What kind of modem?  My Alcatel ADSL modem states in its manual
that it provides a 10BaseT half-duplex interface and that's the
way I run it.  I've never seen these problems, but I had a long
wait for Telstra to put the ADSL on the correct line and I've
only had my ADSL service running for a few days so far.
