Error Releasing/Renewing IP

Hello! I am trying to change my IP, I am using Win8, I type in ipconfig/release and it says "No operation can be performed on Local Area Connection*11 while it has it's media disconnected"


I did "netsh interface show interface" and I get

Admin State State Type Interface Name

Enabled Disconnected Dedicated Ethernet
Enabled Connected Dedicated Wi-Fi

right click the network icon in the notification area of the task bar. Open network and sharing, Click on change adapter setting. select the network adapter your are using right click/Disconnect. Your router should be handling the IP assignment. From this location you can disable and enable all your network adapters.
