I am having trouble resolving DNS only at my parents place which I really do not understand. It is the only place where I have that problem.
My feeling is that systemd-resolved
is not configured properly.
When I use the "broken" wifi I see A LOT of these messages:
Using degraded feature set (TCP) for DNS server 192.168.0.1.
As soon as I switch to my hotspot there just a couple of them.
Here is my /etc/resolv.conf
nameserver 127.0.0.53
options edns0 trust-ad
Here my resolvectl status
resolvectl status --no-pager

I can ping public internet:
ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
64 bytes from 8.8.8.8: icmp_seq=1 ttl=116 time=48.6 ms
64 bytes from 8.8.8.8: icmp_seq=2 ttl=116 time=41.1 ms
I have enabled debug
logging for systemd-resolvd
since this is my hunch but could be wrong.
Happy for any hints!
sudo journalctl -b 0 -u NetworkManager
. Readman journalctl systemd-dnsmasq
.dnsmasq
running.NetworkManager
looks pretty okay from my first glance: pastebin.com/jMkt9DqR
