Symptoms: your computer has a static IP. However, the ipconfig shows no IP (Media State - Cable Disconnected) while the network cable is disconnected.
Cause: this is by design. If you have some software using TCP/IP whiteout connecting to a network, you may setup it manually.
Symptoms
when attempting to use ipconfig /release or renew command, you get "No operation can be performed on the adapter <xxxxx...> as this connection has its media/cable disconnected.
Causes
1. The network is up-plugged or no NIC.
2. You are using static IP.
