No Ethernet on Gnome on Z490

hey guys,

So basically, i booted up manjaro to install it from USB, and i have no ethernet which is really odd,

My motherboard is a Z490 MSi Gaming Edge.

It detects my wifi ( i dont have the antennas attached ) cause i dont like wifi and mostly use ethernet, usually in the old days we had trouble with wifi, ethernet was always detected by default

:+1: Welcome to Manjaro! :+1:

Please read this:


and post some more information so we can see what’s really going on. Now we know the symptom of the disease, but we need some more probing to know where the origin lies…

:innocent:

Sorry that took so long, had alot going on

i can clearly see my ethernet card there but it wont show up in my settings, im having to tether of my phone for now, the Realtek semi is my ethernet controller, all i see is vpn and proxy

  1. Could you edit that and when providing code/output, please copy-paste it in-between 3 backticks at the beginning and end of the code/text ``` so that the output looks like this:

    Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
    Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
    Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur.
    Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.
    

    instead of like this:

    Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.

    (as that makes our life much easier so you get helped more quickly and efficiently)

  2. Also if you provide the network section of an inxi --full --system --admin --verbosity=7 --no-host --filter it will give us more information than just an lspci as inxi will also tell us whether the Ethernet driver is loaded or not.

:innocent:

Hey there,

Sorry about my previous ill try and use the code thingy.

You’re on:

which is EOL, so as a first, can you add the 5.8, 5.4 LTS and 4.19 LTS and see if that does the trick?

  • Log off

  • Switch to TTY2 by pressing Ctrl+Alt+F2

  • Log in there

  • Execute:

    sudo mhwd-kernel --install linux58
    sudo mhwd-kernel --install linux419
    sudo mhwd-kernel --install linux54
    
  • to ensure grub is showing, execute:

     sudo nano --backup /etc/default/grub
    
  • Change (or add?) the following 3 lines:

    GRUB_TIMEOUT=3
    #GRUB_HIDDEN_TIMEOUT=0
    #GRUB_TIMEOUT_STYLE=hidden
    

    (3 or higher is fine, add the # before the lines above if those lines are present)

  • Ctrl+X Y Enter to save if there is anything to save

  • If you did save, execute:

     sudo update-grub
    
  • Reboot

  • Go to grub’s Advanced options

  • Choose these kernels one by one and try them out one by one in the following order: 5.8, 5.4, 4.19 and see if that helps.

If that doesn’t help, we might have to build the latest and greatest Realtek RTL8125 from source, but before we do that, please rule out any hardware problem and:

  • get a brand spanking new Ethernet cable
  • Hook that up to another port of your router / switch / hub / …
  • Reboot said network equipment just to be 100% safe.

:innocent:

hey fabby thank you for all this advice.

I will have to do it on the weekend so apologies for the delay, work has me busy this week.

hey everyone and @Fabby

I fixed it finally, i found this little script on github which did it all for me and it worked straight up with kernel 5.8 from the latest manjaro 20.1 installation.

In the future, please mark a solution like this:

so that the next person that has the exact same problem you just had will benefit from your post as well as your question will now be in the “solved” status.
