Reinstalled wireless drivers and problem is resolved.
FlexQoS FlexQoS 1.2.4 - Flexible QoS Enhancement Script for Adaptive QoS
- Thread starter dave14305
- Start date
Problem now resolved. Turns out it was modem related. I'm stuck (happily) in rural France where 4g is the only game in town for reasonable internet (around 60 Mbps/dl, bit less up) I typically use 2 modems - a Huawei usb modem (apparently it's not in 'true' modem config) and another, bridged, Huawei 4g router connected via the wan port. For reasons I wont elaborate, I was accessing the internet entirely via the usb modem during setup of the ac86u. For all intents and purposes the modems have worked well for a couple of years (except in load balance config - forget it) . I came across an old post by FreshJR where he noted that all upload traffic has to pass through eth0 to be traffic managed. That explained why under my QoS traffic Classification tab showed no upload activity whatsover, although offered a nice pie chart of download traffic. In my world 1 + 1 usually = 3, so I removed the usb modem entirely, hooked up the eth0/wan port to the other 4g modem and boom, everything worked - your FlexQoS script installed as expected, upload traffic now visible and an issue with VOIP call disconnects disappeared. While I realise this is an unusual combination of circumstances, there's now quite a community of users who are abandoning their landlines and moving entirely to 4g - perhaps this experience may be useful to a few. Many thanks for your help and for the script!

Is FlexQoS supposed to limit upload and/or download speed of the built in speed test?
With Flex enabled, download speed of clients is appropriately limited, but download speed in router speedtest is not. But both the upload speed of clients AND the router speedtest is limited with QoS active. I like the behavior of the former since this allows for full bandwidth testing on the fly without deactivating QoS.

Adaptive QoS will only be able to limit the upload side of a router-based speedtest, because the download limiting happens on the LAN interface (br0) of the router. The router speedtest doesn't go through the br0 interface, so it is not limited. The upload speedtest to the internet goes through the WAN interface (usually eth0 on most models), so it is limited per the QoS settings.
CAKE implements an ingress shaper on the WAN interface which would limit download speeds coming from the internet to the router on eth0.
@dave14305 having used both CAKE and Flex, what would you recommend to people to achieve lower latency based on your research? I know each environment is different and I keep switching back and forth between then every week haha. I like the customization Flex allows but just wondering what's your take on these options available. To QoS or not to QoS. Appreciated!!!
Either choice will work for most people. At higher bandwidths, CAKE suffers from the lack of HW acceleration. Adaptive QoS suffers from lack of transparency from Trend Micro. Adaptive QoS will always be updated by ASUS from time to time. CAKE is dependent on one person (often missing-in-action) to compile CAKE for new models/kernels, and Adamm for most script updates (we know that story). So I think FlexQoS has the best chance at longevity based on how the current landscape looks to me.
If you're at the point where you're worrying about latency between either option, your needs are probably highly specialized. Why do you keep switching? What doesn't work well when you decide to switch to the other side? You can't out-run a bad diet, and you can't out-qos a bad connection (or the speed of light).
Hopefully others will share their thoughts as well. I'm by no means the first or final word on this topic.

No questions or comments on FlexQOS itself. Just a lurker coming out of hiding to say thank you very much, @dave14305 for picking up where FreshJR left off! Was looking for an update there and found this updated project. It's been working like a charm, and I appreciate the bits you've added on!
Just sent a quick PayPal donation as a thank you. Keep up the good work <3

