Not necessarily. The RT-AC66U_B1 uses the RT-AC68U hardware, but in a different form factor similar to the RT-AC66U.Yeah. Just to add MORE weirdness.... the AC86U has 2 fewer LEDs than the AC68U. So, the motherboard for the AC86U would not even work in the AC68U case. So, if there IS an RT-AC68U_Extreme that is really an RT-AC86U, it would have to look identical to an RT-AC86U as well (only changing the model number).
