Network / Sharing :: Remove All Stored IP Addresses For Selected Adapters?

Using Windows 8.0 all up to date. I am trying to set up a DD-wrt router with a default IP Address of 192.168.1.1 which is also the default Gateway.

The previous router had 192.168.0.1 as the Gateway and I had given the laptop I am using a static IP of 192.168.0.10

When I try to access the DD-wrt it starts to work OK, but then hangs. I checked the "Properties" for the Network card and it keeps putting the old Static IP back. I go to Advance and Remove the old IP address, but it stuffs the old one back in again.

I tried using ipconfig /release but it says it can't do anything without the device connected. I feel like I am in a Hamster wheel from the Twilight Zone.

This is what "Properties" looks like after I make the changes.

192.168.1.11
255.255.255.0
192.168.1.1

As soon as I click OK for that dialog and the next one, it goes back to

192.168.0.10
255.255.255.0
192.168.1.1

If I go to "Advanced" both IP addresses are shown. I click "Remove" for the 0.10 and it removes it. Click OK twice and go back and the damned thing is back 0.10 and two IPs in the Advanced list again.

If I clear all adapters and set them all to "Auto IP address" I still cannot access the DD-wrt.

Is there some way to forcefully remove all stored IP addresses for the selected-Network adapters?
