Maybe it’s reset back to defaults which is DHCP falling back to APIPA if there’s no DHCP server to be found.
If this has happened and you had static IP settings previously you’ll be on different networks and you get those kinda symptoms, card visible but you can’t do much with it.
Try unplugging all connections to the card except a cable directly between the primary port (left Neutrik socket) and your laptop.
Configure your laptop to DHCP (automatically acquire IP address) and it should be able to connect to the card so you can reset the IP settings, then you can cable back up as usual.
Let us know how you get on.
