LinuxCNC not connecting to 7i96S on 2.9.1 was created by rowow
FIXED*** When installing the linux cnc OS I had the ethernet port connected to the internet. When doing a new install with it disconnected it worked. Some errors come up (see page 5 of thread), but try to get through them and it works.
Ive installed linuxcnc before successfully with my mesa card, but recently changed to a new computer and after a fresh install of 2.9.1 and following the exact same steps I did before to get my mesa controller running it now puts out the following when launching

while reading through dozens of forum posts I used a command which got the mesa board information and pins through the terminal and it listed all its information successfully. I however forgot the command I used to be able to do again and post the results.

Usually the "resource unavailable" issue is something wrong
with the host setup or link status. Its often temporary after
making some change in the network settings.
To read the card info:
mesaflash --device 7i96s --addr 10.10.10.10 --readhmid > pins.txt
(and post pins.txt here)
Possibly unrelated but your ping times are quite long.
If you have an Intel Ethernet chip, you should disable
IRQ coalescing as described in the hm2_eth manual page:
man hm2_eth
You can try disabling this with a terminal command but
the setting will revert to the defaults after reboot so its
best to disable the IRQ coalescing in the interfaces file
as described in the hm2_eth manual page.
To disable IRQ coalescing on the command line:
sudo ethtool -C [Your_Ethernet_Device_Name] rx-usecs 0
Note that you may need to install ethtool on Debian
with the host setup or link status. Its often temporary after
making some change in the network settings.

reading the card info does not do anything.
and for disabling IRQ the ethernet_device_name would be enp1s0 or the custom name I gave it

Will create a file "pins.txt" that you can post here
Also the results of the command
ip a
May be helpful

All looks OK, you might try disabling IRQ coalescing and see if that helps
sudo ethtool -C enp1s0 rx-usecs 0

Did the ping times improve?
What is your servo thread period?

What is LinuxCNC's servo thread period?
If the ping times did not improve, there is something preventing good
Ethernet latency. What is the host machine hardware?
