I just received my new laptop yesterday. I used the Ethernet/wired connection just fine. Today, I have no connection, but can connect using wifi. The Ethernet connection does not show up in the Network and Sharing Center. Where did it go and how do I get it back? 24 hours with 8.1 and already I have these problems. What happened to the Ethernet adapter. All that shows up is the wifi. Thank you for your help.
