The switch itself. It sounds like the switch may be having a conflict between any two given NICs. And as for plugging the modem directly into computer #2, did you use a cross-over cable or just a straight cat5?
Because if you are connecting anything (two computers, one computer to a modem etc. )without going through a switch or a router, you must use cross-o.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
