Mesa 7i96s / Network no longer working

That looks OK.
Did you use the Network Manager to set up the network?
If yes, you need to check the "use this connection for local ..... " not sure what exactly it says as i am on the phone.
That is for wired network only, IPV4 settings.
You also have a wireless network and if that connects before the Lan, it will send all trafic through wifi, if the above is not set for wired network.

I think i used networkmanger, but iam also able to set the ip with ifconfig 
The Ip Stack will notice 10.10.10.10 is on the same subnet  as 10.10.10.2/24, so it will allways send packets for 10.10.10.0/24 to that interface. (unless statics routes exist)  It also worked for like >1 year in this config and it still works for the lathe mesa with the same ip as the "broken" one. I also tried some other Laptop, with no luck

Sounds like something has gone wrong with the Ethernet section of the 7I96S card.
It should be repaired/replaced under warranty, Contact Mesa or your dealer for instructions
 

Ok, i fear that too. But i will hook it to this Jtag debugger thingy at work, just for curiosity

Will post if i got some insights ..-

Ok, this is getting weird ... Yesterday i mounted the mesa card from the lathe into the mill, all worked fine... made parts for like 3+ hours .. Today i power up the mill again and the second mesa card network is also no longer working I dont understand, there was zero change to the electronics, since decenmber last year or sometime around.. (added 3d-probe)
The only power coming to the mesa card is 5v from a step down converter (24v->5v) which goes into the vc+/gnd and +5 to the input common.. all outputs go to a relay board. China spindle to pwm 0-10v . Xyz-axis Stepper drivers are on a seperate 48v psu, A-axis Stepper is on the 24v psu

This setup was working for ~1 year... Is there any chance some voltage spike (iam no electronics guy ) could kill only the ethernet ?

It does sound like something on the mill is causing major EMI of perhaps ESD

Ethernet is transformer isolated and the 7I96S has ESD protection on the
7I96S side of the transformer so should be fairly well protected from surges.

Large ESD (static) discharges can cause damage however. Protection from
static damage is improved if the 7I96S frame ground pin is connected to earth
ground.

Hi.

Did You have any luck fixing the card. I have the same exact problem.
