I flashed a second Krillin device to rc-proposed r335, the bug was triggered after just a couple of minutes.
Tony adviced using tcpdump, so I looked for some useful DNS related tcpdump commands, and that resulted in the log you can find attached INFO about the device: It has 1 SIM, which is currently locked (as I don't know its PIN, but I can get it if needed) ** Attachment added: "tcpdump_brokenDNS" https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1580146/+attachment/4666342/+files/tcpdump_brokenDNS -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1580146 Title: [touch] Internet connection stops working while WiFi is still connected To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1580146/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