1. Does this mean fq_codel option still rely on asus? I thought they no longer support it since 386.x
2. As quoted from changelog, does that mean it's not as full fledge as the previous fq_codel in merlin 384.x/.19? What was the "secondary htb queue discipline" that it replaces?
Thank you.
1. ASUS never supported fq_codel. Merlin supported fq_codel. In 386, Trend Micro made it impossible for Merlin to use the same method to replace sfq with fq_codel so Merlin removed the support under Adaptive QoS. fq_codel is supported in Traditional QoS in 386.1 (in fact it's now the only qdisc supported in Traditional QoS). FlexQoS will always depend on Adaptive QoS though. That was my point. As long as Adaptive QoS is around, FlexQoS should be around.
2. It's simpler than the fq_codel implementation that was present in Merlin 384.
In stock Adaptive QoS, there is the top-level htb qdisc and class hierarchy that represents the 8 different application classes (Net Control, Learn-from-Home, etc.). Within each of those 8 classes is another htb qdisc and class hierarchy that represents all the devices on your network. Underneath each of those 2nd-level htb classes was a sfq qdisc (or fq_codel qdisc if using Merlin).
In 384, the traffic being shaped and scheduled in each fq_codel qdisc before was already very isolated (e.g. only Streaming traffic from Dave's iPad, or only Web Surfing traffic from Jerry's laptop). There wasn't a lot of contention within an individual fq_codel qdisc when structured that way, so there were limited flows and limited ability to provide fairness. Dave's iPad is only competing with other streaming traffic from itself (which isn't easy to do), for example, and a separate htb class and fq_codel qdisc is managing my iPad's downloads from the App Store.
My fq_codel implementation eliminates that per-device hierarchy so that ALL traffic within an application category (Streaming, Web Surfing, Downloads, etc.) is commingled into a single fq_codel qdisc for all devices, which I believe will lead to better fairness since the fq_codel qdisc will see all competing traffic within the category. So instead of 100s of fq_codel qdiscs in the old setup, you have 8 (well, 8 for upload and 8 for download).
Maybe this will explain what I mean by the old structure. I may have missed a small detail in my haste, but when you look at the diagram, you have to mentally duplicate the same device class hierarchy shown for 13: for all the other htb qdiscs 10: through 17:. The orange coloring shows what elements would be used to manage Web Surfing traffic from my TV.
In my fq_codel implementation, imagine that middle htb qdisc level being replaced by a single fq_codel qdisc under each application class. I don't have time to make that drawing right now, but it's much simpler looking.

1. Just to make sure I got it: so for 386.x merlin + flexqos fq_codel, the top level qdisc is still sfq, the 2nd is fq_codel, hence flexqos dependency on asus' adaptive qos.
2. Did you mean Merlin 384.x? There is no fq_codel in merlin 386.x, unless using flexqos' "simpler" fq_codel option
Thank you!

The top level qdisc is htb. The second level qdisc is now fq_codel.
I’m not sure what you’re questioning. There is fq_codel in Merlin 386, but only for Traditional QoS. Or with FlexQoS.

Sorry, yes I meant/implied adaptive qos.
Also is the reason for not having HFSC only HTB because asus' still on the old 2.6 kernel/sdk?
I think you need a math degree to understand how to configure hfsc. It’s available in the Merlin build according to modprobe -l.
FlexQoS has to respect the basic structure of stock Adaptive QoS, in order for the basic categories to work. That means keeping htb.

UPDATE: never mind, this only happens when copy/paste, have to type in manually.
Bug: can't enter port range, for example 19302:19309. It keeps saying "Please enter a value between 1 to 65535" and won't let you click OK. Tried with FFox and Chrome

I've set my amazon echo's by ip address to use the streaming category and I'm fine with ALL their traffic using that.....but the app rules are overriding this...when I play pandora on it for example the traffic is in web surfing. Is there a way to change it or do I just have to live with it (in which case I don't really need this rule).....additionally I have set security cams to "gaming" but I expect they are also using web surfing for the stream to cloud.

Are you also using IPv6? iptables custom rules that have IPv4 addresses aren’t applied to IPv6 traffic. Otherwise, post the output of

I'm not using ipv6. Cams are in the 192.168.3.2x range and echos/streaming is in the 192.18.3.3x range. Also is there a way to rename the bands even if just for display purposes? I'm not a gamer and would rather have VOIP as the highest level. I know it doesn't matter from a performance perspective. Here is the data as requested:
