Thanks, this seems to indicate both ingress and egress shapers getting activated, unlike you earlier tc output.
Could you please post the current output of tc -s qdisc again?

quantum 1514Looking at the output myself very briefly I can now see that the upload limit of 45Mbps is displaying which it wasn't before.
Yes, but this now is piece_of_cake.qos, so the /etc/config/sqm higher up in the thread is not relevant anymore, could you post the current output of /etc/config/sqm please? Just to check whether everything comes up as expected...
Okay there is one small change. eth1 is now on the first line which wasn't before.
config queue 'eth1'
option qdisc_advanced '0'
option linklayer 'none'
option download '300000'
option upload '45000'
option debug_logging '0'
option verbosity '5'
option enabled '1'
option interface 'eth1.10'
option qdisc 'cake'
option script 'piece_of_cake.qos'Thanks, so now the debug output (SQM_VERBOSITY_MAX=10), the current state (tc -s qdisc), and the config file seem to be in sync.
Now could you confirm whether in that state the PS4 is already slow?
If not, please leave everything as is and wait for the slowdown, then, please report the output of:
tc -s qdisc
again. Thanks in advance.

PS4 is going slow again.

quantum 1514There is really nothing indicating that cake/sqm noticed any latency/bandwidth issue at all. But that only means that SQM is not conscious of there being an issue and is no proof of no issue 
Time to figure out more details... what ISP & what plan are you using and could you post a a dslreports speedtest from the PS4 (does that even have a browser?)
When the PS4 goes slow, does issueing the following on the command line get you back to speed?
/etc/init.d/sqm stop ; /etc/init.d/sqm start
Also anything interesting to see in either logread or dmesg that appears around the time when the PS4 slows down?
I think I've found the culprit. I went through some of the services under System > Startup under LuCI and disabled and stopped some of the non-important services, ran /etc/init.d/sqm stop ; /etc/init.d/sqm start and then tested the PS4's internet speedtest till it jumped back up from 40Mbps to 200Mbps.
The culprit is nft-qos. I have already officially reported this bug regarding when it is enabled but no devices are in the list, it still applies the limits anyway.
Did you ever try nft-qos? Especially for the PS4?

No devices were actually listed in nft-qos as you can see in the screenshot below. The global limits were enabled though to 50KBps which matches the limits I was getting on the PS4 of 5MBps (40Mbps).
This is still a problem. There is a 11GB update for the current Call of Duty video game and these large updates are a perfect way for me to test the download speeds coming into my PS4. I have replicated the problem three times back to back by simply unchecking/checking the Enable Enable this SQM instance checkbox.
I have issued the following command /etc/init.d/sqm stop ; /etc/init.d/sqm start

SQM: simplest.qos was started on eth0.6 successfullyIt seems the checkbox breaks sqm-qos because after running the command above my PS4's speeds are back to full.
For how long?
My PS4 speeds were hitting the mid 200Mbps range in the PS4's speed test. My router stays on overnight and this morning my PS4 is still achieving the same speeds.
You consider this to be full-speed, I assume?
So the issue arises, if and only if you disable/enable sqm from within the GUI? But manually doing essentially the same via /etc/init.d/sqm stop ; /etc/init.d/sqm start leaves you in a state where the PS4 stays fast? If you reboot the router, but never ever open the SQM page in the luci GUI, does the PS4 stay slow or fast?
On PS4?. The PS4 has a rough speedtest that's not 100% accurate but hitting the 250Mbps is a good guideline.
My router has been up for two days since I last posted and I haven't touched anything. Somehow SQM doesn't seem to be working now as my internet speeds are exceeding 300Mbps (the limit I set) and I should expect about 280Mbps download. Disabling the checkbox, clicking save & apply, then rechecking the checkbox, clicking save & apply and retesting a speedtest brings back to 280Mbps ~
The PS4 has full download speed, but SQM isn't doing anything as my wired PC still exceeds the 300Mbps limit.
This is really odd, last time you posted the output of tc -s qdisc immediately after/during after the slowdown, tc reported the shaper to be operational. I am running out of ideas here, but you could try instantiating SQM on eth1 without the vlan tag and see whether that gives more reliable results?
This is what is displayed on a SSH connection to the router after issuing the commands

SQM: simplest.qos was started on eth0.6 successfullyOkay I've done some more reading through Google trying to find why the PS4 downloads are slow and there are some stories on the internet saying they've noticed it too. That rules out SQM being the problem for slowing down my connection.
However, using VLAN interfaces (eth0.* or eth1.* etc) with SQM and powering off the router and back on doesn't stick. My guest network is eth0.6 and it's bridge interface is br-guest. The network speed limits I have set on the guest interface works on the bridged interface after the router has been completely turned off and back on, but not the VLAN. Rather carrying on and diagnosing the problem on here which I don't mind doing, would it be better if I open a bug ticket?
Mmmh, so sqm uses hotplug scripts to try to monitor interfaces when they come and go, maybe our script does not trigger for VLAN changes at all?
