NEVER ever _set_ a 100Mbit port/card fixed to Full or half duplex 
or data rate!
There is only a protocol for "auto negoation".
But there is no protocol for "manual set up".
Every vendor makes his own assumption, sometimes the wrong.

And: Turn every properity protocol "extensions" off!
(3com and cisco are so arogant and tries to force ther
standards into the market regardless of the problems their customers have.)

It simply does not work, yes.
Serveral Card vendors ignores -wisely- the presets the user did...
See ethernet driver writer Becker postings to this problem.


BTW:
"Hubs" can only do half duplex.

Sometimes two cards using a crossed cable can't find each
other.


>So check it an go on half duplex if you are not shure.

Check, using netstat -i, if the cables are garbage.
There should not be any erors or very very few.


Under "ftp.heise.de" there is a tool "NetIO" which
allows to check Network thruput (gives at least "raw" hint).
