Hi,

I got this new desktop just today but I am having trouble to get the internet working. It doesn’t have a wifi card. Some specs are as followed:

Reluctantly I had to start up Windows to check if it wasn’t a hardware issue. It wasn’t. I also tried a couple of other Live iso:s (Fedora 34 and Linux Mint 20.1). No internet connection there either.

Please let me know if there is other info you need to troubleshoot this.

Maybe it’s the r8168 / r8169 problem?

Fire up welcome and see if there is a button that says remove r8168. If so click it and then reboot.

Does that mean when I see this button that I necessarily have this problem, even if my Ethernet seems to be working fine?

Thanks @Elloquin and @Endlich,

I didn’t have the removal button. I looked around the forum and saw it was introduced by @manuel in another tread. In the same tred, there was a post by @joekamprad. Tried that and it didn’t work. Here it is:

You got a new desktop? 4750G? I’m waiting for them to get some Ryzen 7 4700G processors. :tired_face:

Edit: Now i jealous! :laughing:

Did you try remove r8168 and reboot?

No it is there for situations like this when it is installed and caused ethernet issues. Uninstall it and r8169 is used. It is a hardware based issue with certain systems.

Are you fully updated? also post inxi -Fxxxza --no-host

I got it it delivered today. I had been looking at it for some time and it was out of stock at my web retailer. Yesterday I checked and they had only 3. . It’s a pretty nice machine.

@elloquin, @ricklinux

I just tried the live os. This machine doesn’t have a wireless card so I am not sure if I get EnOs installed, how I would go about and update.

Are you not getting Ethernet on the live ISO is what you are saying?

1 Like

Yes, on the live os.

Maybe @Elloquin has the same idea? If you sudo rmmod r8168 and sudo modprobe r8169

In the live os I did:

sudo pacman -R r8168
sudo rmmod r8168
sudo modprobe r8169

as per the link I posted above from @joekamprad. Unfortunately it didn’t work.

Well the package r8168 is on the live ISO and removing it probably only removes it from the Live environment so when you reboot does it show the same one as being loaded?

Edit: The r8169 is a kernel module that will load if you can blacklist or remove the r8168 in the live ISO?

Hmm, I guess so. Or rather I assume so. I am gonna fire up the live iso now. How would I check that? Sould I run the same commend as above or something else?

Did you try this and reboot? As per @manuel from the wiki?

sed -i /usr/lib/modprobe.d/r8168.conf -e 's|r8169|r8168|'

No. But wouldn’t rebooting set everything back to the “original” state of the live iso. I mean I could do a offline installation and then try it perhaps? I would rather have had Cinnamon but I could install it afterwards and remove Xfce.
