I do have a switch, but it isn't plugged in at >the moment (I took it out of the loop to help troubleshoot the network >problems, and instead ran long patch cables point-to-point [ie, from the >router to the PC with no intervening hub/switch or wiring that I'd >installed)] to eliminate variables. I'll put the setting back to 10bT >half-duplex, but it seems that the critical factor in getting the wired >network to work with the SWC7004AWBR was to disable "automatic" sensing >and/or to disable 100bT throughout. > 100baseT is unreliable at best on 'crossover' configurations (netcard to netcard)... it relies on the hub(or switch) to perform some retiming functions to clean up the signals. this is especially true on long runs. now, if your SMC thing has a built in hub/switch, well, then ignore this.
