Well, first of all. welcome!
To install the noX iso, use the cli-installer, but there is a bug, the /etc/fstab seems not to be generated, please check this.
Maybe you have to do it manually, this shouldn't be a problem.
Or use the xorg iso, so xou have the most important software like the xserver and usefully firmware.
Also we have iwd and network manager configured to be used with your WiFi.
in noX use iwctl or the cli tool from the network manager package. There is a manual page for it.
The manual is worth to be consulted.
Why there is no gnome iso?
We do not have one in our team who use gnome and is willing to support it.
Most of our team is using kde or xfce,
sorry, we are a very small team.
So if some one is willing to configure and setting up gnome for our iso , he/she is welcome, don't be shy.
