Hi,

I made a mess of it.
Wanted to stop the RPI bookworm wifi, followed some instructions and no there's no DNS lookup anymore.
I can ping 8.8.8.8 and it answers
When I ping google.com there's: Temporary failure in name resolution
ifconfigs shows:

Code:

docker0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500        inet 172.17.0.1  netmask 255.255.0.0  broadcast 172.17.255.255        ether 02:42:cd:26:57:4f  txqueuelen 0  (Ethernet)        RX packets 0  bytes 0 (0.0 B)        RX errors 0  dropped 0  overruns 0  frame 0        TX packets 0  bytes 0 (0.0 B)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500        inet 192.168.2.104  netmask 255.255.255.0  broadcast 192.168.2.255        inet6 fe80::da3a:ddff:fe08:c21b  prefixlen 64  scopeid 0x20<link>        inet6 2a02:a443:8cfd:1:da3a:ddff:fe08:c21b  prefixlen 64  scopeid 0x0<global>        ether d8:3a:dd:08:c2:1b  txqueuelen 1000  (Ethernet)        RX packets 10826  bytes 3099087 (2.9 MiB)        RX errors 0  dropped 0  overruns 0  frame 0        TX packets 9487  bytes 5790692 (5.5 MiB)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536        inet 127.0.0.1  netmask 255.0.0.0        inet6 ::1  prefixlen 128  scopeid 0x10<host>        loop  txqueuelen 1000  (Local Loopback)        RX packets 3358  bytes 279867 (273.3 KiB)        RX errors 0  dropped 0  overruns 0  frame 0        TX packets 3358  bytes 279867 (273.3 KiB)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
When I do:

Code:

sudo nmcli device mod eth0 ipv4.dns "8.8.8.8 8.8.4.4"
the answer is:

Code:

Error: Reading applied connection from device 'eth0' (/org/freedesktop/NetworkManager/Devices/2) failed: Device is not activated
