In attempting to update an UPS network card I think I have corrupted the firmware. I am planning to use nmap and other tools to try and probe the card. How should I configure the NIC on my laptop? Should I use a fixed IP which may or may not be relevant to the UPS card or DHCP, in which case should I keep my wifi connection. My concern is I do not want to scan my wifi and the wan, I only want to scan the card connected by copper to my laptop. Hope my explanation is clear.
