Not seeing this on my machine, so it may be kernel related.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1760073

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Network issue is either kernel or Network Manager.

After the issue occurs we need to see the current 'dmesg' log (which will show if devices resumed successfully) and /var/log/syslog (where Network Manager is very verbose).

We also need to know which devices the system has:

lspci -nnk
lsusb

added a file to /lib/systemd/system-sleep with

#!/bin/sh

set -e

if [ "$2" = "suspend" ] || [ "$2" = "hybrid-sleep" ]; then
    case "$1" in
        pre) true ;;
        post) sleep 1 && service network-manager restart ;;
    esac
fi

and network coming out of suspend works ok.

[Kev Bowring (flocculant)]

then it didn't

[Kai-Heng Feng (kaihengfeng)]

How did you suspend the machine?

[Kev Bowring (flocculant)]

From the shutdown menu we use.

suspend - there wasn't.

[Kai-Heng Feng (kaihengfeng)]

It's because this:
[ 2663.907630] r8169 0000:03:00.0 enp3s0: link down
[ 2663.907639] do_IRQ: 3.34 No irq handler for vector

[Florian W. (florian-will)]

Since updating to bionic, I notice the same symptoms (network not working after suspend).

I'm adding this comment to note that this makes my network come up again, I'll try to add this as a post-suspend script as described above:
$ sudo modprobe -r r8169
$ sudo modprobe r8169
(Suggested in https://ubuntuforums.org/showthread.php?t=2386503 )

My journalctl looks a very little bit different, but I guess it's simply because we don't use exactly the same mainboards, so the IRQs differ:

I have added a link to the upstream kernel.org bugzilla, I believe it's the same bug.

I have a SONY VAIO laptop model VPCEB3M1E. After upgrade from kubuntu 17.10 to kubuntu 18.04 i have this problem: Ethernet disconnect after suspend. My ethernet controller is: Marvell Technology Group Ltd. Yukon Optima 88E8059 [PCIe Gigabit Ethernet Controller with AVB] (rev 11) and the kernel module is sky2.

I try: sudo modprobe -r sky2 and then: sudo modprobe -i sky2 and the ethernet working since the computer goes in sleep mode. After suspend the problem again exists.

The linux kernel is 4.15.0-20-generic

[kris (ski007)]

all new 4.15.0-X.X kernels have this error :-(
but I use this script and it's OK
but we must finally fix it .............
create and edit:

/lib/systemd/system-sleep/restore_connection
...............
#!/bin/sh
sleep 5
case $1/$2 in
post/*)
sudo systemctl restart network-manager.service
modprobe -r sky2
modprobe sky2
;;
esac
...........give executable rights.............

chmod +x /lib/systemd/system-sleep/restore_connection
