Windows 7: Realtek LAN Driver disappears

Windows 7

I feel your pain! I was so frustrated with that driver issue. I installed a really old pci network card and have had no issues! very strange indeed! hopefully MS fixed this issue in the RC !

I've had this issue crop up a few times too. It usually shows itself while doing a Windows Update and then reboot..poof...nic is there but not connected. Happened after this mornings update of windows defender. I did a rollback/sys restore and all is well.

Onboard 1gb nic

Win7 7100 x64 shows it as NVIDIA Nforce

Maybe this issue needs to percolate a little.

Windows 7 x64

I've had a problem too the Realtek LAN driver and this system I just upgraded (Gigabyte GA-MA790XT-UD4P). I installed Windows 7 7100 and the stock Win 7 drivers worked fine. Windows update showed a new Realtek driver, so I let it install. The NIC no longer worked.

I uninstalled via Device Manager and went to Gigabyte's Web site and downloaded the LAN driver for the motherboard (for Vista x64). This driver didn't work either.

I uninstalled again and let Windows install the stock driver. That got the NIC working again.

I then found a driver (just the INFs) at the Realtek Web site that worked (version 6.218 for Vista and Win Server 2008).

hi ya Wayward,

When I install the RC I will try your suggestions... I have a Biostar mobo and I had the same issue you had with Gigabyte. I will check out the Realtek link in your post and try that same driver version in the RC and see if it works for me as well.

thanks for update

Realtek LAN Driver disappears with windows7

I had the same problem my ethernet just disappeared from device manager a few days after windows 7 clean installation. I found 2 problems helped. The first thing I done was to check the power management settings in device manager. Make sure the option ' allow the computer to turn off this device to save power' is not ticked. That didnt make my adapter reappear but when I googled the problem it was something other people had experienced so I changed the power setting just in case, to avoid any future problems. What did make the ethernet reappear was there is apparently a bug causing people to lose their hard drive and ethernet on Asus boards when using windows 7. The windows 7 loads the bios and cant see either of the HD or ethernet, I was advised to try swapping over my sata cable to sata 1 or 2 connector on the board (if its connected to sata 1 swap it onto 2 and vice versa). I followed this procedure and rebooted and hey presto ! the ethernet was back in device manager and the connection active again and also no more start up bios error messages about a missing hard drive. Hope this helps folks!
