by pressing the Delete key (can be F2 or some other, please check the message at the start of the screen). Once in BIOS, you can press F10 to “Load Default Settings” (If you don’t see that, look for a button saying that. It is usually around the “Save & Exit” Button). Once loaded, hit “Save & Exit”. This will restart your computer and some people have reported this fixes the issue.

Once you have it working, to make sure the network controller doesn’t go into sleep mode again, try this:

  1. Open Device Manager by:
    1. Go to Start
    2. Click Control Panel
    3. Choose System and Security
    4. Click Device Manager (under System)
  2. Open Network Controller properties by:
    1. Double-click Network adapters to expand it
    2. Double-click the Realtek Network Controller
  3. Turn off Deep Sleep mode by:
    1. Choose the Power Management tab
    2. Untick “Allow the computer to turn off this device to save power”

Doing this will make sure the network controller is not put in to sleep mode till someone fixes the issue!

Finally, if something does work you please post the Motherboard/Laptop model and the method that worked to help others!

Users report that their Realtek PCIe (Ethernet) family controller stopped working randomly after upgrading to Windows 10. There are still no answers from Microsoft or Realtek as to why. this could have happened, and the situation is so random that there are many solutions that can be useful in different cases.

If this is a problem that you are currently experiencing, please follow the instructions below to solve it yourself.

Uninstall and download the latest version of the network driver.

To do this, you will need to use another device to download the latest network drivers for your motherboard. Once you have downloaded the drivers, transfer them to your Windows 10 computer and follow these steps:

  • Press the Windows + X key on your keyboard and go to Device Manager.
  • Find the network card. When you find it, right-click on it and select “Delete”.
  • In the “Uninstall” window, select “Uninstall the software driver for this device”.
  • Follow the on-screen instructions and reboot your computer after the uninstallation process is complete.
  • After restarting your computer, go back to Device Manager and click Scan for hardware changes.
  • This reinstalls the standard network drivers.

Troubleshoot your hardware

Sometimes a Realtek Network Controller Not Found error is caused by problems with the network card or RAM. Just check your hardware.

Step 1: Turn off your computer completely and disconnect the power cord. If you are using a notebook, remove the battery.

Step 2: Open the computer case or remove the notebook cover and remove the RAM from the motherboard.

Step 3: Let the RAM stand for half a day to interrupt the network controller’s deep sleep mode.

Step 4: Insert the memory chip back into your computer.

Step 5: Connect the power cord and battery, turn on the computer and see if the error has disappeared.
