Why can't connect to public wifi? Why only 1 wifi net profile

Thanks, Nils, that pointed me in the right direction.

I had knetworkmanager installed, but every time I displayed it, I got a "no active devices" message.  After searching around the web for awhile, I finally found that this was an error experienced by some others.  It seems to have to do with manually configuring the network.  After that, knetworkmanager refuses to work.

I deleted most of the entries in /etc/network/interfaces and rebooted.  Now I was able to configure knetworkmanager with my home info.  I'll have to see if it works correctly next time I visit my computer club, or other open access point.
