After some problems Lubuntu 17.04 will not connect to WiFi (no error message displayed) I finally got connected, but I still have no access to the internet.
I got an IPv4 address 192.168.1.89
I can ping that address from other computers on the network.
The Lubuntu (latest version 17.04) computer in question can ping outside the network, for example pinging google on this address worked ok:
ping 216.58.201.110
But the browser still gives me SERVER NOT FOUND
cat /var/log/syslog | grep -i dns
