Hi Jens, IWD actually has its own mailing list: iwd@xxxxxxxxxxxx as well as an IRC channel #IWD on freenode. You may want to ask on either of those. Also, before doing that, it would be more helpful to run IWD with the debug flag "-d": ExecStart=/usr/lib/iwd/iwd -d Thanks, James On Mon, 2018-11-19 at 15:35 +0100, Jens Heyens wrote: > Hello, > > Hopefully, I am not wrong here, but after looking through the kernel > wiki, I thought this would be the right place to ask. > > I am having issues with iwd not trying to connect to any access point > (essentially, not scanning at all) if I use the hardware switch for > the > wireless devices of my notebook.
