I reviewed one of those a long time ago. I'm afraid all I can remember 
is that it had its fair share of issues. I did a lot of factory resets 
and had to set the config through tftp *or* the UI but not mix both. Did 
you try doing factory resets (page 9-11 in admin guide) and/or 
downgrading to an older firmware release?
