My THEORY is that the driver chips on either end were wearing out and no longer able to send or receive as well as they once did. When you run the correct pairs, the wires are twisted together. This is important for a variety of electrical reasons, too lengthy to cover here, but a quick google search will give you a lot of info if you care. If you use an ethernet cable, you are using a pair of wires that is not twisted together, removing the electrical advantage of twisted-pair cable. > Obviously, the connector pins were still correctly set. > If it stopped to work, then it must come from the electric signals and > should explained through cable impedance or things like that. > Yes, exactly. -- Carlos Alvarez TelEvolve 602-889-3003
