Vincent, thanks for the input. The Network Manager is showing on the
toolbar showing the overlapped monitors with a large red & white x in
the middle of it.Tried your suggestion but nothing going, still have
the same icons in the task bar. Clicking on the icon shows that the
wired link is greyed out & not available for editting. Going into the
system>network tools and checking eth0 reveals that it is not even
registering.

As for wicd I have never used it, but to install it now would require
downloading the tar files then a make and bake session. Which I am not
totally opposed to, but what happened inside Xubuntu that the
previously stable network connection should simply die off on the
upgrade?
