Problem with Dual WAN

Hi all,

I have a problem with Dual WAN on my ASUS RT-AC88U.

I have Merlin 384.19 installed. Recently I just add another internet connection into my home cause I'm interested in using the Dual WAN feature on RT-AC88U.

My previous connection has 45Mbps speed. The new connection has 75Mbps speed.

I tried to setup Dual WAN Load Balancing, with both WAN on PPPoE. But no matter port I tried, port WAN always has trouble connecting to PPPoE.

The error message is Timeout waiting for PADO...
