Weird connection errors on all server. - vogi - 04-12-2026
Hello,
currently am playing Xonotic on my Framework 12 with Debian Stable and am seeing weird connection errors.
Every now and then (the timing is variable, maybe every 10 minutes) I get weird server lag. It happens on all the servers though, so I expect it be a problem on my client. It behaves typically to when you lose connection to the server: the position of ever player only gets updated every second or so, the framerate remains stable, after 10 seconds it goes back to normal.
Did anybody else have this kind of problem? I only have that with xonotic.
Have a pic of the netgraph attached, but i doubt thats helpful.

If you're on wifi it could be background scanning, some OSs / tools instruct the hardware to scan for other access points (or bluetooth devices) even with a good connection to the current AP (as a crude/legacy way to implement roaming) but consumer-grade wifi radios can only do one thing at a time so it causes ping spikes or packet loss.

I use QoS in my router, just to cap it.
Back in the UT days I had to define rx/tx manually to get a steady connection, but now I just use QoS to deal with "bufferbloat". I cap my 1Gb/s to 750 Mb/s.
Have no idea if it will help you but it cannot hurt. You may look into TX and RX network interface buffers if you want to test further options.
In UT I had to use something like rx 4096 tx 8192, but I still have no idea if that is an issue with your distro or framework.
Again, never really had any issues with xonotic, so I am just speculating.
Did you build your client from git? If not, try to build a fresh one. And as bones said, wifi could be an issue if that is what you use.
sysinfo?
