The Pi5 comes with dual band WiFi so external access is probably possible.
I'm using an older PC with 7i92H. Playing on the lab bench with a Pi4 and
7i82H, LCD touch screen etc.
The problems I've run into are more along the lines of user interface with
respect to the smaller touch screen. In the long run likely a bad purchase.
There are 42 other projects in front of this one at the moment but I thought
I'd ask.

The pi has a micro hdmi for video, and any old 1920x1040 monitor just
works. So video is not a problem here. I have all machine power
controlled by a pair of 60 amp 600 volt SSR's controlled by linuxcnc's
F2 key, so the pi is not equipt with a power switch. Uptimes are power
failure to power failure, so pi & monitor are around 22 watts when
linuxcnc is not running. Rod Webster can supply sd card images for
bookworm. Latency is not as good, but plenty adequate to run my lathe
well. Currently running with 3 phase closed loop steppers on 45 volt
power supplies, no PID's. They do EXACTLY as the TP tells them to or can
shut linuxcnc down with the e-stop in a millisecond. Tested well, has
never occurred while actually running a job. Whats not to love?

Hi all,
Will the Pi5 be any better for LinuxCNC than the Pi4 with a MESA
Ethernet
Controller or is the Pi4 already more than what LinuxCNC requires?

I am running a late 1940's Sheldon 11x54 first with an rpi3b, but its
tongue was dragging on the floor, and I've not seen any evidence of that
since switching to an rpi4b not long after it came out.
I did put many of the "manual functions" in a separate 200 hz thread
while it was still running of the 3b, and have not taken any of it out
since swapping in the rpi4. My .hal file is available, just ask, for a
7i90HD & a triplet of 7i42TA's to anyone who asks. It uses a Spinx1 to
talk to the vfd. This leaves the ethernet free to tend to the usual
network stuff. Like updating the os or even browsing you-tube.
