I have 2 PCs running Windows XP connected to a router to share a broadband connection. There are 3 green lEDs that light up when the network cables are connected: 10/100, Link/ACT & FDX/COL.
Recently the FDX/COL LED has stopped showing when my PC is connected to it. I have tryed different LAN ports to see if the problem was the LED had broke but it is whatever one my computer is connected to. The LED still lights when the other computer connects to it.
There doesn't seem to be a problem with the internet but i would like to know what the FDX/COL means and what will have stopped working (if anything)
does windows say the network card is working ok? have you tried swapping a cable from one of the computers that works? I have have had many problems from cables, even new ones. Im sure most of them arent tested but just thrown into the wrapping and shipped to shops.
