Title:
Wifi doesn't work after resume, fixed by forcing scan
Status in network-manager package in Ubuntu:
Confirmed
Bug description:
Often after resuming from suspend, my laptop (Samsung series 9) is
disconnected from the wifi and it doesn't seem to reconnect. Network
manager seems confused; it displays that it is connected, but it shows
the wrong access point (i.e. one of my neighbour's access points that
I don't even have the password for).
Running iwlist scan manually fixes the problem almost immediately and
network-manager starts showing the correct state (connecting, then
connected to the right AP).
Very similar to bug 1332904 but apport recommended filing diags on a
fresh bug report.
Wifi card appears to be "Network controller: Intel Corporation Centrino
Advanced-N 6235 (rev 24)" according to lspci.
