My network connections only show my wireless connection (which works fine), but the LAN connection will not show. When trying to create the connection using the "Create a new connection" option, it tells me that my connection should already be configured and working. I have tried all of the options that ironside suggested, but I still do not see my LAN connection, and attempts to connect with an ethernet cable are unsuccessful. I have no idea how to proceed, except by reformatting, but I do not have a CD drive on this laptop, nor do I have the proper OS install discs.
