I've just realized that I've got my wiring standards mixed up. All my jacks are punched down as "A," while all the plugs and patch cables and the patch panel in the closet are "B."
Everything works perfectly. I've made this mistake in my house, my mom's house, her boyfriend's house, and two other houses now (I got bad info from an installer friend.)
However, everything works, everywhere, with every computer that's been plugged in to them.
Are routers and network cards smart enough to figure this out? The difference in standards is that Tx and Rx (both + and -) have switched places -- right?
