Hi,

I do have ethernet when booted into Manjaro, Archbang or win10 on same computer with same ethernet cable
Wifi is working

I have the following results:

sudo modprobe r8168

Can anyone help me please?

As far as I know you were given the option to choose the r8169 or r8168 driver during install, default is r8169 which works fine for most people.

Could you provide inxi -FAZ --no-host | eos-sendlog

and sudo dmesg | grep r81

Also prvide output of sudo lsmod | grep r81 please

Looks like the driver is not loaded and I dont have the knowledge why that happened. I think you can load it manually like so:
sudo nano /etc/modprobe.d/ethernet.conf

and paste the following in there:

options r8169

Save the file and reboot.

5

sudo lsmod | grep r81 gives no output

options r8169 rather than r8168 ?

6

Yes r8169 should be fine

7

no luck

sudo nano /usr/lib/modprobe.d/r8168.conf
shows r8169 blacklisted

No idea what that’s all about but is from my initial searches before asking here

8

Remove that line that says blacklist r8169 and save the file. That should do it. Or remove r8168.conf completely.

9

sudo pacman -R r8168

file /usr/lib/modprobe.d/r8168.conf is from package r8168.

cd /usr/lib/modprobe.d

ls

delete that file and reboot:

sudo rm -r /usr/lib/modprobe.d/r8168.conf

Nearly!
That didnt work but when took the blacklist r1869 line out of /usr/lib/modprobe.d/r8168-lts.conf it worked!

Thanks!

Before I mark as solved - what did I just do?
Did I swap from r8168 to 8169 drivers?
Can I now uninstall r8168 and r8168-lts?
Why did I have that problem - is there a problem with the r8168 drivers?

11

Yes do what @anon50380917 said and mark his answer as the solution.

Thanks!
I did pacman -R for r8168 and r-8168-lts

Since there were then no r8168.conf of r8168.lts files in /usr/lib/modprobe.d I didnt need to remove them
