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?

Swimmer Posted August 12, 2006 CID Share Posted August 12, 2006 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. Quote Link to comment Share on other sites More sharing options...
php Posted August 13, 2006 CID Share Posted August 13, 2006 Also, that duplex detection isn't extremely accurate... Quote Link to comment Share on other sites More sharing options...
