Can not connect to Mesa 7176eu

I have spent many hours searching posts and looking for answers. i just can't figure this out. I followed tommylight post on how to configure a wired ethernet connection. When I click save it comes up with a message "a gateway is incompatible with never-default.
The computer is a Lenovo m910q,  Intel Core i5-7500T . I am a total newb at linuxcnc, but successfully completed 2 mach 3 machines in the past. please help this senior citizen. Thanks

Gateway, set it to 10.10.10.1 as in the how to, or just delete it as it is not used in this case when you set it for local network use, that you did not set, and that is OK if you do not use any other network but should be set nontheless.
Also, did you set the jumpers on Mesa board for 10.10.10.10? Default is 192.168.1.121, see Mesa manual.

Thanks for the reply. The jumpers on board are; W3 up, W15 up, W13 down, W14 up.

IP 11 at the end, not 1
Gateway 1 at the end.

I have made the changes that you suggested. Still the same message appears when I hover over the save button. That button never gets highlighted.

 

I would leave the gateway and DNS server entries empty
as they are meaningless here.
