Im using Ubuntu 16.04. I have some issues regarding DNS resolving. It only happens at my home network. However, my other wifi devices work fine. After startup, DNS resolving doesn't work for about 5/10 minutes. Then it starts working. Pinging to addresses like 220.127.116.11 work fine, but ping to hostnames doesn't (so I guess DNS issue).
My /etc/resolv.conf doesn't change before and after the issue, it keeps the same. I added "nameserver 18.104.22.168" but no change. It has 3 nameservers (2 of them got by DHCP).
On other networks my system works ok, DNS works from the beginning. Chrome status bar says "Resolving host..." and then timeouts. Any tips so I can debug while the issue is present?
