ASUS AC86u - wireless AP mode issue on latest firmware

Hi all,

I've recently purchased an Asus ac68u to work with my Sky fibre router to act as AP to boost the poor wifi performance of the standard sky router (Ie. Turning WiFi off on current sky router and using Asus for all wireless functionality).

I've seen online that I need to turn Asus router into AP mode via administration page on the router UI, however I don't have the option to do this - infact I have no option to change "mode" whatsoever

Just wondering if I'm missing something -...
