It sounds as though the two were being asked to give conflicting orders.  I 
should remove it from one before testing the other.  It may simply not have 
been working because system setting told it not to.

The screenshots arrived, but I am afraid that I am not used to sorting 
networks out by looking at icons and I'm not really sure what I am looking 
at.

Did you run 
$ ip addr
while the wireless was working?

If it is working, then do:
$ ping 8.8.8.8

followed by

$ ping www.google.com

and send us the results.  You may have to use ^C to stop the ping command, 
depending on how your system is set up.

DNS shouldn't affect connection, only finding sites.

I still have no picture of your network at all.

How (apart from the icon) do you know whether it is working or not?
