I just built a computer with an Abit NF7 motherboard. It has a built in ethernet network adapter on the board. I loaded a wireless USB network adapter onto the system to have wireless capabilities, but now that I want to go back to a wired system, the LAN icon dissappeared from My Network Connections in Windows. Also, when I go into Device Manager, there is no Networking Card that is present. What do I do to be able to use an ethernet wire to access the internet? Do I need to download a new driver for my network card? It won't let me Create A New Connection for a LAN either. Thanks!!!
