Hi Marcel, Hi Robin,
thanks for your answers.
I resolved the same problem 😉 on my systems I run the networkmanager and this works long time - I'm not sure but I think the problem was that systemd gets or starts its own revolver service. After disabling it and deleting the linked resolve.conf the networkmanager creates it after a restart again and it works.
In Arch it's all about IPv6 it seems, so I did not want to disable it. Instead I deleted the old resolve.conf (it was replaced automatically by systemd). I replaced one (probably wrong) reference to IPv4 with IPv6 in my config, and started and enabled the network service again.
Now pinging works for both protocols, and my internet connection went from incredibly slow to more or less acceptable.
So yesterday it worked, pinging IPv6 adresses as well as having acceptable internet connection speed. Today not anymore, although I did not change anything (ok, wasn't there a kernel update yesterday?)

Hi,
seems like a ipv6 related problem. Your DNS Lookup is v4, first ping is v6 and second ping is v4 again. Try to ping the ipv4 address of google.com. But im pretty sure this is not arch related.
Maybe you should try to disable ipv6 system wide and then check if it works.
Cheers, Robin
Hello List, sometime age my msmtp imap connections just stopped working. Investigating the cause, I checked quite a lot of things, and came across the ping "100% package loss" problem:
