Fibre internet 150/150 and Asus AC86U router issues

[wireless]

Hi all, I'm just wondering if anyone has experience using the Asus AC86U with internet 150? I'm having a challenge with getting my AC86U to work properly on the internet 150.

When I connect the AC86U straight to the T3200M without bridging, I get under 1Mbps up and down which is horribly slow. I tried the same with my Netgear R7000 and the same slow speed.

When I connect the R7000 directly to the ONT, the speed is amazingly fast at about 175 up and down. When I connect the AC86U directly to the ONT, I get about 9 up and down only.

When I use a wireless extender to connect to the R7000 or the T3200M and then connected by Ethernet port to my AC86U, I get 150 up and down.

Is there a Ethernet conflict with the AC86U to the ONT?

Any assistance, suggestions and idea are welcome! Thanks in advance!
