This issue has been present again with systemd on Ubuntu 15.04. I have a
clean install of 15.04 on a Lenovo Y50-70 with an Intel Wi-Fi AC 7260
and I need to run sudo service network-manager restart in order to
bring back internet access. This issue was not present with 14.10 and
before. I first
Andre, as I described in the previous comment, this bug is now useless
because it has been abused for too many tasks.
Please file a new bug, so that your logs and information can be
collected.
Thanks.

Twente, that's because this bug is useless for fixing any issues -- I
originally filed the bug with 13.10, which has been EOL for 1.5 years.
Others added completely unrelated bugs here along the way rather than
filing new bugs for their issues. Once this turned into a wasteland of

The workaround I am currently using is to use the b43-driver instead of
wl (sudo rmmod wl ; sudo modprobe b43). This means forgoing support for
802.11n, I think. At least I can no longer see 5GHz networks. However,
it also means that the network reliably reconnects after suspend and
resume, in my
I have same issue with Macbook 4,1 (Early 2008).
I noticed same symptom as Martin (activated - unmanaged after resume)
and looking network manager code (do_sleep_wake() in nm-manager.c) it
seems to be related to wake on lan stuff.
So, I modified nm_platform_link_get_wake_on_lan() to always
This sounds similar to bug 1450396. Could you try and add this line
ethtool -s eth0 wol g
to /etc/rc.local before the exit 0, reboot, and see if that helps?

I tried this, but it didn't help for me. I don't have wired LAN in use
(eth0 is not connected), so I also tried to adapt change for wlan0, but
ethtool doesn't give any info for wlan0 and setting wol mode doesn't
work:
$ sudo ethtool wlan0
Settings for wlan0:
No data available

Reconnecting wifi worked fine here until the system upgrade to 15.04
(vivid). Since then, after suspend and resume wifi does not work almost
always.
No wifi networks are shown in the network manager menu then, and I have
to either switch networking completely off and on again, or select
“connect
Same problem on Lenovo E145 with BCM43228 wifi. Reconnecting by turning
wifi off and on sometimes works. Have not tried restarting
networkmanager.

I just installed 15.04 on a lenovo E330 with a r8169 wireless chip and
have this problem. Wifi connecting on startup, but after suspend, I have
to deactivate wireless and reactivate to get a connection. Never had the
problem with neither 14.04 nor 14.10.

The workaround is to switch to upstart by default.
Can be done like this:
Install the upstart-sysv package, which will remove ubuntu-standard and
systemd-sysv (but should not remove anything else -- if it does, yell!),
and run sudo update-initramfs -u. After that, grub's Advanced options
menu
This same bug happens on a Macbook pro 8,1 with Ubuntu unity 15.04
After a suspend the wifi is disconnected. Restarting the network-manager or
toggling wifi off/on via the system tray solves the problem. This does not
improve the user experience.

The first patch above does nothing to the bring the connection back up
after building my own set of packages. There does seem to be a race
condition of some sort between the supplicant and NM but I'm not able to
track it down appropriately.
I'm attaching my debug logs to this bug report in the
Fran, the first patch looks promising. The second patch looks unrelated,
but cherry-picking it can't hurt anyway I guess. If you can test this,
please do (I just returned from holidays and have a giant backlog).

pitti, will you build packages with these patches or should I test them
in my local machine?
