I made a crossover cable to connect two computers. The connections are correct, and I verified the cable both visually and with a tester. However, no matter what I tried, I could not make it to work. I then plugged a normal (non-twisted) cable, for which autosensing probably kicked in and solved the issue, and they communicate perfectly.
So now I am left open with a question. How is it possible that a crossover cable does not work? Is there some ethernet change I wasn't made aware of in the past 10 years that made crossover cables not working anymore?
