- I had a decent connection over wifi - occasional stutter but totally manageable.
- Fiber internet with a high capacity wifi6 router
- Suddenly, I get ping spikes for 10 seconds.
- no other network activity at time that I’m playing.
- router is one room over.
- Only recent update is maybe a Fedora system update, or a Deadlock update.
- Please help. I don’t want to go beneath house to run cat6. It’s dark and there are spiders.


mtr is probably the best first step, it’ll let you know where the issue is happening.
You can also keep a terminal open with
# journalctl -frunning, it’ll show you a live view of your system log. This would make it easy to look over at the log when the lag is happening.# dmesg -wmay also be useful if your hardware is dying and restarting.
