Mesa 7I92TM goes offline shortly after starting LinuxCNC

You need to select "Manual" rather than Automatic on the IPV4 page

FIXED!!

Thank you so much for your help,

 

Just wanted to take a moment to thank everyone who helped, I'm now up and running with my first Mesa card (big step from Parallel )

The machine is faster, feels smoother and just as accurate. 

Also whoever (I think it was probably TommyLight) suggested Dell Optiplex 7050's I was stunned and pleased to find out you can get them on Amazon for $150 and the latest Debian/LinuxCNC loaded without a hitch.  I see all my machines getting upgraded to Mesa and Dell soon.
 

Have you had any time to give a Dell OptiPlex 7050 a rub yet?
It would nice to get some feedback and recomendations regarding eventual tweaking :0)
Kind regards/Stefan
