Just an update that I received my 2 routers. One of them had still the sticky plastic wraps around it, while the other didn't. In other words one of them was "new", and the other one slightly used. Both are working, though.

And the power supply is the 120V "wall wart". Maybe they repacked new power supplies with these units when they "refurbished" these?

One question though: The "TEST" led keeps blinking in the status panel all the time. I need to google it to see what does it mean.

EDIT: Just red from the manual that blinking "TEST" LED means the unit is working normally... Kind of strange choice, in my opinion?
