I have been using Intel's Ethernet Connection I354 network adapter for a month or so on my desktop but it sudenly started to give me problems such as not detecting an ethernet cable. I have NO experience with Windows desktops because i have always had a prebuilt laptop at my disposal. I would really apreciate some help because it is incredibly annoying, especially because i have no idea what to do. My motherboard is the Asrock H97M Pro4 fyi
