I seem to be in a similar position to Nicolas. Before a suspend, with wifi working, WWAN is disabled according to 'nmcli nm'. Then, after suspending, with wifi not working, WWAN is enabled.
However, sometimes wifi doesn't work even after restarting my Dell laptop and WWAN is disabled after restarting regardless of whether or not wifi is working. So the WWAN enabled/disabled may be a red herring. I've also noticed link=yes in the 'configuration' entry for the wireless adapter section of 'sudo lshw -C network' when wifi is working but link=no when wifi does not work. But maybe the link attribute is just another way of indicating whether it's working or not (i.e., an effect rather than a cause). I don't know what the 'link' value means. Wifi used to reconnect for me without any problems on my Dell in 12.04 LTS. It's only since upgrading to 14.04 I've had these problems (http://ubuntuforums.org/showthread.php?t=2218612). Interestingly, wifi fails to reconnect after suspending if I'm running off the 14.04 Live CD too. Presumably wifi would reconnect successfully after suspending if I was running off a 12.04 Live CD but I haven't tried that. Maybe if we ran these or other commands before and after suspending on 12.04 and 14.04 Live CDs we could isolate what's changed. ** Attachment added: "before_suspend_wifi_working.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1286552/+attachment/4096909/+files/before_suspend_wifi_working.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1286552 Title: No wifi after suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1286552/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
