ASUS RT AC68U slow download speeds

I have the Comcast Xfinity internet 600/20 plan and using ASUS RT AC68U with Merlin.
When I did a speed test behind the router, I am getting 200/20 speeds. But when I am connected directly to the modem, I will get close to 600/20.
I think the router is my problem and how do I fix it?

Are you using (or have used) any of the AiProtection options on the Asus router? Its a common issue some have experienced if one has enabled the AiProtection to see a speed drop. The general workaround is to disable or turn off AiProtection and then access the Privacy page under Administration and Withdraw from any listed options on that Privacy page.

I have app analysis off, QoS off, classification, web history off. Withdrew under privacy page under adminstration. Still nothing worked.

I disabled STP under LAN and seem to have gained the maximum speed of my provider. Do I need STP if I am using only 1 router?

No idea if Spanning-Tree Protocol needs to be enabled or not. It appears it's default setting is on/enabled. One may need to reboot their router after turning off AiProtection and Withdrawing from the Privacy.
