I only had one problem with it, and that was that it isn't enough to enable it in the BIOS, but I needed to flip a switch on Windows and set up a systemd service on Linux (I dual boot).
I always wondered: why make it so difficult to turn on? Is it a security issue? I mean, an off-by-default OS setting and an off-by-default BIOS setting? How dangerous is this thing??
It draws more power because the NIC can't power off completely. So Microsoft and every hardware vendor are incentiviced to turn it off to look good. (And probably
to please regulations)
That it is defaulted off I feel is motivated, but to make it so hard to turn it on is pretty pathetic.
The fury Microsoft generated by turning it off in a Windows update still fuels me. I had a remote PC that I need to access remotely during holiday season. And Microsoft turns off my ability to power it on, with me left trying to figure out why I can't access the machine anymore.
Yep, pretty sure. m is for multicast.
