2016-04-27 Thread lauricat
I have this bug as well in a clean MATE 16.04 install.

 x220, Intel 6205 wireless . Using the firmware iwlwifi 18.168.6.1

Various things like #12 sudo iwlist wlan0 scan - does not work for me.

Also disabling Wireless and/or networking via Network Manager - and re-
enabling does nothing.

Nor does using hardware on/off/on for wifi make a difference.

Rebooting fixes it.

I have tried this fix

http://ubuntuforums.org/showthread.php?t=1984317&page=3

[which is a seperate fix for the Intel Wireless hardware flaky WiFi
connection - not related I feel]

Subsequently I have gone back to 14.04 MATE and works perfectly!

Is this a systemd issue perhaps?

I can confirm that this bug is eliminated in 15.10.
Unfortunately another old bug reappeared (random disconnect).
I will look into this in more detail.

For me it is solved.

2015-10-01 Thread Wolf Rogner
back to suggestion #12:

It does not fire (still don't know why)

However, running iwlist scan (as sudo) DOES reconnect.

Today I connected to another network (which I use regulary. The
connection was established immediately after resume.

After putting the machine to sleep again, no reconnect occured after
resume.

Thus my observation:

If after wake-up the network environment is the same, network manager DOES NOT 
reconnect.
If after wake-up the network is different (other SSIDs or SSID not found) a 
scan is launched automatically and a reconnect occurs.

I have a similar symptom; doing

  sudo iwlist wlan0 scan

after resume tickles NetworkManager into seeing there's wifi available
which it then connects to.

I did not test switching back to Upstart, however I am using 
xfce4-power-manager as mentioned in Comment 7.
If I close the lid, wifi does not work on resume, however if I do:

  pkexec xfce4-pm-helper --suspend

wifi is correctly restored on resume.

[Bug 1448555] Re: network-manager does not autoconnect to wifi network after resume from suspend

2015-08-19 Thread Wolf Rogner
In kernel 3.19.0-26 the connection was reestablished sometimes (could not 
reproduce a pattern)
in kernel 3.19.0-27 (updated today) the situation is as initially described. 
The connection does not get reestablished after a resume, regardless of wheter
a. I previously disconnect and reconnect in the NM-applet
b. restart service NetworkManager

The log files demonstrate complete different behaviour on resume,
restart of the service or reconnect from the applet. I cannot see any
similarities at all.

Should I expect some reuse of code and behaviour or is this a complete
misconception?

I am experiencing the problem as originally described.

I have discovered that using the b43 driver module instead of wl fixes
this problem: sudo rmmod wl ; sudo modprobe b43

However, this also makes any 5GHz networks disappear.

This makes me believe there is a bug in the wl module.

I'm having kinda the same problem. After suspend at work and resume after one 
hour at home, NM applet won't show my home networks at all - so no auto 
connection, of course.
If I do enable/disable wifi or try to connect to one of work wifi AP (which of 
course is not there but is still in the list in NM applet), then NM applet 
refreshes AP list and I'm able to connect.
I have nothing suspicios in pm-suspend log though.
It might be nm-applet issue maybe...

2015-06-06 Thread Plurtu
I have the same log as #4 which is definitely a different bug. The
network manager wakes prematurely before suspending causing it not to
wake when resuming. I experienced this on lubuntu 15.04 but could not
replicate it on Ubuntu 15.04. I isolated the problem down to xfce4
-power-manager which is responsible for suspending on lid close or
timeout (manually suspending with "systemctl suspend" works fine). It
seems to have issues with the recent change to systemd, switching back
to Upstart fixes the problem.

Additional observation:

Somehow upgrading the kernel did not happen. So the kernel stayed
3.19.0.15 for a while.

Other upgrades went fine. So for the last few days, I did not observe the 
phenomenon on this particular machine.
(Others, where the kernel war upgraded to 3.19.0.20 had the issue constantly)

After upgrading to 3.19.0.20 on this machine, the behaviour / issue
reappeared.

here is the syslog. Mind 09:53:21 where NetworkManager deactivates for
no reason.

I'm not sure if this is the same bug, but after upgrading to 15.04, I
have to "sudo systemctl restart NetworkManager" to get back my network
interfaces after a long suspend. If I test a short suspend/resume cycle,
like a couple seconds, it works fine, but when I open my laptop in the
morning I have to restart NetworkManager.

I attached a journalctl excerpt; I closed the lid last night at 20:29,
then opened it this morning at 08:09 and first tried the hardware
switch, then eventually restarted NetworkManager.
