Title:
No wifi after suspend/resume
Status in linux package in Ubuntu:
Confirmed
Bug description:
Similar to Bug #1154949 but occuring on release 14.04 LTS, after update from 13.04
Wireless connection will not resume after laptop has been reawakened from suspend mode on main Ubuntu start menu or closing laptop lid.
I have looked through and found several reports of a similar issue in earlier versions of Ubuntu, and believe it was patched?
I have attempted using graphical menu neither switch operates - shows the airplane mode switch in ON and wireless switch in OFF.
The laptop external wireless switch remains in ON position but no longer works.
I have tried RFKILL commands - no effect.
I have tried NMCLI commands - no effect.
