[Andreas Schultz]

Wireless network was working fine with matic, but system can no longer connect to wlan after noble upgrade.

NetworkManager logs contains this:

Iwd logs does have this log entry:

Jan 02 15:44:19 zeus iwd[6299]: AP did not include group number in response!

However, that warning is not new and was present before the upgrade.

Update:

Building and installing iwd-2.12 from debian/sid fixed the problem for me (some Ubuntu fixes need to be applied to the debian package).

It seems that this could be a compatibility problem with the newer kernel and the older iwd.
