I have fujitsu Esprimo p 3510 with Realtek RTL8168/8111 PCI-E Gigabit Ethernet NIC, sometimes is showing disconnected from the network although the cable pluged,but when i boot from windows xp it is fine , is it a driver issue with windows 7 or Realtek RTL8168/8111 PCI-E Gigabit Ethernet NIC is not compatible with windows 7,

Hi! there , its definitely a case of incompatible hardware/driver with windows 7, the card working smoothly with Win XP (without any physical settings change, wires,NIC, etc) makes it  evident that there is an issue with the hardware(NIC) or its driver or its not compatible with Windows 7. Try reinstalling Drivers or contacting Realtek support for a compatible driver.
                                                   Try the windows update from windows website and make sure you select all updates to be downloaded(even the non critical ones), Windows generally dont download non critical updates by default, so check it manually.

There also exists a chance thet you havent configured your Network properly in Windows 7, may be thats causing the disconnect.

Regards,
Sujith

It is either your card, the cable or wherever the cable is plugged into.. if it is router try a different port on the back of the router.. you could have an intermittent short/open in your ethernet cable same thing with the ethernet card. It is a process of elimination.  If the ethernet adaptor  is not built into the motherbaord then try re-seating the card.. could be a loose connection in the cable.. do you have an always on connecftion to the network? or is it a vpn? and you have to reconnect to the vpn periodically?

Sounds like a driver issue. Try updating the driver from the manufacturer's site, or via Windows Update. Good luck!

Hi

I have had the same problem. All I needed to do was uninstall the NIC driver, Restart the PC & reinstall the driver for the network card.
