That is weird. I’ve flashed the card two time and have tried the card on two boards. In both cases, when I go into Dietpi-Config, Network Options:Adapters, it shows the adapter is not found. When I try to enable it, it says no HW found, and asks if I want to remove wpa-supplicant. I know the card works because I can boot radxa’s debian XFCE image and get Wifi.
I will try again later and gather the information. This one is weird!
could be the script is not detecting wifi hw correctly. Probably manual configuration might be needed. 
em… it’s really strange…
how about manually insert your wifi driver again?
rmmod brcmfmac && modprobe brcmfmac
and see if this could bring wifi back?
Here is what happens…
root@DietPi:~# rmmod brcmfmac && modprobe brcmfmac
rmmod: ERROR: Module brcmfmac is not currently loaded
how about only execute
modprobe brcmfmac
It executed without any error, but it didn’t do anything (that I can see). The wifi card still is not found.
oh I’ve overlooked the dmesg log you’ve uploaded.
after looking into the log, it seems the problem is the initialization of your wifi chip was failed due to gpio error?

did you have an image with a working wifi? which version is that?
radxa-zero3_debian_bullseye_xfce_b4.img
From the Radxa download site.
I have two of the boards up and running as Octoprint Servers.
It was the same image I used to create this dietpi image.
so strange that the wifi was missing as all the components shall be in place and it’s working fine here.
Anyways, I’ve just heard from radxa that they just released their new image b6.
Maybe I would run the dietpi install script again and give you another image for testing.
what’s your 3W wifi module’s model, is it AP6212 or AICxxxx, there are two hw version of zero 3 now, you can use new version b6 to do a test, which supports both AICxxx and AP6212
Not sure, the boards are pretty new, I just got them a week or so ago. I’ve had really bad luck with the Radxa images. Most that I try refuse to boot at all. The B4 version has been the most stable for me. None of their CLI images boot for me.
Maybe you could try this image freshly built.
b6 dietpi test
The apt sources is not yet cleaned and the firmware is not yet fixed.
But you could see if the wifi was detected by dietpi-config.
Hi, It will not boot completely, I get this message.
dietpi.txt (3.2 KB)
I guess this is related to
Source list to be fixed, cleaned, corrected.
Probably… I have two boards up with the B3 XFCE image and they are doing what I want them to do (be Octoprint Servers). This is my test board, so no harm or foul. 
If you are in the mood, you can also correct the source list yourself on the current system.
To get an overview
for i in /etc/apt/sources.list{,.d/*.list}; do echo "$i:"; cat "$i"; done
Yes, it is not yet fixed so boot error is expected. But did you get your wifi detected in dietpi-config this time?
No wifi, same as before. I did boot with the B6 XFCE image and I do have wifi.
em… really strange… I’ve managed to get the new image with working wifi on my board.
could you let me have the output of sudo dmesg | grep firmware to see if it’s the firmware problem?
My recent trial seems the wifi problem also exist in my board, so I’ve made a new image with B6 which should be able to support both wifi chips on the two verisons of radxa 3W zero.
I would be glad if you could help test the image when you are able.
