I’m going to come right out and say I am a complete novice with Linux/SUSE. The equipment I’m having a problem with is a little web-server that was purchased by my employer that has, quite suddenly, stopped functioning. I was changing the IP address within YaST, at which point the device offered to update itself, which I saw no harm in. Post-update, however, I was unable to so much as ping the device.
I tried “ifconfig eth0”:
“Error fetching interface information: Device not found.”
I went into network settings via YaST and found that there are two cards now listed as:
RTL8111/8168B PCI Express Gigabit Ethernet controller
Both IP addresses are “Not configured”. The information pane, for both cards, cites:
RTL8111/8168B PCI Express Gigabit Ethernet controllerBusID : 0000:02:00.0
Unable to configure the network card because the kernel device (eth0, wlan0) is not present. This is mostly caused by missing firmware (for wlan devices). See dmesg output for details.
The only difference in either of the cards is the BusID (0000:02:00.0 and 0000:03.00.0)
I can neither edit nor delete either of these cards.
As I mentioned, I am a total Linux novice, and am at a total loss for what to do next, or even how to find critical information about the system itself. I know enough to check dmesg, but not enough to have any clue what to look for in the output.
Any and all help would be greatly appreciated at this point!
