I recently formatted my HDD and reinstalled Windows 7 on my PC. However, I can no longer connect to the internet through Ethernet (no WiFi option). I've changed the ethernet cable but to no avail.
I have a Asus P5N-e SLI motherboard, and I have installed the nVidia nForce 650i SLI driver which includes Ethernet drivers. When going to Network Connections in the control panel, there is nothing showing.
I don't have the motherboard installation disc any more. I've tried googling the issue and a lot of answers suggest installing the drivers which I'm sure I've done.
In the device management, there is an unknown device with a yellow exclamation mark which I'm assuming is the network card.
Any help would be great as I'm running out of ideas! Thank you
