By the way, I've re-flashed 386.5_2 just in case and nothing changed

I’m going to speculate it’s an unexpected side effect of https://github.com/RMerl/asuswrt-merlin.ng/commit/f7b03e615d52dc11f7f7270807aa3de7e12f05b5 where FA isn’t being disabled on a non-NHD router. Your WAN interface should become eth0 with proper QoS setup, and not vlan2 as it would be when full HW acceleration is enabled. You can either mention this issue in the 386.5 thread or we can ping @RMerlin here. This webui logic is very confusing in what it was trying to accomplish and the fix may have broken the desired behavior.

What I understand is this is way beyond me and I’m gonna leave the stage to “Parts of the Furniture”

If you disable and enable QoS and then reboot, is it still broken?

What is the current nvram output of:

nvram get ctf_fa_mode

Yes still broken and the output is 0.
Also upload is broken in classification page too. And HW acceleration is

I just setup my old AC68U and installed 386.5_2 and enabled QoS without any problems, so my speculation may be wrong, or not widespread to all non-HND models, if any.

On a factory reset, only CTF was enabled. I enabled QoS and all was setup correctly on eth0.
I disabled QoS, withdrew from Trend Micro privacy agreement, and rebooted. CTF+FA now enabled and WAN iface is vlan2.
I enabled QoS again and it was still setup correctly again on eth0.

curious and curious, @pattiri did you make sure you were not somehow accidently withdrawed from the Trend Micro privacy agreement?

Checked it and I didn’t withdraw. To test I’ve withdrawn and accept again but issue is still there.
My router bricked upgrading to 386_5.2 and I’ve installed dd-wrt and openwrt before Merlin to make it work again. Maybe they broke something?
anyway I will try to go back 386_5. If it’s still broken I will try to reset router and configure all manually. I don’t know when I get time for this but I’ll keep you posted. Thank you both

Just flashed 386.5 and issue is still there. Probably only I have this problem :/

I'll nuke the router and configure all manually when I have time. Thanks again

Thanks Dave, tweaked to A+ A A+ at 491/31

Where do you test BufferBloat these days? DSLReports is down, and most others that I am aware of are chaotic, anywhere from A+ to D on subsequent runs, nomatter what you do with the QOS settings.

In considering FlexQOS for my old AC68U as a replacement for CakeQOS on AC86 after finding out that the AC86U's firmware is permanently broken and Asus is not stepping up to fix it.

My question is: are there any profiles that aims to serve as a simple "set it and forget it" for FlexQOS like is the default (and primary purpose according to the description) for CakeQOS?

If so, what's considered the minimum required in order to achieve a ~80/20 efficiency, not requiring lots of tinkering and tweaking over setting up the normal Adaptive QOS priority list?

I'm asking because I did not succeed in finding a simple and simply available explanation about this on neither on the Github page/readme, this page or any other sticky, and I'm tired of reading walls of text with poor structure (straight to the advanced details without explaining the concepts/overview/relevance first) before I know if it even does what I'm seeking a solution for.

The vanilla installation cures many of the inherent problems with Adaptive QoS. Tinkering is optional, depending whether Adaptive QoS classifies your network’s unique traffic patterns to your satisfaction.

Do we know whether Asus has improved those aspects of Adaptive QOS since the main part of Flex was written, possibly leading to conflicting settings? Are there any benchmarks and such?

Short answers are no and no. FlexQoS is just a continuation of the original FreshJR_QOS script, which pre-dates FlexQoS by a couple years or more. Asus doesn’t seem to think they need fixing.

I have to say, I am a set it and forget it kind of guy. When I installed flexQoS, I have not had to look back once. I almost forgot it was installed, it just works that well. I played around with some of the unique custom features today. @dave14305 I don't know if I would like my internet without flexQoS.

Quick update, reset to factory settings and configured everything from zero and all fixed now

I have a second bridge interface set up for my guest network. Is it possible to config the QoS rules for both br0 and br1?

Is it possible to copy the tc configuration from br0 to br1?

Not really. Adaptive QoS doesn't account for br1 or br2 yet, so I don't think there's a good solution right now. You cannot really manage download bandwidth if you're duplicating the bandwidth across two different interfaces. If you have 100 Mbit download, do you allot 70 Mbit for br0 and 30 Mbit for br1? It gets very complicated, and unmanageable.

This would be a scenario where CAKE would work better since it works solely on the WAN interface for both upload and download.

hi Dave,
is there a way/command to find out if FlexQOS is running ?

I am afraid mine is not running or setup correctly as my buffer float is C.
I am on 250Mbps download and 25 Mbps upload on RT-AX88U.

thanks for your help in advance.

You can run flexqos check from the command line to verify the modifications are made. Syslog will then show if any iptables or tc changes were made.
