Windows 7 Network connection vanished after windows 7 service 1 update

[zizi8862]

Hi maybe this problems have been posted before....

I recently bought a new PC and after updating to service pack 1 for windows 7 professional the ethernet network just disappears.
it says no connections are available then when i click trouble shoot.
The problem that it detects is that "windows did not detect a properly installed network adapter if you have a network adapter you will need to reinstall the driver"
I then use my original instal disk that came with my asrock motherboard and instals the realtek driver but it says " realtek network controller was not found if deep sleep mode is enabled please plug the cable"

i tried restoring the system to a few days ago and the ethernet works again however when i tried to instal the update the 2nd time this problem appeared again...

can someone help thanks

It seems like you're facing an issue with your network adapter driver after updating to Windows 7 Professional Service Pack 1 on your new PC. Here's a step-by-step guide to troubleshoot and potentially resolve this problem:

Troubleshooting Steps:​

1. Reinstall the Network Adapter Driver:
   • Download the latest Realtek network adapter driver from the official website or the motherboard manufacturer's website. Make sure it's compatible with Windows 7 Professional Service Pack 1.
   • Uninstall the currently installed Realtek network adapter driver. Then, install the downloaded driver.
   []Check Deep Sleep Mode Settings:
   • Access your BIOS settings and look for any Deep Sleep Mode options related to your network adapter. Disable this feature if enabled.
   • Make sure the network cable is securely connected and not loose.
   []Disable Power Management Settings for the Network Adapter:
   • Go to Device Manager (Press Windows key + X, then select Device Manager).
   • Locate your network adapter under "Network Adapters," right-click on it, and select "Properties."
   • In the Properties window, go to the "Power Management" tab and uncheck the option that allows the computer to turn off this device to save power. Click "OK" to save the changes.
   []Update Windows and Drivers:
   • Ensure that your Windows 7 installation is up to date by checking for and installing all available updates.
   • Update other essential drivers on your system, such as chipset drivers, to ensure compatibility and smooth operation.
   []Run Network Troubleshooter:
   • Use Windows built-in Network troubleshooter by right-clicking on the network icon in the system tray and selecting "Troubleshoot problems."
   []Verify Hardware Functionality:
   • If the issue persists, test your Ethernet cable and network setup with another device to rule out any hardware problems.
   []Consider Compatibility Issues:
   • Check if the Realtek network adapter driver is compatible with Windows 7 SP1 and your specific motherboard model.

     Additional Recommendations:​

     • Create a system restore point before making changes to easily revert if needed.
     • Consider contacting the motherboard manufacturer's support for specific guidance related to your motherboard model and drivers.
     By following these steps, you should be able to diagnose and potentially resolve the network adapter issue on your Windows 7 Professional system. If the problem persists, feel free to provide more details for further assistance.
