Ghost QOS or SQM, stuck at SLOW

Installing and Using OpenWrt Network and Wireless Configuration
#1

I have a weird problem today. It seems pretty likely that it's just some dumb config problem, but I am looking for ideas as I continue to poke at this.

I just set up a new router (Linksys WRT3200ACM, LEDE Reboot 17.01.4 r3560-79f57e422d). I have Frontier FiOS 50/15 service. Measured speed with dslreports/speedtest comes pretty close to that but with lousy bufferbloat.

Time to install SQM, except that I temporarily forgot that it was SQM so I installed plain old QOS instead. Oops, uninstall that and install SQM. Speed test now shows no better than 10/6! What? I've tried a variety of different configs, including the recommended cake/piec-of-cake, flipping my up/down speed estimates, etc. Finally, I uninstalled SQM and deleted the SQM (and QOS) config files from /etc/config.

Speed is still no better than 10/6 (and often measures worse).

Here is my hunch: when I installed QOS, it also installed a bunch of kernel modules and other things. Foolish me did not capture that info. When I uninstalled QOS, it only uninstalled qos-scripts and the Luci module. I think something must be left behind that is hindering me.

I know I can probably resolve this by reflashing, but ... lazy ... if there is an easier fix, like removing just the right kernel modules or removing a kink from my WAN cable, or....

Ideas?

Well, please post the output of:

tc -d qdisc
tc -s qdisc

to see whether there is a residual shaper left:

Also of relevance:
cat /etc/config/sqm

You might also review the SQM section of the LEDE User Guide...

tc -s qdisc (my WAN is eth1)

okay there is no shaper there, so I would say what you see is not caused by leftovers from either qos-scripts or sqm-scripts. Any output you can get from your modem/ONT?

#8

I have FiOS, and this router is directly connected to the network port on the ONT.

#9

Mmmh, could run mtr/winmtr against say 8.8.8.8 and post the results? Also could you post the results of a dslreports speedtest here please? See https://forum.openwrt.org/t/sqm-qos-recommended-settings-for-the-dslreports-speedtest-bufferbloat-testing/2803 for details about configuring that speedtest and how to post the results...

#10

I don't see any thresh entries for ingress or egress.

Have you configured SQM?

As requested above, run cat /etc/config/sqm and post the results.

#11

Sorry for the misunderstanding. As I mentioned above, I uninstalled SQM and deleted the config file.

#12

#13

#14

So, you have QOS installed?

Have you configured it in LuCI, or using the QOS scripts?

#15

No, I have neither QOS nor SQM installed. I had installed them both (separately), but I removed them both, and I deleted their config files.

#16

I did find this in /etc/config/ucitrack:

config qos
option init 'qos'

No idea if that means/does anything.

#17

Then it's no wonder you are getting F's for bufferbloat.

#18

Well, yeah, I'm not wondering about that at all. The first order of business is getting my speed back up to something close to the 50/15 I saw before this adventure started today.

Now, here's a weird thing. I've been running these tests all day from a laptop on my 5 GHz wifi. I know that's not a precise way to measure, but it should be good enough to see if I'm in the ballpark. After all, the original 50/15 measurement was on the same link.

I ran the dslreports test from my phone (cellular turned off) connected to the same 5 GHz wifi. It reports anywhere from 60-80 mbps download speeds. So, I ran a cable from the laptop to the router and tested again.

Come on, now. I'd be amazed if my 50/15 link were over-provisioned for 315 mbps!

#19

Run the following and post your results...

cat /etc/config/network

cat /etc/config/wireless

Note: Make sure to obscure the "option key" value(s) in the wireless config results before posting.

#20

When I test my sqm settings I never do it over Wi-Fi because it is just to unreliable. Always test sqm settings over Ethernet. After you get it set rite over Ethernet then do more testing with your WI-FI. Just to add to your troubles the Wi-Fi on the WRT3200acm is buggy anyway.
