No internet connection with kernel upgraded above 4.16.11-1(-ck-k10)

This happened first with the next upgrade after 4.16.11-1, but I assumed it's just something wrong with package or whatever. But now a newer version came out, and internet connection is still down.
I know it's not the official Arch kernel, but I just want some pointers what can I can do to troubleshoot and see why the connection is gone after the upgrade. I obviously can't do it with upgraded kernel, as I can't access internet...

Thanks in advance (ps.: I might install the newest arch "vanilla" kernel, to see if it's also happening there.

There's no info at all on your hardware or setup in general.

Simply from the symptoms it reads like you simply don't have your boot partition mounted during the update and thus have an incompatible set of modules with your kernel. Do the versions of

uname -a
pacman -Q linux-ck-k10

match after an update and a subsequent reboot? If they don't you have to ensure that the kernel image gets written to the correct place so that you don't start an old kernel even though you have newer modules.

If you are sure it isn't that post information on your hardware, how you are connecting to your network, and a journalctl -b from the failing kernel.

Mod note: Moving to NC.

Can we also have:

ip link

This should tell whether it actually detects a device.
Also, are you using a wired or wireless connection?

Here's some info you wanted:

uname -a

Linux foucault 4.16.11-1-ck-k10 #1 SMP PREEMPT Tue May 22 17:37:37 EDT 2018 x86_64 GNU/Linux

pacman -Q

linux-ck-k10 4.16.11-1

ip link

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
    link/ether 50:e5:49:53:d2:e9 brd ff:ff:ff:ff:ff:ff

BTW I only have one partition, so that shouldn't be the problem...
