i have one i think i'm going to sell ( i bought it at best buy so it's model is rt-ac66r, but its just a rt-ac66u renamed for best buy), decided i want a apple router. i don't need all the extras on this router. it's like new and i still have the box. i've only had it for two or three months now.
crap. nevermind, i see now you said n66u. my bad.......free bump.
