Asus RT-AC86U - Abysmal wireless settings @default

Hello,

First time poster. Did some research here and on google and wasn't sure where to start with making some changes to improve my poor wireless speeds.

f/w: 3.0.0.4.384_45717

I have the Asus connected to a port on my Verizon Fios Quantum Router (1 gig up/down). When physically connected to router I see same gig speeds that I do when directly connected to verizon router, but the wireless speeds are terrible.

I attached (5) pics a Lenovo X220 laptop connected wirelessly...
