I have the same problem, but only some dns queries stop working. For instance, google.com works fine, while duckduckgo.com doesn't.
When trying to ping a server that doesn't work, it fails immediately with the message (translating from Polish, sorry): This name or service is unknown. I have seen workarounds like restarting dnsmasq, or disabling it in /etc/NetworkManager/NetworkManager.conf, but these don't work for me. What works is doing dpkg-reconfigure resolvconf. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1631241 Title: Name resolution stops working after resume from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1631241/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
