Using a ethernet cable to transfer files?

Solution
If you don't have a router to assign ip addresses by DHCP, you can directly connect two computers by an ethernet cable in something called an "ad hoc" network. You have to manually set IPv4 addresses for each machine, and if even one of them has gigabit that's auto-MDIX so you don't even need a crossover cable. But you do need ethernet ports on both.

And yep, a modem is definitely not ethernet. The ethernet cable won't even plug in.

There's also USB or Firewire networking, but those require special cables.
Thumbdrive is probably better. If you have the ability to crimp cables, you could build a crossover cable and set a temporary fixed IP address on each.
Wait: you wrote "from the old HP Pavilion modem...." No, can't run a cable from a modem port to an Ethernet port.

Just, not really, no. Transferring files over a network from machine to machine is perfectly normal.
