I just built my own desktop, using a MSI P67S-C43 (B3) LGA 1155 Intel P67 SATA 6Gb/s ATX Intel Motherboard. After I installed WIndows 7, I could not connect to the internet. The Device Manager does not even have a Network Adapter group, and I was not able to find the onboard NIC anywhere in the Device Manager. I checked the BIOS, and the onboard LAN controller is enabled though.
Does anyone have any ideas about what the problem might be? Thanks!

Did you install all the motherboard drivers? Is it listed as an Unknown Device?
