It may "just work" if you power down and restart the DSL modem...
it caches the local ethernet address sometimes and won't work with
another..

(I notice that the windows and Linux are the same (different) machine
from that used
by BSD.. The DSL modem, once initialised to that machine may refuse to
work correctly with the 
other machine (I've seen this many times)

on the other hand it DOES look as if you are getting part way through
the 
initialisation.
I don;t understand why the provider comes back with seven service names,
unless he is offering you seven possibilities. He however is NOT
providing an AC-name!

very wierd
