I installed the update for Realtek RTL8168C/8111C Family PCI-E Gigabit Ethernet NIC (NDIS 6.20) through Windows Update (released on th 30th April) and it simply broke the network (no longer detects the wired network). I had to uninstall the driver and make a Search hardware changes to install the default one Windows 7 brings (also NDIS 6.20). So please, don't offer this update in Windows Update (this is not the first time it happened to me) anymore. PS: Windows 7 RC x64

I got this problem and my driver is Realtek RTL8101 Family PCI-E Fast Ethernet NIC (NDIS 6.0).The driver caused losing Internet connection after 10 or 15 mins. I uninstalled the new one and installed the old one. The old driver so far works fine.Thank you

In my case this is also a problem for me in Vista so I think it is a general problem within the driver package from Microsoft.

HiJust an update.The problem has not been fixed yet, even with the old driver.I'm still stuck with this annoying problem.Thank you.

In my case for a single Ethernet port the device list shows upto 20 such ports each time I upgrade the driver. So when Win 7 starts I have to manually first disable all ethernet ports and then enable one again to work ( ususally the 2nd or 3rd port) in order to connect to my home network/internet. I have tried various tricks like deleting all entries, uninstalling driver, etc. etc. I had the same problem in Vista and I was hoping that this would disappear once I moved to Win7 - but no joy. Each time I reinstall the driver a few new more ports get visible with status of cable disconnected etc.

I have a ASUS P6T, with built in NIC, installed this update, and lost all networking. I actually had to go back and use an older system recovery point to get my networking back. I did this twice, because it was still listed in Windows Update after the system recovery.Mark
