Yes, I usually hear about iptables rules not working with newer routers. tc filters (AppDB rules) hadn’t been a problem so far. If plain Adaptive QoS works for you, just stick with that, or CAKE.
FlexQoS FlexQoS issues with 388.4 HND5.04 models

Is there any known incompatibility between 3004.388.4 and FlexQoS? I was installing the beta versions off 388.4 and at beta 3 the router became very unstable with reboots every half an hour maybe. Went back to 388.2_2 and everything returned back to normal. Then 388.4 came out, tried with dirty upgrade and again the unstable issue appeared. This is when I decided to do a WPS factory reset and reconfigure from scratch 388.4. All addons I am using are FlexQoS and YazDHCP. Again, I had multiple reboots of the rooter every few minutes. Things returned back to normal when I just uninstalled FlexQoS. That’s why I am asking. My next move will be to install it again and monitor the situation.

did you reformatted the USB/ssd drive ? if not try doing that.

I did not. I have attached a 2.5 SSD 120GB with a SATA to USB enclosure and haven't experienced any issues so far. If the issues arise after I install again FlexQoS, I will reformat the drive.

I agree. I did had to fiddle around a bit too. but after FD command and reinstalling in same order as 1,2,3 div, sky, flex it's sort of sorted. still have some latency on upload but I do get A score which is good enough. up until beta 3 it was A+ same settings. so it could be some flaws in new firmware too.

I concur, there seems to be some issues that were introduced based on the latest changes from ASUS to the QoS. I have noticed some nuances when adding maximum rules to FlexQoS using the iptables options. I maxed out with 25 rules. Upon extreme network bombardment (kids playing on their gaming platforms, while I was streaming movies), the router decided to do a random reboot. I detected the router reboot once all my devices lost wireless signal. Once I logged into the router, I observed the harddrive mounting and all scripts firing off as if the router just came out of a reboot. Since I went back to default rules on FlexQoS, the issue went away. Cannot get above an A on bufferbloat tests (no A+, with or without FlexQoS installed bufferbloat never goes above an A). This leads me to suspect, there may be something bugged out in the QoS not necessarily directly introduced from FlexQoS. However, I believe those using FlexQoS are more susceptible to discovering the bug. If I understood more of the dynamics of the QoS internals, I would try to debug further, but I am out of my league in that arena.

that's exactly what I listed above in my post. I narrowed all of my issues down to flexqos APPDB.
This was the response "If plain Adaptive QoS works for you, just stick with that, or CAKE."
I like flexqos but if they aren't going to support it, I guess I'm throwing in the towel.
Having said that the June release of Asus 3.0.0.6 addresses a number of CVEs and Merlin isn't going to look into 3006 for some time so right now I'm back to the latest stock firmware.

A bit out of scope, but to my understanding latest Merlin's firmware 388.4 uses Asus code base GPL 388_23588. ASUS did patch a number of CVEs in June's update. For my router (RT-AX86U Pro) that was 3.0.0.4_388.23565. Hence, Merlin's 23588 seems to already includes what Asus stock 23565 has. That's my understanding.

thanks. I went back to 388.4 with skynet. I tried flexqos again on a lark. nope. problems with it again. uninstalled and stable running just skynet

Yes definitely seems to be a problem with the newer AX models. I do remember having a lot of disconnect issues (with A. QOS enabled) while trying out the AXE16000 and AX11000 Pro version a few months ago when it was 1st supported by asus-wrt merlin. I never tried it with stock firmware. I ended up returning them not figuring out what the issues was at the time and I ended going back to my old AX11000. Hopefully this ssue can be resolved.

I wouldn't put too much stock in Bufferbloat. There are too many factors involved and I've run tests back to back before where a C magically turns to an A with no router config change and vice versa. We simply can't control the whole path nor control their internet feeds.
Having said that, router reboots are horrifying.

Understood. I try to refrain from using qos at all unless I have saturation. There's always added latency when the router has to tag every flow. I'm certainly not defending Asus if they have botched something.

In my network, I have no choice but to use QoS. First factor is my download, upload connections are symmetric. Upload can be horrible without it. Second factor is the amount of clients in the pecking order and saturation to the network.

Ya, different strokes. I have about 30 devices that can take or leave QoS. Gaming, Dropbox, Netflix, Prime, Disney, VOIP, Work from home, torrenting, MS Teams. Even with everything full bore QoS adds little benefit for me. Teams, gaming and Voip phones all work fine. Everything else can use it's cache. I was big on QoS back in the days of early hi-speed (5 meg) but a lot of people don't realize that the ISPs tag traffic along the path which takes care of most of it. (and our markings don't persist through the ISP anyway as it's local outbound only )

Thanks Dave! FlexQoS is one of my favourites Add Ons. I'll try it.
I can see the discussion goes on what Asus might have done with their code, but for me the problems started on 388.4 beta 3. Was any codebase change between 388.4 beta 2 to 388.4 beta 3?
Also, I have another RT-AX86U Pro that I am remotely managing which is still in 388.4 beta 2 with no reboot problems. When I saw the problems with my main one in beta 3, I just skipped the upgrade.

Just installed FlexQoS and got my first reboot in two days and half days. Here are some logs
I also got another one, probably when tried to save configuration of fq_codel >> Asus , but no flexqos entries on the logs on the second reboot. I will be monitoring the situation and report back.
