Specs: Windows 7
Hello
I have a Lenovo G430 series laptop. When I connect ethernet cable to RJ45 port then there are two lights are blinking one is green and other is orange. But I did't get connected with the laptop.
I tried to install LAN driver from gigabyte, but it is still not working. My wireless connection is OK.
At device manger I go to Network Adaptor , it is only showing one broadcom 802.11g.
When go to Network Connections in Network and Sharing Center it is only showing wireless connection.

"I tried to install LAN driver from gigabyte"

Why Gigabyte? Only Lenovo have the correct drivers for Lenovo laptops. Gigabyte has nothing to do with your laptop. Anyway, it's not a driver issue.

If Device Manager isn't showing a wired connection network adapter, and there are no error symbols in there, it means the wired connection adapter is faulty. Windows can't find it because of the faulty component.

Contact Lenovo to have it repaired.

I had a problem with my internet cable, which turned out to be that my cat had bitten it and I needed a new cable. Even if you don't have a cat, if you have an extra cable, you might want to try it. It's a cheap and easy fix, and cables do go bad; but continue to make the lights blink.
