Today I tried to hook up a Rocket M2 as a super powerful (miles) Wi-Fi

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?

Most devices do not need cross over cables anymore, but there may still
be the odd one floating around out there.

Aren't crossover cables "yellow"? Why use one unless required?
