PPPoE performance on GT-AX11000

[MRizkBV]

Switched to a new ISP yesterday that uses PPPoE. I got the PPPoE and VLAN tagging details from the technician and tried to use my GT-AX11000 but it maxes out at ~500 Mbps up/down when I pay for 1 Gbps. Using their own router gets the full speed (~940 Mbps).

Is there anything I can do to get the full speed on GT-AX11000 and ditch their router?

I updated to latest ASUS Merlin and checked the Flow Cache and Runner status, both were enabled. I also do not have QoS or AI Protection enabled.
