[SOLVED] network interface does not appear at boot

After the last update, I have no Internet connection at startup. The interface "enp3s0" doesn't appear by giving "ip a" but only the loopback interface. In part I solve by giving from root:

# modprobe r8169

This loads the drivers for the Ethernet card for me and the connection is activated. These are the messages found in dmesg related to the driver:

[   74.876682] r8169 0000:03:00.0 eth0: RTL8168h/8111h, 24:4b:fe:56:8e:9a, XID 541, IRQ 108
[   74.876691] r8169 0000:03:00.0 eth0: jumbo features [frames: 9194 bytes, tx checksumming: ko]
[   74.881642] r8169 0000:03:00.0 enp3s0: renamed from eth0
[   74.951032] Generic FE-GE Realtek PHY r8169-0-300:00: attached PHY driver (mii_bus:phy_addr=r8169-0-300:00, irq=MAC)
[   75.141575] r8169 0000:03:00.0 enp3s0: Link is Down
[   78.848350] r8169 0000:03:00.0 enp3s0: Link is Up - 1Gbps/Full - flow control off
[   78.853353] r8169 0000:03:00.0 enp3s0: Link is Up - 1Gbps/Full - flow control off

The last 2 messages refer to after loading the driver with the previous command.
I also tried to insert in

/etc/modules-load/r8169.conf:
r8169

But this does not work. At startup I still have to manually load the driver to get the connection.
How can I solve this?

Re: [SOLVED] network interface does not appear at boot

You most likely have a blacklist from installing one of the alternate versions of the driver (... e.g. the r8168 package) at some point, check /{etc,usr/lib}/modprobe.d

Yes. there was an entry in /usr/lib/modprobe.d where the r8169 driver was blacklisted. i removed the entry. But checking with pacman there are no drivers for "r8169" but only for "r8168" , installed by the system. Before the last update I never had any problems.
This is the output of lshw:

Re: [SOLVED] network interface does not appear at boot

Yes r8168 is an alternate driver for more or less the same chipsets because the r8169 used to have some issues. If r8168 is now not loading anymore but you have no actual issues with r8169 from the kernel itself you can remove the r8168 package.

I removed the "r8168" package, rebooted, and now everything is okay.
Thanks for your help and best wishes for the new year!

Re: [SOLVED] network interface does not appear at boot

the r8169 driver comes with the kernel, so is always present .

Please post the output of

$ lspci -knn

.

Also please use [ code ] tags for the output.
see https://bbs.archlinux.org/help.php#bbcode .

Edit : too slow

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

This is the output concerning the network card:

Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev 15)
        Subsystem: ASUSTeK Computer Inc. PRIME B450M-A Motherboard [1043:8677]
        Kernel driver in use: r8169
        Kernel modules: r8169

This is the output after removing the old driver and rebooting. All ok I would say. :-)
