Bandwidth throttling problem (big problem)

Hi all again,
I'm trying to throttle my bandwidth but it doesn't seem 
work. I read all mails about that in this mailing list, 
and I made everything you suggested - making throttle.fw 
executable, loading all needed kernel modules... but it 
doesn't work at all. I would like to know if anyone of you 
can make the magic, or suggest me how can I get help. 
Thank you very much
Monica
