              Asus RT-AC66U vs Asus RT-AC66U B1 - User Opinions

                A: The B1 indicates that this is the newer version that Asus released in late 2016. The newer version upgrades the processor to handle more traffic and places more shielding around the USB ports to reduce the interference caused by the lack of it in the original version. Helpful?
