DSL-AC68U, need QoS configuration advice

[emr8989]

Friends, I have Asus DSL-AC68U device. I want to fix the bufferbloat values on this device.
Merlin is installed on the device. QoS is not working as I want. "Cake" is recommended by everyone in SQM structures but there is no such option in my panel.
Is there any other way to install a smart queuing system on this device?

Cake needs newer kernel, your available options are Adaptive QoS and Traditional QoS.

Thank you for your response. So should I stick with these options or buy a new product?

Use what you have, test available options, see how it goes with what you normally do on Internet. If you test bufferbloat with online test sites - don't. The test saturates your connection and creates bufferbloat conditions, something you normally don't do with normal use.
