Somehow NM is convinced that it should try an Ethernet connection first. You need a way to disabuse it of that notion. What does your /etc/network/interfaces file look like? Is your Ethernet device present there? If so, try commenting it out and restarting NM. Otherwise, as Brad Rogers <b...@fineby.me.uk> mentioned, https://developer.gnome.org/NetworkManager/stable/NetworkManager.conf.html may have some tips. -- Does anybody read signatures any more? https://charlescurley.com https://charlescurley.com/blog/
