@NickWan thanks for the note on the changed location for the config file; I’ve checked the firmware folder and there is a copy in there as well as the copy in the boot folder - how it got there I’m not sure, as I didn’t copy it there😄 (but the two are the same). I ended up using a 10m ethernet cable around the room (definitely sub-optimal) as the Pi and switch are not close to each other and that works, but my curiosity has now been aroused as to why it’s not working on wi-fi; next stop - logs.
