I need an answer

Ok I tried but I seems the controller needs to be hooked to the web see attached screen shot.
I will lug the controller inside soon.

Ok new info I have setup QTPlasmaC on the same controller and just ran a simple G-code about 9 times with using the MDI to go back to X0Y0 before each start. Not a single error. Total time the controller was working was about 30 minutes.
this could not have happened with Axis. Now the question is why the difference??
I plans to use the table for Plasma and other functions (routing, drag knife, scribing and maybe laser engraving). This is why the 2 GUIs are needed, I can do this with the other table I have built Non-LinuxCNC but the G-code commands that LinuxCNC uses I need separate setups.

or reverting to 4.x real time kernel (if possible)

This is the issue. Current USFF hardware generaly lacks driver support in the 4.x kernels

Yes, when setting up a PC, live is much easier if you bring the PC inside and connect it to a wired network connection. Don't be tempted to use wifi. It might work if you have to but wifi is  a lot slower than wired.

When I do bring it in I use a wired connection, its easier to connect.

 Ok I have made progress with changing the driver, but have hit a wall. I an not very Linuxcnc knowledgeable but I am learning. Following the link that RodW posted above, it seems I an not entering the correct step. I get into grub-customizer and try to load the new NIC driver as shown and I get an error. I may be using the incorrect terms but I'm a newbie ): ): please indicate what I am doing wrong.

It shows the 5.10.0 still in there 

The network driver is an Intel e1000e so its not a realtek card.
Have you experienced an error finishing read when using your mesa card?
If not, you probably won't need to update the kernel.

If you do, grub-customizer is really just a convenience. You can update-grub without it. I am a bit rusty on how to do it so someone else would be better equipped to help

In the meantime, when the grub menu is displayed at boot time, press the down arrow and select the new 6.1 kernel for now. You may need to open a menu to see alternatives by hitting enter on the second entry.
