I’ll be clear, I did a factory reset on my MT3000, then I disabled hardware acceleration, installed SQM and then I tried exactly what you described, SQM is still not shaping upload speed after a reboot, I tried with eth0 and eth1 (wan is eth0 on MT3000)
Not sure why is not working for me, keep in mind that I’m testing over WiFi, via an Ethernet cable it works great when I choose eth1 after a reboot. op24 firmware.
What am I missing?
That's okay.
Maybe you should check to see if any other software is affecting your computer or phone
This is the test data after the restart

I plugged the router back today and tested and it's working, didn't change a single setting!!!! That's strange but after doing that it's working, so unplugging and plugging it back to the power after doing the steps resolved the issue for me @ywp
Hi @Steve68, were you able to get it working on the Flint 2? If yes, what configuration did you use?
This was the solution, test it and let me know
It's not shaping. Maybe you can see what I've done incorrectly? @Steve68 Thanks!
I'm using firmware: 4.6.2, release1, from gl-inet
I've installed: luci-app-sqm: git-21.188.55209-f161b40
I've edited the /etc/hotplug.d/iface/96-gleqos file as per instructions
I've set the interface to eth1
I've set both download and upload to 4000
Queue Discipline is set to cake
The startup script includes /etc/init.d/sqm restart
I've rebooted the router after making all these changes.
Update:
I've now disabled the netnat network acceleration.
Now it's shaping up 
A+
(Shit connection, but at least 0 bufferbloat.) Thanks @ywp & everyone in this thread.
What's your ISP speed? Just wondering why you have used a low value for upload and download
@j2zero, it's 50 Mbps down and 12 Mbps up. I was using 4000 kbps to validate if the speed would be limited to be sure the settings were applied. Strange thing though, 4000 kbps resulted in 2 Mbps... I expected 4 Mbps.
I was going to say, if you have it set at 4000 then you should be capped at 4mbits and by your results it would indicate it wasn't actually working.
I guess you have now set it to something like 30000 and 10000

You've guessed correctly.
I use the standard settings, didn't bother with codel and still get A+ results, I just need to get it to be persistent across reboots like you have done via the script. I am running the Brume 2 and it must have the same startup bug.
For now I just restart the SQM plugin via Luci after I reboot, which is rare as it's my main router.

Try raising your download speed to 40000 - get that as high as you can. You can have around +4 on the download and upload before you lose a rating.
The upload speed seems to be a main factor to dial in more to get the A+ not so much the download, from what I've found.

This is not necessary, just the step I said and disabling Network Acceleration should work, reboot to confirm. If you have 50Mbps download, I’d try with 45000 as value
(90% of your speed)
Or if your get less or more than 50 just measure it a couple of times and do the math and add the 90%, works good to me

Are you setting the eth0 or eth1?
I'm using eth1 @Renato
I too tried downloading and enabling the SQM service on Flint2 and noticed a noticeable improvement by testing with https://www.waveform.com/tools/bufferbloat going from a B to an A+
But enabling the service (and disabling the hardware acceleration) cuts the bandwidth speed to 1Gbps or less instead of the 2Gbps or more I usually have
Do you know why?
The SoC cannot handle that kind of speeds especially with offloading (network acceleration) disabled and SQM enabled.
Pity! I had noticed an improvement (and not a small one) in that test...
It can’t candle 2Gbps with SQM enabled but 1Gbps is still insane, most routers can’t even reach 500Mbps.
i have this exact issue also with cs2 and valorant
