I have a strange "high ping spikes" problem
I always have a ping of 8-20ms but from time to time (approx. 1x per minute but very differently) the internet on my work computer freezes for a few seconds
then my ping looks something like this:

Info:
- I have Kubuntu 22.04 LTS
- I have fiber optic connection since yesterday ... before that my network was very unstable. So I don't know if the problem was there before and I just didn't notice it or if it's just since the switch
- My computer is connected to a Fritz!Box via WLAN
- The problem occurs with two different WLAN sticks (different companies/models)
- The problem does NOT occur on other computers with Kubuntu 22.04 LTS (two computers, two laptops, also over the same Wifi)
System:
- Kubuntu 22.04 LTS (new installation used to be a 20.04 LTS ... Upgrades: 20.04 LTS >> 21.04 >> 21.10 >> 22.04 LTS)
- 128GB RAM --- AMD Ryzen 5950x --- Radeon RX 6600 XT
what I've tried so far:
- I have already changed wifi.powersave from 3 to 2 in /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
The following logs do not show any entries at the times in question:
- route
- journalctl -f
- journalctl -fu NetworkManager-dispatcher.service
- journalctl -fu NetworkManager.service
