Seems that I do.  I installed it and never got around to sorting it out.  I 
think that maybe the tray icon I'm complaining about is from that.  OK - so 
removed the plasma object - the icon remains.  I'll try a reboot in a moment 
to see whether the network activates properly.  Funny, though, in the past 
I've always been able to see the cabled connection even if the wireless one 
wasn't available.

In desperation I installed every tool I could see to help troubleshoot this.  
wlassistant tells me "Failed to connect to wpa_supplicant - wpa_ctrl_open: No 
such file or directory  CONNECTION FAILED".  If things don't work after the 
reboot I'll see whether it's still getting that message.
