Patrick,

I run iwd on RPi, but I am using Arch Linux. I've never tried it with
RaspiOS. Works pretty well, though I am having a re-connect issue that we
are trying to debug.

My guess is that you compiled the kernel to remove this message in the log:

Aug 23 22:52:24 rune64 iwd[235]: No Diffie-Hellman support found, WPS will
not be available
Aug 23 22:52:24 rune64 iwd[235]: The following options are missing in the
kernel:
Aug 23 22:52:24 rune64 iwd[235]:         CONFIG_KEY_DH_OPERATIONS

This is harmless and I have no problems connecting with this notification.
I think it means I cannot use WPS which I do not.

Are you trying to connect using the iwctl commands?

iwctl station wlan0 scan
iwctl station wlan0 get-networks
iwctl station wlan0 connect 'Network_Name"

It should return with

Type the network passphrase for "Network_Name" psk.
Passphrase: ********

or are you using connman to manage iwd?
Do you have an /etc/iwd/main.conf? If so, what is in it?

I assume you have enabled and started iwd.

Keith
