I've run into this with my x220 which was recently upgraded to Xenial as well. It is not consistent; it happens at maybe 1 out of 3 suspend/resume cycles.
Removing and reinserting the iwldvm module also fixes the issue, but kudos to Haw for noting that it doesn't seem to be a lower-level bug but rather in NM itself; as he suggests, a `sudo wpa_cli resume` triggers a reconnection. Toggling the kill switch does not cause a reconnection to happen, nor does disabling and reenabling wifi. The UI symptom is that the list of available networks in the dropdown does not update; either a single item or no item is displayed, and no reconnection happens (regardless of whether or not the item displayed is one which you have associated with before). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1556357 Title: WiFi fails to resume after suspend; Race with wpasupplicant / wpa_cli resume?
