# Windows – Missing Ethernet driver after downgrading to Windows 7

I've recently installed Windows 7 on a Lenovo M30-70 Notebook. It came with Windows 8 as default.

I delete all partitions when I downgrade/upgrade. My main issue is that I am missing multiple drivers, however, the Ethernet controller is the one I am in desperate need of.

Hardware ID's: PCI\VEN_10EC&DEV_8136&subsys_380617AA&REV_08
PCI\VEN_10ED&DEV_8136&SUBSYS_380617AA
PCI\VEN_10EC&DEV_8136&CC_020000
PCI\VEN_10EC&DEV_8136&CC_0200

I tried installing the Realtek driver for the Windows 8 version of the same model laptop but that did not install.

Can anyone advise on what I should do?

PCI\VEN_10EC&DEV_8136 = Realtek 10/100/1000 PCI-E NIC. Download and install the Windows 7 driver (Install_Win7_7088_07242014.zip) from Realtek.
