I have installed Ubuntu 22.04 LTS; and Debian, using iwd, systemd-networkd, systemd-resolved.
I have tried to follow the instructions here and here, but to no avail.
The most I can do is view available networks, either in the gnome graphical interface or iwctl. Trying to connect to the networks will fail.
I've created a file for my own future reference reference here, in an attempt to explain my thinking and what I have tried. In short, I believe the problem to be that bcrmfmac cannot find the file brcm/brcmfmac43602-pcie.clm_blob, and regardless of having the .txt and .bin file.
Big thanks in advance.
