Thanks, well it sounds like ive got some good news, that auto senceing feature you were mentioning, turns out when I checked it out that my router has all 4 ports as autosenceing. I have never heard of this before. Then I must be able to plug the crossover into the rotuer and not wory about any ics or routeing os. Now as for the nics I know one i purchased last year, another was about 2 or 3 years old as it was given to me from a friend who got it from his isp who didnt want it back. The third nic I have no idea where I got it from or when. And a 4th one I got free from some online group called freecycle, shich i believe might be a combo nic and wireless, except its missing the antena.

Im gona try the setup with crossover from rotuter to computer C since ive learned of this special ability my router has
