  Ok ,  notice the  ALARM    , duplex mode. The switch  (EZXS16W) Linksys , is meant to sense full or half , why does this test find this problem and what  if anything can I do ? I've seen this before on tests . Any one?

my guess is that it is complaining about the fact that you are running a modem, most of which can only do half duplex, into a switch that is running a full duplex..  I wouldnt worry about it to much.. I have never really messed with duplexing but as long as your speeds are ok dont loose sleep over this... I would keep the switch at full duplex so you can send/receive to clients on the network at the same time.
