I do not know which one is my Ethernet Controller. 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.

Looking at the other devices in Device Manager, there are several entries for Intel 82801G ICH7 family ..., so I guess that is my chipset model.

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.

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.

I went to intel download center, there also I could not find any driver for ethernet controller for the specific chipset 82801G ICH7 family.

Any help will be greatly appreciated, as I need to connect to internet from the Windows 7 machine.

Thanks.

EDIT: Looking at the Hardware Ids of the Ethernet Controller, there are 4 hardware ids:

PCI\VEN_10EC&DEV_8136&SUBSYS_813610EC&REV_03
PCI\VEN_10EC&DEV_8136&SUBSYS_813610EC
PCI\VEN_10EC&DEV_8136&CC_020000
PCI\VEN_10EC&DEV_8136&CC_0200

Why are there 4 hardware ids? I googled for the 1st hardware id. I found it belongs to "Realtek RTL8103E Family PCI-E Fast Ethernet NIC". But I could not find the driver for even that in google. As earlier, most sites are torrent sites or require their own downloader to be installed.

Any help will be greatly appreciated, as I need to connect to internet from the Windows 7 machine.

Thanks.

What is the make and model number of the computer or is it a home built or custom built?

When I did a Google search for PCI\VEN_10EC&DEV_8136&SUBSYS_813610EC I got Realtek RTL8168/8111 PCI-E Gigabit Ethernet NIC. I didn't see anything about Intel.

If that is what it really is, the driver for Win 7 is here:

It is a custom built computer. I ran CPU-Z and here are the results:

Motherboard Model: OEM, Manufacturer: OEM, Chipset: Intel P35/G33/G31, Southbridge: Intel 82801GB (ICH7/R),
BIOS Brand: Phoenix Technologies, Version: 6.00 PG

When I boot computer, the first screen which comes displays "MERCURY". So I guess the motherboard manufacturer is Mercury. Opened the PC cabinet. On the mainboard, Mercury is written. Between the CPU fan and RAM slots, there is a string "G31CCL2-07", I guess that is the motherboard model. Don't know why CPU-Z is says motherboard manufacturer and model is OEM!!

Searched google for G31CCL2-07. Some links are there, but they require me to download their own download managers, which is risky. Searched Mercury site for G31CCL2-07, but could not find any driver.

I am running out of ideas!

@ZTrucker, I tried the link you gave, but that driver is not being accepted by windows. It still shows Ethernet Controller with an error sign..

I'm not having any luck either. I ask some of the other folks here to take a look and see if they can help.
