Intentional delay to fix desync in csgo using Netem in OpenWRT

[dermodemon]

Hello guys.
My goal is to fix bad desync in csgo.
I use vpn to make a little bit of delay(it's SOO much better than without vpn) but i decided to stop using it.
I update my firmware on the router to OpenWRT. Installed SQM, Netem etc.
In the command line i put:

tc qdisc add dev eth0 root netem delay 2ms

Now my ping results are floating. Instead of stable 3ms(1ms+2ms) i have something like this:

My question is how to make it more stable. And overall am i doing all of this right?
How to configure only outbound or inbound packets? How does it works

When I used to have a small router with no option to configure much, I was using Clumsy where the lag is created directly from my pc

Then I built my own Router Firewall which is more powerful and did it directly from the network

The reason why yours is not stable is probably your router is probably not powerful enough to maintain. Try Clumpsy

hey, where can i change these firewall settings? is it built in your router? or this is windows program?

Am i doing it right? want to add 20ms delay

Do you have Codel instead of Cake to manage your queueing?

I did build my own router, what I did I bought a cheap factor computer (used) with a CPU that can easily handle a 1Gbps fibre connection, well Mine can handle up to 10Gbps easily but I also to make sure to check on the power consumption. Anyway, I have a Core i5 6500 with 8 GB of ram. The little pc did cost me $120 which is way more than those "GAMING ROUTER" and coupled with OPNsense (similar idea as OpenWrt) it's a little beast.

Queue's delay parameter actually not delaying packets
Here is man for fq_codel:

Same for any queueing mechanism - its not delayer but parameter for packet dropping, so messing with this parameters without knowledge can lead to packet drop.

For actually delaying packets you need netem module.

P.S. you can only control egress packets

Guys it's all on ISP side but be prepared that they gonna pretend like dumbs and ask you for speedtest. It's all about congestion control and UDP traffic handling. By looking how the game behaves it is so obvious because it's being extrapolated all the time.

yeah i have something like that

Is there any recommended intentional delay that fixes desync in csgo?
