My Ethernet/ LAN won't connect. It says the network is an, "Unidentified Network". I've searched the internet, I've uninstalled and re-installed my Ethernet controller, I've also tried using command prompt and doing a, "ipconfig /release" and then an, "ipconfig /renew" and nothing has worked. It also says in the troubleshooter that i have an, "Invalid IP Configuration". I've tried many other methods. My computer is an Asus G75VW Notebook with Windows 8 64-bit. The critical updates that installed right before the problem was for Microsoft Office 2010.
