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.

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.
