Resulting in limited speed of 288 Mbps, rather than supposedly 866 Mbps on 80 Mhz (.11ac).
I have tried disabling DCA, setting custom channel to 80 Mhz, but my devices can only get 20 Mhz. Happens on various firmware from oldest to latest.
What's strange is on EWC dashboard it shows that my laptop is negotiated on 80 Mhz, but on the laptop itself it's still 20 Mhz (please refer to attachment).
Is this a bug or something i misconfigured?
