Internet connectivity keeps dropping but wifi is connected

My internet connectivity keeps dropping every few minutes and then I get reconnected again after a short while.
Output from

ping 8.8.8.8

when this happens is:

64 bytes from 8.8.8.8: icmp_seq=1348 ttl=117 time=50.4 ms
64 bytes from 8.8.8.8: icmp_seq=1349 ttl=117 time=49.5 ms

64 bytes from 8.8.8.8: icmp_seq=1361 ttl=117 time=49.4 ms

The output from

journalctl -f

is:

Re: Internet connectivity keeps dropping but wifi is connected

could you post the output of find /etc/systemd/system   ??

I've tried reinstalling Arch already and I still have the same problem. Doesn't happen when I'm on windows (same machine).

Re: Internet connectivity keeps dropping but wifi is connected

Please avoid that - it's not going to magically fix stuff and you're creating a moving target.

Doesn't happen when I'm on windows (same machine).

3rd link below. Mandatory. Reboot windows (and linux) properly twice (voodoo reasons) - possibly (if you can) also the access point (router)

If that's not the cause, please post a complete system journal of an affected boot ("sudo journalctl -b -1 | curl -F 'file=@-' 0x0.st" for the previous one)

Re: Internet connectivity keeps dropping but wifi is connected

May 21 12:36:04 kyljmn NetworkManager[365]: <info>  [1653107764.1664] manager: NetworkManager state is now CONNECTED_GLOBAL
May 21 12:36:59 kyljmn systemd[1]: Stopped target Network.

The only but very suspicious thing inbetween is the docker0 NIC and resulting iptables.
=> Disable docker, the wifi looks unsuspicious but I guess docker derails the netfilter (firewall)
