No network in OpenSUSE 13.1

English Network/Internet
#1

I just installed OpenSUSE 13.1 32bit GNOME. My network’s not working. I generally plug in a cable from the modem into the computer. It’s open network and generally does not require any configuration. It was working fine on OpenSUSE 12.3. Also, the GNOME icons (like the ‘cross’ icon for close, ‘power’ icon on top right etc.) are not popping up. When I click ‘power off’, the icons appear just as the system begins to shutdown. When I go to the network option from ‘system settings’ a message pops up as “Network not supported” or something like that. (This used to happen in 12.3 too. Since my network is open, it did not lead to any problem. But, I could not connect to any wireless network in 12.3 also). Is there any way to bring back the network? I also use Ubuntu 12.04.3 LTS where network is working fine and I have shared the same home folder between OpenSUSE and Ubuntu.

Thanx in advance…

What do you mean with “system settings”?
If you want to use the GNOME network applet to control your network, you have to switch to NetworkManager (YaST->Network Devices->Network Settings->Global Options), otherwise you have to configure it in YaST.

What network cards do you actually have? Maybe you need a driver or firmware…

Awesome! Switching it to GNOME Network Manager using Yast did the trick! Now, I can access the Internet… Also, I have solved the GNOME no-icon problem using the tweak-tool.

THANX A LOT!!!

Similar situation: Installed 13.1 from a boot DVD and it found my NIC card but couldn’t find a connection. Once desktop loaded networking was disabled. Checking the box in the Network Management to enable did nothing. YaST > Network Devices > Network Settings > Overview tab showed controller was ‘unconfigured’. Hit edit on the controller and it had for some reason decided to assign my controller as static IP…

I have a RTL8111/8168B PCI express Gigabit Ethernet Controller

Now working.

I offer this piece of advice to those to whom it might apply, as it did to me. After having read this posting, which I didn’t feel helped me all that much (I have KDE only, so there is nothing to switch between… the person who originated this post, americast, had both KDE (Ubuntu?) AND Gnome installed), I did some hardware checking, because just prior to the problem (when I couldn’t connect, and when the router lights showed only one PC light blinking, I checked on the plugin to the ethernet card in the back of the desktop to see if the lights there were working, and they were not), I has erased my two HDDs (because I messed up my first install of openSUSE 13.1) and had just done a fresh reinstall, so I wondered if maybe the DBAN wipe (DoD Short) had konked out the Bios setting, or some such.

So, before powering up again and going into BIOS to see if a setting there had been turned off, I opened up the machine to see if maybe I had disturbed any of the wiring (I had also just installed a third HDD, which I have yet to plug in, and may never - though that is neither here nor there! : -) - but in the process of installing the third HDD, I monkeyed around a lot in there, because I put it in an entirely unconventional - but superior! - place). Well, that ethernet card - not one of those flat thingies that one installs in the ethernet bay below - has no external wiring whatsoever, so I decided that this simply couldn’t be the source of my problem, which, I figured, MIGHT, after all, be ethernet card failure.

However, I know from experience that a REBOOT often solves many unexplainable issues (it happens with our modems regularly, eh?), so I put humpty dumpty back together, powered up, and hit F2 to take me into BIOS, but used the pause to see if the ethernet card lights in back were on… THEY WERE!). Quickly out of BIOS and back to the ramp to openSUSE and, once arrived, everything was just fine, or fine enough that I could go to Yast and activate my network settings, and as soon as that was done, I got a message that there were 189 updates waiting for me to install (remember: I had just done a fresh reinstall).

So, summa summarum: when it doubt, boot it out (the problem, that is: i.e., try a reboot!)! : -)
