Network disappeared

Might as well be a newbie on this one. In my EnOS build, suddenly I don’t have any network access (wired - no wifi). Might have come from an update somewhere, but unlikely. Might be hardware - but unlikely.

I say 2 causes are unlikely, because the same hardware running Arch, and running Garuda - do NOT have the issue. As they both are on the same hardware, and have the same updates (with minor differences, none known to be hardware specific) - it has me baffled for the moment. It has been so long since I even HEARD of a network problem like this, I don’t even know where to look!

Journalctl returned thousands of copies of 3 lines about cups - not sure of relevance. I can get whatever, but obviously can’t post from the ‘stricken’ patient - so I’ll gather when I have a few possible targets identified :grin:

Thanks in advance - I guess it’s another learning opportunity!

If you have the package r8168 installed, try removing it:

sudo pacman -R r8168

and after rebooting see whether you get your network connection back. It’s somewhat of a long shot, but I noticed this package comes installed by default on EndeavourOS, but not on vanilla Arch, so that could possibly explain why one works and the other doesn’t.

So this rules out the possibility of having the cable unplugged. :wink:

But can you use USB tethering if you want to send any journals, logs, etc.?
Also, you can save any logs to a file and send it from another OS…
By the way, does the EndeavourOS USB installer’s network work?

eos-log-tool could be your friend :wink:


You didn’t happen to put any kernel parameters on your system to rid some of the error messages. I had done that after updating my UEFI because it now has these entries for no vector IRQ blah blah and it was fine until i hit the newer 5.7+ kernels and then i lost wifi but not ethernet. Then i checked and there were mega errors in dmesg so after i removed the parameters it was good. But i have to put up with the those messages on boot up.

This is part of the ‘hard-to-figure’ part of this… No particular changes made, the only unusual thing I’ve done is IgnorePkg linux temporarily because of ‘oddities’ reported with 5.8.8 (still on 5.8.7) - but that’s true of all 3 systems I mentioned. About all that happened (apart from updates) is some browsing, and some bash coding/testing - and I spread that across systems too (including on the live EnOS).

Off to try some stuff - and perhaps gather some logs…

2 good ideas - especially because I don’t seem to have any! Back awake now - will start the journey…

Do you have a compelling reason to not use linux 5.8.8?

No - just sounded like trouble on the way (GParted etc) - I guess I could try that too! BTW - I am on the live installer right now, so that’s not a problem.

Could I have ‘un-matched’ the kernel with other things accidentally? That’s the next check :grin: Thanks for the thought!

I guess the gparted problem will be sorted soon because it is used so much.
Fortunately there are other tools that can do about the same as gparted.

Apparently I am one of those tools :grin: I popped 5.8.8 back on, and I am back on EnOS without any perceptible problems…

As is no surprise to anybody when an EnOS install has a problem, it is most likely ‘user failure’! Looking back at it, I might not have downgraded the linux-headers at the same time as linux - leading to a mismatch - and the result was no network access! I would have expected something more dramatic than that - but I also would have expected to be smarter (sigh).

Thanks for the help and suggestion - that was self-generated problem!

Partial downgrading can bring very strange issues, and this is a living proof! :smile:

Anyway, gparted seems to fail here too, but I just installed partitionmanager and that seems to work (although I think it is not as nice as gparted…).

One can always go back to fdisk :grin:

Speaking of living proof - here is the exemplar of:

to fix a problem - first undo the last thing you did! Doesn't matter if you don't think it's related - it probably is!

BTW - the 'Change resolution' added to Welcome really hits the spot on installing on a high dpi screen! Should earn a favourable review mention on the next one up...
