I have the Asus RT-N56U router. How do I find out if the router supports POE? A Google search for "asus rt-n56u power over ethernet" did not produce any meaningful results:

Also do all routers support POE?

The specifications do not list PoE so this device does not support PoE. Most routers will not support PoE.

I would guess more switches support PoE than routers

You can add a PoE injector to most networks that will allow you to connect a device that requires PoE to a switch or router without PoE. One example is the HP 1-port Power Injector (J9407B)

PoE is fairly rare in consumer-level products and not even a given on more expensive stuff, so I would always expect it to be called out explicitly. If you don't see it, it doesn't have it. – Shinrai Jan 16 '12 at 20:30
I was coming back to say 'Oh, and you can add a PoE injector' but I see Dave beat me to the punch. – Shinrai Jan 16 '12 at 20:40
