Alright, I'm gonna ask: This is a joke cable right?

Every time I see something I'm absolutely sure is a joke cable, somebody links me to a piece of real hardware that actually needs that monstrosity of a cable.

But this time, I am 99% sure... Nothing actually could possibly have any use for this cable....right?

I would be more sure if one end wasn't a network cable end. Networking people have some deeply weird cables...

This simply converts an ethernet LAN port to wireless WiFI IEEE 802.11AC (110v AC in US and 220v AC in other regions). Pretty standard stuff. At least that is what the IT support guy in the alley behind the pizza place told me when I bought it.

Is that what PoE means?

Ethern't.

Ah yes, the Etherkiller.
