Workaround: Edit /etc/NetworkManager/NetworkManager.conf and remove the line "dns=dnsmasq". -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1633912 Title: Problem with DNS resolution after suspend Status in network-manager package in Ubuntu: Confirmed Bug description: I upgraded my laptop to 16.10 yesterday. Sometimes after suspend I have network issues, one time I was not able to connect to a wifi network (might report another bug if this occurees again, but maybe it is related, as in network-manager is in some broken state after suspend). Here is whats happening pretty often: After resume from suspend I have a solid network connection, no problem to ping machines in LAN or on the internet. But DNS resolution is broken until I restart the network-manager service. I ran ubuntu-bug while DNS was broken, so if anything gets log-ed it should be in there.
