Sorry I am out of ideas, except that some (including myself) who have
had problems with Network Manager have had better results with wicd.
You could install that and give it a go.  I think it is only a few
hundred kB download and is very easy to setup.

One other final thought, is Available to All Users checked for the
connection?  If so, and if not greyed out, then try clearing it.
