I found it belongs to 'Realtek RTL8103E Family PCI-E Fast Ethernet NIC'. I went to intel download center, there also I could not find any driver for ethernet controller for the specific chipset 82801G ICH7 family.Īny help will be greatly appreciated, as I need to connect to internet from the Windows 7 machine.ĮDIT: Looking at the Hardware Ids of the Ethernet Controller, there are 4 hardware ids: I did google search for at least 1 hour, most links are pointing to torrent sites or require me to install one of the downloader softwares, which are fraught with risk. Looking at the back of the computer, there is no external network card, the lan cable is going to the motherboard provided LAN slot, so it is the integrated network adapter. Looking at the other devices in Device Manager, there are several entries for Intel 82801G ICH7 family. It was working fine in Windows XP, but after installing Windows 7 (clean install), it is not able to detect driver for Ethernet Controller, so I am not able to connect to internet.

I do not know which one is my Ethernet Controller.
