I can induce a connection drop by changing the wireless channel on my router - this also produces a similar result (no auto reconnect) - it shows like it's trying for a minute or 2, and than shows the up/down arrows. Selecting the network manually connects immediately.
Here's the NetworkManager log: https://pastebin.com/CB6d8NP4 Attached is the debug wpa_supplicant log starting from the disconnect ** Attachment added: "wpa_supplicant log (debug mode)" https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1703838/+attachment/4914037/+files/wpa_sup%20failure%20to%20reconnect3%20debug -- 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/1703838 Title: Failure to automatically reconnect after drop - requiring manual reconnect, only successful after second try Status in network-manager package in Ubuntu: New Bug description: Using Ubuntu 17.04 (64 bit) Package version 1.4.4-1ubuntu3.1 This happened to me 3 times today: The connection drops and is not automatically restored, even though the network is visible in the nm-applet. Manually clicking on the network to connect, results in an animation of the nm-applet showing it's trying, but it gives up after a while and changes the icon to up\down arrows instead of the wifi sign. Clicking on it again, and selecting my network again, results in an almost instant reconnection, which implies that the computer should have known to do it automatically instead of requiring me to tell it to connect again (let alone twice). Here is the journal from a system startup: https://pastebin.com/hGrFEWiU And here is the journal from one such unsuccessful reconnect. I've added (*** comments ***) to mark where I've manually tried to reconnect (twice, second time successfully): https://pastebin.com/TAyt6McQ To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1703838/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
