No Internet with Live CD or Installation (Realtek 8111)

Support Network
#1

I’m having a real problem here. My Manjaro installation got corrupted so I decided to reinstall with the latest version. However I discovered that I have no internet on either the live cd or after I install. I have the dreaded Realtek 8111 chip, so I think that’s the problem. The question is, how do I fix this? I have access to another computer that I can download something onto a USB key if need be, but I don’t know what to do.

Oddly enough, before my installation corrupted itself everything was working fine and I was up to date with the latest kernel so I don’t know what happened.

#2

I managed to restore my system from an old backup I had and the internet is working again. It’s not the driver because it’s using the latest one which is the version that supposedly doesn’t work (r8169). Perhaps my router didn’t like me reinstalling the OS?

Hi @tempest2084,
Please, post the output of the terminal command inxi -Fazy here.
Meanwhile, you could take a look at this post in the forum.

Read inside the post which includes your realtek 8169 card.
You could also search for another solutions in the forum typing realtek 8169.

Hope it helps, regards

Hi @tempest2084 ,

In the following post it is said that you have to build the driver from source. The reasons are at the end of the post.
https://forum.manjaro.org/t/r8125b-still-not-runninng/54201/5´

Hope it help, regards,

#6

But why is it working now after I restored my system? I know I never did anything like building a driver from scratch.

#7

Hi @tempest2084 ,
I apologize for the previous post, I understood you have problems with your wifi card and not with your ethernet one.

Regards,

#8

I dont have a wifi card, just the built in ethernet

#9

Hi @tempest2084,
Please read what @megavolt wrote on the following post in order to see what is happening to your ethernet adapter.
‘Ethernet disappeared after trying to update’

Hope it help, regards

Manjaro KDE connects to the internet, but the installer says there is no internet connection
#11

You could try this since it is the same chip-id there (10ec:8168).

#12

Manjaro Settings Manager GUI can install linux510-r8168
and create a file /etc/modprobe.d/r8169_blacklist.conf to blacklist the r8169 driver
Network-8168 and network-8169 works really bad with my computer

Or this command

sudo mhwd --install pci network-r8168
