Title:
Regression: WiFi connection reconnects, but dead, after waking from
standby
Status in network-manager package in Ubuntu:
Confirmed
Bug description:
Bug introduced somewhere between Ubuntu 14.04.3 and 16.04.1
If my Thinkpad T420s awakes from standby, very often the last
connected WiFi network is reconnected immediately, but the connection
is dysfunctional.
ifconfig shows a valid connection with an IPv4 address assigned for
the wlp3s0 interface.
But there is no traffic, no success on DNS queries on the connection.
If I reconnect by clicking the connection in the nm-applet menu, all
is fine again.
