Now my problem is that I can't manage to get the WiFi working and I sorely need it for development. I'm pretty sure I ran some older release that had it working (with network-manager) out of the box but network-manager does not seem to be installed by default in this version.
What I tried is apt-get install network-manager and after that I reboot and launch the terminal based GUI with 'nmtui'. In here (in previous versions) I used to see a list of SSIDs to connect to but now the list is empty. I'm guessing that there might be an issue with some driver or similar and that no WiFi chip is recognized but I don't have the knowledge to check. Has anyone else got their WiFi up and running on the latest Rpi5 image?

I can at least confirm a pi 5 that is able to find WiFi networks. In my case nmtui did work I chose something I remember was called ‘activate network’ and it would show a bunch (and prompt for password).
With kind regards,

Actually I prefer MATE and have made images for myself with the MATE desktop without any of the XFCE4 hangover, but it is simple enough to install MATE on the std linuxcnc image, whether amd64 or arm64.
With regards to wifi & networking in general.
sudo apt install network-manager-gnome
I like the gnome applet as I like to turn wifi off when running Linuxcnc.
If a touch screen enumerates as HID it will just work. As the images we build use the RPi-Linux sources it may be a kernel module that isn't included in our build to support non HID touchscreens.
On screen keyboard, just a package we don't include.
Reasons for not using RPIOS, the fact that it uses wayland as a default and X compatibility layer is very slow, so slow that there is a significant difference when running latency tests between wayland (as stock) and changing to X.
Branding is also an issue, something I really want to deal with. Debian isn't so restrictive, hence the reason the PC images changed from Ubuntu to Debian.
There is also a thread some where on the forum regarding Linuxcnc on RPIOS. The topic author slips my mind at this moment.

Hopefully this will end up as a one stop for most issues and advice.

That is really weird. I did exactly that but my list appear empty. Fresh install 2.9.4 and thensudo apt install network-manager
Did you use the 2.9.4 from downloads page, I think thats rodw's, right? Version of Rpi5? (I have the 4GB)
I also tried sudo apt install network-manager-gnomeAnd when I pop down the little menu there is a grayed out text "device not managed" and under that is only VPN connections. Any idea what might be off on my system?

I found a solution for my missing WiFi connections.
Second method mentioned in the top reply. (first method didn't work for me)
askubuntu.com/questions/71159/network-ma...s-device-not-managed
***
.....
Then open the file:
sudo nano /etc/network/interfaces
Delete everything in that file and copy and paste the following:
auto lo
iface lo inet loopback
Save, stop and start network manager:
sudo service network-manager restart
***
I had to reboot my whole system but after that WiFi works like expected.
