I have an ASUS N76VZ laptop with openSUSE 12.2. It detects only the wireless card and my Android phone in USB tethering mode. The wired LAN card is detected and works only in Windows.

I'm using NetworkManager to configure interfaces. YaST network configuration, which can operate only in ifconfig mode, detects the card and greys it out ("not configured" under IP column).

How can I enable my wired card on NetworkManager?

[Add] Ran collectNWData script. It reports an error about wlan0 but I'm not interested in wlan0

!!! CND0240E: networkmanager for network configuration enabled but a YAST network card configuration for wlan0 exist

[Add] Maybe I've got more info. YaST network configuration, when I switch to ifconfig mode, reports that the kernel device for the wired card is not present. "This is usually caused by missing firmware for wlan cards. Check dmesg output".

What do I have to look for in dmesg?

You can either use ifup/ifconfig or the NetworkManager - not both at the same time. In YaST, you can chose between the two options. Ensure, that the network is in fact managed by NetworkManager. Then configure your card with the NetworkManager in your favourite desktop environment. –  ernestopheles Jan 14 '13 at 10:57
    
But I see no way of configuring the card in KNetworkManager, the wired connection tab is greyed. Only wireless, VPN and DSL are available. And I want to use NetworkManager instead of ifconfig –  djechelon Jan 14 '13 at 11:30

It appears to be a configuration problem of some sort. For diagnosis, please have a look into the following script: collectNWData. It is designed to investigate your entire network configuration and gives a decent readable output.

Carefully read the manual, download the script, run it, analyse the output - and if in doubt - please post the output here.

I have pasted the full dump because no meaningful error was reported. But I found interesting things in the dump: it finds the ethernet controller but doesn't report any ifcfg configuration for it. But shouldn't NetworkManager take care of that? –  djechelon Jan 18 '13 at 8:13

The solution was to install the alx driver from source. I can't currently find again web references for it
