What is the desired state? In other words, what problem are you trying to solve? Are you not getting an IP address at all, or are you trying to renew a new IP?
The IP address of your router? Your router is the go-between for your computer/laptop/device and the DHCP server of your ISP that assigns it an IP address. The IP address of your router should never change, 192.168.0.1. You would go to that address to get to the web service portal of your router to make administrative changes (block IP ranges, etc etc).
Are you trying to flush and renew a new IP address for your desktop/laptop/device? Because that is what ipconfig/release does. It will release your ipconfiguration to free up that IP address to be assigned to another device. If it is returning "media disconnected" then it sounds like your Ethernet or wireless drivers are not installed, or installed correctly. Is this on a newly OS-installed machine?
