I think it is useful to change the title from
"Linuxcnc & the Rpasberry Pi"
to that 
"Linuxcnc & the Raspberry Pi"

Dude please don't change the subject, it makes things hard. I check this thread regularly.

Ok the description is a little vague.

I don't think a clean install will "fix it". I don't think an update would have anything affect as the kernel,kernel modules and firmwares should not be touched during an update. In all honesty unless you are wanting to update Linuxcnc, there shouldn't be a need to do an update, most updates are just minor fixes that really don't affect the way Linuxcnc operates. The biggest "security threat" to cnc machine is someone getting physical access, and it would be the machine it self I would be the most worried about, blood gets everywhere, it's hard to clean and the injured party may want to blame you. I only will have wifi on when transferring files to the cnc machine, other than that I disconnect wifi.

I think you maybe experiencing an issue similar to what is discussed in this thread. Which it would is not Linuxcnc related, it's the ethernet port going to sleep/shutting down, tho it should be tx\rx ing packets more or less continuously. Yes I know it's a direct connection from the Pi to the Mesa card and the thread mentions switches a few times.

It seems to be somewhat random to which boards are affected but I haven't noticed this on my RPi400.

Tho it might be an idea to check the power supply for the Pi & the mesa card. But if ti was the mesa card "dropping out" you would get notifications.

I installed LinuxCNC onto a RPi 400 with a touchscreen and GMOCCAPY. It works very well, but something has changed on the system and it is now unstable. LinuxCNC, is locking up after periods of inactivity. Running a Mesa 7i96 board. Wonder if doing another clean install will fix it. Might have had a bad update along the way. Will let you know what I discover....

Hi everyone,I've started developing an I/O board using the Raspberry Pi Pico. The prototype will feature 8x 24V outputs and 16x 24V inputs, communicating over Ethernet UDP with a real-time HAL driver. If everything works well, I plan to develop additional boards with step generation, analog outputs, and encoder inputs.At the moment, things are still evolving—I'm currently having the first batch of 5 PCBs manufactured and have already ordered the necessary components. Communication between the Pico and the real-time HAL is already working. :)I'll keep you updated as the project progresses!

Wifi setup is by running

Be sure to edit to choose option 5 "Edit wpa_supplicant" with your country code, ssid & password.

To setup network for a mesa fpga Ethernet card, choose option 6 "Edit interface" and modify eth0 to match post above if you have jumpered the board for "FIXED FROM EEPROM"
If you have jumpered for "FIXED 192.168.1.121" replace 10.10.10.100 with 192.168.1.100.

If your home wifi network is on the 192.168.1 network, use the 10.10.10 network for your Mesa card, refer to you card's manual for jumpers to change.

After config reboot
To check the network type in a terminal
Taken from 7i92 Manual

A final note, there is no network notification applet for the desktop, so you will not get any notifications when the network connects, disconnects or reconnects.

I am new to linuxcnc and I cannot get my Raspberry pi running linuxcnc to connect to wifi or to my mesa 7I92TM board. I tried ip a but the mesa board is not showing have looked everywhere online and read multiple forums but can't seem to find a proper solution to my problem. Please help.
