Today I tried to hook up a Rocket M2 as a super powerful (miles) Wi-Fi
extension for my home router, when the POE light went out whenever I
plugged in the power cable. Huh?

Turns out it's a crossover cable, mixed up with the bunch of my other spare
Ethernet cables.

Do we even need crossover cables anymore?
Or did they go the way of 8-track players?

I found myself with a box of them and I just cut the "crossed" plug
off and crimped a straight one back on. Be sure you swap that with one
on a live 1gb connection and run it for a while, wiggle it around and
shake it to be sure the connection is good. Nothing is worse that
stocking a bad cable.
