Any clue on this. my notebook has been having problems with networking. My clue is that I am using a USB wifi in place of the built-in wifi -- which is faulty (poor performance and probably not working on certain frequency band). Occasionally, I forgot to bring my USB, and has to turn on the builtin wifi. But, I almost never intended to run two wifi adapters at the same tme.
But, even the interface is down, it is still configured. My theory is it has something to with the various networking problems I have been having. In particular with public wifi -- many times I dont get the wifi login redirection . In several Starbucks, it will not see the Starbuck signals once it lost them (probably just after network in- active sleep). Though, it can acquire the next door signals but not re- acquiring google-starbuck. Very weird. I suspect that multi adapter related because the original poster also run multiple networks. I am not really. But, I am also a developer. I plug in my phone to PC to either develop app and such, or use its data in a pinch when my wifi does not work. I am fairly technical -- used to work on TCP/IP and such 20 years ago. If someone wants to cooperate with me... i will pitch in. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1290217 Title: The overwriting error message was: Key file does not have group 'connectivity' Status in network-manager package in Ubuntu: Confirmed Bug description: Looking at /var/log/upstart/network-manager.log, that error is written: (NetworkManager:969): GLib-WARNING **: GError set over the top of a previous GError or uninitialized memory.
