I have RBK40 and RBK50 Mesh router, both has WAN-to-LAN low performance problem under AP mode.
For special and external services, I use x68 OpenWRT as my main router and it is with a embedded NAS system. In the meantime, I set RBK50 as AP mode,
1) RBR50's wan port connect my main router's lan port
2) my desktop connect RBR50's lan port.
As time goes on, I found that When data transfer between my desktop and NAS, connect speed never exceed 70MB/s, but when unplug cable from RBR‘s wan port and plug in RBR's lan port, speed back to normal (about 110MB/s), so I google it, it seems a common problem in Netgear product, link below is the throughtput test (WAN to LAN, LAN to LAN):

I perform throughput test in my network, RBK50 and RBK40 do show the same problem. Both FIRMWARE has been updated to the newest version-V2.5.2.4
I don't want to add any other equipments to get a normal network experience, I already pay the money. PLEASE comfirm the issue and FIXS it in your Orbi products as soon as possible.
