Re: [SOLVED, driver issue] Ethernet enp6s0 broken after update.

Please stop NM (and systemd-networkd and everyhing else) and try just "sudo dhcpcd -dB" and post the output.

Re: [SOLVED, driver issue] Ethernet enp6s0 broken after update.

I'm lost, I even installed Arch LTS but the driver needs to be for the LTS kernel as well, so I'll try tomorrow. After a few reinstalls of the driver I was able to get a steady connection with OpenWRT but after opening archlinux.org in the browser the connection drops completely

There're no r8168 errors

You can also try r8169, but esp. recently that was the one causing trouble - and I don't like the weird dhcp behavior so lets get that under control first.

In both cases I have opened w3m, navigated through archlinux.org, and then opened firefox and opened a few websites. In both cases the internet gets cut off after those lines from dhcpcd:

Re: [SOLVED, driver issue] Ethernet enp6s0 broken after update.

Running dhcpcd alogn NM isn't an option at all, so we ignore that.

Re: [SOLVED, driver issue] Ethernet enp6s0 broken after update.

That output is now pointless.

When using *only* dhcpcd (not NM!) and the "internet fails", post the outputs of

ip a
ip r
ping -C1 _gateway
ping -C1 192.168.1.1
ping -C1 8.8.8.8
ping -C1 google.com

Wild guess: disable IPv6, https://wiki.archlinux.org/title/IPv6#Disable_IPv6 "ipv6.disable=1"

Re: [SOLVED, driver issue] Ethernet enp6s0 broken after update.

What is the behaviour of NIC without dedicated r8168 driver?

Could you show logs, more globally?

journalctl -q -b -p 3..3
journalctl -q -b -p 4..4
ip r

I also have The F..g Saint R8168 NIC xD There were problems about 2013. I'm using only r8169 built-in kernel module with systemd-networkd.

Look here: 3.5 and 3.6 section, for IOMMU setting in BIOS:
https://wiki.archlinux.org/title/Networ … 8111/8168B .

I used the default driver back when I was a noob at Linux (still am) but then I had the brilliant idea to download the dedicated driver. How can I revert it to use the built-in linux one? just sudo pacman -R r8168?

EDIT: Forgot about google, I'll change it to r8169 and post outcome.

Re: [SOLVED, driver issue] Ethernet enp6s0 broken after update.

just sudo pacman -R r8168?

Yes.

I have this revision:

05:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 06)
	Subsystem: Gigabyte Technology Co., Ltd Onboard Ethernet
	Kernel driver in use: r8169
	Kernel modules: r8169

It's no need to reboot but I will be better to reboot big_smile It's really weird hardware.

Then just try to enable NetworkManager with default settings, etc. Remember to also enable NetworkManager-wait-online.service.

EDIT:
Check system logs as I wrote before.

Based, after switching said drivers internet is reliable again. Before I mark it as solved, what was the cause of those drivers failing?

I'll supply them tomorrow as right now as I'll have more free time on my hands and I can install the r8168 driver again, because logs now dont contain that internet issue.

Re: [SOLVED, driver issue] Ethernet enp6s0 broken after update.

I don't even try to inquire it. There was a period, don't remember when, that r8169 doesn't work well, so I've tried to use r8168. There was even worse, total freeze, no usb3.0, etc.

Maybe it depends on platform... and chipset revision. I don't know.

Check parameters of interface, R8168 it's gigabit, so check this way - should be 1000Mb/s with full duplex:

sudo ethtool enp6s0

Check system logs in case of any errors, as I wrote above.

EDIT:
No, if r8169 works as it should, it's not necessary to install r8168. Just check in several days if current setup with r8169 is stable and doesn't cause strange, any additional errors.

Re: [SOLVED, driver issue] Ethernet enp6s0 broken after update.

r8169 had massive issues in the early 6.4 kernels, https://bugzilla.kernel.org/show_bug.cgi?id=217596 - likely the reason why you went for r8168?
And then the out-of-tree driver has probably fallen behind changes in the 6.5 kernels.
(What's bewildering is the complete silence of the failure, no crash nor any kind of TCP errors…)

Historically, support for the RTL8111/8168/8411 chips is one-off, so be ready to try r8168 if you start getting trouble w/ r8169 in the future and don't hold a grudge wink

Nah, it was back when there were 5.x kernels and I had a network speed of Kb/s, as it turned out it was the ISPs issue but I kept the driver
