Network Manager does not recover thernet connection on resume from hibernate

English Network/Internet
1

My TW KDE system uses Network Manager in preference to wicked for various reasons. This is a new install last week on a new HDD and now I find that on boot up although Network Manager works fine when I hibernate and then resume the wired lan connection which was in use prior to hibernate does not recover, trying to switch to wicked does not get the local connection up and a re-boot is needed.

Here is an extract from the journal which shows Network Manager from boot through to resume failing (newest entry first)

I have found that wicked will resume OK and regain the wired connection following a resume however I do not want to use wicked as a permanent solution as configuring it and disconnecting and reconnecting the lan is not available via the GUI which is required here.

I found bug 1058872 which although refers to a wifi connection sounds very similar so I have added my comments to this bug.

Stuart

4

Just tested to see if disabling network in YAST prior to hibernate and re-enable following resume works and the answer is yes, the network comes back up OK. At least I have a workaround allowing me to keep Network Manager.

Stuart

5

Ethernet hardware and driver details?

/usr/sbin/hwinfo --netcard

Is unloading and reloading the driver sufficient with helping NM regain management of the interface?

6

Just to clarify how do I remove and reinstall r8169 which is the driver for my Realtek card? Do I use modprobe in some way?

Stuart

7

Yes, with modprobe…

modprobe -r r8169

modprobe r8169

If that works, it can be automated to occur for a suspend/resume cycle.

8

A custom script in the /usr/lib/systemd/system-sleep/ directory. For example


#!/bin/bash
 "$1" = "post" ] && exec modprobe r8169
 "$1" = "pre" ] && exec rmmod r8169
exit 0

For more info

man systemd-suspend.service

A similar approach with a custom service file…
https://forums.opensuse.org/showthread.php/510210-Ethernet-down-after-resume-Tumbleweed?p=2732293#post2732293

9

Manually issuing these modprobe commands works and the network comes up OK. One very minor issue is that my Network Monitor widget does not show the activity although the correct connection is shown.

OK so now I can add the workaround but hopefully this will get fixed properly.

Stuart

10

Bug #1058872 still shows as new and nothing is happening so I think I will open a new bug to report this issue.

One other question, does anyone have any idea as to how to get the network monitor widget working again after a hibernate/resume? When I look at the Monitor settings it does not show any interface to be selected after the resume, also removing and adding the widget still has no effect.

Stuart

11

I have just created bug #1080483 for this problem.

Stuart

12

I had network issues when creating this bug and apparently unbeknown to me I created 3 reports in all #1080481 and #1080482 as well as #1080483 which is now the only one. Thanks to Andreas for sorting this out.
