Wired connection works on his own way

English Network/Internet
#1

Hello

I’m using OpenSUSE on my HTPC since 11.3 version. No hardware or LAN changes since then. However, from OpenSUSE 12.2, wired conecction is working his own way. Even now, when I installed from scratch OpenSUSE 13.1, the same problem. The problem is this: When I boot OpenSUSE, mostly Network Manager plasmoid says “No wired connection”. But the wire is connected and the LAN it’s working ok. However, if I enable/disable repeatedly “Enable networking” on the NetworkManager plasmoid (see images in https://spideroak.com/browse/share/CompartidoSpiderOAK/Images , “Habilitar redes” in my Spanish KDE interface), finally, OpenSUSE detect my wire is connected and all works fine. If I reboot my machine or suspend it or even I disable and enable “Enable networking” option in network manager, it can or not appear wired connected, and must repeat the trick … enablng and disabling repeatedly the network. I even tried to manage the network configuration with “ifup”, but the result was the same, so finally I’m working with NetworkManager but I’m tired of do the trick.

The screenshots show the different states and info in the two situations, but the cat5 cable is always connected despite OpenSUSE said it’s not, and, yes, I tried with other computer on the same cable and worked fine.

Please, any suggestion?

Thank you

When I interprete this correctly, you talk about openSUSE13.1. But in 13.1 there is normaly no eth0. Thus I am interested on how you got the information you show.

And please remember that we like computer text copied/pasted completely (prompt and command you used, output up to and including next prompt) between CODE tags in a post. You get the CODE tags by clicking on the # button in the toolbar of the posteditor.

First, thank you. I didn’t take into account the QUOTE tags and the command given to obtain the data I pasted. And you are not wrong: Is OpenSUSE 13.1. Even this computer where I am writing is OpenSUSE 13.1 and have eth0 and eth1. Anyway, this is the info I think could be interesting:

try to set up statci route thorugh yast->network devices. try to read this thread https://forums.opensuse.org/showthre…t-script/page2

Hi Roberto. I read the article. In fact, as a last try to solve my problem, I had assigned in my router a static IP for the MAC of my HTPC (as you can see in the image), but that didn’t solve nothing. The problem persist and I must do the trick of “enable/disable” networking. I don’t know if I can see detailed information in some log file about what’s happening each time I enable or disable networking, cause maybe it will show any evidence about the error.

Thank you in advance

Hi faleloncio,
I think you got that wrong. Roberto was referring to a static route from your HTPC to your router using YaST on your HTPC.
The output of

route

might then be of interest.

This is what route command show me:

# route

I just wake up my HTPC from Suspend mode and, as I was guessing, NetworkManager said that there was not a wire attached :(. Taking a look to dmesg, we can see an entry for each time I enabled/disabled networking till magically NetworkManager accepted my wire is plugged :sarcastic:.

I begin to think is some kernel problem, cause is only happening from a version and not after that version.
