Beginners Question on Ethernet with Mesa

Hi I possibly got off on the wrong foot.
I have no need at all to run the CNC and internet at the same time. Just CNC (Mesa) is fine. But I need to get back to that.

There is only one Ethernet port on my pc. I got mesa running on it, and what I think happened is that i plugged in the internet cable to see if it would work also.

I certainly don't need the two at the same time (meas and internet). In fact there is no physical way of doing that.

I have no need for internet to this PC, in fact I regret plugging it in as it seems to be what 'threw' my connection to Mesa settings.

At this juncture im looking for a way that will work Mesa only.
Looking for a well beaten track if possible.
Happy to re-install everything if it saves a lot of explaining! I presume a fresh install of 2.8 , and keep the internet ethernet cable far away from the port will work?

I would just re-setup the Ethernet port with the network manager for
the Mesa static IP address

There is no need to re-install anything

You can verify the connections with the command
ip a

With network manager its possible to have internet and a real time port
coexist (which is what most people tend to do)

I find having two connection quite handy. One goes to the Mesa card and the other is used for updates from the internet. I also connect from one of my other machines that I do my CAD/CAM work on to post GCode files to LinuxCNC The PC that I run LinuxCNC has two Ethernet ports on it so it was a little easier to setup.

As long as you have a spare USB port you can add another Ethernet port for internet.

Having a 2nd Ethernet or wifi connection may not be needed for the internet, but it is very handy, for moving machining/g-code files from your CAD/CAM work station to your CNC machine.
