Actualy I just finished work and would start playing with it again right now! I just "make-shifted" assembled it on a case with a decent PS and some hot swap bays.
I tryied also with RaspiOS, with their imaging tool. I already tryied what you suggested, with following behaviour:
Booting from a USB Stick (RaspiOS) "works", very slow. So I am not sure if the problem persisted cause it was nearly impossible to use it, but wi-fi was there.
Booting from the same image on a Hard disk, but then, it does not recognize ANY wi-fi card, so, I am not really sure where is the problem. Hard wired in on the network, and update it, without any suceess: still, NO wi-fi card/interface present.
With your OS it kinda worked, I guess, that was how I installed OMV, over Wi-Fi, but it was pretty forward and "fast", at least for the dowload part. but then I got the problems. It is on right now (Interceptor OS), but weithout any wifi connection, although my router shows it to me, I can not connect to it.
I just connected a mous/keyboard/monitor, and your settings are again empty, I choose wi-fi again from settings, automatic, and now it work, but loose IP after a few minutes.
P.S. Anyway to make it boot from HD? After several instalations, on many different HDs, it still needs a USB with your image on to boot to SDA0 or SDB1 (or something).???
I will be here for a while, so, if I should trty anything, no problem, just write it.
