7i76e what am I doing wrong

I am trying to setup my computer and Mesa 7i76e card. As my luck usually goes it's not going as planned. I did the network-manager install as per instructions, However when I click on "edit connections' I don't get the "wired connection X" option. So I click the plus key and follow the rest of instructions on the sticky page " Mesa ethernet setup for 7i92, 7i96, 7i76E and other ethernet Mesa boards. was created by tommylight " . After I do that though the computer still doesn't see the board . I notice that were the ethernet cable plugs into the computer it shows 1 occasionally blinking yellow led and one red-ish orange solid led. The connection on the Mesa card has a solid yellow and a solid green. I have verified that the ethernet cable is good.
The Computer is a Dell optiplex 7010 and running Debian Buster . What have I missed or what am I messing up ?

What does

ip a

report?

using terminal it reports this

Right so you did not manage to get a static IP address setup on the host
Did you select "manual" in the networks managers "IPV4 Settings" tab ==>
"Method" drop down, and enter a static IP address for the host?

When you are done you should get something like

: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
link/ether ec:b1:d7:6c:a2:da brd ff:ff:ff:ff:ff:ff
inet 10.10.10.100/8 brd 10.255.255.255 scope global eno1
valid_lft forever preferred_lft forever

For the Ethernet section report of ip a

this is with W3 jumper on the 7i76e in the up position correct?

Yes, that is copied from my test setup where the FPGA card IP address is 10.10.10.10

confirmed W3 is in the up position. but it's still giving me problems. I think I will just call it a night before I take a sledge hammer to it all
LOL. Thanks for the help thus far PCW.

I am starting to wonder if my 7i76e card is the culprit. I reloaded Linux Debian Buster and tried again.
tried the instruction from the above posts. Same result. I put W3 back in the down position pulled up Terminal and typed
ping 192.168.1.121 , however it reports " connect: Network is unreachable ". I am kind of lost at this point. does what I just did prove there's an issue with my 7i76e board?

"connect: Network is unreachable" means you cannot access that IP
address from your host, that is, your host PC Ethernet port is not setup properly.

If you are having trouble with the network manager, an alternate way to setup
your host address is by editing the interfaces file. (/etc/network/interfaces)

This is what is in my interfaces file:

Note that the "hardware-irq-coalesce-rx-usecs 0" line only
applies if your PC uses a Intel Ethernet chip.

Is that being done in terminal?
