No local network connection option

[sgtpeper67]

We've got our machine plugged directly into the modem and it previously worked fine. At some point something happened and now I have to connect via wireless. When I go the Network and Sharing Center and click "Change Adapter Settings", the only thing in the folder is "wireless network connection". I know the plug in connection works because I tested it on a laptop. I can even find where I can "opt in" or enable a LAN connection.

Any advice?

Thanks!

your PCI card could of went bad. look in device manager under network adapters and see if you have a PCIe family controller and your wireless adapter listed. use scan for any changes in hardware. need more info on what system you have.
