I've been having that issue for awhile, on Ubuntu 12.04. I haven't yet seen it on Ubuntu 16.04, which is what I'm using now.
It does not connect to the Internet at times, on this one and another one (running Ubuntu 12.04). Usually if I take out the USB WLAN adapter and put it in another USB port, it works, at other times only works for a minute. I'm not sure if that is related, but worth looking into. - Blossom ** Summary changed: - NM puts up "Authentication required by Wireless Network" dialog even if previous identical dialog was canceled + NM puts up "Authentication required by Wireless Network" dialogue even if previous identical dialogue was cancelled -- 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/824998 Title: NM puts up "Authentication required by Wireless Network" dialogue even if previous identical dialogue was cancelled Status in network-manager package in Ubuntu: Triaged Bug description: Oneiric annoys me sending messages "Authentication required by Wireless Network" ad infinitum. I did not aks Oneiric to connect to a wireless access point. Lucid was more intelligent and stopped annoying me after a while after I had told it not to connect to this wireless network. I expect that Oneiric GNOME 3 learns at least after the third denied message that I am connected via Ethernet and do not wish a wireless connection.
