Rockpro64 with 7i76e was created by acondit
I have a Rockpro64 4gb and a mesa 7i76e. I currently have linux-stable-rt-4.19.31-rt18 plus linuxcnc installed.

The rockpro64 has a gigabit ethernet port. I assume (dangerous thing I know) that I should use the gigabit port to hook up the 7i76e. Does that sound correct?

The next problem is, if I want to run headless (ssh) should I buy the wifi module for the rockpro64 or would it work to buy a USB3 to ethernet adapter to hook to my network?

the Gigabit ETH is not a problem so you can move on

USB to WiFi is another option. Those are pretty cheap:

the wifi makes itr very flex to position the mashine like Plasmas to a save place and no real connect to the main shop needed

I just tried to start linuxcnc. I set jumper w3 up instead of down and the ini file is set for ip address 10.10.10.10. However, I got an error network unreachable.

Any suggestions appreciated.

Can you ping the card?

I tend to test without LinuxCNC when setting up.
halrun
loadrt hostmot2
loadrt hm2_eth {experimental parameters}

With less in the system it is easier to see what isn't working.

Ping reports network unreachable.
When I tried the
halrun
loadrt hostmot2
loadrt hm2_eth board_ip="10.10.10.10" CONFIG="num_encoders=1 num_stepgens=5 sserial_port_0=20xxxxxx"

It reports unknown parameter 'CONFIG="num_encoders=1 num_stepgens=5 sserial_port_0=20xxxxxx"'
wait_pid failed /usr/bin/rtapi_app/hm2_eth
rtapi_app exited without becoming ready.

If ping doesn't work, it means your network is not setup to access 10.10.10.10
That's not really related to LinuxCNC but a basic network setup issue

Did you read the hm2_eth manual page? it has a bit about network setup
Also if your computer has a network setup GUI, set the host Ethernet port
to a fixed (static) IPV4 address of say 10.10.10.20

To find the ethernet adapter name
ip link show
or
ip a

sudo gedit /etc/network/interfaces

auto enp0s25 << change to match your interface name
iface enp0s25 inet static
address 192.168.1.100 << if you use the mesa card 192.168.1.121 ip
netmask 255.255.255.0
broadcast 192.168.1.255
