I'm using OpenSuse 12.3 with a Gnome interface. I am able to connect to any wireless network but my network manager just stopped recognizing wired ones. I'm not even show the "wired connection" menu. Everything was working fine until I disabled graphically the wired connection (by clicking off). Since them I am unable to use any wired connection. Here is the output of ifconfig -a:

eth1  Link encap:Ethernet  HWaddr C4:46:19:0E:D4:18

netstat -rn outputs this :

and iwconfig this :

      Rx invalid nwid:0  invalid crypt:0  invalid misc:0

lo    no wireless extensions.

Can anyone help me?

OK, eth1 - wireless interface. Almost sure that eth0 wired interface. Try :

~# ifup eth0

and check your interfaces with ifconfig again.


Update:

Hmmm...

systemd-udevd[343]: renamed network interface eth0 to eth1

I think your MAC address of eth0 was changed. Read more here. Try to comment eth0 record in /etc/udev/rules.d/70-persistent-net.rules and reboot.

ifup eth0 outputs "Interface eth0 is not available". By the way I'm on OpenSuse and the network is by default handled by NetworkManager so I had to manually switch to ifup. –  iamdede Jul 7 '13 at 18:11
    
@iamdede please provide output of ifconfig -a instead of ifconfig –  september Jul 7 '13 at 18:22
    
OK I have edited my post again. –  iamdede Jul 7 '13 at 19:18
    
Try to restart network # /etc/init.d/network restart according cyberciti.biz/faq/… –  september Jul 7 '13 at 19:41
    
It didn't work, and that's what I expected as it doesn't change when I restart the computer neither. –  iamdede Jul 7 '13 at 20:49
