I just installed openwrt on my wrt3200acm using a PureFusion build, and I have set up cake sqm using the guidelines from this page. I just upgraded to this router, as my previous router did not have the cake qdisc available, and I am getting ping spikes still. I am connected via ethernet, and have connection speed of 70/18. What could I be doing wrong?
Please post the following information here
output of the following commands run on a ssh terminal to your router (please copy and past the text from the terminal window and paste it as preformatted text b clicking the "</>" icon in the forum tool bar)
ifstatus wan
cat /etc/config/sqm
tc -s qdisc
- run a speedtest, e.g. the waveform bufferbloat test and post the link to the results here
tc -s qdisc
# again
also how did you notice the ping spikes (how did you measure them)?
What kind of link, DSL, cable/DOCSIS, or true fiber? And what ISP are you customer of?

As for what im using to check for ping spikes, https://ping.canbeuseful.com/en#ping
My ping is completely unstable when looking at this, it spikes up to 100ms randomly, but pretty frequently.
Im with BT, and I believe im using VDSL, as we don't have fiber, but are living in a relatively new development (2 years old)
Try the Waveform bufferbloat/speed test mentioned above.
Waveform results look good.
See this disclaimer on the ping test website...
Reliability of this tool?
Although this tool is reliable, the ping time measurement is indicative and not as accurate as the ping command. This is due to the fact that the tool uses the HTTP protocol(S).
I reset all my settings to default, swapped over to vanilla openwrt, and put my settings in again, just to make sure it wasnt my config. I currently am the only user connected to the network, I added my phone, and started streaming netflix, and my ping became instantly unstable. The waveform test works on my pc, and I get good results, but anytime an actual device outside of my pc uses the internet, my ping starts to become unstable. https://i.gyazo.com/dae141b1db8d015f5db8dcfe40466bb2.mp4 (the graph was flat before i started streaming netflix on my phone)
This is the fast.com result from my pc
This is how my ping spikes when i run the fast.com test on my phone
For some reason, other devices on my network cause my ping to spike, but my own pc downloading doesnt
What are the "other devices"?
Wired, or wireless?
My pc is wired, and my phone is wireless. Right now no other devices are active other than those 2. The 'other devices' are anything other than my pc
So at the end of the phone's ping test, what was the min, max, and average?
I ran that ping test on my pc, whilst doing the fast.com test on my phone. I haven't measured ping on my phone, as I only really care about ping stability on my pc
Fine...what's the min, max, and average on the PC when running the test on the phone?
If this is a VDSL connection, I would set the Per Packet Overhead to 44.
Minimum = 12ms, Maximum = 66ms, Average = 27ms,
I tried setting Per Packet Overhead to 44, and nothing really changed
Nothing wrong with those numbers.
One test that I do (with no browsers involved) is a continous ping to a speed test server, while downloading a large file using wget (Linux distros run around 6 GB+).
Did you stop and restart SQM?
Yes, i did stop and start. I also noticed when i half the download speed in sqm settings, the ping spikes almost go away completely, is there anything else i can do other than this to prevent spikes?
You would need to determine where the latency is coming from.
Could be inside your network, inside your ISP's network, or outside the ISP's network.
I would download the free version of PingPlotter, and run tests to different endpoints.
It will give you a picture of what's going on along the route.
I will do that, thanks.
OK, that is good, you are using pppoe-wan in sqm.
Two things I forgot to ask for
a) a speedtest with sqm disabled
b) information from your modem about the sync
I will try to give a more detailled response later....
