Try using something other than pump, namely dhclient.  Or dhcpcd.  If
you remember, at MCL we used to have some problems where some people
could get IPs fine if they used pump, but not dhcpcd.  Others had
the opposite problem.  I've run into this at home, too.

Not anymore.

Presumably it was working under Windows?  Or did you even try it?
Did he give you a CD?  You may need to install it.  Or call tech
support.  I vaguely remember having to go through some sort of
web-based set-up thing.  But I thought that wasn't necessary any more
either.

If Matt B. says this is the problem, don't listen...  ;-)

One day all of a sudden I noticed the same thing.  AT&T/Comcast seems
to have done something to reverse the sense of the modem lights.  They
appear to blink OFF when there is traffic.  YMMV.

I thought I remembered that this isn't necessary any longer, but I may
be mistaken.

Know anything about security, Paul?  =8^)
