Configuring QoS for specific program

[moeller0]

it’s just when I have other people on my network I sometimes get ping spikes , well that is a gaming application, so latency is an issue there.

If I might ask, how many other users and more important how many (concurrently active) devices?

@anon11948778

Currently I have 10/ sometimes 13mbps down on a good day, and 680kbps up.

Could you report the sync rates as reported by your modem please?

@anon11948778

So I guess it just caps downloading speed when that other person on my network is using up all the bandwidth. My application takes about 180 kbps down and 50kbps up speed, so I just need to prioritize that application’s traffic, I just don’t know how.

You could try dscp marking, but I belive there might be something easier (but slightly more approximate) that might work for your situation.

@anon11948778

I would greatly appreciate any help, and well, if you try to explain me how, I don’t understand many terms,

I will try, but uou will need to do some reading first, please start with https://lede-project.org/docs/user-guide/sqm. I have alas no time for IRC or on-line video connections.

So I hope you have lede running on the archer then? Could ypu log into the router via ssh (on windows you can use putty for that). And type the following commands into the terminal window and copy and paste the output from the terminal window here into the forum: (only execute the parts between the double quotes ")

1. "cat /etc/config/sqm"
2. "cat /etc/config/qos"
3. "tc -d qdisc"
4. "tc -s qdisc"

That should give a decent idea about the capabilities of your link. Then please run a dslreports speedtest (see https://forum.openwrt.org/t/sqm-qos-recommended-settings-for-the-dslreports-speedtest-bufferbloat-testing/2803/7 for recommendations how to configure that test and how to report the results here, with your link I believe you might need to set the "No. upload streams:" to 8 or even to 4 though)

To add to the topic, I have no problem with my latency in the application, as long as there are no other people on network, and well, when they are there, it’s not always there, but when it becomes too often, you definitely notice it, definitely in evenings, so, since the applications takes about 10% or less of bandwidth provided by my ISP , I thought the ping and data required by it could somehow be prioritized. Thank you.

In theory prioritization is a decent solution, it is just that in reality that is much harder to do reliably. But assuming you do not share your internet with too many people/devices is to follow the recommendation of the "Making cake sing and dance, on a tight rope without a safety net" section of the user guide. That will aim to fairly divide the bandwidth between the concurrently active users (actually IP addresses), so typically if there are less than 10 concurrently active devices in your network you should get the 10% of bandwidth you need (you will however need to make sure that no other application on your gaming computer uses significant amounts of bandwidth, as all traffic from your computer will be treated to that imaginary 10% of the available bandwidth share).

I recommend to try to configure that and then test how well your games works with other users concurrently active. With a bit of luck that might be good enough for you to not having to bother with the more difficult how to prioritize on a per-application basis.
