[Bug 807111] New: NetworkManager does not reconnect to WLAN after resume
https://bugzilla.novell.com/show_bug.cgi?id=807111 https://bugzilla.novell.com/show_bug.cgi?id=807111#c0 Summary: NetworkManager does not reconnect to WLAN after resume Classification: openSUSE Product: openSUSE 12.3 Version: RC 2 Platform: i686 OS/Version: SUSE Other Status: NEW Severity: Normal Priority: P5 - None Component: Network AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: Greg.Freemyer@gmail.com QAContact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux i686; rv:19.0) Gecko/20100101 Firefox/19.0 KDE 4.10 NetworkManager 0.9.6.4-5.2.1 If I close the lid of my laptop it hibernates. When I open the lid it resumes. I am asked for the KDE Wallet password. All of that is good. The bug is that my WLAN connection is not re-established. I simply use NetworkManager to drop the connection and re-establish a new one. Note that this is NOT using 2 different locations or different WLANs. I close the lid with my home WLAN in use and open it back up still in my house. Reproducible: Always Expected Results: I expect the WLAN connection to be re-established automatically one the KDE wallet password is re-entered. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

As a solution (or a workaround), i have removed pm-utils, and that has resolved the problem here. Thing was that with that change, suspend is handled with pm-utils, and they are pretty slow to do it's job, as NM managed to disconnect and reconnect before machine entered suspended state. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

There is the same pm-utils sleep.d script in 12.3 and in 12.2. If dropping pm-utils were a solution, the mentioned SR would not be needed at all. As long as pm-utils are supported, this is expected to work correctly. Could you - stop NetworkManager (systemctl stop NetworkManager) - start it manually using NetworkManager --no-daemon --log-level=DEBUG - suspend/resume and provide resulting output. You may want to redirect output to file or start it under "script" command. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Under 12.3 you should be able to do systemctl start hibernate.target In the worst case you can directly do echo disk > /sys/power/state -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Also it is 0.9.7 and we have yet 0.9.6. Also at least attached log shows that NM reestablish network connection after resume.

I assume that is NM from 12.3 Gold. I still loose connectivity when closing/re-opening my laptop. By chance, this time I started a ping before closing/re-opening my laptop.

The best case was the second one :) With NM receiving signals I sporadically get permanent Connecting indication in panel icon (GNOME), even though connection is actually established. May be it is driver/card problem?

I just updated to the latest patches including NM: i | NetworkManager | package | 0.9.6.4-5.12.2 | i586 | openSUSE-12.3-Update I still have the problem. BTW, per the KDE NM panel, all is good after hibernate/resume. It is my connectivity that fails. If I start up a ping, it fails until I manually drop the WLAN connection, then re-establish it.

If I suspend my laptop with the network cable plugged in, move it to a different network, plug that network cable in, and resume the laptop, ifconfig shows the IP address from the old network. If I then unplug the network cable, wait 5-10 seconds, and plug it back in, NM picks up the new network; likewise, if I simply wait 5-10 seconds before plugging the network cable in on the new nettwork, it also picks up the new network. I would think NM should recognize that there was a suspend/resume event and automatically try to reconnect rather than assume there hasn't been any change (if that's what's happening). I notice that if I unplug the network cable in general, knemo recognizes that the cable is unplugged, but the NM icon doesn't show it as disconnected for 5 seconds or so. All of this worked fine under OpenSUSE 12.2. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
