After completing a scan, I have a device that had correctly detected the address/subnet/gateway/mac. By default its interface just shows the interface without a connection (just the default), but I'd like to have it connected. I open the interface properties and select the device I want it connected to from the drop down, then click OK. Immediately in the device properties I can see that the IP changed, and when I bring it up, the address is back to 127.0.01 and the subnet/gateway/mac are all blank.
