CakeQOS GT-AX11000 with 1.5gbit symmetrical fibre internet and QoS

[dusan78]

Hello,

I am searching for some answers regarding using cake QoS on a Fibre 1.5gbit symmetrical connection which I just got. I am using a AX11000 router. Without it I am getting 1gbit download and 1.4gbit upload using the speedtest on the merlin router GUI. Running the test on multiple devices I can pretty much get 1.3-1.5gbit bandwidth combined. However my issue was testing the waveform bufferbloat adds latency under load and I get B or worse grade at the moment.

Enabling cake QoS reduces my speeds all the way down to 500 upload and download and whats worse is that if I run tests on multiple devices, I am getting 500mbit max combined so on two devices the speed would split to 250mbit each and so on. However, the bufferbloat is now much better at A or A+.

This mirrors someone elses experience on this forum but, I also read someone else getting 1gbit with it enabled. So is this something I am not setting correctly or is the limit of cake really at 500mbit and with faster connections should be disabled or other QoS service used. Any advice would be greatly appreciated as to how to get best latency as well as bandwidth possible for my setup.

Thank you!

IMO, Cake is not necessary for 1.5 Gbps symmetrical connection. Consumer routers cannot handle the processing overhead.

Thank you, is there any other QoS that would work to reduce the latency I am getting under load.

Same as you, have 1.5gbps with gt-ax6000. For my Bell ISP, Have used QoS and disabled it as i have noticed that your weakest link is websites, torrents, steam(max. 400mbps for me) games, etc.

Besides, QoS will only be triggered when you hit max 1.5 ~ 1.3gbps(depending how you setup.) and even for multiple heavy users for me it was never activated. As always, YMMV.

Don't waste your time with this website.

(That waveform test is debated by people as to its accuracy...)
Symmetrical 1.5Gbps is a pretty healthy connection to be maxxing out in a typical home environment, and your router is a rather capable machine to be managing it. I would suggest that you might consider looking into network segmentation (vLANs and Subnetting) rather than QoS.; let your ISP do the speed control - if you manage your traffic onto their highway, chances are they won't slow you down

To give an update as I have solved my problem with latency. I played around with adapter settings where I disabled "throughput booster" and I also disabled "autotunninglevel" as per someone else's advice from another thread. These two completely eliminated any latency but, I did have to trade in some maximum single connection speed. If I was copying a large amount of data over the network I would turn this back on but for everyday use it's perfect.
