I had similar problems with my network using a cheap switch with some realtek nics. I had the nics running 100baseTX Full Duplex. Changing this to autosense made the problems gone. Reason (as some people of the german questions-list told me): Many cheap switches always send their autosensepakets, and have great problems if the nics connected to the switch do not response to the autosensepakets (cause they are configured to 10/100baseTX full/half duplex). Also realtek nics are far away from being good nics, they work without problems with the autosensemode and a cheap switch for me (and many other people I know). I would suggest the starter of this thread to use autosense with his nic (if not tested yet). > Kris Best regards Sebastian
