Ethernet connection to Mesa 7i76e disconnecting on its own after one minute

  I ran pnconf wizard and made a configuration for my CNC plasma table. I am able to home and jog my machine for about a minute until I get this error. 
It seems like the ethernet connection is disconnecting on its own somehow. Any ideas on how I could get the ethernet to stay connected so I can use my machine.

Is this possibly Plasma/EMI related?

That is, do you still get communication loss when the Plasma source is off?

I don’t think it is Plasma/EMI related. My plasma cutter was not connected or turned on.

What does:

sudo chrt 99 ping -i .001 -q -c 60000 [card_ip_address]

report? (it will run 1 minute then print statistics)

[card_ip_address] is either 10.10.10.10 or 192.168.1.121 depending on 7I76e jumpering

 

Sounds like host or 7I76E issues

Whats does

ip a

report?
