Lost my eth0

[Urza9814]

So my main internet connection is wireless, on wlan0. However, I have a built-in ethernet on my motherboard that I'm trying to use for Mandriva's internet connection sharing. However, the interface eth0 doesn't exist, and when I try to run drakconnect to create a new ethernet connection, it detects the network adapter fine (Sundance Technologies Inc / IC Plus Corp | IC Plus IP100A Integrated 10/100 Ethernet), but when I hit next it says 'Unable to find interface for selected device (using sundance driver).' I know it used to exist, and I think it may have been somehow removed while trying to bridge wlan0 to my VirtualBox VMs. My question is, how do I get it back?

 

Here's the output of ifconfig too:

the eth0 interface should be created as soon as the driver is loaded. If it's not, that means there's a problem with the driver. There may be some useful error messages in the file /var/log/messages .

[Urza9814]

I'm not seeing anything bad at all in /var/log/messages. But I think the problem might be that eth0 was removed after the driver was loaded. I've been trying to find a way to reinstall the driver, but I can't seem to find any.

Does the hardware present in lspci?

Whats the ouput of lspci?

 

I am just asking this cause it happened to me ....some strange hardware conflit which my ethernet card was not listed in lspci....I had to change some pci card to another slot...and back again...weird!!

yup, it's showing up fine there:

02:0a.0 Ethernet controller: Sundance Technology Inc / IC Plus Corp IC Plus IP100A Integrated 10/100 Ethernet MAC + PHY (rev 31)

Perhaps a reboot would help?

and check dmesg for some module loading error.

In my system:

eth0: VIA Rhine II at 0x1e400, 00:01:29:4e:05:35, IRQ 10.

eth0: MII PHY found at address 1, status 0x786d advertising 01e1 Link 45e1.

eth0: link up, 100Mbps, full-duplex, lpa 0x45E1

 

the dmes line for my ethernet card,its a via rhine II onboard network card.

 

Check for something like that in dmesg.

Also if you configure the network card from mcc,if module loading or another error when configuring network card,you should try running mcc from a konsole as root....drakconnect tend to be a bit verbose,you might have a chance to see why the card doesnt work in the konsole if not in /var/log/messages or /var/log/syslog.
