Have you tried connecting two computers with just a patch cable? With the auto-sensing Ethernet ports, it works as if the cable were a crossover cable.

- bpye 5y agoI believe this is only true for gigabit - though almost any device today should be?
- compressedgas 5y agoI'll admit that I don't know if it would have worked then. And it has only been recently that I have got two computers which both have gigabit ports. I don't remember ever using a crossover cable as I always had a switch. I do remember having to manually assign IP addresses in that configuration as it didn't have a DHCP server to assign them.
- hackmiester 5y agoNot all auto-MDIX ports are gigabit, but almost all gigabit ports have auto-MDIX.
- jcrawfordor 5y agoAuto-MDIX was starting to become the norm on nicer hardware when GbE started gaining adoption, and the MDI layer of GbE effectively obsoletes the concept of MDIX by specifying that pairs must always be probed. This was sort of required due to GbE requiring four pairs while Fast Ethernet required two, it is sort of expected that a GbE interface will encounter improper cables and it needs to detect that to degrade to Fast Ethernet. So for GbE it's all but guaranteed, for Fast Ethernet it depends on how much money the device vendor was willing to spend on the interface, basically. Later laptops should be pretty reliable. Or course none of this has anything to do with Windows, it all happens at a hardware level which can sometimes make investigating problems a bit painful.
