ok, I have automatic wireless back. Following a comment on Linux.com[1], I changed both the wired and wireless networks to roaming mode and then rebooted. Voila! I can now see all the wireless networks in my vicinity. Before rebooting I tried simply logging off and back on again but that didn't change anything. I suspect that rebooting was the key, that I didn't need to change the wired network to roaming also, but I'm not about to test it now as I don't want to break it again.
