Joulinar · 2023-03-08T06:01:35Z

Did you reboot the system in meantime?

as-shura · 2023-03-08T14:08:33Z

Yes tried many time and the error still persists.

Mar 08 03:03:22 DietPi dhcpd[15472]: No subnet declaration for wlan0 (no IPv4 addresses).

That seems to be the issue. Can you share following

ip a
cat /etc/hostapd/hostapd.conf
cat /etc/dhcp/dhcpd.conf
cat /etc/network/interfaces

MichaIng · 2023-03-08T20:58:19Z

It seems it cannot find the configured interface. Please check:

cat /etc/default/isc-dhcp-server

which must match the intended WiFi interface shown in ip a output.

Isn't this supposed to be dhcp instead of static ?

iface wlan0 inet static

as-shura · 2023-03-09T00:04:32Z

This is really interesting !!!!!

I just flashed another microSD card and ran the same OS with another odroid-c2 board with the USB Wifi stick and it worked. I am wondering what is wrong with my original installation.

Ok I found it the difference was at these lines

pre-up iw dev wlan0 set power_save off
post-down iw dev "WIFI_DEV_IFACE set power_save on

They were both missing in the original odroid-c2 I setup and that's why it was not working. Now it is working.

Joulinar · 2023-03-09T08:09:53Z

pre-up iw dev wlan0 set power_save off
post-down iw dev "WIFI_DEV_IFACE set power_save on

But these lines are not added by our tools. At least I'm not aware of.

as-shura · 2023-03-10T09:59:32Z

But these lines are not added by our tools. At least I'm not aware of.

It is actually in fact because I never touch those line personally. The dietpi-software made it and initialized the settings.
