Questions related how IntelliQoS works and my experience with it

[reshuffle812]

First time Keenetic user here.

I enabled Traffic Classification Engine, and I have a theoretical 100Mbps/20Mbps connection as download and upload, although I'd usually get 92Mbps/22Mbps, and after having a Keenetic that's around 87Mbps/22Mbps now. I'm not sure if that's caused by Keenetic router, or the cheap Ethernet switch which supports up to 100Mbps.

Anyways, I'm not exactly sure how should I use IntelliQoS. When I only enable Application Classification and Application Prioritization (which auto enable the other) options it does nothing helpful, Bufferbloat tests show the same. When I enable Smart Queue Management in the same page and set it to 85Mbps/20Mbps, bufferbloat tests gets better. Basically bufferbloat during download is up to 10ms, and for upload it's 0ms or 1ms at max. Even better than download, although I have more download to spare, but somehow bufferbloat during upload became better.

So is this the only way? I'm not sure if it makes any sense like this, my previous router was TP-Link, given by my ISP, and as you know ISP given (or rented) routers have an interface controlled by ISP, most features limited, but even there limiting QoS per device would give me the similar results.

I was expecting Keenetic's anti-bufferbloat solutions would work better because I have more control on that router, am I wrong thinking that? Or did I do something wrong in the setup?

Forgot to include main concern here, main concern is that limiting network speeds manually like that, I have seen some OpenWrt users talking before and I didn't heard they have to do this network limit.

Hi, @reshuffle812

What problem are you trying to solve with IntelliQoS?
I see that you check the configuration by running a bufferbloat test, but if you could elaborate on what you're trying to achieve with getting certain values there, maybe we can provide a better advice about how to configure the Keenetic.

I'm just experiencing the new router I bought. I was expecting IntelliQoS to work without limiting my overall network speed, but it seems not to. Bufferbloat test results are same if I don't touch SQM parameters. So what are the other options useful for? The priority options. I was trying to achieve better bufferbloat tests than my previous router, but without limiting network speeds of devices.

In order for IntelliQoS to properly prioritize traffic it needs to know the total amount of bandwidth available, that's why you see different results after manually specifying the download and upload speed.

You said before that without any IntelliQoS configuration you typically get bandwidth values around 92 Mbps (download) / 22Mbps (upload). How do you measure those values? I am asking, because you said that you see different bufferbloat results after entering lower values manually (85/20). Could it be that the lower numbers are closer to the actual bandwidth of your connection?
