What can I tell you except to reiterate that you shouldn't be
using .../networking.

Read "man interfaces", set up /etc/network/interfaces to use DHCP and hwaddr
(Is this what Michael suggested?  I can't find all the posts in this

Then you should _not_ be doing anything else to that interface.  If you need
it to be able to bring itself up and down, use ifplugd.

And don't use the GUI.  It's fine for setting things up _once_, but it
shouldn't be necessary and it's obviously breaking things for you.
