Celerron N2807 or J1900

I have a (older) BXBT-1900 and it runs Linux/LinuxCNC fine
I did install via a standard modern Linux distribution and then
installing a real time kernel and LinuxCNC

Did you try to disable UEFI in BIOS ?

Ok. Update: I take it all back the setting to change was CSM in the bios and disable secure boot

Thanks to all that helped.

Great you got it sorted. I don't need to take photos of my BIOS settings now

N2807 for me

Internal Wifi / BT Card needs to be removed physically or blacklisted and use usb wifi instead

Terminal:
lsmod
modinfo -F depends xxxxxx ( try to figure out what is using what)
sudo modprobe -r xxxxxx (temporary remove module)
rtl8723be was the name of my chip wifi/bluetooth

open file
/etc/modprobe.d/blacklist.conf
add --- "" blacklist rtl8723be ""
save

update-initramfs -u
reboot

I have the Brix J1900 and having latency issues.
I would be interested in your BIOS settings.
