I have issue on Ubuntu 17.04, Internet works fine and after a few minutes, sometimes hours suddenly it stops working. Also sometimes when I run the system in the morning, the internet is not working from the beginning.
In both cases I have message in chrome browse:
DNS_PROBE_FINISHED_BAD_CONFIG
Worth to add, I can ping ip adress. For e.g ping wp.pl - not working but ping 212.77.100.101 - working.
Also internet in this time working fine on other devices - android smartphone, desktop PC with OpenMandriva or even on the same device but on other OS - Fedora 25. So look like this is bug in Ubuntu 17.04, but I can't fix it. For Ubuntu 17.04 help me only restarting router...
I trying fix it like in this topic: DNS_PROBE_FINISHED_BAD_CONFIG error in Ubuntu 14.04
but any solution not working for me.
dmesg | grep -i dns
If the result is lenthy, post the output here and give us the link: paste.ubuntu.com
