I am facing similar problems with Masa27 - Asus AC1200G+ running on AP mode behind Singtel AC Plus has problems with wifi, but wired is fine.
This is my setup:
ONR -----> Singtel AC Plus
Singtel AC Plus -----> Singtel TV
Singtel AC Plus -----> Linksys EA8100 (AP mode) -----> Singtel AirTies Mesh
Singtel AC Plus -----> Singtel Aztech (AP mode)
Singtel AC Plus -----> Asus AC1200G+ (AP mode)
When Asus is on AP mode, wired Internet works fine. However I am unable to connect to wifi. Even when connected, the speed is like <5mbps. Problem is resolved when Asus AP is plugged directly behind ONR. However ONR is at one corner of the house that is inaccessible, so I cannot plug my Asus AP or Singtel TV to the ONR. Funny thing is setting Asus to router mode (double NAT) works fine initially, but after some troubleshooting suddenly router mode also does not work. How come my Linksys and Singtel Aztech AP can work but Asus cannot?
