I feel a bit like an idiot right now. I got my 7i76E all wired up in an older IH6000 mill that was originally using parallel port and mach3. I did a Linux Mint install following these instructions (Post 3:)
Complete Linux Mint 18.1 LinuxCNC
.
On the board I have the W3 jumper in the up position for 10.10.10.10 IP address. I modified my /etc/network stuff according to the mesaUS notes mesaus.com/info/7i76e.txt . My ethernet is enp4s0 so I set it up using that instead of eth0 or eth1.
I cannot ping the board but I can ping my source (10.10.10.1).
Output of: ip a
When trying to start linuxCNC I get:
What am I doing wrong? This is driving me nuts.

Did you power cycle the 7I76E after changing W3?

Yeah. Multiple times. I have lights on the board and only have power to P3

The amber one behind P3 and RJ45. Once I try and ping it at 10.10.10.10 I get the first two green ones behind RJ45 and the third one blinks. I can't read the board writing because of where it is mounted in the control panel case.

OK if the four green LEDs count up when you ping the card, its receiving data
so maybe some kind of host setup or MAC issue
whats does ping 10.10.10.10" report?

Strange.
a couple things to try are:
1. A different cat 5 cable
2. Disable IPV6 on enp4s0

You say you followed the instructions on post 3. I think those are the instructions for an RTAI install. That won't work for a Mesa Ethernet card. You need a Preemt-RT install (post 1 or 2.)

Neither of these worked. I did:
sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1
