I have the same issues. It worked properly, but about two week ago it stopped suddenly without any changes in the Netgear D64000 router. The DLS Link is up but the WAN is not connected.
Though, there was some scheduled maintenance in our area (Brisbane City) on that time.
So, I had to put the old TP-Link back, but it's very unrealiable in the WLAN (Wi-fi) i.e. frozen occasionally, cannot login to the TP-Link and I have always power off nad on again.
Also, I do not have access to the above mentioned Setting up 3rd party devices to work with TPG internet
It says Access denied.
I am sending a PM to you with my username and phone.
